Inputs/Outputs
a) Actual Values Display
For these first tests, the
INPUT 1 (14) ASSERTED LOGIC
as "Closed | Von". Under the
subheading,
1. Turn on this input and check that the display shows this state.
2. Turn off this input and check that the display shows this state.
Under the
A1 STATUS HARDWARE INPUTS
1. Close the contact connected to this input and check that the display shows this
state.
2. Open the contact connected to this input and check that the display shows this
state.
b) User Input A Setpoint set to "Alarm"
1. Set all inputs 1 through 14, both contact and virtual, to the de-asserted state.
2. Enter (example) settings under subheading
: "User Input A"
USER INPUT A NAME
: "Input 1"
USER INPUT A SOURCE
: "Alarm"
USER INPUT A FUNCTION
USER INPUT A RELAYS (3-7)
: "0.00 s"
USER INPUT A DELAY
3. For
INPUT ASSERTED LOGIC
3.1. Check that there is no logic input diagnostic message on the display.
3.2. Set the monitored contact for the logic input programmed in setpoint
USER INPUT A SOURCE
tual input will have no affect.
3.3. Check that the diagnostic message, either User Input A or the name pro-
grammed 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.
3.4. Set the monitored contact for the logic input programmed in setpoint
USER INPUT A SOURCE
virtual input will have no affect.
3.5. Check that the diagnostic message is removed from the display with the
Auxiliary LED and relay deactivated.
3.6. Repeat Steps 3.1 through 3.5 for all functions programmed to be
asserted by a Contact Close input.
4. For
INPUT ASSERTED LOGIC
4.1. Check that there is no logic input diagnostic message on the display.
4.2. Set the monitored contact for the logic input programmed in the
setpoint to the open state. Note that the corresponding
INPUT A SOURCE
virtual input will have no affect.
4.3. Check that the diagnostic message, either User Input A or the name pro-
grammed 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.
4.4. Set the monitored contact for the logic input programmed in setpoint
User Input A Source to the closed state. Again note that the correspond-
ing virtual input will have no affect.
4.5. Check that the diagnostic message is removed from the display with the
Auxiliary LED and relay deactivated.
