The need for an international standard of measurement has been increased by
today's improved communication and transportation between countries.

This has prompted formation of modernized metrics known as the International

System of Units, officially abbreviated SI.
ONAN products appear on the world market, therefore both metric and the present

American system of units (CU) will be found in this manual.
To assist in familiarization, refer to the following terms.

The customary unit of Brake Horsepower (BHP) becomes kilowatts (kW) when
converted to S I metric units. This kW rating should not be confused with the kW

rating of the generator which will always be lower due to losses inherent with any
electrical induction device.

DESCRIPTION

GENERAL

An Onan DEH series electric generating set is a
complete unit consisting of an engine driven AC
generator, with standard and optional controls and
accessories as ordered.

ENGINE

The engine on the DEH is a Ford-Dorset
described in the engine manual. Basic measurements
and requirements will be found under
SPECIFICATIONS. For operation, maintenance and
service information, consult the Ford-Dorset manual.

AC

GENERATOR

The generator is an ONAN Type UR, 12

revolving

main rotor is attached directly to the engine flywheel,
therefore engine speed determines generator output
frequency. The 60 Hz set operates at 1800 r/min, the
50 Hz at 1500 r/min. Excitation is achieved as
foi

lows­Residual alternating durrent from the stator winding
is applied to the voltage regulator, where it is

compared with a reference voltage, rectified- and

returned to the field winding of the exciter. Current

then induced in the exciter rotor is rectified and fed

into the generator rotor. This induces a current in

generator stator which is applied to the

The only equipments discussed in this section will be

those which the operator may have reason to adjust or

inspect for service.
Terminal Board (TB) 21: Connection of wire W12 to

terminals H3, H4, H5, and H6 is made at this point, to
change reference voltage when reconnecting
generator for different voltages. Refer to Figure 1.

Voltage Regulator, Begin Spec G: Solid state unit,

consisting of printed circuit board VR21; an SCR
bridge CR21, with a commutating reactor L21 are

located in the control panel as part of the voltage
regulator system. AC output from generator is

trolled at predetermined level regardless of

con-

load;
regulation is plus or minus 2% from no load to full
load,

at 0.8 P.F.

Voltage Regulator, Prior to Spec G: Solid state unit
consisting of printed circuit board VR21.

An exciter-regulator assembly designated VR22 containing an SCR

bridge circuit and commutating reactor is mounted on the

generator end bell (see Figure 4) and works in conjunction with
VR21.

Engine Monitor: Printed circuit plug-in modules
provide the following functions:

1.

A 75 second cranking period.

2.

Approximately a 12.5-second time delay for oil

pressure buildup.

3. An external alarm contact to light afault lamp and
shut down the set for alarm conditions such as:

a. Overcrank (failed to start after cranking 75

seconds).

b. Overspeed (enginespeed reaches2100 r/min).
c. Low oil pressure 14 psi (96.5 kPa).
d.

High engine temperature 215° F (102°C).

On standard control panels, all four alarms are wired into one
common fault lamp; on units with five fault lamps, four have
shutdown alarms, the fifth (low engine temperature) lights a fault
lamp only. Refer to Table 2.

Standard Cranking Module: Limits engine cranking
time to 75 seconds. If engine fails to start after 75
seconds the engine monitor lights a fault lamp and
opens the cranking circuit.

crank time and a 10-second rest time for three ON and
two OFF cycles in 65 seconds. If engine fails to start,
after 75 seconds the engine monitor lights a fault lamp
and opens the cranking circuit. The ON and OFF
cycle times are nominal and can be adjusted at
potentiometers on the cranker module board.

Pre-Alarm:

Gives advance warning for low oil

pressure or high engine temperature. Requires two

sensors each for engine temperature and oil pressure.

INSTALLATION

GENERAL

Installations must be considered individually. Use
these instructions as a general guide. All installations
must meet regulations of state and local building
codes, fire ordinances, etc., which may affect installa­tion details. See Figure 7.

Requirements to be considered prior to installation:

1.

Level mounting surface.

2.

Adequate cooling air.

3. Adequate fresh induction air.

4.

Discharge of circulated air.

5. Discharge of exhaust gases.

6. Electrical connections.

7. Fuel installation.

8. Water supply (city water cooling).

9. Accessibility for operation and servicing.

10.

Vibration isolation.

11.

Noise levels.

