DESCRIPTION
The WINCO ECV2510/2512 PTO drive generator will
provide 120/240V single phase, 60Hz electrical service
when direct-driven. The ECV2510 requires a 1000 RPM
input shaft speed and the ECV2512 requires a 1182 RPM
input shaft speed.
NOTE: The prime mover which drives the generator must
be capable of delivering approximately 2 HP per 1000
watts output from the generator. Observe input RPM
specifications.
The generator may be under chassis mounted and driven
from a truck transmission with a PTO drive installed in it.
When loss or damage is noted after delivery, segregate
the damaged material, and contact the carrier for claim
procedures.
“Concealed damage” means damage to the contents of a
package which is not evident when the package is delivered by the carrier, but which is discovered later. The
carrier or carriers are responsible for merchandise lost or
damaged in transit. The title to the goods rests with the
consignee when the goods are shipped FOB factory, and
only the consignee can legally file claims. Two years are
allowed in which to file suit after a claim is disallowed in
writing by the carrier.
This generator is a rotating armature design with compound field coil windings. Normal excitation is accomplished via the "Q" winding in the armature and a full wave
bridge rectifier. An automatic voltage regulator is installed
on the generator to maintain the correct voltage when the
unit is under load.
To reduce maintenance problems, the coupling between
the generator input shaft and rotor consists of precision
helical gearing rather than a chain link drive. The input
shaft is 1-1/8 in diameter smooth shaft with a key way and
center drilled for a roll pin. Both must be used at all times.
WINCO thoroughly tests each of these generators before
shipment. All are continuous duty rated.
IMPORTANT: THE MANUFACTURER STRONGLY
RECOMMENDS RUNNING THE GENERATOR UNDER
LOAD AT LEAST ONCE A MONTH IN ORDER TO EVAPORATE ANY ACCUMULATED MOISTURE CONDENSATION
UNPACKING
CAUTION: Equipment Damage
DO NOT invert generator during unpacking. The Gearcase contains oil which will leak out if inverted during
unpacking.
Unpack the generator as follows:
1. Remove the carton.
2. Inspect the generator carefully for freight loss or damage. If loss or damage is noted at time of delivery,
require that the person making the delivery make note
of the loss or damage on the freight bill, or sign the
consigner’s memo of the loss or damage. Contact the
carrier for claim procedures.
3. Remove the four bolts which hold down the generator
feet to the pallet.
4. Lift the generator from the pallet by means of the lifting
eye on the top of the generator.
INSTALLATION
********************
********WARNING**********
*********************
Before proceeding with the installation, be sure the drive
line and engine are disabled and cannot accidentally
operate while the generator is being installed.
Before beginning the installation process recheck the voltage
power rating and physical size and drive line rating and
speed, horsepower etc. Be certain they can handle the
intended load and are compatible with the required vehicle
equipment voltage, phase and current ratings. Plans for
installation should be prepared with proper attention to mechanical and electrical engineering detail to assure a satisfactory system installation. The information in this manual is
offered as a guide to finalizing your installation plans. The
installation sequence is summarized below:
A. Plan the installation :
1. Space required for installation and service
access.
2. Protected location, close to electrical connections.
3. Mounting frame.
4. Clear of moisture and dirt.
5. Shielded from excess heat and cold.
B. Mounting the generator system.
C. Clear, protected source of ventilation of generator.
D. Drive line aligned within 5 degrees (10 degrees max).
E. Pre-wire system check.
F. Initial system start-up.
G. Generator electrical power connections.
H. Final system check
A. PLAN THE INSTALLATION
1. Space Required. The space required should allow for
ample working room around and in back of generator.
A general rule to follow is 12 inches minimum clearance all around the unit. This allows a service person
to repair and remove generator parts in the event
service is needed. In general, all service can be
performed from the rear generator cover or the front
gear case.
7150-01
Page 2
60706-130
2. L ocation. Locate as close to electrical service as possible. This will reduce the cost of electrical and minimize
the losses in the power conductors. Position the unit to
keep clear of the drive line and exhaust runs.
3. Mounting Support. Frame loading, frame type and
strength should be taken into consideration when
installing an emergency rescue generator under a
truck.
