3.29 Remote/Transfer Switch

See Graphic: wc_gr002611

When the generator is used as a standby power supply, it must be
equipped with a device which isolates it from the utility’s distribution
system.

DANGER

Failure to isolate the generator from the utility’s electrical
distribution system could cause output from the generator to
backfeed into the utility lines and cause injury or death to utility
workers!

The same is true if using the generator as a backup to some other type
of power supply system.

A transfer switch is designed to transfer electrical loads from the
normal power source (utility) to the emergency power source
(generator) when normal voltage falls below a prescribed level.

The transfer switch automatically returns the load back to the normal
source when power is restored back to operating levels.

WARNING

DANGER

Installation of a transfer switch or other type of remote starting device
is the responsibility of the generator user. Installation of such devices
must be performed by a qualified electrician following all directions
supplied by the manufacturer of the switch. If attaching generator to a
power supply normally serviced by a utility company, notify the utility
company and check local and state regulations. Familiarize yourself
with all instructions and warning labels supplied with the switch.

The bond bar (t), connecting the neutral and ground lugs, may need to
be removed for standby power applications. Check with NEC and local
regulations for compliance requirements.

When using the generator as a standby or substitute power supply,
make sure the voltage and phase rotation of the line connections
match those of the utility lines, or of any other power source normally
used. Failure to match phase rotation and voltage may cause

equipment connected to the generator to operate incorrectly!
This could create unsafe operating conditions.

Lethal voltage is always present in the transfer switch once it has been
properly installed!

tongue.

3.30.6 On trailers with surge or electric brakes, connect the breakaway cable
(b) on the trailer coupler to the rear bumper or frame of the vehicle.
This cable will actuate the brake system on the trailer if both the
coupling and safety chains have failed. The breakaway cable is not a
parking brake and should not be used as one.

3.30.7 Check that all fasteners on the coupling are secure.

3.30.8 Check the tread wear and inflation on tires. Make sure that all lug nuts
are in place and are tight.

3.30.9 Check the operation of the optional surge brakes by braking the
vehicle at a slow speed before entering traffic. Both the vehicle and the
trailer should brake smoothly. If the trailer seems to be pushing, check
the fluid level (d) in the surge brakes or the operation of the electric
brakes.

A film of grease on the coupler will extend coupler and ball life and
eliminate squeaking. Wipe the coupler and ball clean and apply fresh
grease each time the trailer is towed.

NOTICE: When towing, maintain extra space between vehicles and
avoid soft shoulders, curbs and sudden lane changes. If you have not
pulled a trailer before, practice turning, stopping, and backing up in an
area away from heavy traffic.

DO NOT exceed 55 mph when towing a trailer.
In most states, large trailers must be registered and licensed by the

State Department of Transportation. Before towing, be sure to check
licensing requirements.

4.2 New Machines

4.2.1 Run generator at least 60–100% of continuous load for the first 100
hours.

4.2.2 Change engine oil and replace oil filter after the first 50 hours.

4.3 Resetting the Periodic Maintenance Timer

After maintenance has been performed on the generator, it is
necessary to reset the periodic maintenance timer.

• If the periodic maintenance timer is at zero, press the ENG. HRS
switch UP and hold for 10 seconds until the “TIME TO SERVICE”
resets to 250 hours.

• If the service time is greater than zero (maintenance was performed
prior to the timer running out) press and hold the ENG. HRS switch UP
and hold for 30 seconds. This will reset the “TIME TO SERVICE” to
250 hours.

4.4 Air Cleaner

See Graphic: wc_gr000511

Replace the air filter cartridge when yellow indicator of the engine air
filter gauge reaches the red line.

The air cleaner assembly contains a one-piece single element air filter
cartridge (c).

To replace the air filter cartridge:

• Remove the end cover (d), then discard the entire air filter cartridge.

• Insert a new air filter cartridge, then

• Re-install the end cover, making sure that the dust cap (e) is clean
and is pointing downward.

