In the desktop version, the parts 1 and 2 are assembled into a unique case. 2: The quantities listed for the positions from 3 to 6 are referred to the 2 Temperature, 2 EMC, 6 Timber MC probes version.

Installation tips For a proper installation of the controller it is necessary to follow some precautions:   The central unit with screen and keyboard and the relay outputs unit must  be placed into a room having temperature between b etween 0 and 40C.   If «NOME_PRODOTTO» controller (panel version) is installed on a switchboard, it is necessary to pay particular attention to the correct assemblage of the other equipments installed inside the same switchboard, installing, where suggested, all the filters required to reduce the interferences. Especially if a frequency inverter for fans driving is present , it is necessary to follow all the indications of the manufacturer to avoid the - 14 -

 

kiln dryers controller «NOME_PRODOTTO» – r.«REVISIONE»

generation of interferences that could affect the operation of the control con trol system.   The probes amplifier amplifier must be installed close to the kiln, to maintain the connection cables to the probes boxes as short as possible. Although the LG25 amplifier is furnished in watertight case, it is absolutely advisable to avoid its direct exposure to the rain: a minimum protection constituted  by a simple plate roof should be always provided. The temperature and EMC sensors must be positioned inside the kiln so that to assure a representative measure of the climatic conditions inside it. If the kiln is equipped with reversible fans, the sensors must be placed on  both the sides of the kiln; if the front side is completely occupied by the loading door, the sensor should be positioned on the side wall, close to the door.   The cables for probes box connection and for wood moisture measurement have to be under good conditions. No junction or reparation is admitted, because it could affect the cable insulation characteristic. In the case of insufficient length, it is necessary to replace the whole cable. This

 

 

limitation the other of be connection the controller. The probesdoesn't boxes concern connection cablescables have to placed atof30cm minimum from whatever other power cable.

The distance among CPU unit, the power unit and the probes amplifier, can be also very high (< 1,2Km), because the communication among these devices is made through an RS485 line, suitable suitable for long distances. In case of long distances (>100m) or of environments particularly disturbed, it could be necessary to use special cables, especially developed for RS485 transmission; in this case the power supply must be conducted separately, using another cable.

Connections

«NOME_PRODOTTO» CPU (LG28) – LG39 «NOME_PRODOTTO» The LG39 is the new input/output unit which may be supplied instead of the LG29 as standard equipment of the control system.

The control panel of the kiln controller must be connected to one of the two KilnBus connectors (CN2 or CN3 - they are internally connected) of the input/output LG39 unit, using the supplied cable (connection 1:1*). The other connector (CN3 or CN2) can be used to connect the next devices on the  bus. (*) Please note that, although the pins number is reversed if compared to the control panel, the functions are on the same pin (1:1 connection).

Dip-switch settings The LG39 is equipped with 8 configuration dip-switches. Use a small sharpen tool to place them. The following table summarizes the function of the dip-switches (Off=0, On=1):

When the “Safe mode” is enabled, after 4 minutes of inactivity of the serial inte r-

face, all the outputs will be disabled, but the HEATER CLOSE and the FLAPS CLOSE will be activated, in order to set the kiln under a safe condition. When this alarm condition occurs, the DATA ERROR led flashes every second. Under normal conditions, for use with standard controllers, the switches should remain as showed in the “Factory settings” row.   Whatever change on the dip-switches setting will be effective only after a reset of the device.

Inputs / Outputs Outputs description The power supply input and the relay outputs are available on the CN4 and CN7 connectors. The power supply for the whole system must be applied to the pins 1 and 2 of the CN4 connector; these contacts are internally connected to the KILN-BUS plugs through the FUSE 1 (5A) protection, to supply all the peripheral devices. All the common contacts of the relays are connected to the same input (CN7 - 8) that can be connected to whatever voltage from 0 to 250Vac. A protection fuse (FUSE 2.5x20mm  –   5A) is connected in series to this input; the sum of all the loads consumption must not exceed the fuse maximum current rating.

