3.6 OUTPUTS
Ten (10) digital outputs are fitted to the DSE8610 controller. Additional outputs are provided for by
adding up to ten (10) external relay boards (DSE2157). This allows for up to 80 additional digital
outputs.
3.6.1 OUTPUTS A & B
Type
Normally used for Fuel / Start outputs. Fully configurable for other purposes if the module is
configured to control an electronic engine. Supplied from Emergency Stop terminal 3.
Rating 15A resistive @ 35V
3.6.2 OUTPUTS C & D
Type
Voltage free relays, fully configurable, normally used for generator / mains load switch
control.
Rating 8A resistive @ 250 V AC
3.6.2.1 CONTACTOR COILS
Use output D, the normally open relay:
3.6.2.2 UNDERVOLTAGE (UV COILS)
Use output C, the normally closed relay :
Generator
DSE output drives the contactor coil, via external slave relay if required.
When the DSE module requires the contactor closed, the output energises (closing the internal
relay)
When the DSE module requires the contactor to be open, the output is de-energised (opening
the internal relay)
Generator
DSE output drives the UV coil, via external slave relay if required.
When the generator starts, the UV is powered via the normally closed relay. The breaker is
now ready for the close signal to be given. When the breaker is to be opened, the Open
Generator Pulse relay is operated, removing power from the UV coil for one second. This
causes the breaker to trip (open) as the UV is no longer powered. The Open Generator
Pulse relay switches back to its closed state, ready to power the UV coil the next time the
generator starts.