Periodically, make sure the inlet pipe (f) is free from obstructions.
Check all connections and make sure they are snug. An air leak at the

neck clamp, gauge connection, or intake pipe can quickly lead to
expensive engine repairs.

• Make sure that the intake piping (a) is fully engaged over the neck
of the filter to ensure a good seal.

• If the filter housing, gauge connection (b), neck, or inlet pipe are
crushed or damaged, replace them immediately.

4.5 Engine Lubrication

Check engine oil daily before starting engine.
DO NOT operate engine if oil level is below ADD mark on dipstick.

Always keep oil level within the crosshatch pattern or “full” mark on
dipstick.

Change oil after first 100 hours of operation and every 250 hours
thereafter. Refer to the engine manufacturer’s Operator’s Manual for
lubrication specifications.

Break-in Service

4.5.1 This engine is factory-filled with John Deere Engine Break-in Oil.
Operate the engine at heavy loads with minimal idling during the
break-in period. DO NOT exceed 100 hours of operation with break-in
oil.

4.5.2 If the engine has significant operating time at light load, or makeup oil
is required in the first 100 hour period, a longer break-in period may be
required. In these situations, an additional 100 hour break-in period is
recommended using a new change of John Deere Engine Break-In Oil
and a new John Deere oil filter.

NOTICE: DO NOT add makeup oil until the oil level is BELOW the
ADD mark on dipstick. John Deere Engine Break-In Oil (TY22041)
should be used to make up any oil consumed during the break-in
period.

4.5.3 During the first 20 hours, avoid prolonged periods of no load or
sustained maximum load operation. If engine is to run for longer than
5 minutes without a load, shut unit down.

4.5.4 After the first 100 hours, change engine oil and replace engine oil filter.
Fill crankcase with seasonal viscosity grade oil.

wc_tx000484gb.fm 50

G 50/G 70/G 85 Maintenance

4.6 Engine Coolant

Check the coolant level of the radiator with the engine cold. After initial
filling of radiator to 3/4" below bottom of filler neck, maintain proper
level in overflow bottle daily.

NEVER remove radiator cap or drain plug while engine is hot!
Pressurized coolant can cause serious burns.

WARNING

Shut off engine. Only remove radiator cap when it is cool enough to
touch with bare hands. Slowly loosen cap to relieve pressure first,
before removing it completely.

Solutions of antifreeze and supplemental coolant additives MUST be
used year-round. Automotive-type coolants do not contain the correct
coolant additives to protect heavy-duty diesel engines. They often
contain a high concentration of silicates which can damage the engine
and cooling system. Refer to engine Operator’s Manual for coolant
recommendations.

4.7 Trailer Maintenance

Tires - Keep tires inflated to the proper pressure as shown on the tire

sidewall, and check tread periodically for wear. Replace tires as
required.

Wheels - Check that lug nuts holding wheels are tight. Replace any
missing nuts immediately.

Axle Hubs - Grease axle hubs through grease fittings using a good
wheel bearing grease.

Brakes - Check operation of brakes before each trip.
Check level of brake fluid in actuator at front of trailer at regular

intervals. Fill to approximately 1" below top of reservoir using DOT-3
heavy-duty brake fluid. Tighten filler plug securely.

Note: If fluid level has fallen too low, bleed brake lines to remove any
air trapped in lines.

Maintenance G 50/G 70/G 85

4.8 Troubleshooting Automatic Shutdown

There are several automatic shutdown conditions: low oil pressure,
high coolant temperature, engine overspeed, engine underspeed,
engine overcrank, and low fuel. When these occur, the operator can
perform certain diagnostic tests to help identify the problem. Most of
these diagnostics deal with the engine.

The generator, however, can also cause problems. Consult a qualified
electrician or your nearest WACKER Dealer for possible causes of
generator problems. For SPN.FMI Diagnostic Codes, contact
WACKER or John Deere service departments.

Anytime the generator is down for service, secure it by closing and
locking all doors, and hang a "DO NOT RUN" sign on the metering

WARNING

panel.

