2. Mounting of HYDROCAL 1002-1003 unit 2.1 Locations for installation of HYDROCAL 1002-1003 To ensure the correct function of the HYDROCAL 1002-1003 the location of mounting is very important. For a typical transformer, three places are possible:
Pos. 1
On return side of cooling circuit: Please install the unit on a straight piece of tube on the cooler output between the cooler pressure , the unit must absolutely be and the main oil tank. In order to avoid negative pressure, mounted on the downstream side (after the bend) of the oil circulation pump. Remark: Choose this place only in case of continuous oil flux through the cooler.
Pos. 2
Flange below on the transformer tank: The flange must be at minimum height of 30 cm in order to allow installation and mounting of HYDROCAL 1002-1003 unit.
Pos. 3
Upper filling valve: It is possible to mount the HYDROCAL 1002-1003 unit in this position, however it may be difficult to operate and read the data of the unit. Remark: Should the unit be mounted on the wall of the cooler, then make sure that the unit is mounted below the oil level. l evel.
Pos. 4
Never install install the HYDROCAL 1002-1003 unit on top of the cooler cooler or on the suction face of the pump.

2.2 Security precautions for installation The following security precautions must be strictly observed during the installation. Otherwise no warranty claims will be accepted. Never connect the sensor head to another HYDROCAL 1002-1003 electronic unit other than the delivered one. The components are delivered as a matched pair and have been calibrated together in our works. You will find the serial numbers on the units, on the packing material and /or on the data sheets. Please ensure you note down these serial numbers for future reference. Never remove the protection cap from the sensor before you are ready to mount the unit on the valve of the transformer . The protection cap protects the membrane of the sensor against dust and other foreign bodies. Additionally it protects the thread of the measuring head and/or adapters. Note: Use the protection cap also after dismounting of the unit. Never touch the membrane with fingers or other objects.
Never close the aeration hole for oxygenation.
Never use or stock chemicals with hydrocarbon contents near the measuring sensor. Never clean the measuring head with solvents, because its gases will strongly impair the measuring accuracy and the sensivity of the sensors.
HYDROCAL 1002-1003: Manual for installation and operation
Page 6 of 97
Never apply a negative pressure to the measuring head. Negative pressure can damage the unit.
Remove the HYDROCAL 1002-1003 unit from the valve every time you degas or refill the transformer. Never install the HYDROCAL unit on a valve that is closed for a long period of time. Remove the unit if this cannot be avoided. Never install the HYDROCAL 1002-1003 on the suction side of the cooling pump! Never install the HYDROCAL 1002-1003 unit on an elbow or curve of a tube. The unit can be damaged by negative pressure produced by turbulences in curves. Never install or remove the HYDROCAL 1002-1003 without opening first the aeration screw. Never use galvanized fittings or valves to mount the HYDROCAL 10021003 unit. Galvanized fittings or valves can react with oil, this will produce incorect measuring values. Never clean the HYDROCAL 1002-1003 unit with high pressure cleaning equipment. High pressure cleaning equipment used to clean transformers can seriously damage the HYDROCAL 1002-1003 unit.
HYDROCAL 1002-1003: Manual for installation and operation
Page 7 of 97
Never use a chaining key tool for mounting. Use of such tools can damage the surface of the measuring head and the threads. Please use an adjustable thin spanner for 1 ½“.
Attention!!! Faulty or inappropriate handling of the sensor head like perforation of the membrane, scratches on the membrane or damages by negative pressure, paint or solvent liquids make the warranty invalid.
2.3 Preparation for installation Before installation, a visual inspection of the membrane must be carried out made. Remove the protection cap and check the membrane. No cuts or tears should exist, the surface must be smooth. Under no circumstances should the membrane be touched with fingers or with any other means. 2.3.1 Power supply for the unit The HYDROCAL 1002-1003 unit requires an auxiliary power supply of 110 / 230V close to the unit. The power needed is max. 350 VA. 2.3.2 Requested tools: •
Long Allen key, size 4 for aeration screw
•
Long Allen key, size 5 to loose the measuring head from the unit (6 x screws).
•
Bucket, oil absorber, cleaning rag
•
Teflon-band
•
Drill / screw driver
•
Digital multimeter
Tin spanner or adjustable tin spanner of 1 ½“ for valve and fittings To seal the thread of the measuring head, only Teflon band must by used. Minimum 4 to 5 layers must be applied. •