4. Moisture and Dirt. Protection from adverse weather
conditions and road spray must be provided without
restricting adequate ventilation for cooling. All
electrical equipment should be protected from
excessive moisture. Failure to do so will result in
deterioration of the insulation and will result in short
circuits and grounds. Foreign materials such as
dust, sand, tint and abrasive materials have a
tendency to cause excessive wear, particularly the
brushes. It is important that the unit be installed in a
reasonably clean location for best service life. Careful
planning will eliminate costly rework.
5. Heat and Cold. All generators radiate considerable heat
when they are running. In addition, these units are
generally mounted in a somewhat restricted location
which precludes natural cooling. Allow space for cooling air to sweep across the generator shell. It is important that the temperature of the ambient air around the
unit not exceed 105 degrees Fahrenheit while operating. Additional cooling louvers or fans may be necessary if adequate cooling flow is not naturally provided.
B. MOUNTING THE GENERATOR SYSTEM
The generator should be bolted solid to a heavy steel
cross channel or plate. It is recommended that the
generator be mounted on a steel sub-frame which
facilitates easy removal of the generator for better service
access to the chassis or for generator repair.
Shock mounting the generator or mounting frame is
generally not recommended do to possible harmonic
vibration, drive misalignment and mounting stress.
C. VENTILATION OF GENERATOR
This is an air cooled generator. This unit is equipped
with a suction fan to cool the armature and field coils.
Therefore it will be necessary to insure that the hot air
discharge plume gets out of the mounting area.
D. DRIVE LINE AND LUBRICATION
Check gear case oil level. Case should be filled with oil
to plug marked “OIL LEVEL.” Fill or remove oil as required.
NOTE: EITHER TOO LITTLE OR TOO MUCH OIL CAN
HARM THE EQUIPMENT.
Make sure the drive shaft (tumbling bar) is assembled with
its universal joint knuckles “synchronized,” as illustrated in. If
knuckles are not synchronized, the bar will chatter when
rotating, which will cause the generator output voltage to
flicker.
See “Lubrication” portion of Maintenance for oil specifications.
Page 360706-130
7150-01
The PTO drive shaft should be maintained in as straight a line
as possible. Install the generator so the drive line is aligned to
within 5 degrees (10 degrees Max). The 2510/2512 PTO units
will require about 50 Hp to maintain full output, be sure that
the auxiliary drive on the vehicle transmission and the gear
reduction box is capable of the expected mechanical load. It
is generally recommended that the drive shaft be balanced to
minimize drive line vibration and stress. Make sure no binding
exists in generator or gear box. If binding is found, locate the
cause and correct it before proceeding
*****Notice *****
If for any reason during the check-out procedure the
voltage and frequency are not correct, stop the engine and
refer to the troubleshooting procedures.
After verifying the voltage and frequency are correct, prepare
for final wiring of the generator by disabling the drive system
and or engine. The generator can now be connected to the
load circuits.
E. PRE-WIRE SYSTEM CHECK:
WARNING: Personal Injury
When working on or around these generators, do not wear
loose fitting clothing or any articles that may get caught in
moving parts.
Before wiring the generator to the distribution load circuits,
the installation and operation of the drive system and
generator should be checked to insure proper drive line,
engine and generator operation.
Use the following check List to verify correct installation
before starting the engine:
1. Drive line straight and tight.
2. Unit mounting base and hardware solid and bolts
properly torqued.
3. Ventilation clear and protected.
4. Clearance on all sides and service access on both
ends
5. Generator output leads protected from grounding.
After completing the above checklist, the generator is ready
for the initial start-up test.
F. INITIAL START AND TEST PROCEDURE
CAUTION:
Make sure that all tumbling bar lock pins are engaged and
that all safety shields are in place before operating the
PTO generator.
1. See vehicle manufacturers instructions for operating
procedures. The generator should be turning at
specified rpm and producing correct voltage and
frequency. If the generator fails to operate as specified, stop the engine and refer to the trouble shooting
section of this manual.
2. With the engine running smoothly, and at the desired
speed, check the no-load voltage and frequency.