Low Oil Pressure Shutdown

4.8.1 Check engine oil level using dipstick. Add oil if required.

4.8.2 Carefully inspect engine for oil leaks.

4.8.3 If oil level is good, start engine and verify loss of oil pressure. Shut
down engine immediately if oil pressure value does not read at least
15 psi within 5 seconds.

Check the oil pressure shutdown sender and connecting wiring on the
engine block. Check for Diagnostic Trouble Codes.

4.8.4 If oil level, oil pressure sender and connecting wiring are good, the fault
could be caused by an engine failure.

High Coolant Temperature Shutdown

4.8.1 Restart engine and read water temperature. Stop engine if
temperature is above 226°F. Normal engine operating temperature is
between 170°-190° F.

4.8.2 Allow engine to cool to a safe temperature and inspect coolant level in
radiator. Add coolant as needed.

4.8.3 Carefully inspect coolant hoses and engine block for leaks.

4.8.4 Check that fan belt for water pump is tight.

4.8.5 Check the high temperature shutdown sender and connecting wiring
on engine block. Check for Diagnostic Trouble Codes.

4.8.6 If sender and wiring are good, consult engine manufacturer’s
Operator’s Manual or Service Manual for possible causes of engine
overheating.

wc_tx000484gb.fm 52

G 50/G 70/G 85 Maintenance

Overspeed or Underspeed Shutdown

Restart engine and read the AC frequency meter. Meter should read
60 Hz under no-load condition.

Overcrank Shutdown

4.8.1 Check fuel level.

4.8.2 Check for proper operation of fuel pump.

4.8.3 If engine still does not start, refer to engine manufacturer’s Operator’s
Manual or Service Manual for possible engine problems.

Low Fuel Level Shutdown

4.8.1 Check fuel level.

Note: Warning light will come on when fuel level drops below 25%.
Engine will shut down only when level drops below 5%.

4.8.2 Check for leaks in fuel tank.

4.8.3 Check for Diagnostic Trouble Codes.

4.8.4 If fuel level is good, check fuel level sender and connecting wiring on
engine. Check for continuity between sender on tank and engine
control module. See wiring diagrams.

5 Factory-Installed Options

This machine may be equipped with one or more of the following factory-installed
options. To verify if any of these options are installed on your machine, contact the
WACKER Corporation at 1-800-770-0957. A nameplate listing the Model Number, Item
Number, Revision, and Serial Number is attached to each unit. Please have this
information available when contacting WACKER Corporation.

5.1 Block Heater

See Graphic: wc_gr001709

The engine block heater option includes a block heater (a) with a cord
(b). The function of the block heater is to heat the engine coolant/

engine block to improve cold-weather engine starting. Plug the cord
into a 120V power supply.

wc_tx000380gb.fm 74

Mobile Generators Factory-Installed Options

5.2 Fuel/Water Separator

See Graphic: wc_gr001705

The fuel/water separator separates water from the fuel on models with
Isuzu engines. Empty the separator water bowl (a) as needed by
opening the water bowl drain (b). The separator element should be
changed each time the fuel filter is changed—approximately every 600
hours of operation.

To change the element:

5.2.1 Loosen the element retainer (d) and remove the retainer and element
(c) from the separator head.

5.2.2 Unscrew the water bowl from the element.

5.3 Electronic Governor

See Graphic: wc_gr001714, wc_gr001715, wc_gr001716, wc_gr001717

The electronic governor option consists of an electronic module (a or
b) and an electronic actuator (c or d). The module senses rotation of

the flywheel, then sends a signal to the electronic actuator that governs
the fuel injection system. The system is designed to precisely regulate
engine rpm, and thus frequency, to within approximately 0.25%. See
electronic governor manufacturer's literature for detailed information.

wc_tx000380gb.fm 76

Mobile Generators Factory-Installed Options

5.4 LCD Strip Heater

See Graphic: wc_gr001724, wc_gr001725

The LCD strip heater option includes a thermostat module (a) and a
clear heater strip that is bonded to the LCD (b) of the ECM. The
purpose of the strip heater is to prevent the LCD from being damaged
by extremely cold temperatures. The resistance of the coiled element
of the heater is sensed by the thermostat. The resistance of the
element changes with temperature. At approximately -30°C, the
resistance value triggers the thermostat to send power to the element.
The LED (c) of the thermostat module flashes during operation.

