Fischer Panda
FISCHER GENERATORS have been manufactured since 1978 and are a well-known brand for first class diesel generators with especially effective sound-insulation.
Fischer has been one of the leading manufacturers in respect of quality and know-how during this period.
FISCHER, as the worldwide manufacturer of modern marine diesel generators, developed the Sailor-Silent series for
example and produced a GFK sound-insulated capsule as early as 1979 and the basis for new generator technology.
The companies Fischer and Icemaster amalgamated under the direction of Icemaster in 1988, in order to concentrate
on the development of new products. Production was moved to Paderborn.
The amalgamation of the two qualified companies led to the development of a complete new programme within a short
space of time. The aggregates developed at that time set new technological standards worldwide.
The aggregates became more efficient and powerful than other aggregates in the same nominal performance range,
because of the improved cooling. Panda generator demonstrated its superiority in several tests by renowned institutes
and magazines during the past years. The patented VCS (voltage Control System) means it can meet all demands
including motor speed. The start-booster (ASB) means Panda generators meet the highest demands in respect of
voltage stability and starting values A Panda generator, with the same drive motor, produces 15% more effective output
than the majority of conventional generators. This superiority in efficiency also ensures a fuel saving to the same extent.
The 100% water-cooled Panda Aggregate are currently manufactured in the performance range from 2 to 100 kW in
various versions. Fast running motors are preferred for performances up to approx 30 kW (Nominal speed 3000 rpm).
The heavier slow runners are preferred for the higher range. The fast running aggregates have proved themselves
many times for many uses, that they meet the demands in quality of yachts and vehicles, and offer space and weight
saving of 50% compared to slow running generators.
In addition to the Panda series, Icemaster also supply the super compact high-tech sound-insulated battery charging
aggregate from the DC/AC Panda AGT series, which is a very interesting solution for the production of mobile power.
The new HTG-alternators ensure that a charging rate of 285 amps is achieved that was scarcely thought possible for
this compact construction. This alternator replaces a separate shipboard generators (constant 230 volts AC with up to
3500 kW from the main machine)

Safety Instructions
The electrical Installations may only be carried out be trained and
tested personnel!
The generator may not be taken into use with the cover removed.
The rotating parts (belt-pulley, belts, etc) must be so covered and protected do that there is no danger to life and
body!
If a sound insulation covering must be produced at the place of installation, then well-placed signs must show that
the generator can only be switched on with a closed capsule.
All servicing-, maintenance or repair work may only carried out, when the motor is not running.
Electrical voltages above 48 volts ( battery chargers greater than 36 volts) are always dangerous to life). The rules of
the respective regional authority must be adhered to. Only an electrician may carry out installation of the electrical
connections for safety reasons.
General safety references for the enterprise of a AGT generator.
With all energized systems, with which the current is more than 50 Ampère, special safety precautions must be
made, in order to protect the environment of the components against fire.
It is to be ensured absolutely that at the battery a main switch in well accessible place is accommodated, so that with
danger of the main switches can be separated immediately. The main switch must be however also directly at the
battery installed. If this place is not well accessible, a power relay must be used instead of the main switch which can
be served manually, which can be served then if necessary from different places. The switches for the power relay
are to mark accordingly as main switches DC battery "with danger switch off!".
Cooling of the diode block.
The diode block is cooled with fresh water. A normal cooling of the diode block is therefore only possible, as long as
the cooling water supply of the generator functions duly. The cooling water supply of the generator must be so furnished therefore that by a wide dirt deflector it is guaranteed that from outside no dirt can be sucked in into the line
system. If this is not attainable, the supply must be secured by a flow switch or a negative pressure switch. The
generator must be switched off, if the cooling water supply is impair.
The temperature safety device on the diode block can be regarded only as additional safety device. The temperature
rise at the diodes is so fast that the diodes can be damaged during a unique interruption of the cooling water supply.
A safe protection from damage of the diodes is not possible by the temperature monitoring on the diode radiator box.
Thus this can take place only by means of an appropriate external monitoring of the cooling system.
ATTENTION!
Do not connect the minus pole of the starter battery to the ground of the boat because of galvanic reason.
Warning!
Never start the generator with the battery disconnected, the diodes will be damaged!
CAUTION!
Contact of the electrical contacts may be DANGER TO LIVE!
Page 5
v
CAUTION!
The AGT-generator is not allowed to be connected to an inverter (without batteries)!
The Inverter generates voltage peaks, which can destroy the rectifier diodes of the generator!
A battery must always be connected to the inverter as a capacity!
Recommended capacity at 12V ≥ 240Ah at 24V ≥ 120Ah
The screws at the electric rectifier may be pulled tight only with a torque wrench. Torque 4Nm.
The battery cable must be secured at the generator and at the batteries with appropriate safety devices.
The generator is also include into the CO2 - fire-extinguishing system.
Page 6
vi
Measures to the fire protection.
All construction units in the environment of energized parts, which carry more than 50 Amp., must be fire protectionmoderately secured.
All junction points at the energized parts must be examined regularly on heating up (infrared thermometers).
Safety Instrictions for the Handling with Batteries
These instructions must be noticed additionally to the instructions of the battery manufacturer:
• If the batteries are working, someone should be in your near area to help you in a case of emergency.
• Water and soap must be hold ready if battery acid corrode your skin.
• Wear eye protection and protective clothing. During working with the batteries don´t touch the eyes.
• If you got a acid splash on your skin or clothing grow it with much water and soap out.
• If you got acid in your eyes rinse them immediately with clear water until no cauterization is noticeable. Visit immediate a doctor.
• Don´t smoke in the near of the batteries. Avoid naked flames or open fires. In the area of batteries exists danger
of explosions.
• Pay attention that no tools fall on the battery poles, if necessary cover them.
• During the installation don´t wear a wrist watch or arm jewels, you can create under these circumstances a battery
short-circuit. Burning of the skin could be the result.
• Protect every battery contact against unintentional touch.
• Use only cyclical profoundly dischargeable batteries. Starter batteries are not appropriate. Lead-gel batteries are
commended. They are maintenance-free, profoundly dischargeable and not produce gas.
• Do not charge a frozen battery.
• Avoid a batterie short-curcuit.
• Take care of a good ventilation of the battery to drain off developing gas.
• The battery connection terminals must be checked of a tight contact at least before operating.
• The battery connection cable must be carefully mounted and checked about incorrect heating at operation with
load. The vibrating devices must be regulary checked about scour points and flaw in the isolation.

