standing in water, while barefoot, or while hands or
feet are wet. DANGEROUS ELECTRICAL SHOCK
MAY RESULT.
• If people must stand on metal or concrete while
installing, operating, servicing, adjusting, or repairing this equipment, place insulative mats over a dry
wooden platform. Work on the equipment only while
standing on such insulative mats.
• Wire gauge sizes of electrical wiring, cables, and cord
sets must be adequate to handle the maximum electrical current (amperage) to which they will be subjected to.
• Before installing or servicing this equipment, make
sure that all power voltage supplies are positively
TURNED OFF at their source. Failure to do so will
result in hazardous and possibly fatal electrical
shock.
• When installed with an automatic transfer switch, the
generator may crank and start anytime, without
warning. To prevent injuries caused by sudden startup, disable the generator’s automatic start circuit
before working on, or around, the unit. Then, place
a “Do Not Operate” tag on the generator control
panel and on the transfer switch.
• In case of an accident caused by electric shock,
immediately shut down the source of electrical
power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting
implement, such as, a rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical
help.
• Never wear jewelry when working on this equipment.
Jewelry can conduct electricity, resulting in electric
shock, or may get caught in moving components,
causing injury.
F
IRE HAZARDS
• For fire safety, the generator and related equipment
must be installed and maintained properly.

1.1 OVERVIEW
The “C” option control panel is an analog generator
set control panel designed for Generac’s range of
standby generators. It allows for either manual or
automatic startup and shutdown.
The panel is housed in a steel sheet metal enclosure
that meets NEMA 1 specifications. The front face of
the panel includes a number of analog meters and
gauges that indicate generator operating conditions,
several indicator lamps for annunciation of engine
fault shutdowns, and various other generator set controls.
1.2 CONTROL PANEL COMPONENTS
The control panel contains one main printed-circuit
board (PCB), the automatic voltage regulator (AVR),
optional components, such as battery monitor, dry
contact boards, run relay, etc., and terminal blocks
for external connections.
To find locations of the circuit board, refer to
Appendix 2 for the control panel exploded view.
Remove the 15-amp fuse from the front of the
panel during all engine maintenance to guard
against accidental or remote startup.
1.3 OPTIONAL EQUIPMENT
1.3.1 REMOTE ANNUNCIATOR PANEL
When connected to the generator via a 19 wire connection link, this multi-light remote indicator panel will
display the generator’s status.
1.3.2 DRY CONTACTS
This panel is similar to the remote annunciator, but, in
addition to indicator lights, it provides relay contact
closures for status (e.g., alarms). The dry contact
boards are form C rated contacts. The five function dry
contacts are normally open (N.O.). The six function dry
contacts are either normally open (N.O.) or normally
closed (N.C.).

• Over/Under current relay
1.4 PANEL FACE COMPONENTS
(FIGURE 1.1, PAGE 3)
1.4.1 AC VOLTMETER
This meter indicates the generator AC output voltage.
(Also see “Line-phase Selector Switch” and “Voltage
Adjust Potentiometer” in this section). To determine
the nominal rated AC voltage of the unit, refer to the
unit’s data plate.
NOTE:
Some generators are reconnectable to a variety of
voltages. Some units may be equipped with a
rotary “Voltage Selector Switch.” Be sure to read
the “Generator AC Lead Connections” section in
the Owner’s Manual.
1.4.2 AC AMMETER
This meter indicates the current draw of connected
electrical loads, in amps. (Also see “Line-phase
Selector Switch”). For continuous operation, never
exceed the rated maximum continuous current
capacity of the generator.
1.4.3 FREQUENCY METER
This meter indicates the generator’s AC output frequency in “Hertz” (cycles per second).

