Important instructions for electrical connection
If your mains connection for the PP40 includes a fault-current
protective system, fault throwing may result through the antiinterference wiring of the frequency converter when this is
switched on (switching on takes place each time the pressing
chamber hood is closed).
If the values on the type plate are not observed this can
result in damage to the electrical and mechanical
components.
Inactive interface Sc for optional data communication
with an external device. This necessitates updating of
the software.
(Fig. 3 Serial interface)
The interface cables must not be longer than 2.5 m.
Longer cables can cause disturbances during transmission of
data.
Sc
Fig. 3 Serial interface
1. Electrical connection without a protective conductor PE is not
permissible.
2. The drive of your PP40 is fitted with a frequency converter. To
fulfill the EMC directive this is fitted with a line filter and shielded
cables to the motor.
This can occur without there being a fault on your PP40 or your
mains installation.
According to state of the art selective a.c.-d.c. sensitive faultcurrent protective systems are recommended for such cases. The
tripping current must be adequately dimensioned since
capacitive compensating currents occurring only for a short time
(shielded cables, line filter) when switching on can easily cause
fault throwing.
Under certain circumstances it may be necessary to operate the
PP40 without a fault-current protective system. In this case,
however, it should be checked whether this is inconsistent with
the local regulations of the electricity supply company or other
applicable institutions or standards.
Serial interfaces
08.02.2012 Retsch GmbH 12 0002
Operation
Ensure that the voltage and frequency of your mains supply
correspond to the values on the type plate of the PP40. The

Contrast and brightness can be adapted to each user or to the environment (sunlight, dazzling etc).
If you have accidentally selected the wrong contrast or brightness (the display can no longer be seen), switch
off the unit at the main switch, keep the buttons START, STOP and LID OPEN pressed simultaneously and
switch on again. You are now in the language selection and the setting values CONTRAST and BRIGHTNESS
have the works presettings again.
The actual date and time can be entered here.
The time then appears in the stand-by monitor.
The unit can be disconnected from the mains for up to 30 days without the settings being lost.
Stand-by monitor
After 15 minutes inactivity of the unit (times after a STOP command) the stand-by monitor switches on
automatically.
By pressing one of the buttons, or touching the setting knob, the stand-by monitor disappears without carrying
out the command which has been made.
If you were in a sub-menu when the stand-by monitor was activated, you return to this selection window
automatically.
The stand-by monitor cannot be set and cannot therefore be switched off.
