4.1 Remove Shipping

Dunnage And Parts

^ WARNING

Depending on model, approximate weight of the generator is 269 - 674 kg (592 - 1485 lbs)

Do not position feet around or under pallet.

1. Remove crate material from pallet.

2. Remove all shipping bands, wires and loose parts from around generator.

4.2 Remove Generator

From Pallet

1. Attach hitch to generator frame.

2. Roll generator off of pallet onto oor.

3. Install PTO driveline.

4.3 Driveline Dimension

A PTO driveline is supplied with the machine.

To accompany the variety of hitch geometry available today, the driveline can be too long for most machines or too short for others. It is very important that the driveline be free to telescope

but not to bottom out when going through its working range. If the driveline bottoms out, the bearings on both the machine and tractor PTO shaft will be overloaded and fail in a short time.

1. To determine the proper length of the

driveline, follow this procedure:

a. Clear the area of all bystanders.

b. Attach generator to tractor (see section

5.3) but do not attach driveline.

c. Measure dimension between locking

grooves on tractor PTO shaft and

machine input shaft.

d. Measure the same dimensions on the

compressed driveline.

e. If compressed driveline dimension

exceeds the machine dimension, driveline will have to be cut.

2. When cutting the driveline, follow this procedure:

a. Subtract machine dimension (A) from

uncut driveline dimension (B) or (B-A). This dimension determines how much

too long the driveline is.

b. Add another 1 inch (25 mm) to the

dimension to be sure it doesn’t bottom out, to determine (C) the cut off dimension.

c. Use a hacksaw to cut dimension (C) from

both ends. Cut both plastic tubes and metal cores.

d. Use a le to remove burrs from edges

that were cut.

e. Assemble the 2 ends of the shaft.

f. Make sure shaft can telescope freely. If it

does not, separate the 2 parts and inspect for burrs or cuttings on shaft ends. Be sure it telescopes freely before installing.

5 OPERATION

5.1 Preparation For Use

Although the Generator has been carefully inspected and checked prior to shipment from

manufacturer, it is recommended that the unit be thoroughly inspected.

Check all bolts for tightness and remove all shipping tags, bags, skids, and blocking. Remove any masking materials afxed during painting.

Inspect the tractor and any accessory equipment

to verify that nameplates and all safety warning, caution signs and decals provided with the

equipment are in place and clearly visible.

Visually inspect the unit before each start up. Check for loose or missing parts and any damage

that may have occurred during moving or shipping.

Review all tractor pre-start instructions, and ensure

that all recommended steps and procedures have

been followed.

The generator trailer does not have a suspension. Limit speeds to less than 20 kph (12 mph) to minimize the risk of rollover.

5.6 Operating The Generator

^ WARNING

Entanglement in a rotating driveline can cause serious injury or death.

Keep tractor shields and driveline shields in place at all times. DO NOT operate without driveline guards.

DO NOT wear loose tting clothing.

^ WARNING

Never operate tractor when other people are in the vicinity.

Do not allow riders on tractor.

^ WARNING

Prevent serious injury or death caused by unexpected movement:

5.6.1 Initial Start-Up

1. Connect the power cable to the generator and to the transfer switch.

2. Start the tractor and allow it to warm up.

3. With the engine idling, engage the PTO drive.

4. Adjust throttle until the volts on DisplayMaster1 display 120 VAC (single phase).

5. Turn on the main breaker on the generator.

6. Operate the transfer switch so that the load is transferred to the generator.

1. Park tractor on a level surface.

2. Engage tractor park brake.

3. Disengage PTO.

4. Shut off engine and remove key.

5.6.2 Monitoring The Load

5.6.3 Shutting Down The

Generator

Plan when to change over to generator power. Ideally, the transfer should take place when the system demand is at its lowest. If a big motor can come on stream, change over to generator power before it does so when the load is lesser.

The generator has sufcient capacity to handle rush current (higher demand) during motor start

up, so it is permissible to operate temporarily at

overload. However, only allow the generator to do so for short periods of time (less than a minute). Carefully monitor the tractor speed settings when the load changes and adjust the throttle to keep the generator operating at 120 VAC (single phase).

NOTICE

Risk of generator damage. Avoid running the generator at overload for excessive periods of time. Doing so can damage the generator and void the warranty.

NOTICE

Follow the shut down sequence to minimize the risk of damage to the generator or associated equipment.

1. Switch off the electrical load or allow it to drop to minimum.

2. If possible, operate the transfer switch to

transfer the load back to utility power.

