Common Alarm
IEEE 37.2 – 74 alarm relay
Active when one or more alarms (of any
type) are active
The output is inactive when no
alarms are present
Common Electrical Trip
IEEE 37.2 – 74 alarm relay
Active when one or more Electrical trip
alarms are active
The output is inactive when no
electrical alarms are present
Common Mains Decoupling Alarm
Indicates 1 or more of the decoupling alarm have activated
Common Shutdown
IEEE 37.2 – 74 alarm relay
Active when one or more Shutdown
alarms are active
The output is inactive when no
shutdown alarms are present
Common Warning
IEEE 37.2 – 74 alarm relay
Active when one or more Warning alarms
are active
The output is inactive when no
warning alarms are present
Coolant Cooler Control
IEEE 37.2 – 23 temperature control
device
Activated by the Coolant Cooler Control in conjunction with the Coolant
Temperature Sensor.
Coolant Heater Control
IEEE 37.2 – 23 temperature control
device
Activated by the Coolant Heater Control in conjunction with the Coolant
Temperature Sensor.
Coolant Temperature Switch Active when a high coolant temperature alarm is triggered by a coolant
temperature switch
Cooling Down Active when the Cooling timer is in
progress
The output is inactive at all other
times
Data Logging Active Active when data logging option is enabled.
DC Power On Indicates that the module is powered on and operating
Dead Bus Run on Timer Active Indicates that the set has closed onto the bus and that the Dead Bus Run On
Timer is in progress. When this has expired, the Load Demand Scheme is
activated.
Digital Input A - K Active when the digital input is active Inactive when :
• If the input is not active
• If the input is active but
conditioned by activation
delay, safety timer or
Arming requirements.
Down Button Pressed Active when the Down button on the front
fascia is pressed
Inactive when the button is
released
Dummy Load Control (1-5) Becomes active when the engine kW falls
below the Dummy Load Control Trip
Setting.
Inactive when the engine kW
returns to above the Dummy
Load Control Return setting.
Duty Select
Indicates that a digital input configured to Duty Select is active.
Droop Enable
Becomes active when an input configured to Droop enable is active or if Droop
Enable has been activated in the module configuration (CAN engine only)
Earth Fault
IEEE 37.2 – 71 level switch
Indicates that an earth fault alarm is active.
EJP1 / EJP2 Indicates that an input configured to EJP1 or EJP2 is active
Emergency Stop
IEEE 37.2 – 86 lockout relay
Active when the Emergency Stop input has been activated
Energise to Stop
Normally used to control an Energise to
Stop solenoid, this output becomes
active when the controller wants the set
to stop running.
Becomes inactive a configurable
amount of time after the set has
stopped. This is the ETS hold
time.
External Panel Lock
Active when digital input External Panel Lock is active
Fail to Stop
IEEE 37.2 - 48 Incomplete Sequence
Relay
If the set is still running a configurable amount of time after it has been given
the stop command, the output will become active. This is the Fail to stop timer.
Fail to Start
IEEE 37.2 - 48 Incomplete Sequence
Relay
Becomes active if the set is not seen to be running after the configurable
number of start attempts.
Fail to Synchronise
IEEE 37.2 - 48 Incomplete Sequence
Relay
Becomes active if the module fails to synchronise after the fail to sync timer.
Fan Control Energises when the engine becomes available (up to speed and volts). This
output is designed to control an external cooling fan.
When the engine stops, the cooling fan will remain running for the duration of
the Fan Overrun Delay.
