SYMBOLS Special symbols are used in the manual to illustrate specifics in the step-by-step processes.
CAUTION 1. With some combinations of worst worst case high transducer scale factors and large full scale ranges, the 3300/20 Monitor may not reach a full scale reading before going not OK. For example, if the 7200 11mm transducer option is ordered with a full scale option of 2-0-2 mm or 75-0-75 mil (with or without barriers), worst case conditions could result in the reduction reduction of full scale by about 10%. Therefore, with this particular option, we recommend setting alarms at least 10% down from full scale. In all cases, verify that alarms can be reached with the actual transducer installation being used. 2.
With the 7200 11mm Transducer option and Internal or External Barriers, the green OK light will not go out if the transducer probe/cable opens, regardless of the full scale option.

3300/20 Dual Thrust Position Monitor Operation Manual
2. Monitor Functions DUAL THRUST POSITION - Thrust position is the average position, or change in position, of a rotor in the axial direction with respect to some fixed reference. The Dual Thrust Position Monitor provides continuous thrust position monitoring on two channels (A & B) for redundant protection. Normal thrust direction can be toward or away from the probe face. ‘AND’ voting logic ensures that failure of one channel will not give a false Danger alarm. ‘OR’ voting logic allows for two independent thrust channels in less critical applications. PROBE GAP VOLTAGE - Probe gap is measured as a negative dc voltage that is directly proportional to the gap distance between the face of a proximity probe and the surface being monitored. Probe gap voltage for each channel is displayed on the front panel meter by pressing the GAP switch. OK - When the proximity output voltage is within its upper/lower limits, the transducer is defined as OK. The OK detection circuit controls the channel OK LED and the monitor relay drive to the OK relay. If the monitor has the latching OK option, a System Reset is required to reset the OK function. OK RELAY - The OK Relay is located on the Power Input Module. Every channel in the rack must be OK or bypassed to energize the OK Relay. ALARM - Pressing the ALERT and DANGER switches on the front panel of the monitor causes the corresponding Alert (first-level alarm) or Danger (second-level alarm) setpoints on each channel to be displayed on the front panel meter. ALERT and DANGER LEDs light when the thrust position signal level exceeds preset levels for the selected time delay, and appropriate ALERT and DANGER alarm relay contacts are activated. Voting logic options determine when the Danger relay contacts are activated. FIRST OUT - Separate First Out circuits exist for Alert and Danger alarms. A monitor with First out option selected flashes a channel alarm LED if that monitor was the first channel in the rack to go into alarm. Pressing the RESET switch acknowledges the First Out. ALARM RELAYS - Monitor alarms can be programmed for either latching or non-latching mode. In the non-latching mode, the alarm resets automatically when the alarm condition no longer exists. In the latching mode, the alarm condition must be reset manually by pressing the RESET switch on the front panel of the System Monitor (or by closing external Reset contacts). The alarm will not reset if the alarm condition still exists. DANGER BYPASS - For maintenance functions, a DANGER BYPASS switch on the monitor circuit board is set to inhibit the Danger relay drive. This function turns on the BYPASS 2
Section 2 - Monitor Functions LEDs. Other front panel functions are not affected. This function can be disabled using a jumper within the monitor. BUFFERED OUTPUT - The channels A and B coaxial cable connectors on the front panel of the monitor and the terminals on the Signal Input Relay Module provide buffered signals from respective channel transducers. These connectors can be used for connection of external equipment. RECORDER OUTPUT - A recorder output is provided for each channel. Depending on the option selected, the recorder output levels, proportional to full scale, are 0 to -10 Vdc, +1 to +5 Vdc, or +4 to +20 mA. SELF TEST - The monitor has three categories of self test: cyclic, power-up, and userinvoked. •
Power-up self test is performed automatically each time the monitor power is turned on. A series of basic tests and transducer OK tests are performed.
•
Cyclic self test is performed automatically during monitor operation. Errors encountered during cyclic test disable the monitor, and flash an LCD bargraph error code. Should the error be intermittent, the monitor will return to operation, but the error codes are stored for retrieval during user-invoked self test. Stored error codes are indicated by the OK LEDs flashing at 5 Hz provided that the channel is OK.
•
User-invoked test performs power-up self test and allows error messages stored during cyclic test to be read and cleared. Stored errors are annunciated by the OK LEDs flashing a 5Hz and the error codes displayed on the front panel LCD bargraph.
SIGNAL RESPONSE TIME To reduce the chance of alarms caused by axial vibration and shaft runout, the Signal Conditioning performs a running average of the shaft position. This average causes step changes in axial vibration to be integrated over time. The time constant changes according to the alarm time delay as shown in Table 1. METER RESPONSE The meter response time can be selected to be fast or slow. With a fast response, the meter will follow the signal conditioning exactly as seen by the monitor. In installations where there is a large AC component of the thrust signal, this will cause apparent meter jitter. Selecting the slow meter response reduces the meter's response to rapidly changing signals, but does not affect the monitor's Recorder or Alarm circuits.