2.4 Installation of the HYDROCAL 1002-1003 unit
Attention!!! Mount the measuring head horizontally on the valve. The aeration screw must then be in the 12 o clock position. Please mount the HYDROCAL 1002-1003 unit on a valve with full opening (full bore valve) or a ball valve with an internal thread of 1½” (DIN ISO 228: G 1½). The HYDROCAL unit has a 1½’’ thread (Dimensional drawings, see. chapter 6). A good oil flux should exist on the mounting location. If necessary, use a reduction piece (adapter). In order to have a sufficient oil flux on the membrane, the diameter of the valve should be not less than 25 mm. For optimal working conditions, the valve diameter should not be more than 76 mm. The valve must be on earth potential.
Attention!!! The distance between the oil main stream and the measuring head shall not be more than 6 times the length of valve diameter. (Distance 150 mm at Valve-∅ 25 mm / Distance 228 mm at Valve-∅ 38 mm / Distance 300mm at Valve-∅ 50 mm / Distance 450mm at Valve-∅ 76 mm).
In case there exist strong vibrations on the mounting valve, the valve should be relieved by a support. Then mount the unit according to the following steps: •
Loose the knurled thumbscrews and remove the housing of the HYDROCAL 1002-1003 unit.
•
Disconnect the connection cable of the measuring head from the printed circuit.
•
Loose the measuring head from the unit.
Only remove the protection cap (slowly while turning) when you are ready to mount the measuring head!
HYDROCAL 1002-1003: Manual for installation and operation

•
Clean the internal side of the installation valve.
•
Wind 4 to 5 layers of Teflon band on the thread of the adapter and mount it on the valve. Make sure that it is fixed mechanically.
•
Mount the measuring head on the adapter taking care. Not to use too much force. In case no adapter is required, wind 4 – 5 layers of Teflon band on the thread of the measuring head and mount it on the valve. Make sure that it remains fixed mechanically, but do not use too much force.
•
Turn the aeration screw to the 12 o clock position.
Attention!!! The following steps must be done according to the company procedures. Work carefully in order to prevent air entering into the transformer. Use a bucket to catch oil coming out. •
Unscrew the aeration screw 3 – 4 turns with Allen key No. 4. (Aeration is active).
•
Open the valve slowly until oil comes out on the proving hole.
•
As soon as no air bubbles sort on the proving hole, close the aeration screw. Then fully open the valve. Remove the oil from the measuring head external.
Do not use any solvents for cleaning! •
Make sure that no untaught places exist.
•
Mount the unit on the measuring head, use the 6 pieces of plain washers, lock washers and nuts.

•
Connect the connection cable to the printed circuit. Check that all pins of the plug go straight into the socket; pushing the plug in carefully.
•
Use steel protected cables for power supply, alarm-cables and communication cables and connect them to the appropriate connectors.
•
Put the housing in correct position and secure it with the knurled thumbscrews.
•
Connect the power supply to the HYDROCAL 1002-1003 unit. The display shows the specified conditions confirming that the HYDROCAL 1002-1003 is functioning correctly.
•
The measuring cycle of the HYDROCAL 1002-1003 unit is synchronized on the hour mark, this means the first measuring value is available approx. 2, 22 or 42 min. after the hour mark and can be read on the display.
•
To check the heating function, touch carefully the heat plate after some minutes.
Attention, danger of burning!!! The heating plate should now be warm. Should the resistor heating not function correctly then check its contacts. •
After first start-up, in all cases date and time have to be checked on the HYDROCAL 1002-1003 display and eventually have to be adjusted manually in clock settings (chapter 3.7.5.3) or with HydroSoft (chapter 4.10.7).

3. Software on Hydrocal unit 3.1. General information The gas-in-oil analyzer HYDROCAL 1002-1003 is based on a microprocessor controlled measuring system. A 32 Bit „Coldfire“ processor with a clock frequency of 50 MHz is used. The software has been developed with the language „C“. The system has a static memory of 4 Mbyte for measuring data. This offers a 2 years time storage capacity for the measuring data. After this period, the oldest data will be overwritten by the latest values. When using additional external sensors, the storage capacity depends from the number of sensors and the time interval selected for storage. The following formula can be used to determine the storage capacity: 4 ⋅10
Memorydept h[days ] ≈
6
[ Byte]
8
[
] ∑ 288[ Byte / day ]⋅ Sensorstor agesn [1 Std ]
5664 Byte / day +

With one additional sensor with a time interval of 5 minutes the following calculation results: Memorydept h[days ] ≈
4 ⋅10

]
≈

≈ 438[days ]
Also an additional reduction of the storage time takes place by the definition of alarms. Each change of alarm status requires 12 Bytes. Attention: To avoid any loss of data, it is proposed to read out regularly the measuring data by the Windows based software “HydroSoft”.