1.4.4 LINE-PHASE SELECTOR SWITCH
This four-position switch permits selection of either
line-to-line or line-to-neutral readings on the panel
voltmeter and ammeter. Switch positions are as follows:
1.4.5 VOLTAGE ADJUST POTENTIOMETER
This potentiometer permits the operator to “fineadjust” the generator’s AC output voltage. Adjustment
range is plus or minus five percent from the midpoint. Turn the knob clockwise to increase voltage,
counterclockwise to decrease voltage.
1.4.6 COOLANT TEMPERATURE GAUGE
This gauge indicates the engine coolant temperature.
Normal operating temperature should read between
185° to 215°F (85° to 102°C). If coolant temperature
exceeds a safe level, the engine shuts down automatically.
NOTE:
Actual coolant temperature reading may vary due
to variables, such as, ambient temperature,
applied load, or cooling system condition.
1.4.7 OIL PRESSURE GAUGE
This gauge indicates oil pressure during operation.
After warm-up, oil pressure should be about 25-90
psi. Generac recommends that the operator record
the normal oil pressure during initial startup.
Sudden changes in oil pressure after first starting
indicate a possible engine problem.
NOTE:
Engine oil pressure may vary, depending on oil
viscosity, oil temperature, engine speed, ambient
temperature, etc. The engine automatically shuts
down if oil pressure drops below a safe level.
(10 psi.)
1.4.8 DC AMMETER
The engine is equipped with a belt-driven DC alternator, which charges the battery while the unit is running. This ammeter indicates the rate of charge to the
battery during operation. If the needle drops to the
left of zero, the battery is discharging. Investigate and
correct this problem immediately. Erratic movement
of the needle should also be corrected immediately.
1.4.9 HOURMETER
The hourmeter provides a continuous indication of
engine/generator operating time, in hours and tenths
of hours. Use the hourmeter with the periodic maintenance schedule.

1.4.10 START/STOP SWITCH
Use this switch to crank and start the engine manually, or to shut down an operating engine.
• To crank and start engine, first set the
Auto/Off/Manual switch to its “Manual” position.
• Hold the Start/Stop switch at “Start.” When the
engine starts, release the switch to its center (run)
position.
• To shut engine down, move the switch to its “Stop”
position.
1.4.11 AUTO/OFF/MANUAL SWITCH
This safety switch should be used to prevent automatic startup of the engine when working on the
engine/generator. Use the switch as follows:
Auto Position
Always set switch to AUTO for automatic system
operation. This means that, when this generator is
installed with a GTS-type automatic transfer switch,
the generator automatically cranks and starts when
the utility source voltage drops below a preset level,
or the unit exercises, if programmed to do so.
Off Position
The engine cannot be started either automatically or
manually. Always set switch to OFF before working
on, or around, the engine-generator.
Manual Position
The engine can be cranked and started manually
using the panel Start/Stop switch. The engine will not
start automatically.
NOTE:
Also see “Engine Monitor Panel.” With switch set
to either OFF or MANUAL, a “Not in Automatic
Start Mode” lamp lights up on the panel.
1.4.12 PANEL FUSE
This fuse protects the control console’s DC circuits
against overload. If the fuse element melts open due
to an overload, engine cranking and startup will not
be possible. Should fuse replacement become necessary, use only an identical fuse (part number
022676).
1.5 ENGINE MONITOR PANEL
This panel has five advisory shutdown lamps for separate engine fault conditions, plus a “Not in
Automatic Start Mode” lamp. Cranking and starting
will not be possible while any one, or more, of engine
fault conditions lamps is lit, with the exception of
“Not in Auto” illuminated in the manual mode. The
following apply:
• A “lamp ON” condition indicates that fault condition has been “latched” by DC control/latch-crank
circuit board.
• If any one of the lamps is ON (fault condition
latched), the engine cannot be cranked either manually or automatically.
• To unlatch a fault (that is, to turn a lamp OFF) and
permit cranking, push the Test/Reset switch in.
The lamp will then go OFF, allowing for additional
cranking.
1.5.1 NOT IN AUTOMATIC START MODE
LAMP
This lamp comes ON to indicate that automatic startup of the engine is not possible. The lamp lights up
whenever the Auto/Off/Manual switch is set to OFF or
MANUAL.
1.5.2 OVERCRANK LAMP
The control console houses a DC control/latch-crank
circuit board (the “C” board) that controls engine
startup and shutdown. During automatic startup, the
engine cranks for about 14 seconds, rests for about
eight seconds, and so on, until eight crank-rest cycles
have occurred. At the end of eight attempts, cranking
stops, and the overcrank lamp goes ON.
1.5.3 HIGH COOLANT TEMPERATURE LAMP
This lamp comes ON if coolant temperature is too
high or coolant level is too low. The engine shuts
down automatically when such unsafe conditions
occur. The following apply:
• If the engine is started with an existing high coolant
temperature or low coolant level condition, the
engine shuts down, and the lamp comes ON when
engine speed reaches about 1000 rpm.
• If the engine starts normally but high temperature/low coolant level develops later, the engine
shuts down, and the light comes ON immediately.
1.5.4 OVERSPEED LAMP
An engine overspeed above a safe limit causes the
engine to automatically shut down, which turns ON
the indicator lamp. The overspeed lamp comes on
when the unit is run at a 15% faster rpm than rated.

