6. Set the monitored contact for the logic input programmed in setpoint
USER INPUT A SOURCE
to the closed
state. Again note that the corresponding virtual input will have no affect.
7. Check that the diagnostic message is removed from the display with the 3 auxiliary LED and relay deacti-
vated.
8. Repeat steps 3 through 7 for all functions programmed to be asserted by a
Contact Open input.
For
INPUT ASSERTED LOGIC
setpoints set to Virtual On
1.
2.
3. Check that there is no logic input diagnostic message on the display.
4. Set the monitored virtual input for the logic input programmed in setpoint message
USER INPUT A SOURCE
to
the on state. Note that the corresponding contact input will have no affect.
5. 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 3 auxiliary LED and relay activated. Check in the Event Recorder
that the selected function has been invoked.
6. Set the virtual input for the logic input programmed in setpoint message
USER INPUT A SOURCE
to the off
state. Again note that the corresponding contact input will have no affect.
7. Check that the diagnostic message is removed from the display with the 3 auxiliary LED and relay deacti-
vated.
8. Repeat steps 3 through 7 for all functions programmed to be asserted by a
Virtual On input.
For
INPUT ASSERTED LOGIC
setpoints set to Virtual Off :
1.
2.
3. Check that there is no logic input diagnostic message on the display.
4. Set the monitored virtual input for the logic input programmed in setpoint message
USER INPUT A SOURCE
to
the off state. Note that the corresponding contact input will have no affect.
5. 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 3 auxiliary LED and relay activated. Check in the Event Recorder
that the selected function has been invoked.
6. Set the virtual input for the logic input programmed in setpoint message
USER INPUT A SOURCE
to the on
state. Again note that the corresponding contact input will have no affect.
7. Check that the diagnostic message is removed from the display with the 3 auxiliary LED and relay deacti-
vated.
8. Repeat steps 3 through 7 for all functions programmed to be asserted by a
Virtual Off input.
For
INPUT ASSERTED LOGIC
setpoints set to Closed & V
on
:
1.
2.
3. Check that there is no logic input diagnostic message on the display.
4. 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 no diagnostic message is on the display with the
3 auxiliary LED and relay deactivated.
5. Set the monitored contact to the closed state with the virtual input remaining in the off state. Check that no
diagnostic message is on the display with the 3 auxiliary LED and relay deactivated.
6. Leave the monitored contact in the closed state and put the virtual input in 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 3 auxiliary LED and relay activated. Check in the Event Recorder that the selected
function has been invoked.
