7. Adjust the function generator amplitude such that the signal just exceeds the
1X Ampl Over Danger/Alarm 2 setpoint level. Wait for 2 to 3 seconds after
the alarm time delay expires and verify that the bar graph indicator for 1X
Ampl changes color from yellow to red and 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 1X Ampl remains red and that the Current Value Field
still indicates an Alarm.
9. Adjust the function generator amplitude such that the signal reads below the
Over Alarm setpoint levels. If the nonlatching option is configured, observe
that the bar graph indicator for 1X Ampl 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 function generator amplitude 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.
1X Phase
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 5.1.5.1
(Test Equipment and Software Setup - Radial Vibration).
Note
If you can not change the phase output, change the phase alarm setpoints to
activate the over and under phase alarms. The setpoints must be downloaded
to the monitor to take effect.
3. Set the Keyphasor multiplier/divider so that the multiply setting is one and the
divide setting is one. Adjust the phase to produce a reading that is within the
1X Phase setpoint levels on the 1X Phase bar graph display of the
Verification screen.