RS 232 / RS 485 setup
The serial interfaces configuration is made in the following menu.
This section illustrates different ways to communicate with HydroCal devices. There are the following main connection / communication scenarios: Host (PC) with one HydroCal device via RS232, RS485 or via Modem • Point-to-Point Host (PC) with many HydroCal devices via RS485 bus • RS485-Bus Host (PC) with many HydroCal devices via RS485 bus using a HydroCal bridge • Bridge SCADA System with online monitoring of one or more HydroCal devices • MODBUS General The following sections describe how to configure the Hydrocal devices and the HydroSoft software. After a short description screen shots of HydroCal and HydroSoft illustrate the setup. Some descriptive comments and hints may follow the screen shots. The setup of the HydroCal has to be carried out manually on the device.
A. Point to Point A point-to-point connection / communication is the simplest setup. The host (PC) is connected directly to one HydroCal device. The connection can use the RS232, the RS485 or the modem. The default configuration for a HydroCal device assumes a point-to-point connection. The same applies to HydroSoft. I. RS232 The RS232 is used for short connection distances (less than 10m). It provides full duplex and handshaking.
HYDROCAL 1002-1003: Manual for installation and operation
Page 44 of 97
HydroCal
HydroSoft
The setup is very simple. Just assure that the baudrate is matching and that the correct COM port is chosen in HydroSoft. II. RS485 The RS485 can be used for long connection distances (up to 200 m). It is implemented as a two-wire interface with half-duplex and a soft-handshake.
HydroCal
HydroSoft
Assure that the baud rate is matching and that the correct COM port is chosen in HydroSoft. Also check the RS485 checkbox to indicate the half-duplex connection. A RS485 adapter might require some special setup of the other checkboxes.
HYDROCAL 1002-1003: Manual for installation and operation
Page 45 of 97
PC RS485 Adapters Connecting a PC to the RS485 of a HydroCal device usually requires an adapter (interface converter). Depending on the properties of the adapter in use, the RS485 related check boxes in HydroSoft must be set accordingly. For communication with a HydroCal device only the two-wire half-duplex mode is of interest. This mode requires a kind of send/receive-control which is either ART (Automatic Receive Transmit control) or a manual control (e.g. via the RTS signal). Further the adapter may echo the send out data. The two checkboxes in the HydroSoft Connection dialog must mirror the properties of the adapter: •
Ignore Echo Must be checked, if the adapter echo the send out data
•
RTS Send Control Must be checked, if the adapter requires a manual send/receive-control via the RTS signal (this assumes a RS232 to RS485 adapter is in use)
Answer Delay If an RS485 adapter with RTS send control is used it may be necessary to set up some answer delay in the HydroCal device. If everything is configured right and still the communication does not work this may be due to problems with the send/receive-control. If the adapter does not release the transmitter quick enough, the answer of the HydroCal may be damaged and thus unrecognized. III. Modem The modem allows a remote connection using the phone network. From a communication point of view the connection via modem is very similar to the point-to-point connection via RS232. The connection supports full duplex, but may be limited in speed.
HydroCal
HydroSoft
The HydroCal modem configuration should have been carried as the device left the production. For HydroSoft select "Connect via:" - "Modem" and fill in the modem connection fields as described in the user manual, i.e. enter user name, password and phone number and select the modem to use for the communication. HYDROCAL 1002-1003: Manual for installation and operation
Page 46 of 97
B. RS485-Bus Using the RS485 interface it is possible to connect more the one HydroCal to a host. Nonetheless it is only possible to communicate with one device at a time. The illustration below shows the schematic topology. Remark: The host (PC) must only be present once (the host connected via the TCP/IP adapter is only present to show an alternate way to connect to the RS485 bus, as it is offered by third party network-to-serial bridges).