1.5.5 LOW OIL PRESSURE LAMP
This lamp lights up (latches) to indicate low oil pressure in the engine as follows:
• During cranking, after engine has reached 800 to
1000 rpm, the circuit allows four seconds for oil
pressure to build.
• In auto mode, if the unit runs above 800-1000 rpm
for more than four seconds, and oil pressure is
below a safe level, the engine shuts down, but the
lamp does NOT go ON. The system then actuates
eight restart attempts; the engine shuts down, and
the lamp goes ON.
• If the engine starts normally with good oil pressure, but oil pressure drops later, the system waits
five seconds for oil pressure to be restored. If pressure is still low after a five-second delay, the engine
shuts down, and the lamp goes ON immediately.
1.5.6 RPM SENSOR LOSS LAMP
Units with the “C” Option console are equipped with
an rpm sensor, which is mounted directly over the
engine flywheel gear teeth. This sensor is a magnetic
pickup that emits an electrical pulse at the passage of
each flywheel gear tooth. Sensor electrical signals are
used by the DC control/latch-crank circuit board as
engine speed (rpm) signals. The circuit board uses
these rpm signals (a) to establish a starter lockout
speed, and (b) to shut down the engine if the engine
runs too fast (overspeed). If the rpm signals to the
circuit board are lost, engine shutdown occurs, but
the lamp will not light, (i.e., the condition will not
latch), then, depending on whether the sensor signal
loss occurred during a manual or an automatic start
attempt, the following events occur:
Manual Startup
If the engine starts within two seconds after cranking
begins, shutdown occurs as soon as the Start/Stop
switch is released, but without a lamp ON condition
(latching does not occur). If engine does not start
within two seconds after cranking begins, which disables starting, the rpm sensor loss light goes ON.
Automatic Startup
The engine recranks within about one second after it
has stopped. If sensor loss persists, engine shuts
down, and lamp lights about two seconds after
cranking has restarted.
If engine starts within two seconds after recrank has
begun, the starter remains engaged until the two-second delay is over.
1.5.7 TEST/RESET SWITCH
To test all lamps, push this switch in. Following any
fault shutdown with any monitor panel lamp illuminated, engine cranking is inhibited. To reset the system (unlatch a fault) and crank the engine again,
push the switch in (lamp must go out). If the switch
is actuated with the engine running, only the lamps
will be tested. The engine will not shut down.
NOTE:
If engine shuts down due to some unmonitored
problem (such as, out of fuel or failed ignition system), none of the lamps will come ON. If such an
unmonitored shutdown occurs with the
Auto/Off/Manual switch set to AUTO, engine
recranks and attempts to start for any of the cycles
remaining in the eight-crank limit. After all eight
crank cycles have been used, the engine shuts
down, and the OVERCRANK lamp goes ON.
1.6 OPTIONAL ANNUNCIATOR PANEL
Some units may come equipped with a factoryinstalled annunciator panel having up to nine annunciated fault conditions displayed (Figure 1.2). This
optional panel is often called a “prealarm” panel,
since it warns of impending problems before an actual fault shutdown occurs.
The panel is designed to monitor various engine condition-sensing devices having normally-open (N.O.) or
normally-closed (N.C.) contacts.

