•
“OFF” is displayed if the Relay Set Up (P100) selected does not use the Alarm
parameter accessed.

Custom Relays (P110 to P113)
P110 Relay Allocation
Use this feature to alter the Relay Set Up (P100) relay/ point number association,
to have any relay operate based upon the operation of any Point Number.
When accessed, the Relay symbol is displayed in the Point Type field and the
Relay Number (corresponding to the DPS300 terminals) is displayed in the Point
Number field.
e.g.
To allocate Relay 3 to Point 1, with Relay Number 3 displayed, enter 1.
If a relay is allocated to more than one Point Number, when any Point Number (in
the allocation range) is in alarm, the relay de-energizes.
Note:
When Relay Allocation is altered, affected alarm (P101 to P104) parameters
display “ch” (changed), when accessed. Use the Relay A/B Setpoint (P112/P113)
instead.
Values:
x (x = single Point Number (1-3) to be allocated to the displayed Relay
Number)
x.y (x = first Point Number (1-3), y = last Point Number (1-3), in the range)
P111 Relay Function
Use this feature if alternate relay function, designation, or operation is required.
When accessed, the Parameter Type display changes to the Relay symbol and
the Point Number display changes to the Relay Number (corresponding to the
DPS300 terminals).
