4.5.3 OUTPUT SOURCES
The list of output sources available for configuration of the module relay outputs also applies to the LED
configuration and expansion relay outputs.
Under the scope of IEEE 37.2, function numbers can also be used to represent functions in microprocessor devices and
software programs. Where the DSE output functions can be represented by IEEE 37.2, the function number is listed below.
NOTE: - Output selection is dependant on controller.
Output source
Activates… Is not active….
Not Used
The output will not change state (Unused)
Air Flap Alarm This output indicates that the air-flap is closed; to operate it requires an input
configured as ‘Air-flap closed’ connected to the external air-flap switch.
Air Flap Relay
Normally used to control an air flap, this
output becomes active upon an Emergency
Stop or Over-speed situation.
Inactive when the set has come to rest
Alternative Config 1-3 selected
Indicates which of the three alternative configurations has been selected (if any)
Alarm Mute
Indicates that an alarm mute operation is in progress by digital input
Alarm Reset
Indicates that an alarm reset operation is in progress by digital input
Arm Safety On Alarms
Becomes active at the end of the
safety delay
timer whereupon all alarms configured to ‘From
Safety On’ become active
Inactive when :
• When the set is at rest
• In the starting sequence before
the Safety Delay timer has
expired
Audible Alarm
IEEE 37.2 – 74 alarm relay
This output indicates that the internal
sounder is operating to allow it to feed an
external sounder. Operation of the Mute
pushbutton will reset this output once
activated.
Inactive if the internal sounder is not
operating.
Auto Mode
Active when the controller is in AUTO mode Inactive in any other mode.
Auto Start Inhibit
IEEE 37.2 – 3 Checking or
Interlocking relay
Indicates that an auto start inhibit operation is in progress.
Battery High Voltage
IEEE 37.2 – 59DC over voltage relay
This output indicates that a Battery Over
voltage alarm has occurred.
Inactive when battery voltage is not High
The outputs are in alphabetical
order with the parameter first. For
instance for overspeed output, it’s
listed as Engine Overspeed.