14.2 Test the Danger Setpoint Level 1. Adjust the power supply voltage past the Danger Setpoint level in the Normal direction and verify that the DANGER LED comes on (flashing if the First Out Option is selected). 2. Verify that the Danger Relay changed state. If Danger ‘AND’ Voting logic is selected, the relay will not change state until the other channel exceeds the Danger Setpoint (unless the other channel is Not OK or bypassed). 3. Danger ‘AND’ Voting is not active if the second channel is bypassed. If one channel is bypassed, a signal level exceeding the Danger Setpoint level on the nonbypassed channel will cause the Danger Relay to change state. The Danger Bypass switch being on will inhibit the relay from changing state.
4. Press the RESET switch on the System Monitor. 5. Verify that the ALERT and DANGER LEDs remain on and steady. 6. Repeat the Alert and Danger Setpoint Level tests for the Counter direction.

15. Test OK Limits Caution High voltage present. Contact could cause shock, burns, or death. Do not touch exposed wires or terminals.
Tests will exceed alarm setpoint levels causing alarms to activate. This could result in relay contacts changing state. See Danger Bypass, Section 12.
Before bringing the monitor on line, use this procedure to check that the OK Limits for channels A and B are working properly. You will need equipment as described in the Test Setup section. 1. Adjust the gap voltage for approximately -9.0 Vdc with respect to common and verify the OK LED is on for the channel being tested. Press RESET on the system monitor to turn on the OK LED if the latching OK mode is installed. Note: All other channels in the rack must be OK or bypassed in order for the relay to change states.

Section 16 - Calibrate Channels
16. Calibrate Channels
High voltage present. Contact could cause shock, burns, or death. Do not touch exposed wires or terminals.
16.1 Calibration Procedure Before you begin Channel Calibration, you must choose the full scale range and set the appropriate jumpers (See Section 19). You will need equipment as described in the Test Setup, section 13. (Repeat for channels A and B.) 1. Slide front panel to right and adjust the input signal voltage at the SIRM to obtain a voltage of +2.5 Vdc at the Channel A test point (BPPLA). Measure and record the input voltage. This value will be the zero voltage used in step 3.
33
3300/20 Dual Thrust Position Monitor Operation Manual 2. Verify that monitor display indicates 0 mil (0mm). 3. Change the input voltage for full scale value. •
1 mil = 200 mV
1 mm = 7.87 Vdc For systems with external barriers, use: •
• •
1 mil = 192 mV 1 mm = 7.56 V
For example: The scale factor is 200 mV/MIL for 40 - 0 - 40 mil range, with 5 mm probe, and without barriers. Full scale voltage change would be: 40x200 mV/MIL = 8.000 Vdc. •
If Normal direction is toward the probe, the full scale value is the zero voltage minus the full scale voltage. For example, with a zero voltage (from step 1) of -10.00 Vdc the full scale value is: (-10.000) - (-8.000) = -2.000 Vdc input.
•
If Normal direction is away from the probe, the full scale value is the zero voltage plus the full scale voltage. For example, with a zero voltage (from step 1) of -10.00 Vdc the full scale value is: (-10.000) + (-8.000) = -18.000 Vdc input. NOTE: See Section 16.2, Zero Voltage Adjust, for the zeroing voltage appropriate for your transducer.
4. For Normal direction - Adjust potentiometer (GA) for +5.00 Vdc on Channel A test point. For Counter direction - Adjust potentiometer (GA) for 0.0 Vdc on Channel A test point. Verify that the front panel indicates full scale and that the recorder output matches the option selected.
34
Section 16 - Calibrate Channels
16.2 Zero Voltage Adjust NOTE:
The monitor expects a specific gap voltage when the rotor is at its zero position. The type of transducer being used determines this voltage. In the following procedure, the probe gap is adjusted so that the appropriate voltage is output by the probe when the rotor is at its zero position.
1.
Ensure that rotor is set to the desired zero position (against active or inactive bearing, or center of float zone).
2.
Connect a multimeter to IN and COM terminals on the monitor Signal Input Module as shown below.
2.
Adjust probe gap for zeroing voltage specified below for the transducer type installed.