LOCATION

Provide a location that is protected from the weather

and is dry, clean, dust free and well ventilated. If

practical,

Radiator set cooling air travels from the rearof the set
and is removed by a pusher fan which blows out
through the radiator. Locate the air inlet to the rear of
the set. Make the inlet opening at least IVfe-times

larger than the radiator.

Locate the cooling air outlet directly in front of the

radiator and as close as possible. The opening size
should be at least as large as the radiator
and shape of the air outlet duct should offerminimum

restriction to air flow. Use a duct of canvas or sheet

metal between the radiator and the airoutlet opening.
The duct prevents recirculation of heated air.

Provide a means of restricting the air flow in cold
weather to keep the room or compartment
temperature at a normal point.

For operation outside a building, a shelter housing
with electrically operated louvres is available as an
option.

When the generator is operating, current in the
transformers actuate the motors and open the

louvres. The louvres are held open for the duration of
the set operation, then are closed by return springs
when the set is shut down.

MOUNTING

Generator sets are mounted on a rigid skid base
which provides proper support. The engine­generator assembly is isolated from the skid base by

rubber mounts which provide adequate vibration
isolation for normal .installations. For installations
where vibration control is critical, install additional
spring-type isolators between skid base and founda­tion.

For convenience in general servicing and changing
crankcase oil, mount set on raised pedestal at least 6­inches (150 mm) high. Refer to ONAN Technical
Bulletin T-030 for further installation information.

VENTILATION

Generator sets create considerable heat which must
be removed by proper ventilation. Outdoor in­stallations rely on natural air circulation but indoor
installations need properly sized and positioned vents
for the required air flow. See SPECIFICATIONS for
the air required to operate with rated load under
normal conditions at 1800 r/m.

City water cooled sets do not use the conventional
radiator. A constantly changing water flow cools the
engine. Ventilation is seldom a problem, but sufficient
air movement and fresh air must be available to
properly cool the generator, disperse heat convected
off the engine and support combustion in the engine.

For small compartments, a duct of equal or larger area
than generator outlet is recommended to remove the
heated air from the generator air outlet to the outside
atmosphere. Limit bends and use radius type elbows
where needed. A larger, well ventilated compartment
or room does not require a hot air duct.

Installations made in a small room may require
installation of an auxiliary fan (connected to operate
only when the unit is running) of sufficient size to

assure properaircirculation and evacuation of fumes.

COOUNG

SYSTEM

Standard Radiator Cooling, uses a set mounted

radiator and engine driven pusher type fan to cool
engine water jacket. Air travels from the generator
end of the set, across the engine and but through the

radiator. An integral discharge duct adapter flange
surrounds the radiator grille.

This system reduces set enclosure airflow re­quirements and noise levels. Proper operation is
dependent on a constant supply of cooling water.The
system cannot be protected from freezing. See Figure

9.

Heat Exchanger Cooling (optional), uses a shell and
tube type heat exchanger instead of the standard

radiator and fan. Engine jacket coolant circulates
through the shell side of the heat exchanger, while

raw cooling water is pumped through the tubes.

Engine coolant and raw water do not mix. This type of

cooling separation is necessary when the raw water

contains scale forming line and other impurities.

This system reduces set enclosure airflow ahd noise

levels.

Proper operation depends upon a constant
supply of raw water for heat removal. The engine
coolant side of the system may be protected from
freezing the raw water side cannot. See Figure 8 for
typical installation.

Siandpipe Cooling (optional) substitutes a mixing
(tempering) tank for the standard radiator and fan.
Cooling watercirculating through theenginejacket is
mixed with raw water in the tank. Because raw water

flows through tho engine jacket, it must not contain

scale forming .impurities or fouling of the engine,
water will occur. Fouling results in engine
overheating and ^ostiy repair bills.

Remote Radiator Cooling (optional), substitutes a
remote mounted radiator and an electrically driven

fan,

for the set mounted components. Removal of the

radiator and fan from the set reduces set enclosure
airflow requirements and noise levels without forcing
dependence on a continuous cooling water supply.
The remote radiator system can be completely

protected against freezing.
This system must be designed to meet specific

requirements of the application.
Water Jacket Heater (optional) may be installed to

keep engine coolant warm while engine is shutdown.

It heats and circulates the coolant within the engine,
which reduces start-up time and engine wear caused

by cold starts. It is electrically operated and. ther-

mostatically controlled.