A.2.2 Components of Cooling System (raw water)
Raw water inlet
The diagram shows the supply pipes for
the generator. The connection neck for
the raw water connection is shown on the
left hand side. The cross-section of the
intake pipe should be nominally larger
than the generator connection.
Fig. A.2: Raw water inlet
Seawater impeller pump
The raw water pump is fitted with a rubber
impeller. This pump is self-inductive. If,
for example, you forget to open the sea
valve, then you must expect the impeller
to be destroyed after a short period of
time. It is recommended to store several
impellers on board as spare parts.
Fig. A.3: Raw water pump
Heat exchanger

Page 16
The Panda Generator
Page 10 Panda PMS AGT-DC 4000 - 24V - Chapter A: The Panda Generator
Ventilation valve
A siphon must be installed if the generator
sinks below the water line because of the
rocking of the boat, even if it is only for a
short period of time. A hosepipe on the
generator casing has been produced for
this. Both connecting pieces are bridged
by a formed piece of pipe.
Fig. A.5: Ventilation valve
Cooling water injector nozzle
The injection point for the marine generator water-cooled exhaust system is situated at the exhaust connection pieces The
exhaust connections must be regularly

A.2.3 Components of Cooling Systems (Freshwater)
Cooling water filler neck
The cooling water filler neck is situated at
the colling water tank and only used,
when the generator is initially started.
Since the generator is normally already filled with cooling water, these components
are only by the user, if repairs are to be
carried out.
Fig. A.7: Cooling water filler neck
Freshwater backflow
The cooling water is fed to the heat
exchanger from the cooling water tank by
means of the pipe shown in the diagram.

Internal cooling water pump
The diesel motor cooling water pump (see
arrow) aids the circulation of the internal
freshwater system.
Fig. A.10: Internal cooling water pump
Ventilation valve cooling water pump
The ventilation screw above the cooling
water pump casing may not be opened,
whilst the generator is running. If this
occurs by mistake, air will be drawn
through the opening. Extensive ventilation
of the whole system is then necessary.

A.2.4 Components of the Fuel System
External fuel pump
The Panda generator is always supplied
with an external, electrical (12 V of DC) fuel
pump. The fuel pump must be always
installed in the proximity of the tank. The
electrical connections with the lead planned
for it are before-installed at the generator.
Since the suction height and the supply
pressure are limited, it can be sometimes
possible that for reinforcement a second
pump must be installed.
Fig. A.16: External fuel pump
Connecting pieces for the fuel pipe
1. Fuel intake
2. Fuel backflow
Fig. A.17: Fuel connections
Fuel solenoid valve
The fuel solenoid valve opens automatically if „START“ is pressed on the remote
control panel“. The solenoid closes, if the
generator is switched to „OFF“ position.
It takes a few seconds before the generator
stops. If the generator does not start or
does not run smoothly (i.e. stutters), or
does not attain full speed, then the cause is
fore-mostly the solenoid.

The Panda Generator
Panda PMS AGT-DC 4000 - 24V - Chapter A: The Panda Generator Page 15
Injection nozzle
If the engine does not start after the ventilation, the fuel injection line must be deaerated.
Fig. A.19: Injection nozzle
Glow plug
The glow plug serve the pre-chamber for
the heating with cold start. The heat-treat
fixture must be operated, if the temperature of the generator is under 16°C. This
is practically with each start the case. The
heat-treat fixture may be held down also
during start and favoured the starting procedure.

