Genmac provides one-source responsibility for the

generating system and accessories.

All units and components are prototype tested, factory
build and production tested. A specific control
procedure during the several stages of production
ensures long life and reliability.

Rugged 4 cycle heavy-duty Industrial diesel engine, of
primary brands with direct fuel injection system and swirl
intake ports combine for a low fuel consumption and
excellent transient response.

Powerful alternators with insulation system of H class and
impregnation made with tropicalized epoxy resins, are
used as standard.

Generator set accepts one-step 100% of full load.

The variation of the Voltage is maintained between +-
1,5% by sophisticated Electronic Voltage Regulators.

Fully programmable AMF controller is supplied with auto
ST AR start control system and digital instrumentation.
Automatic device for setting the periodic exercise is
integrated into the AMF.

Heavy-duty built-in anti-vibration insulators assures lower
noise and longer components life.

Protection guards on rotating parts

Fork-lifting facilities are supplied together with 4 lifting
brackets on the base frame

The Silent version consist of a weather-proof bolted
modular pre-painted enclosure (2000/14/CE compliant)
with hinged lockable doors, radiator coolant hatch,
base mounted radiator coolant and engine oil drain
lines. These items affords superior flexibility and ease of
maintenance.

A stub-up area is provided to make easier the electrical
connection to the load.

A wide range of accessories is provided on request in
MASTER
order to satisfy the needs of the user and to let the
generator work in almost every condition.

RATING DEFINITION
Standby Rating: Applicable for supplying emergency power for the duration of normal power interruption limited to maximum 500h per year within
the following maximum operating time: 100% load 25h per year, 90% load 200h per year.
No overload capability is permitted for this rating. “Limited Time running Power (LTP)” rating conforms to ISO 8528-1.
Prime Rating: Applicable for supplying power at a variable load for an unlimited number of hours per year. A 10% overload capability is available for
one hour in twelve hours periods. This rating conforms to ISO 8528-1 “Prime Running Power (PRP)”.
STANDARD REFERENCE CONDITIONS:
The above mentioned power data are calculated with: air temeparture of 25°C (77°F); 99kPa of barometric pressure, 100m of altitude a.s.l and 30%
of relative humidity. For different conditions please refear to the derating factor’s table specific for this engine.

CONTROL PANEL

CIRCUIT BREAKER
50Hz – 400V generators are supplied together with a circuit
breaker that permits a thermal protection against overloads
and magnetic protection against short-circuit.
For 60Hz or 50Hz-230V versions the circuit breaker has to be
ordered separately indicating the voltage at which the
generator has to work. All the generator of this line are fully
re-connectable according to the specification indicated in
the “RATINGS BOOK”

AUXILIARY SOCKETS
A special box with sockets or quick connectors or
connection boards can be supplied as an option in order to
ease the fast connection between the generator and the
electrical line or between the generator and the loads.
Please refer to the apposite section on the “ACCESSORIES
PRICE LIST”.

COMMANDER C-08
C-08 is a high performance, latest generation controller that includes a sophisticated digital multi-meter, an engine protection
card and a controller with “Autostart” logic, “Automatic Mains Failure logic” and “Dual logic”.
Its big display (320x240 pixel; visible area 115x85mm) permits to see all the main measures at the same time. With C08 controller a
piece of equipment is no longer considered as a single entity, but controlled and operated keeping in mind the entire application
system it belongs to and its environment.
Its easy-to-use keyboard has the possibility of blocking all or some of the keys to avoid tampering in the system. Here follows a list