COOLING

CONNECTIONS

The radiator cooled (standard) set does not require
any external connections except as discussed under

Ventilation. Allow clearance around thesetforaccess

to service the radiator and fan belts. See Figure 7.
Heat Exchanger and Standpipe cooled sets must be

connected to a pressurized supply of cold water.
Make connections to the set with flexible pipe to
absorb vibration. On the cool water line install a
solenoid valve to shut off the flow when the set is shut
down and a. rate of flow valve to control engine
temperature. This valve can be either manual or
automatic. Actual rate of flow will depend on inlet
watertemperature.

Adjust the flow to maintain water temperature
between 165° F and 195° F (73.9° C and 90.6° C) while
viewing the water temperature gauge.

Before filling cooling system check all hardware for security. This
includes hose clamps, capscrews, fittings and connections. Use
flexible coolant lines with heat exchanger, standpipe or remote
mounting radiator.

The regular formula can be used with plain water ahd
selected antifreezes. The best protection results will

be gained by using the borate formula element with a

. permanent antifreeze.

ONAN recommends that shutoff valves be installed to
the engine side of the inlet and outlet of the coolant
filter, for ease in changing elements. Anothersugges­tion,

if so desired, a thick-walled pyrex tube can be

inserted and clamped into the line at a convenient

point to serve as a flow indicator. This flow indicator
will act in the capacity of a sight gauge to observe
general condition, possible air pockets and presence
of contaminants in the coolant flow. See Figure 10for

installation recommendations-.

Remote radiator plumbing will vary with installation.
All systems must comply with the following
conditions—

1.

Make all connections to the set and to the

radiator, with flexible pipe.

2.

Install an auxiliary circulating pump if the

horizontal distance between the engine and
pump exceeds 15-feet (4.65 m).

3. Install a hot-well system to relieve excess engine
water jacket pressure if the top of the radiator is

more than 15-feet (4.65 m) above the center-line
of the engine crankshaft.

GENERAL

WATER

FILTER

Electric generating sets can be equipped with an
optional cooling system filter (corrosion resistor).
This filter is a unit which directs coolant from the
system through a filtering and treating device. It
softens water, neutralizes acidity and protects against
corrosion by the use of a replaceable chemically
activated filtering element. In addition, the unit

con­tains a sacrificial metal plate which arrests pitting of
metals in the system by electro-chemical action.

EXERCISE

Generator sets on continuous standby service are
required to be operative at essential loads from a cold
start in a short period of time in the event of a power
outage.

This imposes severe conditions on the engine. Fric­tion of drypiston rings upon dry cylinderwallscauses
scuffing and rapid wearing. These can be relieved by
exercising thei set at least once a week for a minimum
time of 30-minutes per exercise period. Preferably,

run the set under at least 50 percent load to allow the
engine to reach normal operating temperature. This
will keep engine parts lubricated, maintain fuel prime,

prevent electrical relay contacts from oxidizing and

insure easy emergency starts. Onan automatic
transfer switches contain an optional exercise switch

GENERAL

MAINTENANCE

GENERAL

Follow a definite schedule of inspection and ser­vicing,
accurate logbook, of maintenance, servicing, and
operating time. Use the running time meter to keep a
record of operation and servicing. Service periods
outlined are recommended for normal service and
operating conditions. For continuous duty, extreme
temperature, etc., service more frequently. For in­frequent use, light duty, etc., service periods can be
lengthened accordingly. Refer to Ford^Dorset engine
manual for details of engine service and maintenance
procedures.

SPEED

Before performing any maintenance work on

the engine, generator, control panel,

Generator frequency is in direct ratio to enginespeed
which is controlled by the governor. The governor
controlling the DEH set is integral with the injector
pump.

High and low speed limit stops are set at the
ONAN testing facility and normally do not require
further adjustment, therefore if your set is ori

tinuous standby service, the governor may never

need to be touched.
If however the unit is removed for repair or the set is

used frequently, adjustment may be necessary due to

COOLANT
(Water

CORROSION

Filter)

RESISTOR

The PAF formula elements can be used with most

permanent antifreezes, but is not recommended for

use with plain water. It is necessary to drain and flush
the system thoroughly when changing from one
element formula to the other if a non-compatible
antifreeze is in use. See Figure 10 for view of the
system.

At each 300 to-500 hour interval of operation,
depending on conditions, service the coolant filter as
follows:

1.

