Generator Closed Auxiliary
IEEE 37.2 - 3 Checking or
interlocking relay
This input is used to provide feedback to allow the DSE7400 to give
true indication of the contactor or circuit breaker switching status. It
should be connected to the generator load switching device auxiliary
contact.
Action:
Warning (Alarm only, No shutdown)
Generator Load Inhibit
IEEE 37.2 - 52 AC circuit breaker
This input is used to prevent the DSE7410/DSE7420 from loading the
generator. If the generator is already on load, activating this input will
cause the DSE7410/DSE7420 to unload the generator. Removing the
input will allow the generator to be loaded again.
NOTE: -This input only operates to control the generator-
switching device if the DSE7410/DSE7420 load switching logic is
attempting to load the generator. It will not control the generator-
switching device when the mains supply is on load.
Inhibit Retransfer To Mains
IEEE 37.2 - 3 checking or
interlocking relay
When active, this input prevents the load being transferred back to the
mains supply, even in the event of the generators failing.
Inhibit Scheduled Run
IEEE 37.2 - 3 checking or
interlocking relay
This input is used to provide a means of disabling a scheduled run.
Lamp Test This input is used to provide a test facility for the front panel indicators
fitted to the DSE8600 module. When the input is activated all LED’s
should illuminate.
Low Fuel Level Switch A digital normally open or closed fuel level switch gives this input. It
allows fuel level detection using the switch and the analogue input to be
used in parallel to give protection or to be used for fuel level indication
only.
Main Config Select This input is used to select the
configuration when
configurations are enabled.
Mains closed Auxiliary
IEEE 37.2 - 3 Checking or
interlocking relay
This input is used to provide feedback to allow the module to give true
indication of the contactor or circuit breaker switching status. It should
be connected to the mains load switching device auxiliary contact.
Incorrect application of this signal does not trigger an alarm condition, it
is used solely for indication of the breaker status.
Mains Load Inhibit
IEEE 37.2 - 3 checking or
interlocking relay
This input is used to prevent the from loading the mains supply. If the
mains supply is already on load activating this input will cause the
module to unload the mains supply. Removing the input will allow the
mains to be loaded again.
NOTE: -This input only operates to control the mains
switching device if the DSE7400 load switching logic is attempting
to load the mains. It will not control the mains switching device
when the generator is on load.