LG35 Probe amplifiers The multi sensor sensor LG35 includes all the sensors required for the Kilns management and the electronic to transform the signals in digital information. It should be installed inside the kiln in a position suitable to measure the average climate conditions of the cell. WARNING: LG35 cannot be exposed directly to water spray and to tem peratures higher than 80°C, otherwise other wise serious damage may occur. occur . LG35 is equipped with a new, spring cage type connector, for an easy and faster wiring. To access the connector, unscrew the four screws of the front panel. Remove the front panel CAREFULLY, and temporary fix it at the left side (see  picture) while wiring the connector, in order to avoid any stress to the delicate connections between the front panel and the connection board..

Connect the kiln bus cable to the connector. Two inputs are provided for an easy chain connection: the kiln-bus can be connected to one of the two inputs, while the other is available to connect the next device (if any). For the connection use the following wires:

On the main connector there is also the measuring circuit ground , which is sup plied connected to the metallic roof of LG35 through a capacitor. cap acitor. The metallic roof should be connected to an earth connection, not shared with other power devices. To get good performances, in most of the applications, it is enough to install LG35 on the metallic walls of the kiln. The missing or insufficient earth connection may cause problems in measuring very low EMC and MC values. If this kind of problem is encountered, the following solutions should be tested: - 25 -

 

1)  Disconnect the capacitor from the LG35 metallic roof and connect it to a ”clean” (addicted only to the measuring circuit) earth connection.   2)  Leave the “Meas. GND” input of LG35 unconnected.  3)  Connect the Meas.GND pin directly to a clean earth connection. (Warning: this solution could carry to errors in measuring very high timber moisture contents) Observing the the rear side of the ffront ront panel a dip-switch wit 8 positions can be found. For this application their position should be: 8,6: ON, all the others OFF. Usually they are set in factory so there is no need to adjust them.

Looking obliquely into the dip-switch window two LEDS can be seen. In normal operation only the green LED should blink approx. once a second; the red led  blinks at power on or in case of communication co mmunication problems. At the end of the wiring, wiring, before closing the cover, be sure that no wire is is positioned over the connector, because there is no room available between the connector itself and the rear side of the cover. Pay also atte attention ntion to the proper positioning of the sealing gasket.

Configuring «NOME_PRODOTTO» After having installed and connected the controller, before being able to use «NOME_PRODOTTO», «NOME_PRODOTT O», it is necessary to proceed with it itss configuration, to suit it for the characteristics of the specific kiln. The configuration is effected through the addicted “Service only menu.”. Under this menu are grouped all the settings that must normally be set during the controller installation and that hardly will be modified later, during the normal use of the kiln. Following there is a list of the settable parameters for every submenu, together with a description of the meaning for each one.

Menu Service Preferences They are a series of settings related to the management of the drying cycle.

Close flaps if temp. falls It set the priority for conditions theallows flaps to should bemanagement open if the humidity in the the dampers. cell is tooUnder high.normal With particularly cold climate and/or with under dimensioned heating systems, the opening of the flaps could also cause an unwanted diminution of the temperature in the cell. To avoid this, it is possible to set this value on a value different from 0°C. In this way the temperature in the cell has higher priority than the humidity and, if it falls below the ideal values minus this setting (in °C), the flaps are closed, regardless to the moisture in the cell, until the temperature reaches again its ideal value. If this function is not required, set this value to 0°C to exclude it. Default setting: 5°C