Generator leads G1 to G3, should read 240 Volts
nominal(240 TO 255 volts). Leads G1 to GN, and G3 to
GN both should read a nominal 120 volts(120 to 127
volts) at 60 Hz. It may be necessary to adjust the
voltage regulator to obtain the proper voltage. The
voltage regulator is located on the left hand side of the
generator end cover. Final voltage adjustments must
be done on the voltage regulator. The regulator may
not effect the no-load voltage to any degree.
G. GENERATOR ELECTRICAL POWER CONNECTIONS
ALL wiring should be done by a licensed electrician, and
should conform to the national electrical code and with state
and local regulations.
The generator power output leads are marked G1(A & B) ,
G3(A & B) and GN(A & B). We use parallel leads from the
generator to reduce the wire size and make them eaiser to
handle. The A & B wires are always paired together.
A main line circuit breaker must be installed in the load
distrubution panel on the vehicle. The G1 and G3 wires are
routed to the mainline circuit breaker in the distribution panel.
The neutral lead GN is run to the neutral terminal in the
distribution panel.
Note! Most codes require that the neutral conductor be
“bonded”’ (grounded directly to the frame of the generator).
Check local codes to insure compliance. Refer to the national
electrical code NEC for portable/ mobile equipment. No
further electrical connections are required.
The load current carrying wires must be sized to handle
the maximum load current without excessive voltage drop.
By NEC code, conductors must be heavy enough to handle
the full current rating of the main line circuit-breaker (or
fuse) in the load distribution panel protecting the conductors.
All wires should be installed in rigid or flexible conduit.
Because of the many different types of wiring service,
feeder, and distribution panels used on rescue equipment,
no specific wiring instructions can be provided.
*************
*****WARNING******
************
If auxiliary (shore/commercial) power may also be connected to the load for demonstration, training or alternate
source power, an isolation switch must be installed. An
isolation switch will prevent feed back of commercial power
into the generator or generator power into commercial line.
When the load is connected to the generator there must be
absolutely no feedback from the generator to the power line
or from the power line to the generator during any operating
condition. When correctly connected, the design of the wiring
control system prevents an possibility of feedback. Improper
installation can create a serious hazard that could result in
equipment damage, serious personal injury or death.
7150-01
Page 4
60706-130
H. FINAL SYSTEM CHECK
1. Recheck voltages at mainline circuit breaker. Voltages
should match readings taken at the pre-wire checkout.If problems are noted, consult troubleshooting
section or factory.
2. Turn on the mainline circuit breaker.
3. Turn on each load individually first, to insure that each
load will work properly.
4. Turn on all the loads and recheck voltages. It may be
necessary at this time to adjust the voltage using the
voltage regulator mounted on the generator end cover to
obtain the proper full load voltage.
5. Turn off all the loads and make sure that the no-load
voltage has stayed within the proper range.
6. If all voltages and frequencies stay within the proper
range, this completes your initial start up procedure.
OPERATION
Since the generator is self excited and externally regulated,
there is no need for operational controls for the generator.
Once the regulator is set it should never have to be
adjusted. The vehicle manufacturer will provide operation
manual for the governor operation and control panel
operation.
MAINTENANCE
is recommended that the generator be operated at least
monthly under normal loads to familiarize operators with the
procedures and controls as well as to dry out any accumulated condensation or other moisture in the generator electrical windings. The maintenance and service attention invested will insure getting the peak performence that was
designed into the unit.
Routine preventive maintenance minimizes costly repairs
and generator down-time. Before each use, inspect the
generator: gear case oil level should be correct, cooling
vents and screens should be clear, and generator mounting hardware should be tight. Clean and inspect the
generator after storing it for long periods, and after using it
in extremely dusty conditions or in severe weather, such as
rain or blowing snow.
Generator Maintenance
A. Brushes
Under ordinary circumstances, brushes will operate for extremely long periods without requiring replacement. They
should be inspected after the first 500 hours of operation, and
after every 200 hours of operation thereafter. Remove brushes
one at a time and check for length; be sure that each moves
freely in the brush holder. Brushes should be replaced when
worn down to 3/8”. Replace brushes in complete sets, never
singly. When replacing brushes, be careful to reconnect the
lead wires properly.