C. Bridge The (RS485-Bus-) bridge is an extension to access a range of HydroCal devices on a RS485 bus. In this setup the host (PC) is not directly connected to the RS485 bus but is using one of the HydroCal devices as communication gateway. The bridge functionality can be used for an RS232 or Modem primary connection as indicated by the illustration below.
The setup of all HydroCal devices must be according to a standard RS485 bus setup, with one exception. The HydroCal that shall serve as the communication gateway must be configured as a (bus-) bridge.

4.10.1. Alert Setup In the menu settings to alarms can be programmed by HydroSoft. Alarms can be triggered by internal sensors (H 2, CO, H2O, Oil temperature, temperature of sensor) or by external sensors (see chapter 4.11). The recommended temperatures for fault free operation of HYDROCAL 1002-1003. Temperature for sensors and oil below 30°C and over 60°C are generally not to expected and indicate a problem in the heating circuit. If temperatures are outside this range, then external (air) temperature and oil temperature must be considered. Lower sensor temperatures are possible during severe frosts or when transformers are switched off. Under certain circumstances temperatures higher than 60°C can exist with very hot oil in the transformer without being a problem of the heating circuit. In such a case, the measuring result can have additional error deviations. A total 16 alarms can be defined on the HYDROCAL 1002-1003 unit. If several alarms use the same output line, the status of alarms will be connected by an „OR“- statement, resulting to activate the corresponding output if an alarm is triggered. In the overview of alarms, (Alert Setup Overview) the following displays forms can be selected: •
Either List / View in form of a list
•
Or Details view (listing details of alarm settings)
•
Or Symbol view (presenting alarm settings as symbols)

or by „View->View As->...“
In the views „List“ and „Symbol“, the following dialogue can be opened by double clicking on one of the alarms (in view „Details“ it is not possible to open this dialogue):
First the mode of alarms must be selected under „Alert Mode“. Following modes are available: •
High: An alarm is triggered when Level 1 is exceeded.
•
High-High: An alarm in two steps is triggered. The 1 st alarm is triggered when Level 1 is exceeded; the 2nd alarm is triggered after exceeding Level 2.
•
Low: An alarm is triggered when a value falls below the limit defined in Level 1.
•
Low-Low: An alarm in two steps is triggered. Step 1 is alarm is triggered when the measured value falls below the limit defined in Level 1; the second alarm is triggered when the measured value falls below the limit defined in level 2.
HYDROCAL 1002-1003: Manual for installation and operation
Page 70 of 97
•
Low-high: An alarm in two steps is triggered. Step 1 is triggered when the measured value falls below the limit defined in Level 1; the second alarm is triggered after exceeding Level 2.
Range: An alarm is triggered when the measured value is outside the limits defined in Level 1 and Level 2. Once the alarm mode is set then, a sensor must be chosen. All above mentioned internal sensors are available. If external sensors are connected and configured, these can also be used (see chapter 4.11). The following measuring values are available: •
•
H2 Concentration
•
CO Concentration
•
H2 Daily trend
•
H2 Weekly trend
•
CO Daily trend
•
CO Weekly trend
•
Temperature 1
•
Temperature 2
All values defined under external sensors For a clear distinction of an alarm, under „Name“ a name can be inputted. The alarm levels are entered in the fields „Level 1“ and if necessary in „Level 2“. The units defined for concentration of gases „ppm”, for temperatures „°C” and for external sensors the unit defined for the respective sensor (e.g. Volt, Ampere ...) will be used. The alarm limits must be within the respective measuring ranges. This is 0..2000 ppm for gas concentration, 20..100°C for temperatures and for external sensors the maximum and minimum values of the sensor used. Delays1..2 can be introduced to suppress alarms during short-time exceeding of limits. Since the measuring cycle for gas sensors is 20 min, the delay time should not be less than 20 minutes.

5. RS232 / RS 485 Wiring This chapter contains information for the wiring of the connections. RS232 The connection via RS232 is done using the communication cable that is shipped together with the HydroCal device. This cable is designed to be directly plugged into a sub-D 9-pin male connector for an RS232 interface found on standard personal computers (or USB-to-serial adapters). RS485 The RS485 interface is implemented as a two-wire interface. The two signal wires must be clamped onto connector #7, pin 5.1 A(–) and pin 5.2 B(+) inside of the HydroCal. Care must be taken for the right polarity.
Termination, Biasing, Grounding and Protection of an RS485 Bus Termination, biasing, grounding and protection of an RS485 Bus is a complex thing and far beyond the scope of this document. A very good source of information related to these issues can be found at www.bb-elec.com (see the section Tech Notes ).