9556 remote annunciator panels. The following apply
to the remote annunciator panels:
• It is designed for use with installation having a
Generac Power Systems GTS-type transfer switch
and a “C” Option control panel.
• The panel is available in both flush-mounted
(Model 9556) and surface-mounted (Model 9555)
configurations.
• The panel has a built-in audible alarm horn, with a
reset switch to turn off the horn without disturbing
the lighted indication.
• Remote monitoring of the standby generator set
provides enough information to avoid unnecessary
maintenance trips to the generator site.
Figure 1.3 — Optional 18-Light Remote
Annunciator
1.8 STANDARD ALARM RELAY
The generator’s DC control/latch-crank circuit board
is equipped with an alarm relay “driver”. All units
with “C” Option control panels are equipped with an
alarm relay that is connected to the circuit board
driver (Figure 1.4). If any one or more of the five
annunciated shutdown faults occur, the circuit board
driver energizes the optional alarm relay.
A remote-mounted alarm or annunciator device may
be connected across the relay contacts so that a failure will turn on the remote alarm or device. The connected alarm device may range from an alarm horn
to a warning light to a telephone dialer with a prerecorded message. The alarm relay normally-open,
normally-closed, and common contacts are shown in
Figure 1.4.
Figure 1.4 — Standard Alarm Relay
1.9 PREPARATION BEFORE STARTUP

2.2.3 PREVENTING AUTOMATIC STARTUP
When installed with an automatic transfer
switch, Generac standby generators can crank
and start suddenly, without warning, when
UTILITY source voltage drops below a preset
value. To prevent possible injuries caused by
such sudden starts, disable the automatic
transfer switch before working on, or around,
the generator. Use any one, or more, of the following methods to disable the automatic start
function:
• Set the generator’s Auto/Off/Manual switch to OFF.
Neither a manual nor an automatic start can be
accomplished with this switch set to OFF.
• Remove the fuse from the generator control panel.
To remove the fuse, push fuse holder cap in and
turn cap counterclockwise. Remove cap and fuse
element.
• Refer to the automatic transfer switch instructions.
If the transfer switch is so equipped, set its Safety
Disconnect switch to MANUAL position to prevent

Section 1 — General Information
Remote Annunciator Panels
1.1 THREE LIGHT REMOTE
ANNUNCIATOR
The Generac Three Light Remote Annunciator
(Figure 1.1) provides a valuable reference when used
with the Generac automatic transfer switch and
standby generator with a C option control panel.
This equipment is designed to be mounted remotely
from the standby generator set. The panel, when
properly interconnected with a Generac standby generator system and transfer switch, annunciates up to
three (3) standby electric system operating parameters.
• Utility Power Supply: This light comes ON when
customer electric loads are being powered by the
NORMAL (utility) power source.
• Emergency Power Supply: This light comes ON
when customer electric loads are being powered by
the EMERGENCY (standby) power source.
• Generator Fault Light: This light comes ON when
the generator engine has shut down automatically
due to a fault condition (such as low oil pressure,
high coolant temperature, overcrank, overspeed,
or RPM sensor loss). Fault conditions that will
result in an automatic engine shutdown are discussed in the INSTRUCTIONS AND PARTS MANUAL for the applicable generator set.

1.1.1 INSTALLATION
Mount the annunciator at any convenient location
near or remote from the standby generator. Mounting
dimensions are shown in Appendix ???. Holes are
provided for fastening the panel to a desk, wall or
other convenient object. Four 7/8” (22mm) holes are
also provided for routing of required wiring into the
panel. Installation must comply with all applicable
codes and regulations.
Required wiring between the Model 8848 annunciator, the Generac generator meter and control (upper)
panel, and transfer switch auxiliary contacts are
shown in Appendix ???, Interconnection Diagram.
NOTE:
Two different types of auxiliary contacts may be
encountered on Generac transfer switches.
1.2 FIVE LIGHT REMOTE
ANNUNCIATOR
The Model 8617 Remote Annunciator Panel (Figure
1.2), when properly interconnected with a Generac
standby generator equipped with an Option C control
panel, will provide remote annunciation of the same
five engine operating parameters as the generator
panel. The remote panel mounts five advisory lamps.
On occurrence of one or more of the panel monitored
faults, the applicable lamp will illuminate and the
horn will sound. Both the lamp(s) and the Alarm
Horn can be turned OFF by depressing the Reset
switch. All five lamps may be tested by actuating the
Test switch. The following engine fault conditions will
be indicated on the annunciator panel:
• Low Engine Oil Pressure
• High Engine Coolant Temperature/Low Coolant
Level
• Overcrank Condition
• Overspeed Condition
• RPM Sensor Loss Condition