General Information
The main components of the generator are: armature, field
coils, cooling fan, brushes, brush holder assembly, end
brackets, rectifier and voltage regulator. Before performing
any maintenance on the generator, isolate and/or disable the
drive system so the unit can not be accidentally started while
being repaired.
The troubleshooting chart lists various symptoms of poor
generator operation with possible causes and the appropriate corrective action. You will need a volt-ohm meter or
test light to check some of the causes. For some of the
other causes you will need to check generator speed. To
check generator speed you can use a frequency meter, a
tachometer, or a 120V-60Hz electric clock and a correctly
operating wrist watch. (Run the electric clock on generator
power and compare the clock’s second hand movement
with that of the wrist watch. They should run at the same
speed. If clock runs faster, generator speed is too high,
and vice versa.)
CAUTION: Equipment Damage
Most electrical equipment in North America operates
satisfactorily at frequencies between 59 and 61 Hz (cycles
per second.) Operating the generator at frequencies
outside that range may cause damage to the generator
and/or to electrical equipment driven by the generator.
Periodical Maintenance
Service/maintenance items include periodic external physical inspection for missing hardware or damage to mounting
or drive system and checking the oil level in the gear case. It
Page 560706-130
Poor contact (or “skipping”) between brush and slip ring is
caused by oil and grit, flint, or other hard substance on the
brush, or by the brush not being properly shaped to fit the slip
rings. Remedy these defects by fitting the brushes to the slipring curvature. Place # 00 sandpaper under the brushes with
the abrasive side to the brushes, and work it back and forth
until the brushes are the same shape as the slip-rings.
B. Slip rings
The four continuous copper rings located on the end of the
armature are the generator output slip rings. For proper
generator output, the surface of the slip rings must have a
smooth, shiny, highly polished finish. Normal brush
seating will transfer a shiny black finish that will seat the
copper surface. This finish should not be removed unless
it becomes dull or begins to build up. Under sustained
use, it is advisable to check and if necessary, polish the
ring surfaces with a crocus cloth to maintain the smooth
finish.
C. E lectrical Testing
Testing generator fields for opens and grounds.
1. Disconnect field leads from rectifier.
2. Set multimeter to read resistance, and connect the meter
leads to the field leads. If field is open, meter will read
infinite resistance (very high ohms). Repair or replace field
if it is open. Typical resistance for these fields vary from
17.1 to 18.8 ohms.
3. Leaving one meter lead connected to the field, connect the
other meter lead to the field shell. If meter indicates
7150-01
continuity (any reading -should be infinite resistance). The
field is grounded and should be repaired or replaced. To
determine which of the fields is grounded, cut the connec
tor between the two coils and retest to determine which
coil has the low resistance path.
4. Disconnect field leads (F1 & F2) from regulator.
5. Set multimeter to read resistance, and connect the meter
leads to the field leads. If field is open, meter will read
infinite resistance (very high ohms). Repair or replace
field if it is open. Typical resistance for these fields vary
from 11.2 to 12.1 ohms.
6. Leaving one meter lead connected to the field, connect the
other meter lead to the field shell. If meter indicates
continuity (any reading -should be infinite resistance) the
field is grounded and should be repaired or replaced. To
determine which of the fields is grounded, cut the connec
tor between the two coils and retest to determine which
coil has the low resistance path.
1. Remove all brushes.
2. Ground fault test - set multimeter to read high resistance
(meg-ohms).Holding one meter lead against a clean spot
on the armature shaft, touch the other lead to each of the
slip rings (one at a time) while observing the meter. If
meter indicates continuity (any reading lower than one
meg- ohm), the armature is grounded. Dirt between the
slip rings and on the insulator surface can cause grounding. If grounding was indicated, carefully clean all dirt off
the slip rings and their insulators and then recheck it.
Replace the armature if it is grounded and unrepairable.
3. Open Test. Set meter to read low resistance (R x 1
ohms). Holding one meter lead on surface of slip ring
No. 1, touch other meter lead to surface of slip ring No.
