Fault and Status LEDs and Lamp Test Switch
Alarm Horn. Horn sounds giving a minimum 90 dB at 0.1 m
(0.3 ft.) audible alarm when a warning or shutdown fault
condition exists except on high/low battery voltage or EPS
supplying load.
Alarm Silenced. Red LED on lamp test switch lights when
alarm horn is deactivated by alarm silence switch.
Alarm Silence Switch. Lamp test switch quiets the alarm
during servicing. The horn will reactivate upon additional faults.
ATS Fault. Red LED lights when ATS fails to transfer.
Battery Charger Fail. LED lights if battery charger
malfunctions. Requires battery charger with alarm contact.
Battery Voltage Hi/Lo. LED flashes if battery or charging
voltage drops below preset level. LED lights steady if battery
voltage exceeds preset level.
Common Fault. LED lights when a single or multiple
common faults occur.
Communication Status. Green LED lights indicating
annunciator communications functional. Red LED indicates
communication fault.
EPS Supplying Load. LED lights when the Emergency Power
System (EPS) generator set is supplying the load (APM402,
APM603, APM802, and Decision-Makerr 550, 3000, 3500,
6000, and 8000 controllers) or when transfer switch is in the
emergency position (Decision-Makerr 3+ controller).
Emergency Stop. LED lights and engine stops when
emergency stop is made. May require a local emergency
stop switch on some Decision-Makerr 3+ controllers.
Generator Running. LED lights when generator set is in
operation.
High Engine Temperature. Red LED lights if engine has shut
down because of high engine coolant temperature. Yellow
LED lights if engine coolant temperature approaches shutdown
range. Requires warning sender on some models.
Lamp Test (Switch). Switch tests all the annunciator indicator
LEDs and horn.
Low Coolant Level/Aux. LED lights when engine coolant level
is below acceptable range on radiator-mounted generator sets
only. When used with a Decision-Makerr 3+ controller, the LED
indicates low coolant level or an auxiliary fault shutdown.
Requires user-supplied low coolant level switch on remote
radiator models.
Low Coolant Temperature. LED lights if optional engine block
heater malfunctions and/or engine coolant temperature is too
low. Requires prealarm sender on some models.
Low Cranking Voltage. LED lights if battery voltage drops
below preset level during engine cranking.
Low Fuel (Level or Pressure). LED lights if fuel level in tank
approaches empty with diesel models or fuel pressure is low on
gas models. Requires customer-supplied switch.
Low Oil Pressure. Red LED lights if generator set shuts down
because of insufficient oil pressure. Yellow LED lights if engine
oil pressure approaches shutdown range. Requires warning
sender on some models.
Not In Auto. LED lights when the generator set controller is not
set to automatic mode.
Overcrank. LED lights and cranking stops if engine does not
start in either continuous cranking or cyclic cranking modes.
Overspeed. LED lights if generator set shuts down because of
overspeed condition.
System Ready. Green LED lights when generator set master
switch is in AUTO position and the system senses no faults.
Red LED indicates system fault.
User-Defined Digital Inputs #1- #5. Monitors five digital
auxiliary inputs (can be configured as warnings or shutdowns).
User-defined digital inputs are selected via the RSA III master
