10. Repeat steps 3 through 9 to test the Under Alert/Alarm 1 and Under
Danger/Alarm 2 setpoints by adjusting the power supply to exceed the Under
Alarm setpoint levels.
11. If you can not verify any configured alarm, recheck the configured setpoints.
If the monitor still does not alarm properly or fails any other part of this test,
go to Section 5.1.11 (If a Channel Fails a Verification Test).
12. Disconnect the test equipment and reconnect the PWR, COM, and SIG field
wiring to the channel terminals on the I/O module. Verify that the OK LED
comes on and the OK relay energizes. Press the RESET switch on the Rack
Interface Module (RIM) to reset the OK LED.
13. Repeat steps 1 through 12 for all configured channels.
5.1.7.3
Verify Channel Values - Eccentricity
The general approach for testing these parameters is to simulate the eccentricity
signal with a function generator and power supply. The output levels are verified
by varying the output from the test equipment and observing that the correct
results are reported in the Verification screen on the test computer.
Peak to Peak
1. Disconnect PWR, COM, and SIG field wiring from the channel terminals on
the I/O module.
2. Connect test equipment and run software as described in section 5.1.7.1
(Test Equipment and Software Setup - Eccentricity).
3. Calculate the full-scale voltage according to the following equation and
examples.
