Manual Control of Powermonitor Relays
6–3
An operate operation causes normally open contacts (RX4 / RX1)
to close, and normally closed contacts (RX1 / RX2) to open.
A pulse operation will cause normally open contacts (RX4 / RX1)
to close, and normally closed contacts (RX1 / RX2) to open for a
duration specified by the VALUE parameter for the device, after
which the relay will return to its previous state.
This command will override the setpoint control functions.
c. 3 – FORCED OFF. This operation will cause the indicated relay
number to release if the relay is in latch mode. This causes
normally open contacts (RX4 / RX1) to open, and normally closed
contacts (RX1 / RX2) to close.
This command has no effect if the relay is in pulse mode.
This command also overrides the setpoint control functions.
After the type of relay operation has been selected, the operator is prompted
with:
CONFIRMING OPERATION OF RELAY (Y/N)?
This provides an added level of security by forcing the operator to confirm
the intention to execute the command.
If “Y” is selected, the Powermonitor responds to the Powermonitor Software
with the outcome of the operation. A relay successfully operated or released
manually by the operator will be shown as having been FORCED ON or
FORCED OFF. If control is returned to the Powermonitor, the relay status
will be shown as either ON or OFF.
If “N” is selected, Powermonitor Software will display the message:
RELAY OPERATION ABORTED
!
ATTENTION: 1) Manual operation or release of a relay
overrides the normal setpoint operation of that relay.
2) In the event of a power interruption to the device, all relays
revert to the normal state, with all setpoint functions re–enabled.
