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.
Direct
Note
The Keyphasor must be triggering and have a valid rpm value to check this
parameter.
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. Adjust the power supply to produce a reading that is within 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 has no alarm indication.
5. Adjust the power supply voltage 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 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.