7. HYDROSOFT Scheduler 7.1 General Up to version 1.0.16 the transfer of the history data from the Hydrocal device into the Hydrosoft application could only be started manually. With version 1.0.18 an automatic read-out of the history data is possible. This is managed by the new scheduler integrated into Hydrosoft. In conjunction with the task scheduler provided by the Windows operating systems, the history data can be held up to date automatically.
7.2 Scheduler The scheduler is active in the background. It periodically checks all transformers for pending history data transfers. If an update is awaiting a connection to the Hydrocal is established and the history data read-out is executed. Remark: It is not possible to update the configuration, to reset alerts or to synchronize the real timer clock by the scheduler - these actions still must be carried out manually.
7.2.1 Configuring a Transformer for automatic History Data Update To configure the automatic history data read-out for a transformer, the connection scheduler dialog is used. To launch the dialog, the transformer main page must be activated by selecting the corresponding transformer in the tree view.
The dialog is accessible via the main menu (Transformer -> Scheduler...) or by clicking the rightmost button in the control area of the transformer window. 7.2.1.1 Connection Scheduler Dialog The connection scheduler dialog allow to configure the automatic history data read-out. (For further details on the setting see 0, 7.2.4 Internal Operation.)
HYDROCAL 1002-1003: Manual for installation and operation
Page 89 of 97
The checkbox Scheduled Data Read-Out en- or disables the automatic history data update. The combo box Connect Interval allows the selection of the time span between read-out actions. • After a successful history data update the next connection time is calculated by adding the selected interval time span to the current time. If the Connect Interval is at least one day, a connection time can be set in the text box Connect • Time . The format for the time is hh:mm:00 (seconds must be zero). When a connect time is set, the time-of-day for the next connection will be set to the specified value. If no special time-of day is required, a dash must be entered ('-'). • The Data Read Timeout has the same meaning as in the manual communication and defines a time when the connection has to be regarded as broken - leading to an error abort of the communication. For direct connections 5 seconds should be used - for a modem connection at least 15 seconds are reasonable. The text box Next Connect at shows the date and time of the next connection. • Remark: If a test of the scheduler communication is desired, a double-click on the text box will change the date and time so that the communication will be scheduled in the near future (dialog must be closed with OK to accept the change). The text box Connect Fail Count shows the number of connection failures. • Remark: A double-click on this text box can be used to reset the failure counter to zero (dialog must be closed with OK to accept the change). •
7.2.2 Scheduler Status Visualization The status of the scheduler is visualized in the tree view by changing the icons of the customer, the stations and the transformers. 7.2.2.1 Status Icons The status of transformers, stations and the customer is reflected by special icons. The following description explains the meaning of the different icons. 7.2.2.1.1 Transformer •
The standard icon is used for transformers that are not activated for scheduled history data update. • •
The read-out status is good. (The number of connection failures is less t han 3.) , The read-out status is bad. A connection has been tried several times but was not successful. The icon will be yellow (red) if the number of connection failures is greater then 2 (5).
•
A read-out is pending. The transformer has been marked for a communication and the history data update will be started in the near future. - This status overrules the good/bad-status. •
The transformer is currently busy in scheduler communication. The history data update is in progress. HYDROCAL 1002-1003: Manual for installation and operation
Page 90 of 97
•
The transformer is currently busy in a non-scheduler communication (manual connection or online sensor graph running). - This status overrules the good/bad/pending-status. 7.2.2.1.2 Station The station icon is derived from the status of the transformers that are members of the station and activated for scheduled history data update. •
If a station does not contain any transformer that is activated for scheduled history data update, it is shown with the standard icon. • •
The read-out status of all scheduled transformers of the station is good. , The read-out status of at least one scheduled transformer of the station is bad.
•
A read-out is pending for at least one transformer of the station. - This status overrules both the good/bad-status. •
A transformer in this station is currently busy in a scheduler communication. 7.2.2.1.3 Customer The customer icon is derived from the status of all transformers activated for scheduled history data update. •
The scheduler is active and idle. No communication is pending or active. •
The scheduler is active and waiting for the next pending communication to be started. •
A transformer is currently busy in a scheduler communication. 7.2.2.2 Example The following screen shots illustrate the scheduler operation. The scheduler is active (clock icon) and has scanned the transformers. The pending communications (Station1 and Transformer4 icon with clock) are marked. Station2 does not contain any scheduled transformers.
The scheduler has started the communication for Transformer1 in Station1 (all related icons indicate the active scheduler communication). The communication buttons in the transformer window control HYDROCAL 1002-1003: Manual for installation and operation
Page 91 of 97
area are disabled. The control area is shown with an alternate background colour to indicate the busy status.
The communication with Transformer1 in Station1 has failed more than 5 times. The transformer as well as the station are marked with failure indication icons (red station, red transformer).
7.2.3 Hydrosoft and the Windows Task Scheduler To fully automate the history data update, Hydrosoft can be regularly invoked via the task scheduler available in the Windows operating system. Windows provides a wizard to set up a task. Follow the instructions to create an entry for Hydrosoft. The timing setup for the Windows task depends on the personal needs and the setup of the scheduled history data update in Hydrosoft. If for example a daily update is configured in Hydrosoft the Windows task must also invoke Hydrosoft every day. After the entry has been created with the help of the wizard, the new command line options may be applied to tune the Hydrosoft task. Remark: Prior to setting up a Hydrosoft task it should be checked that the communication setup for the transformers is correct and it should be proved that the communication is working.