Sprayers - Flaps enabling temperatur temperature e It is the minimum temperature below which the sprayers and the flaps are forced closed (disabled). Default setting:: 20C High temp. alarm delay It is the delay, in minutes, from the identification of an alarm condition for high temperature (10°C higher in comparison to the set-point) and its signalling. Default setting: 20 EMC alarm delay It is the delay, in minutes, from the identification of an EMC alarm condition (+/5,0 in comparison to the set-point) and its signalling. Default setting: 20’  Save measures every: «NOME_PRODOTTO» can preserve a trace of the last 80 effected measures into its memory, included the correspondents ideal values and the state of the timber  probes. This parameter allo allows ws to set the iinterval nterval in hours among two following re re-cordings. Default setting : 8h Cooling phase mode It specifies how the cooling have to be performed. When there is a cooling demand (usually at the end of the cycle) the controller can proceed in two ways: Natural: the heating is turned off, and all the other functions (flaps, sprayers) continue to work in normal the heating is way. turned off and the flaps are opened.  In case of too low Forced: EMC, the sprinklers are also activated;. Only if an alarm for too low EMC occurs, the flaps are closed again, up to the end of the alarm condition. Default setting: Natural

EMC compensation Use this function for fine adjustments on the measures of EMC effected by the controller. The correction of the EMC measure is especially useful when cellulose  plates different from those furnished with the equipment eq uipment or plates made from fro m other materials are used as sensors. The compensation is limited to +/-3,0; the set value is added to the measure detected by the controller.

Default setting: 0.0 - 31 -

 

Timber MC / EMC / Temperature calculatio calculation n mode They are referred to timber probes, temperature probes and moisture probes and are used to specify how the measures received from the various sensors must be managed. For all the types of probes, you can specify whether the regulation value should be the highest value, at the lowest value or at an arithmetic average of the measured values. The controller is preset to regulate on basis of the average timber moisture and of highest temperature and the lowest EMC measured in the cell (usually the most critical values of all). In some cases, it can be useful to adjust the cycle according to other values; for ex, when the timber is particularly subject to mould stains, an adjustment based on the highest EMC value can be more suitable or in case of timber that requires a minimum temperature to ensure an adequate treatment against parasites, it may be better to adjust the temperature at its lowest value High temperature alarm threshold. Defines the difference between measured and ideal temperatures which enables the countdown for high temperature alarm signalling. Default setting: 10,0 EMC alarm threshold Defines the difference between measured and ideal EMC which enables the countdown for high/low humidity alarm signalling. Default setting: 5,0

Phase timer mode Specifies how to manage the timing of the drying phases, If set to “T_OK” the

countdown begins the temperature required forwhen the phase has been reached. If set to “Start” thewhen countdown begins immediately the phase is started, r ee-gardless of temperature.  NOTE: when the timer for a ddrying rying phase is set to 0 or the phase is marked as HT  phase, the controller will wait for the required temperature before starting the countdown, regardless of the setting of this parameter. Default Setting: “T_OK” 

Variation EMC/hour Defines the hourly variation allowed for the EMC set. If the measured EMC is different by the set EMC required by the program, the required value will be reached according to the specified speed. - 32 -

Flaps On/Off activation threshold. This parameter is considered only when Flaps management is set to ON/OFF mode, and specifies the threshold above set point for opening the flaps. The flaps will remain opened until the EMC value return to the ideal value. Default setting: 1,2 Flaps at end of cycle Defines whether the flaps should be ON (opened) or OFF (closed) when the cycle has been completed. (end of cycle). Default setting: OFF MC compensation This parameter can be used for fine adjustments on the measures of Timber Moisture performed by the controller, in order to match it with the preferred reference meter of the user.

Condensation based kiln By setting this parameter to “1”, the controller will be configured to manage a condensation kiln (a special drying kiln that uses a dehumidifier system to decrease the air humidity, instead of requiring fresh air from outside like the conventional kilns do). For the condensation kilns, the relay normally used for the flaps is used to drive the refrigerator, and the relay normally used to signal an alarm becomes the overheating relay. These relays are managed as follows: Refrigerator (flaps): Overheating (alarm):

disabled for temperatures below 30C ON when EMC>Set-point +0.8 OFF when EMC Set-point +3.0C OFF when when Temperature
