If a low-pass filter is configured and no high-pass filter is configured, use HPF
= 3 Hz
If a high-pass filter is configured and no low-pass filter is configured, use LPF
= 5,500 Hz
Set the frequency of the function generator to this new value. The above is
done to obtain a test frequency in the center of the channel frequency range.
3. Adjust the function generator amplitude to produce a reading that is below
the Direct setpoint levels on the Direct bar graph display of the Verification
screen.
4. Press the RESET switch on the Rack Interface Module (RIM). Verify that the
OK LED is on, the bar graph indicator for Direct is green, and the Current
Value field contains no alarm indication.
5. Adjust the function generator amplitude such that the signal just exceeds the
Direct Over Alert/Alarm 1 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 green to yellow and 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 function generator amplitude 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 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 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. 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).
