AC Voltmeter (M2)
The voltmeter indicates the generator output voltage in each phase-to-neutral (A-N, B-N and
C-N) or phase-to-phase (A-B, B-C and C-A) as selected by the METER SELECT switch. The
voltmeter has a scale of 0 to 300 V.
•
AC Ammeter (M1)
The ammeter indicates the generator output current in each phase (A, B and C) as selected
by the METER SELECT switch. The ammeter has a scale of 0 to 520 A.
•
Fault Code meter (M6)
The function of the fault code meter is to indicate to the operator, that an abnormal condition
of over voltage, under frequency, etc. occurred, which caused the protective monitoring
system to function. When one of the circuits are activated, it shows the code on the fault
code meter. The fault will remain on for a short period or until the TEST/RESET
switch is
pressed. Pressing the TEST/RESET switch can also test the fault code meter operation. A
meter test should be performed only when disconnected from a load, as the contactor(s) will
open during the test cycle.
•
Front LED Display (A5)
The front LED display indicates which voltage (A-N, A-B, etc…) and amperage are shown on
the meters and whether EF BY-PASS is present or bypassed. This EF BY-PASS indicator
serves to warn the operator that if the plug interlock system was by-passed any exposed
cable may be live.
•
DC Voltmeter [Optional with TR]
The voltmeter monitors and displays the transformer-rectifier’s output voltage. The voltmeter
is an analog type and indicates the output voltage from 0 to 50 VDC.
•
DC Ammeter [Optional with TR]
The ammeter monitors and displays the transformer-rectifier’s output current. The ammeter is
an analog type and indicates the output voltage from 0 to 2500 A.

•
LAMPS switch (S74)
The LAMPS switch controls the lights. Meters are lighted from inside the control panel.
•
ENGINE HEATER switch (S79)
The ENGINE HEATER switch activates the standard cold starting aid (manifold air intake
heater), which is totally controlled by the engine’s ECM. Once the heater is activated, the
engine’s ECM will control the operation. The heater typically stays on for a period of
approximately 30 seconds, which is indicated by the light on the push-button. When the light
goes out, the engine is ready to start. Starting a cold engine without first warming the engine
will lead to excessive white smoke exhaust and the engine may be hard to start.
