Fischer Panda
FISCHER GENERATORS have been manufactured since 1978 and are a well-known brand for first class diesel gene-
rators 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)

Diesel engine exhaust and some of its constituents
are known to the State of California to cause cancer,
birth defects, and other reproductive harm.
Attention, Important Directions regarding Operation!
1. The installation certificate must be completed when taken into use, and certified by a signature.
2. The installation certificate must be despatched within two weeks of use to ICEMASTER.
3. The official guaranty confirmation will be completed by ICEMASTER after receipt and sent to the customer.
4. A guaranty must be shown to make any claims.
Claims against the guaranty will not be accepted of the above said instructions are not, or only partially, carried out.
Manufacturer declaration in terms of the machine guideline 98/37/EG .
The generator is in such a way developed that all assembly groups correspond to the CE guidelines. If machine gui-
deline 98/37/EG is applicable, then it is forbidden to bring the generator into operation until it has been determined
that the system into which the generator is to be installed in also corresponds to the regulations of the machine gui-
deline 98/37/EG. This concerns among other things the exhaust system, cooling system and the electrical installa-
tion.
The evaluation of the "protection against contact" can only be accomplished in connection with the respective
system. Likewise among other things responsibility for correct electrical connections, a safe ground wire connection,
foreign body and humidity protection, protection against humidity due to excessive condensation as well as the over-
heating through appropriate and inappropriate use in its installed state on the respective machine lies within the
responsibility of those who undertake installation of the generator in the system.
Use the advantages of the customer registration:
• Thus you receive to extended product informations, which are sometimes safety-relevant
• you receive, if necessarily free Upgrades
Far advantages:
By your full information Fischer Panda technicians can give you fast assistance, since 90% of the disturbances result
from errors in the periphery.
Problems due to errors in the installation can be recognized in the apron.

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 furnis-
hed 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!

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.

vi
Measures to the fire protection.
All construction units in the environment of energized parts, which carry more than 50 Amp., must be fire protection-
moderately 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 imme-
diate 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.

Mode of Operation of the Generator
Panda PMS AGT-DC 4000 - Chapter A: Mode of Operation of the Generator Page 5
A. Mode of Operation of the Generator
A.1 Mode of Operation of Operating Surveillance
Internal monitoring switches
The generator is equipped about failure switches, which are indicated on the remote control
panel, and also about failure switch, which switch-off the generator automatically without indica-
ting a failure in the remote control panel:
The remote control panel supervised the following values. In the case of a disturbance the gene-
rator is switched off, in order to avoid damage to the aggregate:
1. Cooling water temperature at engine and exhaust connection
2. Thermo-switches on the Diode block
3. Coil temperature
4. Oil pressure
The fault is transmitted, if one of these switches measures a value that exceeds the required
value (all switches are openers). The current is switched off by the main relay. (Fuel magnet
valve closes, the fuel suction pump is switched off, VCS is switched off).
The combustion engine possesses an oil pressure control switch, which switches the engine off if
the oil pressure drops under a certain value.
The additional failure switch in the generator coil, it is not indicated at the remote control panel,
interrupts directly the current supply to the main power relay. By this constellation it is guaranteed
that the generator switches off in each case when an error is present.
This measure is, if possibly, a circuit at the remote control panel failed.
Thermo-switch at engine
The thermo-switch at the engine serves
for monitoring the engine temperature.
Fig. A.1: Thermo-switch at engine

Mode of Operation of the Generator
Page 6 Panda PMS AGT-DC 4000 - Chapter A: Mode of Operation of the Generator
Thermo-switch exhaust connection
If the impeller pump should fail, the raw
water stream fed here tears off and the
exhaust connection heats up immediately
extremely fast, since the water cooling is
missing. The thermo-switch supervises a
functioning raw water cycle.

Oil pressure switch at diesel engine
The combustion engine is equipped with
an oil pressure control switch, which swit-
ches the engine off if the oil pressure
drops under a certain value.