It is important to note that the LCD strip heater is always on and thus
draws power (a very small amount) from the battery even when the unit
is not running. If the battery should fail, the heater will also fail. Be sure
to keep the battery charged when the generator is not in use.

5.5 Low Coolant Shutdown

See Graphic: wc_gr001708

The low-coolant shutdown system consists of an electronic sensor that
monitors coolant level. The sensor (a) is mounted to the radiator and
wired into the ECM. The sensor probe (b) is submerged in radiator
coolant. If the probe senses no coolant, it sends a signal to the ECM.
The ECM program includes a 10-second timer to protect from
nuisance shutdowns. If after the ten seconds coolant levels are still
sensed as being low, the ECM shuts down the engine. The ECM will
then display the “FAULT LOW WATER LEVEL”. Allow the engine to
cool before adding additional coolant.

NEVER remove the radiator cap while the engine is hot! Pressurized

WARNING

coolant can cause serious burns.

If it is necessary to open the radiator, only do so with the engine off,
and only when coolant is cool enough to touch with bare hands. Slowly
loosen the radiator cap to relieve pressure first, before removing it
completely.

Note: The sensor may be disabled by unplugging the wire harness.
This action will not shut down the machine.

5.6 Lube Level Maintainer

See Graphic: wc_gr001711, wc_gr001712, wc_gr001713

The lube level maintainer system protects the engine from low oil
levels by providing an additional 6-quart oil reservoir. Oil from the
reservoir is gravity-fed from the oil reservoir (a) through the control
valve (b) and into the engine oil pan as needed. The valve includes a
sightglass (c) through which the oil level can be seen. This oil level is
the same as that measured by the engine dipstick. A float inside the
valve detects low oil levels and opens the valve to supply the needed
oil. The system is wired to the ECM and includes a low oil shutdown in
case the oil in the reservoir is depleted. If the engine shuts down due
to low oil, the ECM will display “FAULT LOW OIL LEVEL”. Fill the
engine and the additional oil reservoir with oil before placing the
generator back into service.

Note: On machines with the Isuzu engine, the reservoir is mounted to
the enclosure door.

NOTICE: To prevent overfilling the engine with oil, place the shutoff
valve (d) in the closed position when moving or towing the generator.
Once the generator is in position, open the valve.

See Graphic: wc_gr001706, wc_gr001707

The shutters (a) are mounted to the top of the generator enclosure.
The shutters are designed to keep the engine compartment warm, thus
increasing engine temperature during cold weather operation. The
shutters are activated through a wax-pellet actuator (b) that is
connected to the generator's cooling system. As radiator coolant
warms, the wax-pellet actuator engages a linkage (c) that opens the
shutters. As the coolant cools, the shutters close.

5.8 Lockable Battery Disconnect

See Graphic: wc_gr004338

A lockable ON/OFF switch is available which disconnects the battery.
A padlock (not included) securely locks the switch in the OFF position.
If equipped, the battery disconnect switch is mounted to the upper skid
beneath the access door on either the right or left side of the machine.

NOTICE: Do not use the battery disconnect switch while the engine is
running. Damage to electrical components may occur.

5.12 Containment System

See Graphic: wc_gr002647

Overspills and leaks are captured in the containment system. The
containment system holds over 110% of the fluid contained in the
machine.

The containment system should be checked every 50 hours or 2
weeks and drained when necessary. If fluid is found in the containment
tank, trace the cause of the leak and correct.

Note: In the interests of environmental protection, place impermeable
sheeting and a container under the machine to collect the liquid which
drains off. Dispose of this liquid in accordance with environmental
protection legislation.
