TABLE 2-4. DIAGNOSTIC CONTROLS AND INDICATORS (continued)
CONTROL OR INDICATOR
BACKPLANE MODULE (continued)
LED 13 (red) indicator
Short circuit indication. If indicator is lit, indicates a short
circuit condition affecting generator set output has been
LED 12 (green)
LED 11 (green)
Remote display connection. Indicator blinks on and off when
remote display is properly connected. If not lit, indicates no
remote display connection has been made.
LED 10 (green)
Data validity from remote display. Indicator blinks on and off
to indicate remote data is being received properly. If not lit,
remote data is not being received properly. If not lit, can also
indicate no remote display function has been connected.
LED 9 (green)
Status of the main generator power bus. If indicator is lit, the
bus is energized (voltage is present), and voltage is available
for paralleling operation. If not lit, indicates the generator set is
operating in a stand-alone mode.
LED 8 (red)
LED 7 (red)
Network failure. If indicator is lit, indicates the CIM is not
communicating with the I/O interface module. If not lit,
indicates the CIM is communicating properly.
LED 6 (red)
Emergency stop. If indicator is lit, indicates the
EMERGENCY STOP switch has been activated. If not lit,
indicates normal running condition.
LED 5 (red)
CMOS voltage. If indicator is lit, indicates voltage necessary
for CMOS device operation is too low. If not lit, CMOS device
voltage source is sufficient.
LED 4 (green)
LED 3 (green)
Heartbeat. If indicator is blinking on and off, indicates proper
operation of this module. If not lit, indicates module has no
power applied or has failed.
LED 2 (green)
LED 1 (green)
If indicator is lit, fuel pump is operating. If not lit, fuel pump is
AUTOMATIC VOLTAGE REGULATOR
AC SENSING (green LED)
This indicator is normally lit, indicating the AC sensor is
sending the proper signal to this module.
DC SUPPLY indicator (green
This indicator is normally lit, indicating that the module's
internal DC supply is operating. The source for input power to
this module is the AC output of the generator set. Therefore,
the indicator will not be lit until the generator set is providing
power output to a load.
FIELD VOLTAGE (green LED)
This indicator is normally lit. It indicates field voltage is
present, which means the generator is developing AC power.