A.1.1 Regulation of the generator voltage by the VCS
The output voltage of the generator is permanently measured by the VCS (approx. 20 times per
second!). As soon as by a consumer the voltage is affected, the speed regulation provides to
adapt to the changed power demand by appropriate change of the engine speed.
Not only by the excitation of the generator it is worked against to the initiating voltage drop, but
also by the raising of the number of revolutions whereby the drive potential improves.

Mode of Operation of the Generator
Page 8 Panda PMS AGT-DC 4000 - Chapter A: Mode of Operation of the Generator
A.1.2 Overloading of engine during longer operation
Please ensure that the genset is not overloaded. Overloading occurs when the electrical load
(demand) induces a load torque in the generator which is higher than that which the diesel drive
motor can provide. Overloading causes the engine to run rough, burn oil, creates excessive
exhaust (environmentally unfriendly) and even to stall. Extra caution should be practised with
multi-power units (single and 3-phase current generation) to avoid overloading the diesel drive
engine.
The generator should only be loaded at the peak
rated power for short periods only! A high peak
current is required to start many electrical
devices, especially electric motors and compres-
sors (from a still stand state)
The height of the rated output (P) can taken from
the identification plate attached on the housing.
In order to guarantee a long life span, the conti-
nuous load should not exceed 80% of the nominal
load. By continuous output we understand the
continuous operation of the generator over many
hours. It is harmless for the engine to supply for
2-3 hours the full rated output.
The total conception of the Panda generator guarantees that the continuous load operation does
not release superelevated temperatures of the engine also with extreme conditions. It is to be
considered that the exhaust gas values in the full load operation become more unfavorable (soot
formation).
A.2 Operation of the generator with HTG generator
A.2.1 Allgemeine Hinweise
Beside the alternating current aggregates ICEMASTER supplies also the super-compact High
tech battery load aggregates from the series of PANDA AGT in sound-insulated construction,
which represent a very interesting alternative solution in a DC-AC power technology merged for
generation of current within the mobile range.
The new HTG generators with 280 A charging current offer themselves a alternative for an
onboard current generator, if a diesel set is not intended. These generators differ according to the
technology very substantially from all conventional products. The size is so compact that you can
exchange it also against a generator according to standard. This generator can ensure a 230V
alternating current supply up to 3.000W power in connection with a PANDA HD inverter also in
continuous operation.
A.3 Operation of the generator with automatic start
If the generator set were set up far away from the location of the remote control panel that the
user cannot hear surely, whether the generator starts, a automatic starting option (accessories)
should be installed. With this option the starter is disengaged automatically, if the starting speed
is exceeded.

Mode of Operation of the Generator
Panda PMS AGT-DC 4000 - Chapter A: Mode of Operation of the Generator Page 9
A.4 Betrieb des Generators bei Einbau unter der Wasserlinie
If the generator cannot be installed clearly at least 600mm over the waterline, a vent valve must
be installed into the raw water line. At installation beside the "midship´s line" a possible heeling
must be considered!
The water hose in the sound cover is split on the heat exchanger outlet and extended in each
case in the sound cover at both ends with a connecting nipple by a hose end. Both hose ends
must led out from the sound cover to a point, which is at least for 600mm over the waterline (if
possible in the midship´s line). The valve is inserted at the highest place, at least 600mm over the
waterline.
The tube bend must be removed. Now the
two ends are extended in each case with a
hose and attached at a value of approx.
600mm over the waterline with a ventila-
tion valve.