3. Turn generator main breaker off.

4. Drop the tractor speed to idle.

5. Disengage the PTO drive. Allow the PTO shaft to gradually come to a stop.

6. Shut off tractor engine and remove key.

7. Disconnect the PTO driveline from tractor.

8. Place the mount on the trailer tongue in the upright position and place PTO driveline on

support.

9. Tow unit back to storage.

10. See Storing Generator in this section if

generator will not be used for some time.

5.6.4 Storing The Generator

1. Wipe down the unit using a clean rag and water, or a cleaning solvent.

2. Inspect the air louvers and make sure that they are not obstructed. The generator requires a

ow of cooling air. Clean them as necessary.

3. With a rag soaked in cleaning solvent, clean

the splines on both ends of the connecting drive shaft, on the generator driveline, and on the tractor.

4. Inspect all splines on the driveshaft, the generator, and the tractor for signs of damage

or wear. Repair any damage or wear as soon

as possible.

5. Apply a light coat of lithium waterproof grease to the surfaces of the connecting driveshaft splines.

6. Examine the universal joints for signs of wear

or damage. Repair or replace any worn or

damaged part.

7. Using the grease gun, lubricate each universal joint.

8. Inspect the level of the lubricant in the gearcase.

Top off as needed with gear lubricant.

9. Verify the tire pressure and adjust as necessary. Check the sidewall of the tires for

the recommended pressure.

10. Inspect the generator to look for damage to the generator. If any damage is found, avoid using the generator and report the damage to your Baumalight representative.

11. Check all fasteners and make sure they are properly tightened. This includes the bolts that attach the generator to the trailer, the bolts that attach the guard to the gearcase, and the bolts that attach the tongue to the trailer.

12. Cover generator and store in a clean, dry place.

6 SERVICE AND MAINTENANCE

6.1 Service

6.1.1 Electrical Tests

Continuity and Resistance Test

The generator has four components that can be

checked using an ohmmeter:

• Exciter stator

• Exciter rotor

• Main stator

• Main rotor

Each of these components is composed of various windings forming a complete electrical path of relatively low resistance. Using an ohmmeter,

measure the loop resistance of each component.

Contact Baumalight for specic values for your

machine.

Note: Very small resistance values require precision equipment to make accurate measurements; however, a standard ohmmeter will provide a good indication of winding continuity.

Diode Testing

Note: Stop tractor engine before performing this

procedure.

5. Repeat the procedure using the other diode terminal post.

When the positive test probe is connected to

the diode’s anode and the negative test probe is connected to the diode’s cathode (forward biased), the diode will switch on and conduct electricity. This is observed by a low resistance reading when using an ohmmeter or the lighting of the bulb when using a battery light continuity tester. Reversing the test leads (reverse biased) will result in the diode switching off and no electricity will be conducted.

The results of these tests should indicate one of three conditions:

Good diode: Will have a much greater resistance in one direction than the other. Typical reverse

biased resistance will be less than 10 ohms. The battery light tester will have the light “on” in one direction and “off” in the other.

Shorted condition: Ohmmeter reading will be zero, or very low in both directions. The continuity tester will have light “on” in both directions.

Open condition: Ohmmeter will have a maximum (innity) reading in both directions. Continuity tester light will be off in both directions.

1. Remove the two main rotor leads and the threeexciter rotor leads from the rectier assembly. The rectier assembly is now electrically

isolated from the generator. The diodes remain mounted and the diode leads remain connected to the terminal posts.

2. Using an ohmmeter or a battery light continuity tester, place one test probe on the diode lead terminal post.

3. In succession, touch the other test probe to the lead screw hole in each heat sink.

4. Reverse the probes and repeat the procedure. You have now tested the three diodes connected to this terminal post in both the forward and

reverse direction.

Diode failure after a 25-hour “run-in” period is generally traceable to external causes such as a lightning strike, reverse current, line voltage spikes, and the like. All 6 diodes are essentially in

the same circuit.

Since determining the remaining life on the diodes

when one fails is difcult, replace the entire rectier

assembly, rather than individual diodes, to avoid possible continued failure.

6.1.2 Automatic Voltage Regulator Operational Test

1. Connect the test setup as shown in Figure 1. Do not apply power. Insure that the light bulbs are 120 volts, and less than 100 watts.

2. Adjust the regulator VAR and/or remote VAR and the STABILITY ADJUST to maximum CCW

3. Apply 240 volts, 50/60 Hz power to the

regulator. The light bulbs should illuminate.

