Sensor Check
Selecting ‘Diagnostics>Sensor Check’ on the transmitter menu will
perform tests on all ‘ON’ sensors. (Individual sensors may be turned
off in the ‘Customize>Sensor Setup>State’ menu.) The test will take
several seconds to perform. After the test is completed, the screen
will display results.
The following are examples of test results.
Test Results: PASS
1:OK
2:OK
3:OK 4:OK
5:OK 6:OK
7:OK 8:OK
Figure 65 Test Passes Display Example
In the above figure the results indicate all sensors pass the test.
Test Results: FAIL: Continuity
1:SWITCH WT/BK
2:SWITCH WT/BK
3:OK 4:OK
5:OK 6:OK
7:DISCONNECTED 8:OK
Figure 66 Test Failed
In previous figure the sensor band failed the test. Sensor 1 and 2 are
either mis-wired between their terminals or reversed (wht to blk).
Sensor 7 is disconnected (open circuit).
If an error is noted when the sensor test is first run, repeat the test to
confirm the fault.
If the error occurs at first power up, verify wiring termination at the
transmitter terminal block. If a ‘disconnect’ error is seen after a
system has been in service, verify the sensor to transmitter cable is
not damaged or that a wire in the transmitter has not loosened from its
terminal block.

4–20 Test
Allows the user to send out discrete milliamp signals from 4-20mA
Output #1 and #2 to the control system settable in one milliamp
increments.
•
Gain
The sensor pre-amplifier is located within the sensor cover. The
electronic ‘Gain’ (amplification) applied to the sensor outputs can be
accessed through the transmitter ‘Diagnostics’ menu. Transmitter
