8.7 Diagnostics Menu
8.7.1 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. Sensors should
never be turned off unless directed to do so by Technical Support
Personnel.) 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 7 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 8 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.
8.7.2 4 –20 Test
4-20mA Test allows the user to send out discrete milliamp signals
from 4-20mA Output #1 and #2 to the control system. The 4-20mA
outputs are settable in one milliamp increments.