Remote Annunciator Panels
1.2.1 OPERATION
Both the remote and generator panel advisory lamps
are controlled by a single DC CONTROL-LATCHCRANK circuit board housed in the generator control
console. Engine mounted, normally open (N.O.)
switches and sensors provide the necessary signal to
the circuit board on occurrence of a monitored
engine fault. should any one (or more) of the monitored faults occur, an automatic engine shutdown,
illumination of the applicable lamp(s), and sounding
of the Alarm Horn will occur. circuit board action will
then “latch” the fault. That is, the applicable lamp(s)
will remain ON after engine shutdown. While any
lamp remains lighted (latched), further attempts at
generator cranking and startup are inhibited. A 12
volt DC input is required to operate the panel.
NOTE:
See applicable standby generator owner’s manual
for more detailed operational description of
remote and generator panel lamps.
1.2.2 CUSTOMER CONNECTIONS
Suitable, approved wiring must be purchased for
interconnection of the Remote Annunciator Panel
with Terminal block TB2. Connect each wire to a
numbered terminal block screw and to an identically
numbered terminal in the remote annunciator panel.
A total of nine wires are required. Numbered terminals may be identified as follows:
• #94 — Low Oil Pressure Shutdown
• #95 — High Coolant Temperature/Low Coolant
Level Shutdown
• #96 — Overcrank Shutdown
• #97 — Overspeed Shutdown
• #98 — RPM Sensor Loss Shutdown
• #137 — Test Switch Connections
• #138 — Reset Switch Connections

1.3 18 LIGHT REMOTE ANNUNCIATOR
The Model 9555 Remote Annunciator Panel is a self
contained system, utilizing solid state circuits to
annunciate up to sixteen (16) engine-driven generator
operating parameters (Figure 1.3). The system meets
NFPA (National Fire Protection Association) specifications for standby electric power systems.
The system will monitor any sensing device having
normally-open (N.O.) contacts which provide a +DC
signal to the applicable panel lamp on contacts closure. On contacts closure, both an alarm lamp and
an alarm horn are activated and latched in to manual reset. The alarm horn may be silenced without disturbing the visual indication and with any subsequent alarm re-activating the horn. The system
includes a test circuit.
NOTE:
The one exception to the normally-open (N.O.)
contacts rule is the LOW BATTERY VOLTAGE
lamp. This lamp must be connected to normallyclosed (N.C.) contacts on the battery monitor circuit board, located in the generator control panel.