Thoroughly clean filter body and surrounding

area.

2.

Close coolant inlet and outlet shutoff valves.

3. Remove drain plug from bottom of filter body and
drain coolant.

4.

Remove capscrews attaching filter cover to body

and remove cover (Figure 26).

5. Lift upper plate and filter element out of filter
body. Discard filter element.

6. Remove lower corrosion resistor plate and spring

from filter body.

7. Inspect and clean lower corrosion resistor plate,
buffing it to a bright finish. If plate is thin and

pliable, or has developed holes, replace it.

8. Remove and clean sump plate. Clean sump area
in filter body.

9. Install sump plate, spring, and lower corrosion
resistor plate.

10.

Install new filter element. '

11.

Position upper plate in filter body.

12.

Make certain gasket is ih good condition, then

install cover and secure with attaching

capscrews.

13.

Replace drain plug and open inlet and outlet

shutoff valves.

Initially the element should be changed after 150 hours of operation
for borate (PAF) formula filter elements.

Do not use soluble oil or other conditioners in the
cooling system. However, filter efficiency is not
affected by use of permanent type antifreeze in the
system.

the system

On an extremely dirty system, the coolant should be
drained and flushed before a new element is installed.

In a few rare cases, additional flushing and change of
filter may be necessary in order to completely purge
the system. Generator sets subject to excessive idling
or frequent start and stop cycles, or units located in
areas with dust, air contaminants, or other noxious
atmospheric conditions, will require more frequent
servicing.

After maintenance has been completed, check flow
indicator if one has been installed to see if air bubbles

(which can cause pump cavitation) are in the system.
If air is present, bleed the system by disconnecting
the filter outlet line momentarily until the coolant
flows in a solid stream.

GENERAL

ENGINE

MAINTENANCE

Refer to the engine manual furnished with the

generating set for additional details on servicing

procedures not covered by this manual. Refer to
Table 5 for general information on clearing the
electric generating set of any malfunctions which

have developed during the period of operation.

SOLENOID

In case the set does not shut down when moving Run­Stop/Reset-Remote switch to Sfop position, the stop
solenoid linkage may be out of adjustment. See
Figure 27. Adjust as follows:

1.

Remove the joint that attaches the stop solenoid

rod to injection pump arm.

2.

With the engine running, move the lever arm on

the injection pump back slowly towards radiator
just until engine stops.

3. Hold lever in this same position and adjust linkage
accordingly.

GENERATOR

There are no brushes, brush springsorcollector rings
on these generators, therefore they require very little
servicing.

Periodic inspections, to coincide with

engine oil changes, will ensure good performance.

Generator Bearing: Inspect the bearing every 1000
hours with the unit running. Apply light smear of
Molykote grease if unit appears dry.

If using the unit for "prime power," replace the
bearing every 10,000 hours or two years. If using the
set for "standby," replace the bearing every five years.

Check generator voltage. It may be necessary to
make a slight readjustment of the voltage rheostat to
obtain the preferred voltage at average

load.

INSPECTION

AND

CLEANING

When inspecting the rotating rectifier assembly,

make sure diodes are free of dust, dirt and grease.

Excessive foreign matter on these diodes and heat

sinks will cause the diodes to overheat and will result

in their failure. Blow out the assembly periodically,
with filtered, low pressure air. Also check to see that
diodes and leadwires are properly torqued. The
diodes should be torqued to 30 in. Ib. (3.4 N*m) or
finger tight plus a-quarter

turn.

Blow dust out of

control panel.

BATTERIES

Check the condition of the starting batteries at least

every two weeks. See that connections are clean and

tight. A light coating of non-conductive grease will

retard corrosion at terminals. Keep the electrolyte at
the proper level above the plates by adding distilled
water. Check specif ic gravity, recharge if below

1.280.

CONNECTIONS

(Fuel,

Exhaust,

etc.)

Operator should periodically make a complete visual
inspection of the set while running at rated

load.

Some of the things to check for are as follows:

1.

Check all fuel and oil lines for possible leakage.

2.

Inspect exhaust lines and mufflers for possible

leakage and cracks.

3. Periodicallyordaily, drain moisture from conden­sation traps.

4.

Inspect water lines and connections for leaks and

security.

5. Inspect electrical wires and connections for
security and fray damage.

If generator requires major repair or servicing, contact an authoriz-

ed Onan dealer or distributor.