11) Cooling water tank

Mode of Operation of the Generator
Page 10 Panda PMS AGT-DC 4000 - Chapter A: Mode of Operation of the Generator
A.4.1 Control of the vent valve
If the valve is blocked, the cooling water pipe cannot be ventilated after the stop of the generator,
the water column is not interrupted and the water can penetrate into the combustion chamber of
the engine.
This lead to destruction of the engine!
A.5 Operation of the generator with installation over the water-
line
Generator over the waterline:
If the generator is installed over the waterline, a stronger impeller wear is possible, the pump can
run after the start some seconds dry.
It is very important that the impeller is exchanged every few months. When starting the generator
attention should be always paid and heard to it, when raw water withdraws from the exhaust
neck. If this takes longer than 5 seconds the impeller must exchanged, he sucks in air before raw
water reaches the impeller (see picture below) and the impeller then wears strongly. In this case
the impeller loses his effect and raw water can penetrate into the engine as well as substantially
destroy it. If the impeller is not exchanged early enough, the entire pump must be replaced.
Otherwise the impeller wings breaks in pieces and it stresses some time to remove these again.
Replacement impeller should always be on board.
With the installation of the generator it must be paid attention that the impeller pump is well
accessible, since the impeller is a wearing part. If this place at the location can be reached not
well, an external pump with electric drive can be used instead of the pump built firmly in the sound
cover, which should be installed in a well accessible place.

B. Maintenance Instructions
B.1 General maintenance instructions
B.1.1 Checks before starting
• Oil level
• Cooling system leaks
• Visual check for any changes, leaks oil drain system, v-belt, cable connections, hose clips, air
filter, fuel lines
Once a month
• Lubrication of actuator-trapezoid thread spindle
Maintenance see TableF.4, “Inspection checklist for services,” on PageIX.
B.1.2 Hose elements and rubber formed component in the sound cover
Check all hoses and hose connections for good condition. The rubber hoses are very sensitive to
enviromental influences. They can season fast with dry air, in which environment of muted oil and
fuel steams and increased temperature. The hoses must be checked regularly for elasticity.
There are operating situations, at which the hoses must be renewed once in the year.
Additionally to usual tasks of maintenance (oil level check, oil filter control etc.) further mainte-
nance activities are to be accomplished for marine aggregates.
B.2 Oil circuit maintenance
The first oil change is to be accomplished after a period of operation from 35 to 50 hours. After-
wards the oil is to be changed after 100 hours. For this the oil SAE30 for temperatures over 20°C
and SAE20 for temperatures between 5°C and 20°C is to be used. At temperatures under 5°C oil
of the viscosity SAE10W or 10W-30 is prescribed.
Type and amount of required oil see:TableF.5, “Engine oil,” on PageX and TableF.2, “Technical
Data Engine,” on PageVII.

Maintenance Instructions
Page 12 Panda PMS AGT-DC 4000 - Chapter B: Maintenance Instructions
B.3 Execution of an oil change
Oil drain hose
For the oil change an oil drain hose is lead
through the sound cover.
Oil drain screw
The oil can be discharged by opening the
oil drain screw. For countering use a
second wrench.
Oil drain pump
If discharging of the oil is not possible, we
recommend the employment of a hand
pump, which can be attached to the oil
drain hose.
Afterwards the oil drain screw is closed
again.

Maintenance Instructions
Panda PMS AGT-DC 4000 - Chapter B: Maintenance Instructions Page 13
Oil strainer
The oil strainer must be cleaned every 500
opeatiing hours.
Open the oil filler neck
After opening the cap of the oil filler neck
the new oil is refilled.
Please wait instant, before measure the oil
level, the oil must set off in the sump.
Oil dipstick
With the help of the engine oil dipstick the
oil level is to examined. The prescribed fil-
ling level may not exceed the „Max“ mar-
king.
We recommend 2/3 oil level.

Maintenance Instructions
Page 14 Panda PMS AGT-DC 4000 - Chapter B: Maintenance Instructions
B.4 Checking the water separator in the fuel supply
The pre-filter with water separator has a
cock at its lower surface, with this cock the
downward sunk water can be discharged.
This is simply possible, water is heavier
due to its density than the Diesel.
B.4.1 De-aerating the fuel system
Normally, the fuel system is designed to bleed out air itself i.e. as soon as the electric starter
motor starts operation the fuel pump starts working and the fuel system will be de-aerated after
some time automatically. It is nevertheless essential to bleed the system as follows prior to the
first operation (as all hoses are empty):
1.Put a container under the fuel return
pipe to catch running out fuel to catch.