2 while observing the meter. Meter should indicate
continuity (low resistance - less than one ohm is
typical). If the meter indicates open circuit (infinite
resistance) part of armature winding is open. This may
be caused by a repairable defect in the connection at
the slip ring, however generally an open armature will
have to be replaced. Continue reading the continuity
between slip ring No. 2 to No. 3 and No.2 and No.4. All
the slip rings should have continuity to slip ring number
2, the neutral ring.
Testing Rectifiers
The field excitation is supplied through a full wave bridge
rectifier. This type of rectifier has four terminals, two AC, a
DC positive and a DC negative.
A rectifier may be tested in the following manner:
1. Disconnect all leads from rectifier.
2. Connect the red ohmmeter lead to the positive DC (+)
terminal.
3. Connect the black lead to each of the AC terminals in turn.
Either a high or low resistance reading will be obtained.
Testing the Armature for Opens and Grounds
7150-01
Page 6
60706-130
4. Reverse the meter leads, (black lead to the DC POS (+)
and red to the AC terminals, each in turn. An opposite
reading should be observed.
The drive shaft (tumbling bar) requires greasing. Keep the
universal joints in the coupling shaft free from grease and dirt
buildup.
5. Connect the red ohmmeter lead to the negative DC (-)
terminal.
6. Connect the black lead to each of the AC terminals in turn.
Either a high or low resistance reading will be obtained.
7. Reverse the meter leads, (black lead to the DC NEG (-) and
red to the AC terminals, each in turn. An opposite reading
should be observed.
8. Check each terminal to the case. An open circuit (very high
resistance) reading should be observed. A battery pow
ered test light is used. Follow the same procedures
described above. A good diode element will allow current
to pass to the light in the test lamp when the leads are
connected in the forward direction.
9. If the rectifier fails any of the above tests, it should be
considered defective and replaced.
Condenser Testing
Condensers are built into the generator circuit to minimize
radio interference during operation. If a condenser shorts
out, it will also short out the generator output. To determine
whether a condenser is shorted, stop the generator and
disconnect the condenser lead wire from the brush holder.
Using a multimeter on the R x 100 scale, check the resistance of the condenser. Normal response is a sharp swing
of the meter towards low resistance and then a steady rise
towards high resistance (open circuit). If the capacitor is
shorted it will show as a constant low resistance.
Otherwise, restart the generator without the capacitor connected to recheck the generator for output. If the generator then
provides power, the condenser was at fault and should be
replaced. (If the generator doesn't provide power, the problem
was not caused by that condenser, reconnect the lead wire).
NOTE:
Do not over lubricate the universal joints.
Check the generator gear case oil level before each use of
the generator. Maintain the oil level at oil level plug height.
(See page 3 for oil level plug location.) The generator is
shipped with lubricant in the gear case. Specifications for
gear case lubricant are:
API Service: GL-5
Grade: SAE 85W-9O-140
Amount: 1 pint
The following kinds of oil are recommended for use in the
generator gear case: Mobil SAE 85W90-140 API Service GL5, Sunoco/DX XL80W90-140 Kendal Three Star 85W-140,
Amoco 85W140 or equivalent.
CAUTION: Equipment Damage
Do not overfill generator gear case. Overfilling causes
overheating and oil seal failure.
Change the oil at least once every six months. Change it
more often if you use the generator in bad weather. Use the
following procedure to change generator gear case oil:
1. Remove gear case breather. Soak breather in cleaning
solvent, then allow it to dry.
2. Remove oil level check plug.
3. Remove the oil drain plug, drain the oil into a clean oil
resistant container, 1 quart or larger. Check the oil for
metal. Fine metal dust in the oil does not indicate
trouble, but metal chips do. Dismantle the gear case and
look for damaged gears if you find metal chips in the oil.
If these tests have not located the trouble, remove the
armature and have it tested for opens, shorts, and grounds
on a growler.
4. Lubrication
The generator bearings are factory lubricated and sealed,
and require no further lubrication.
The generator input shaft should be cleaned and lubricated
with a thin film of grease before installing the drive shaft and
each time it is removed.
4. Replace the oil drain plug. Refill the gear case through
the breather port with new oil of the recommended type.
Fill the case up to oil level check plug height. (It will take
about 1 pint.)
5. Replace the oil level check plug.
6. Replace the breather.
