Operating Manual for
FAN Press Screw Separator PSS 1.1-300
S
5.1 SETUP AND OPERATION OF THE MOTOR
The motors in the standard design are suitable for operation up to a maximum ambient temperature of
+40 °C (104 °F) as well as an elevation of up to 1000 m above sea level.
Conditions of high humidity (e.g. locations near to the coast) and extreme sunlight require special de-
signs for the gears and motors. Consult the manufacturer concerning such designs.
The motors must be set up to allow unimpeded inflow of fresh air and dispersal of warm air. Removal of
the fan blade and the fan housing or enclosing the motor in a housing are prohibited since the supply of
cooling air would be reduced in both cases. This would cause the motor to overheat.
DANGER
Before making changes or inspecting the motor or switch cabinet, the machine
must be disconnected on all sides and all poles and secured against reactivation!
Always keep the switch cabinet closed!
DANGER
It must be noted that a pressed EMERGENCY OFF button does not provide any pro-
tection against unauthorized starting of the machine.
5.2 CONDENSATE HOLE
We recommend a condensate hole on motors that are subjected to high temperature fluctuations or
extreme climatic conditions.
DANGER
A motor protection circuit breaker or a protection device with overload relay must always
be installed to protect the motor winding. Fuses do not protect the motor from overloads;
they only protect the electrical supply lines or switching systems from damage in event of
a short-circuit.
5.3 INSTALLATION WITHOUT SWITCH CABINET
If the FAN press screw separator was delivered or ordered without a switch cabinet, a few basic
rules must be followed in controlling the separator; otherwise, the warranty is void:
The motor must be equipped with electrical protection to prevent impermissible current loads ex-
ceeding the rated current on the type plate.
Operating the press screw separator without an inflow of material must be prevented by means
of electrical control since dry running would otherwise result in increased wear on the screen and
auger, which would significantly reduce their service lives. For this reason, the separator should
be started up along with the start of the medium supply and stopped between 30 and 60 seconds
after the medium supply is stopped.
