7PG2113/4/5/6 Solkor Description of Operation
Any BO can be assigned as a ‘Trip Contact’ in the OUTPUT CONFIG>TRIP CONFIG menu. Operation of a ‘Trip
Contact’ will operate any LED or virtual assigned from the trip triggered feature in the same menu and will initiate
the fault record storage, actuate the ‘Trip Alert’ screen where enabled and CB Fail protection when enabled.
The following notes refer to the binary outputs of the numeric module:
Notes on Pulsed Outputs
When operated, the output will reset after a user configurable time of up to 60 seconds regardless of the initiating
condition.
Notes on Self Reset Outputs
Self reset operation has a minimum reset time of 100ms
With a failed breaker condition the relay may remain operated until current flow is interrupted by an upstream
device. When the current is removed the relay will then reset and attempt to interrupt trip coil current flowing via
its output contact. Where this current level is above the break rating of the output contact an auxiliary relay with
heavy-duty contacts should be utilised in the primary system to avoid damage to the relay.
Notes on Hand Reset Outputs
Hand reset outputs can be reset by either pressing the
TEST/RESET
►
button, by energising a suitably
programmed binary input, or, by sending an appropriate command over the data communications channel(s).
On loss of the auxiliary supply hand-reset outputs will reset. When the auxiliary supply is re-established the binary
output will remain in the reset state unless the initiating condition is still present.