4. Slowly adjust the regulator VAR control CW.

At the regulation point, the light bulbs should extinguish. Small adjustments above and below this level should cause the light bulbs to go off and on. Note that the light bulbs go on

and off rapidly.

5. Rotate the STABILITY ADJUST fully CW. Now

adjust the regulator VAR above and below the

regulation point. The light bulbs should still go

off and on, but the transition from off to on (and vice versa) should be much slower than in “d”

above.

6.1.3 Voltage Regulator Adjustment

Voltage Adjust

The screwdriver adjustable potentiometer adjusts the generator output voltage. Adjustment clockwise

increases the generator output voltage.

Stability Adjust

System stability is the ability of the generator to respond to load transients. Decreasing the stability

makes the generator less sluggish and faster to

respond to toad transients. If the stability of the

regulator is decreased too much, the generator will

tend to hunt under steady state conditions.

The screwdriver adjustable potentiometer adjusts the system stability. Adjustment clockwise

increases the stability. Increasing the stability increases the response time of the generator. Conversely, decreasing the stability decreases the response time of the generator.

V/HZ Roll-Off Frequency Selection

The roll off point is the frequency where the

generator voltage starts to decrease. This reduces

the Kilowatt load to the engine, which allows

the engine to recover in speed under any load

transient condition. Use jumper to select 50 HZ or 60 Hz. The screwdriver adjustable potentiometer sets the roll-off frequency from 54-61 Hz in the 60 Hz setting or from 45-51 Hz inthe 50 Hz setting.

The SE350 has the roll-off point preset to 58 Hz in the 60 Hz mode and 48 Hz in the 50 Hzmode. To change the roll-off point, adjust engine speed to the desired rated speed. (50 or 60 Hz). Set the voltage to the desired setting at rated speed. Adjust engine speed to the desired roll-off point. Turn the potentiometer counterclockwise until the voltage

starts to drop off. Then adjust the potentiometer

clockwise until the voltage returns to rated voltage. Re-adjust engine speed to rated speed.

3. Remove drain plug (B).

4. Drain oil and install plug.

5. Remove ll/check plug (A).

6. Add synthetic 75-90W gear oil until oil comes out of hole.

7. Replace ll/check plug.

Severe service for the QC Series PTO Generator includes the following:

• More than 100 hours of continuous use in a month.

• Use outdoors for extended periods in extreme

weather (dust, high heat, cold, or wet weather).

If the QC Series PTO Generator is subject to severe

service, Baumalight recommends thoroughly

cleaning and inspecting the QC Series PTO

Generator. If you suspect that there is damage,

have the QC Series PTO Generator inspected by

your Baumalight representative.

6.2.5 Maintaining The Permanent Magnets

If the generator is not used for a long time, it is possible that the permanent magnets that provide

the magnetic eld for excitation of the eld coil will lose their magnetism and the generator will not be able to produce electrical power.

To keep the magnets in good working order, you

must run the generator under load for at least an

hour once every six months.

See Restoring Residual Magnetism in this section,

if your generator loses magnetism.

6.2.6 Restoring Residual Magnetism

NOTICE

Risk of generator damage. Only attempt this procedure if you are trained to do so. If in doubt, contact your Baumalight representative.

and sensing input, the AVR will go to full conduction of its power rectier (SCR). With only 120 volts input power, the AVR will only force at half of 105 VDC or 52.5 VDC.

3. With 52.5 VDC imposed upon a 24.5 ohm eld, maximum excitation current will be in the area of 2.1 to 2.2 amperes, which is 4.5 times the exciting current imposed on the eld with a 12 VDC ashing source. 2.2 amperes is much lower than the SE350’s rated continuous current of 3.5 amperes, thus this procedure will not pose a threat to the regulator so long as the exciter eld resistance is 15 Ohms or

higher.

Note: You will need a 120 volt, two prong power cord with ag terminals crimped on the ends to

perform this procedure.

Place 120 VAC for about 2 to 3 seconds across SE350 power input terminals #3 & #4 while the unit was at rest. The basis for this procedure is:

1. The SE350 AVR requires approximately 240 VAC for both input power and sensing across input terminals #3 and #4. With 240 VAC input, maximum forcing voltage is 105 VDC. Maximum forcing current - for 1 minute is 5 amperes. Maximum continuous running current rating of this regulator is 3.5 amperes.

2. MAGNAPLUS exciter elds have a nominal resistance of 24.5 ohms. With 120 volts AC (½ rated voltage) imposed on the AVR power
