time delay expires and verify that the bar graph indicator for Direct changes
color from green to yellow and that the Current Value Field indicates an
Alarm.
6. Press the RESET switch on the Rack Interface Module (RIM). Verify that the
bar graph indicator for Direct remains yellow and that the Current Value Field
still indicates an Alarm.
7. Adjust the power supply such that the signal just exceeds the Direct Over
Danger/Alarm 2 setpoint level. Wait for 2 or 3 seconds after the alarm time
delay expires and verify that the bar graph indicator for Direct changes color
from yellow to red and that the Current Value Field indicates an Alarm.
8. Press the RESET switch on the Rack Interface Module (RIM). Verify that the
bar graph indicator for Direct remains red and that the Current Value Field
still indicates an Alarm.
9. Adjust the power supply voltage such that the signal reads below the Over
Alarm setpoint levels. If the nonlatching option is configured, observe that
the bar graph indicator for Direct changes color to green and that the Current
Value Box contains no indication of alarms. Press the RESET switch on the
Rack Interface Module (RIM) to reset latching alarms.
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.
Gap
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 5.1.6.1
(Test Equipment and Software Setup - Thrust Position and Differential
Expansion).
3. Adjust the power supply to produce a voltage that is within the Gap setpoint
levels on the Gap bar graph display.
4. Press the RESET switch on the Rack Interface Module (RIM). Verify that the
OK LED is on, the bar graph indicator for Gap is green, and the Current
