Fischer Panda 4000s SC Generator Set

⚠ Capacitors must be discharged before touching.

Tools: multimeter with capacitor measuring

1. Ensure capacitors are discharged before touching.
2. Visually check for leaking dielectric or capacitor becoming longer.
3. Set multimeter to pass; connect test prods to both capacitor contacts.
4. Observe short beep when charging; reverse poles and observe short beep again.
5. If steady sound or no sound is heard, capacitor is defective and must be replaced.
6. Use capacity measuring instrument to confirm full capacity; replace capacitors not achieving imprinted capacity.

Tools: voltmeter

1. Guarantee that connection to the electrical system is interrupted.
2. Remove all conductors in the power terminal box of the generator.
3. Connect starter battery to generator.
4. Start the generator.
5. Measure voltage between phase(s) and N with a voltmeter.
6. If measured values are substantially below Table E.2.1 values, accept coil damage.

⚠ Never work at the electrical cabinet when the generator is running.

⚠ Do not contact the capacitor before it is discharged.

Tools: isolated screwdriver

1. Switch off generator.
2. Disconnect starter battery.
3. Open generator power terminal box and remove caps.
4. Short circuit the two capacitor contacts using the cone end of an isolated screwdriver.

⚠ Do not disconnect the battery during operation.

1. Connect positive battery cable directly to solenoid switch of starter; use prepared protective tube.
2. Connect negative battery cable to connection point at engine foot.
3. Install a right-sized fuse in positive battery line as close as possible to battery, maximum 12 inch or 300 mm.
4. Use multi-core stranded wire only; protect cable from heat, vibration and chafing.
5. Check battery cable after installation for possible damage.

⚠ Electrical voltages above 48 volts are dangerous to life.

Tools: voltmeter

1. Switch off all on-board electrical devices.
2. Start the generator.
3. Measure AC voltage between generator housing and AC-Control box.
4. Measure AC voltage between generator housing and ground.
5. Measured voltage must not exceed 50 mV.

1. Fill external cooling water expansion tank with coolant; maximum fill level is max mark; open cover temporarily; keep at least 1/3 coolant during filling.
2. When coolant level no longer drops, disconnect the oil pressure switch.
3. Turn remote control panel on and let coolant pump run for at least 10 minutes.
4. Turn remote control panel off, reconnect oil pressure switch, fill expansion tank to max and close tank.

⚠ Charged capacitors can be lethal.

⚠ Never check capacitors while the generator motor is running.

Tools: multimeter with capacitor measuring, insulated screwdriver, discharge reactor 5-10kOhm

1. Switch off generator and remove starter battery.
2. Open the AC-Control Box.
3. Bridge capacitor contacts with insulated screwdriver to discharge.
4. Measure capacity with multimeter set to capacitor measuring.
5. Check all capacitors in the electrical cabinet.

⚠ Battery gases are explosive; keep sparks and naked flames away.

1. Remove sealing caps.
2. If testers are present, electrolyte level should reach their base.
3. Without testers, level should be 10-15 mm above top of plates.
4. Top up with distilled water if necessary.
5. Screw sealing caps back in.

1. Close the water cock.
2. Release raw water filter from dirt.
3. Beating the filter basket is mostly sufficient.
4. If water seeps through cover, do not seal with adhesive; find cause; replace sealing ring if necessary.

⚠ Lubricating oil should be drained in warm condition.

Tools: spanners, hand pump

1. Open oil drain screw; use a second wrench for countering.
2. Drain oil through oil drain hose; if impossible, use a hand pump.
3. Close oil drain screw again.
4. Open oil filler neck cap.
5. Refill new engine oil.
6. Wait before measuring oil level; oil must settle in the sump.
7. Check oil level with dipstick; level may not exceed Max; 2/3 level recommended.

⚠ A clogged filter causes decreased power output.

1. Clamp the inlet before exchanging the filter.
2. Remove hoses from the used filter.
3. Fasten hoses to the new filter; arrow on filter housing indicates fuel flow direction.

1. Before first start, turn engine once by hand.
2. Change engine oil and engine oil filters.
3. Reintegrate impeller of cooling water pump and check pump for leakage.
4. Charge starter battery, connect cables and check battery voltage.
5. Start generator and check basic adjustments such as voltage and speed regulation.
6. Check all switching off devices for function by operational procedures.
