Bus Live
This output indicates that a voltage has been detected on the bus. Once the
voltage on the bus is detected above the “Dead bus relay setting”, it will no
longer be considered a ‘dead-bus’ and the generator will need to synchronise
in order to get onto the bus.
Bus Not Live Alarm
This output indicates that the generator bus remains ‘dead’ after closing the
generator load breaker.
Bus Phase Rotation Alarm This output indicates that the module has detected a phase sequence error on
the bus.
Bus Not Live Active when Generator breaker closes and the bus is not seen to go live.
Calling For Scheduled Run
Active during a scheduled run request from the inbuilt scheduler.
CAN ECU Data Fail Becomes active when no CAN data is
received from the ECU after the safety
delay timer has expired
Inactive when:
• CAN data is being received
• The set is at rest
• During the starting sequence
before the safety delay timer
has expired
CAN ECU Power Used to switch an external relay to power the CAN ECU. Exact timing of this
output is dependent upon the type of the engine ECU
CAN ECU Shutdown The engine ECU has indicated that a
Shutdown alarm is present.
Inactive when no Shutdown alarm
from the ECU is present
CAN ECU Stop Active when the DSE controller is requesting that the CAN ECU stops the
engine.
CAN ECU Warning The engine ECU has indicated that a
Warning alarm is present.
Inactive when no Warning alarm
from the ECU is present
Charge Alternator Failure
(Alarm or Pre-Alarm)
Indicates that there is a charging fault
with the auxiliary charging alternator
• When the set is at rest
• During the starting sequence
before the safety delay timer
has expired
Check Sync
IEEE 37.2 – 25 Synchronising or
Synchronising Check Relay
Indicates that the internal check synchroscope has determined that the
supplies are in sync.
Clear Mains Decoupling
Active when a digital input configured to Clear Mains Decoupling is active
Close Generator Button Pressed Active when the Close Generator
button on the front fascia is pressed
Inactive when the button is released
Close Gen Output
IEEE 37.2 – 52 ac circuit breaker
Used to control the load switching
device. Whenever the 8600 module
selects the generator to be on load this
control source will be active.
Inactive whenever the generator is
not required to be on load
Close Gen Output Pulse
IEEE 37.2 – 52 ac circuit breaker
Used to control the load switching device. Whenever the DSE8600 module
selects the generator to be on load this control source will be active for the
duration of the Breaker Close Pulse timer, after which it will become inactive
again.
Combined Mains Failure
Active when the mains supply is out of limits OR the input for Auxiliary Mains
Failure is active
Combined Maintenance alarm Indicates that one of the maintenance alarms is active
Combined Remote Start Output Indicates that a remote start input is active.
Combined Under and Over
frequency alarm
IEEE 37.2 - 81 frequency relay
Active when the generator is shutdown due to either under OR over frequency
Combined Under and Over
frequency pre-alarm
IEEE 37.2 - 81 frequency relay
Active when the generator alarm for either under OR over frequency is active
Combined Under and Overvoltage
alarm
IEEE 37.2 – 27AC under voltage relay
IEEE 37.2 – 59AC over voltage relay
Active when the generator is shutdown due to either under OR overvoltage
Combined Under and Overvoltage
pre-alarm
IEEE 37.2 – 27AC under voltage relay
IEEE 37.2 – 59AC over voltage relay
Active when the generator alarm for either under OR overvoltage is active