A.2.5 Components of Combustion Air
Air suction openings at the sound
cover
The sound cover is provided at the upper
surface with drillings, through which the
combustion air can influx.
It must be consistently paid attention that
the generator is installed in such a way
that from no water can arrive into the proximity of these air openings.
Fig. A.21: Combustion air intake
Air suction housing
Remove the cover to look indes the housing. There is a filter element. This must
be checked from timt to time.

Oil drain hose
The Panda generator is equipped that the
engine oil can be drained over an drain
hose. The generator should be always
installed therefore that a collecting basin
can be set up deeply enough. If this is not
possible, an electrical oil drain pump must
be installed.
Note: Lubricating oil should be drained
in the warm condition!

AtTTENTION! OIL PRESSURE CONTROL!
True, the diesel motor automatically switches off when there is a lack of oil, but it is very damaging for the motor, if
the oil level drops to the lowest limit. Air can be sucked in suddenly when the boat rocks in heavy seas, if the oil
level is at a minimum. This affects the grease in the bearings. It is therefore necessary to check the oil level daily
before initially running the generator. The oil level must be topped up to the maximum level, if the level drops below
the mark between maximum und minimum levels.
2. State of Cooling Water.
The external compensation tank should be filled up to a maximum of in a cold state. It is very important that large
expansion area remains above the cooling water level.
3. Open Sea Cock for Cooling Water Intake.
For safety reasons, the seacock must be closed after the generator has been switched off. It should be re-opened
before starting the generator.
4. Check Seawater Filter.
The seawater filter must be regularly checked and cleaned. The impeller fatigue increases, if residual affects the
seawater intake.
5. Check all Hose Connections and Hose Clamps are Leakage.
Leaks at hose connections must be immediately repaired, especially the seawater impeller pump. It is certainly
possible that the seawater impeller pump will produce leaks, depending upon the situation. (This can be caused by
sand particles in the seawater etc.) In this case, immediately exchange the pump, because the dripping water will
be sprayed by the belt pulley into the sound insulated casing and can quickly cause corrosion.
6. Check all electrical Lead Terminal Contacts are Firm.
This is especially the case with the temperature switch contacts, which automatically switch off the generator in
case of faults. There is only safety if these systems are regularly checked, and these systems will protect the generator, when there is a fault.
7. Check the Motor and Generator Mounting Screws are Tight.
The mounting screws must be checked regularly to ensure the generator is safe. A visual check of these screws
must be made, when the oil level is checked.
8. Switch the Land Electricity/Generator Switch to Zero before Starting or Switch Off all the Consumers.
The generator should only be started when all the consumers have been switched off. The excitation of the generator will be suppressed, if the generator is switched off with consumers connected, left for a while, or switched on
with extra load, thus reducing the residual magnetism necessary for excitation of the generator to a minimum. In
certain circumstances, this can lead to the generator being re-excitated by means of a DC source. If the generator
does not excitate itself when starting, then excitation by means of DC must be carried out again.
9. Check the Automatic Controls Functions and Oil Pressure.
Removing a cable end from the monitoring switch carries out this control test. The generator should then automatically switch off. Please adhere to the inspection timetable (see Checklist in the appendix).

A.3.2 Starting Generator
1. If necessary, open the fuel valve.
2. If necessary, close the main battery switch.
3. Check if all the consumers have been switched off.
The consumers are switched off, before the generator is switched off. The generator is not to be started with consumers connected. If necessary, the main switch or fuse should be switched off or the consumers should be individually switched off.
4. Press „ON“ button.
If an automatic start is requested during the switching on process, the generator is started and the panel switches
to automatic mode; if there is no automatic start request, the panel switches to delay mode.
5. Press „START“ button.
Press the "START"-button for a short period. The generator is started automatically. As soon as the motor turns
over, the starter switches off automatically. It must be monitored every time it is started. The generator must be
immediately switched off if the starter is still audible after the engine revs up.
The "START"-button fulfills several functions in the different operation modes of the panel:
If the panel is in delay mode, the generator is started and the panel switches to manual mode, that means the
automatic stop functions are not carried out. If the "AGT"-generator is started manually, it must be stoped manually,
too. In this case there is no automatic stop!
In the manual mode, the generator continues to run and the panel switches to automatic mode, that means if the
last automatic start programm is dispensed with, the generator is stopped and the panel switches to delay mode; if
there is no automatic start programm, the generator is stopped and the panel switches to delay mode.
6. Check coolant flow.
Immediately after starting it must be checked whether sufficient coolant flows out at the exhaust.
7. Check electrical voltage.
In order protect the electrical system, especially the onboard batteries from being damaged, the generator voltage
must be continually monitored (Voltmeter).
An automatic voltage monitor should be installed, which switches the generator off when overvoltage or undervoltage occurs or sounds an alarm.
A.3.3 Stopping the Generator
1. The generator can only be switched off at the remote control panel by use of the "ON/OFF"switch during manual operation.
2. During automatic operation the generator can also be switched off by use of the remote control "ON/OFF"-switch or by opening the switch contact for automatic control (also see circuit
diagram).
In cases of emergency the generator can be stopped by using the decompression lever.