35
3300/20 Dual Thrust Position Monitor Operation Manual 3.
Slide the front panel of the monitor to the right and connect a multimeter to Channel A test point BPPLA. Adjust Channel A zero potentiometer (ZA) for +2.500 Vdc. The monitor bargraph should display zero.
NOTE:
If the monitor will not zero and re-gapping the probe is not practical, the zero adjust range can be increased by changing the jumpers listed in the following tables. If the zero adjustment range is increased, it is important to verify that the OK voltage level check recognizes Not OK conditions. After selecting the new zeroing range and calibrating the monitor, verify that the OK LEDs go out when the shaft is at either of its extreme limits. If the OK LEDs do not go out, the system must be recalibrated and the OK limits checked again until this requirement is met.

16.3 Prepare to Bring the Monitor On Line (Repeat for channels A and B) 1.
Reduce the input amplitude to below the alarm setpoints and observe that the ALERT and DANGER LEDs go off (if non-latching alarm jumpers are installed).
2.
Press the RESET switch on the System Monitor to reset latching alarms.
3.
Disconnect the test equipment and reconnect the transducers to their respective channels in accordance with the field wiring diagrams at the end of this manual. Verify that the OK LEDs come on and the OK Relay energizes (if non-latching OK mode is selected).
4.
Press the RESET switch on the System Monitor to reset latching not OKs.
5.
If the Channel Bypass or the Danger Bypass functions were activated for this procedure, deactivate them before monitoring resumes (see Sections 11 & 12 of this manual).
6.
Close the front panel.
38
Section 17 - Self Test
17. Self Test The monitor has three levels of self tests: SELF TEST PERFORMED Power-up When the monitor is turned on. Continuous during monitoring Cyclic operations. When you initiate the self test by User-invoked temporarily shorting the self-test pins. When the monitor detects an error, it displays an error condition two ways depending on whether the error is active or stored. An active error is an error that currently exists. A stored error condition results from a storable error momentarily occurring after the last time all errors were cleared.
Active Error Indication
If the monitor detects an active error, the following events occur: • Monitoring stops until the problem is resolved • The error code is stored in memory and flashes on the LCD bargraph • The BYPASS LEDs come on • The OK LEDs flash at 5 Hz • The OK Relay de-energizes Active errors that do not flash the OK LEDs require userinvoked self test or may require recycling power to clear them. If either of these actions fails to clear the error refer to the Error Codes section. If the monitor no longer detects an active error and a stored error exists, the following events occur: •
Monitoring resumes
•
If the OK LED would otherwise be on, the OK LEDs flash at 5 Hz to indicate that an error code has been stored If all other channels in the rack are OK, the OK relay will energize if non-latching OK mode is set. Press RESET on the system monitor to restore the OK relay condition for the latching mode.
•
Stored Error Indication
39
3300/20 Dual Thrust Position Monitor Operation Manual Recall stored error codes by using the User-invoked self test. Use the following steps to run the User-invoked self test, read error codes, and clear stored error codes:
Caution Machine protection provided by this monitor will be lost for the duration of the self test. Note: If any error is active, a Userinvoked self test cannot be initiated. Refer to the error Codes Section. 1. Initiate the User-invoked self test by shorting the two self test pins ( ST) with a screwdriver. All the LEDs and LCD elements will come on for 5 seconds. The OK relay will de-energize during this test. If an active or stored error is present at the end of the self test, the BYPASS LED remains on, the OK LEDs flash at 5 Hz, and the first error code flashes at 2 Hz on the LCD bargraph. The error code is given by the number of flashing segments in one column of the bargraph. For example, the monitor to the right is indicating error code number 6
40
Section 17 - Self Test
2.
Read any other stored error codes by pressing and holding the ALERT switch for approximately one second. For example, the display to the far right contains a second stored error code - number 10.
4.
When you reach the end of the error code list, the LCD bargraph comes on with all LCD segments lit and the OK LEDs turned off. You may read through the list again by continuing to press the ALERT switch.
