name programmed in setpoint User Input A Name, appears on the display with the Auxiliary LED and relay acti-
vated. Check in the Event Recorder that the selected function has been invoked.
16.3. Leave the monitored contact in the closed state and put the virtual input in the off state. Check that the diagnos-
tic message is removed from the display with the Auxiliary LED and relay deactivated.
16.4. Set the monitored contact to the open state and leave the virtual input in the off state. Check that the diagnostic
message appears on the display with the Auxiliary LED and relay activated.
16.5. Leave the monitored contact in the open state and put the virtual input in the on state. Check that the diagnostic
message is removed from the display with the Auxiliary LED and relay deactivated.
16.6. Repeat steps 16.3 through 16.7 for all functions programmed to be asserted by a Closed X Voff input.
17. For
INPUT ASSERTED LOGIC
17.1. Check that there is no logic input diagnostic message on the display.
17.2. Set the monitored contact for the logic input programmed in setpoint message User Input A Source to the open
state and the virtual input to the off state. Check that the diagnostic message, either User Input A or the name
programmed in setpoint User Input A Name, appears on the display with the Auxiliary LED and relay activated.
Check in the Event Recorder that the selected function has been invoked.
17.3. Leave the monitored contact in the open state and put the virtual input in the on state. Check that the diagnostic
message is removed from the display with the Auxiliary LED and relay deactivated.
17.4. Set the monitored contact to the closed state and leave the virtual input in the on state. Check that the diagnos-
tic message appears on the display with the Auxiliary LED and relay activated.
17.5. Leave the monitored contact in the closed state and put the virtual input in the off state. Check that the diagnos-
tic message is removed from the display with the Auxiliary LED and relay deactivated.
17.6. Repeat steps 17.3 through 17.7 for all functions programmed to be asserted by a Open X Von input.
18. For
INPUT ASSERTED LOGIC
18.1. Check that there is no logic input diagnostic message on the display.
18.2. Set the monitored contact for the logic input programmed in setpoint message User Input A Source to the open
state and the virtual input to the on state. Check that the diagnostic message, either User Input A or the name
programmed in setpoint User Input A Name, appears on the display with the Auxiliary LED and relay activated.
Check in the Event Recorder that the selected function has been invoked.
18.3. Leave the monitored contact in the open state and put the virtual input in the off state. Check that the diagnostic
message is removed from the display with the Auxiliary LED and relay deactivated.
18.4. Set the monitored contact to the closed state and leave the virtual input in the off state. Check that the diagnos-
tic message appears on the display with the Auxiliary LED and relay activated.
18.5. Leave the monitored contact in the closed state and put the virtual input in the on state. Check that the diagnos-
tic message is removed from the display with the Auxiliary LED and relay deactivated.
18.6. Repeat steps 18.3 through 18.7 for all functions programmed to be asserted by a Open X Voff input.

c) USER INPUT A FUNCTION SET TO "CONTROL"
The procedure to test this element is identical to that outlined for User Input A Function setpoint set to Alarm, with the fol-
lowing exceptions: there will not be any diagnostic message or Alarm LED.
d) USER INPUT A FUNCTION SET TO "TRIP"
The procedure to test this element is identical to that outlined for User Input A Function setpoint set to Alarm, with the fol-
lowing exceptions. The Trip Relay and LED will activate along with the Auxiliary Relay and LED. At the end of each test, a
reset must be performed in order to clear the trip diagnostic message and Trip LED.
Follow the Virtual On and Virtual Off Input Asserted Logic procedures outlined for Logic/Virtual Inputs 1 to 14 in the previ-
ous section.
