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 gensets developed at that time set new technological standards worldwide.
The gensets became more efficient and powerful than other gensets 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 stabi-
lity 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 genset 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 gensets 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
genset 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)

CALIFORNIA
Proposition 65 Warning
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 Precautions
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.
Protective Conductor:
The generator is „earthed " as standard (The centre and earth are connected by means of a bridge in the generator
terminal box). This is a basic safety function, which offers basic safety as long as no other component has been
installed. It is, above all, conceived for supply and an eventual test run.
This "earth" (PEN) is only effective, if all parts of the electrical system is earthed, and has a common “potential”. The
bridges can be removed, if this is required for technical reasons and another protection system has been installed.
The full voltage is exploited at the AC control box, when the generator is run. It must therefore be ensured
that the control box is closed and cannot be tampered with, if the generator is running.
The battery must always be disconnected, if work on the generator or electrical system is to be carried out,
so that the generator cannot be unintentionally started.
It is not allowed to disconnect the battery during operation!
After the generator has stopped the battery can be disconnected!
Switch off all load when working on the generator
All load must be disconnected, in order to avoid damages to the devices. In addition the semi conductors in the AC
control box must be disconnected in order to avoid the boat capacitors being activated. The minus pole of the battery
ought to be removed.
Capacitors are required to run the generator. These have two varying functions:
A) The working capacitors
B) The (Booster) capacitors
Both Groups are located in the sound cover of the genset.
Capacitors are electrical stores. There could be a residual of high electrical current at the contacts for a period dis-
connection from the circuit. The contacts my not be touched for safety reasons, If the capacitors are to be exchanged
or checked, then a short circuit between the contacts should be made so that the stored energy is discharged.
If the generator is switched off in the normal manner, the working capacitors are automatically discharged by means
of the windings. The booster capacitors are discharged by means of internal discharge resistors.
All capacitors must be short-circuited before work is carried out on the AC-Control box for safety reasons.

5 Safety steps to follow if someone is the
victim of electrical shock
Do not try to pull or grab the individual.
Send for help as soon as possible.
If possible, turn off the electrical power.
If you cannot turn off the electrical power, pull, push, or lift the person to safety using a
wooden pole, rope, or some nonconductive material.
After the injured person is free of contact with the source of electrical shock, move them a
short distance away and immediately start necessary first aid procedures.

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 genset:
1. Cooling water temperature at cylinder head, at exhaust manifold and exhaust connection
2. Raw water and fresh water temperature
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 also 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 cylinder head
The thermo-switch at the cylinder head
serves the monitoring of the generator
temperature. All thermo-switches for the
generators from Panda 6.000 upward are
two-pole and laidout as "openers".

Oil pressure switch
In order to be able to monitore the lubrica-
ting oil system, an oil pressure switch is
built into the system. The oil pressure
switch is on the back of the engine (below
the oil filter).
Fig. A.11: Oil pressure switch
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 load 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.
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.

Mode of Operation of the Generator
Page 10 Panda_12mini_PMS_Digital_s00865_Installation manual.V02 - Chapter A: Mode of Operation of the Generator 23.1.07
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.1.3 Use the failure bypass switch for fuel delivery
Switch on the "Stand by"-switch at the
control panel. Functional elements must
shine.
Press „Failure bypass switch“ (located at
the air suction housing) and hold. The
electrical fuel pump must run audibly. The
pressing of the switch become audible
switching on and off of the fuel solenoid
valve at the generator (with removed
sound cover).
Fig. A.12: Failure bypass switch
A.2 Operation of electric motors with high starting current
A.2.1 General references
Electric motors can need for a very short time an increased starting current when starting. The
starting current can amount to up to 10 times of the rated current. This applies in particular to 2-
pole engines and particularly to fan engines with larger power, in addition, to engines, which com-
pressor with flywheels or the like propels. If such engines are to be operated, contact the techni-
cian of Fischer Panda, in order to find suitable measures, which work against the high starting
current and/or layout the generator for the higher starting current.
A.2.2 Compensation of 1 phases engines
If inductive electrical load is connected, then there is a phase shift between current and voltage;
the portion of the blind current becomes larger. This effect meets by automatic activating of addi-
tional capacitors and compensates the idle current. This compensation of the inductive load cau-
ses that the efficiency of the generator is increased. By the automatic compensation can more
engines or a larger electrical load with an inductive character be operated. In other words: the
usable power of the generator is increased.
A.2.3 Compensation of 3 phases engines
See folding sheet "Operation Instructions for Generator with Inductive Loads"