7.2.3.1.1 IdleClose The IdleClose command line option can be given to let the application terminate after all history data updates have be carried out. Following the command line option, a time span argument must be supplied, that defines the idle close time. The syntax for the close time is [hh:[mm:]]ss. When the Hydrosoft scheduler scans the transformers for pending history data updates, it determines the shortest time span, when the next communication has to be started. If this time span is greater than the idle close time, the application exits. When a daily update is configured a reasonable default for the idle close time is 15 minutes. This would allow for repeated communication tries (in case of failure), but exit, when the communication fails too often. 7.2.3.1.2 Minimized The Minimized command line option can be given to let the application start minimized. Remark: This option will also suppress the warning message, if the Hydorsoft data directory is in use by a manually started Hydrosoft application. A Windows task scheduler started instance of Hydrosoft can immediately exit, if a manually started Hydrosoft application is already running.
7.2.4 Internal Operation This is a more detailed description of the internal operation of the scheduler (the terms in italics are related to the data configured in the connection scheduler dialog). The scheduler runs as a separate thread in the background of Hydrosoft. Approximately every 15 seconds all transformers are checked if scheduled data read-out is active. Once a transformer is active, a further check is made, whether the current time is greater than the next connect at time. This way a list of pending connections is generated. If the list of pending connections is non empty, it is processed step by step, i.e. the list is traversed and all pending connection requests are executed before a new list is build. For each transformer a try to update the data is done. On success the connect fail count is set to zero and the next connect at time is updated (current time plus connect interval - optionally aligned to the connect time ). In case of an error the connect fail count is incremented and the next connect at time is set based on the current connect fail count . If the count is less than 3, a connection retry with 5 minutes delay is set, for a count less than 5 the retry is scheduled in 10 minutes. If the count exceeds 5, the next retry is scheduled to the current time plus the connect interval (- optionally aligned to the connect time , i.e. the same time as if the connection had succeeded). When the scheduler detects, that a time span of 3 times the connect interval has expired since the last start of the application, the connect fail count is reset to 4. This will lead to a double communication try for a transformer with a bad status when the application has not been used for a longer time period. Because of the internal operation the following notes apply: • •
Changes applied through the connection scheduler dialog take some time until they are reflected in the tree view. Even if the read-out status of a transformer is bad, there will always be a try to update the data with the configured connect interval . HYDROCAL 1002-1003: Manual for installation and operation

•
A manual update of the history data does not update the next connect at time of the scheduler. Even if an update occurs immediately before the next connect at time, the scheduled data readout will still be executed.
A log file 'Scheduler.log' is created in the root if the Hydrosoft data directory. If a problem arises with the scheduler a look into this file may help finding the cause. The log file entries are always written in English.
7.2.5. Data Directory Lock Hydrosoft now protects the data directory by a lock. Once an instance of Hydrosoft is working on a data directory no second instance of Hydrosoft can operate on the same data. This locking is introduced to keep data integrity in case a user is running Hydrosoft and a background instance of Hydrosoft (started via the Windows task scheduler) also tries to work on the data. Hydrosoft will exit with a return code of 2 if the data directory is locked.