1.3.1 GENERATOR STOP SIGNALS
All signals occur when generator shutdown occurs as a
result of the failure indicated by the illuminated
lamp(s).
1. High Water Temperature/Low Water Level: This
lamp comes ON and the horn sounds when the generator’s high temperature alarm is active.
2. Low Oil Pressure: This lamp illuminates and the
alarm horn sounds when the generator’s low oil
pressure alarm is active.
3. Overspeed: This lamp turns ON and the alarm
horn sounds when the generator’s overspeed alarm
is active.
4. Overcrank: This lamp turns on and the alarm horn
sounds when the generator’s overcrank alarm is
active.
5. Sensor Loss: This lamp illuminates and the alarm
horn sounds when the generator’s rpm sensor loss
alarm is active.
1.3.2 LATCHABLE SIGNALS
The following signals can be individually selected by
means of miniature rocker switch on the Remote
Panel’s monitor circuit board. The available switch
positions are “Latch On” and “Latch Off”. “Latch Off ”
indicates the lamp will turn ON only when the signal is
present. “Latch On” indicates the lamp will be ON until
the monitor “Reset” switch is pressed. The alarm horn
sounds when “Latch” is selected. The horn will stay ON
until either the “Rearm Horn” or the “Reset” switch is
pressed.
1. Low Battery Voltage: This lamp illuminates when
the generator’s battery voltage drops low, indicating
a discharge condition.
2. High Battery Voltage: This lamp will turn ON when
generator battery voltage is high, indicating an overcharge condition.
3. Battery Charger Failure: This lamp will illuminate
on failure of the generator’s battery charge system.
4. Low Fuel: This lamp illuminates when an occur-
rence of a low fuel level in the generator’s fuel tank.
5. Pre-alarm/High Temp.: This lamp will illuminate
to warn of an approaching or imminent high coolant
temperature shutdown.
6. Pre-alarm/Low Temp.: This lamp will illuminate
when the coolant temperature has decreased, indicating an engine coolant heater failure.
7. Pre-alarm/Low Oil Pressure: This lamp will illuminate in advance of a low oil pressure shutdown. It
indicates engine oil pressure has decreased to near
the point of automatic shutdown.
8. Generator Run: This lamp illuminates to advise
that the generator has started and/or is running.
Lamp ON indicates the generator “run” circuit is
active (Wire #14 on units with 12 volts DC engine
control system, Wire #219 on units with 24 volts
DC engine control system).
1.3.3 OTHER LAMPS
1. System Ready: This lamp will be ON to indicate
the generator set is able to run. If the lamp is OUT,
a “stop” signal is present.
2. Not In Auto: This lamp will illuminate to indicate
the generator’s Auto-Off-Manual switch is NOT set
to “Auto” )that is, the switch is set to either “Manual”
or “Off” and automatic operation is not possible).
3. Horn Switch Off: This lamp will turn ON to indi-
cate the horn switch on the annunciator panel is
turned OFF. With the horn switch set to OFF, lamps
will not be affected. However, the alarm horn will
not sound.
4. Line Power: This lamp will be ON when the automatic transfer switch main contacts are in their
“Utility” position (and connected to the “Utility”
power supply).
5. Generator Power: This lamp will turn ON when the
transfer switch main contacts are in their “Standby”
position, i.e., load is connected to the generator
power supply.
1.3.4 PANEL WIRING INTERCONNECTIONS
All INPUT signal connections are made at a 24 screw
terminal block, located on the Remote Panel’s MONITOR CIRCUIT BOARD. Use purchased No. 14 AWG
wiring for all interconnections. Maximum recommended distance between the Remote Panel and the standby
generator should not exceed 1000 feet (305 meters). See
page 36 for installer’s wiring interconnections.
1.4 TROUBLESHOOTING
Troubleshooting the 18 lamp annunciator is limited to
checking wire connections at the generator panel, transfer switch and annunciator, and checking for proper DC
inputs to annunciator terminal strip. If all connections
and input DC voltage signals are good but a problem
still exists with the annunciator operation, replace
annunciator circuit board.
1. Automatic Generator Stop Signals: The horn and
lamp are always latched if one of these signals
occurs. Generator stop lamps and horn can be reset
by either the test/reset switch at the annunciator or
reset of fault lamps at the generator.
2. Test/Reset: Pressing the test/reset switch energizes
all lamps except the “horn switch off” lamp and the
horn. Release of the switch resets the lamps and
horn. The test/reset switch has no effect on fault
indicators at the genset.

Remote Annunciator Panels
32 Generac®Power Systems, Inc.
Section 1 — General Information
Remote Annunciator Panels
3. Latch Select: The lamps and horn can be selected
to be latched by on-board switch. Unlatched signals
activate the lamp only; the lamp is de-energized if
the fault signal is cleared. Latching provides an
audible signal plus keeps the lamp energized as an
indicator even if the pre-alarm fault has been
cleared.
4. Rearm: The rearm clears the horn but not the
lamps. The lamps are held active by either latch or
fault signal. After rearm, horn is enabled to sound if
another fault occurs.
5. System Ready Lamp: This lamp indicates the
genset is operational. The lamp is energized whenever power is applied to the annunciator circuit and
no generator stop signals are present.
6. Line-Power/Gen Power Lamps: This indicates the
position of the transfer switch. When load is transferred to the genset, the “Generator Power” lamp is
lit and the horn sounds.
7. Horn Switch Off Lamp: This lamp indicates that
power to the horn has been disconnected by a horn
disable switch.
8. Annunciator Delays: Signals will be annunciated if
the exist for the following minimum times:
• Not in Auto, Horn Off, 100 seconds.
• Pre-alarm Low Oil Pressure, 10 seconds.
• All others, 1 second.
