Note!
This hand indicates that there are tips on how to use the control unit.
Attention!
This warning triangle indicates safety instructions. Non-observance of this warning can result in serious
injuries or death!
Work on electrical equipment of the machine/installation may only be carried out by a qualified electrician or
by an instructed person under the directions and supervision of a qualified electrician according to the
electrotechnical regulations!
Please observe all notes on safety and danger on the machine/installation!
The electrical equipment of a machine/installation is to be inspected and checked regularly. Defects like
loose connections or damaged cables must be eliminated immediately!
Before putting the machine into operation, one must make sure that the protective conductor (PE) is
installed at the connecting point and that it is intact. Only approved testing equipment may be used to check
the protective conductor.

Starting Instructions
Before connecting to the mains and switching on the control unit, the following points must be checked:
Is the control unit properly closed with all its screws?
Are the existing plug-in fixing devices locked into place / screwed tight?
Are all cables and bushings intact?
Is the INTENDED USE guaranteed?
Does the indicated supply voltage on the control unit conform with the local power supply network?
The control unit may only be put into operation if all above questions can clearly be answered with Yes.
3.1
Basic factory setting
The control units are set at the works as follows:
Minimum output voltage:
4.9 volts;
Maximum output voltage:
25.5 volts;
Maximum load current:
1.5 amp.
In special cases or after modifications, a readjustment may become necessary, for which the following must be observed:
The maximum output voltage and the maximum load current for the conveyor belt FP 15 may not be adjusted higher nor
may the minimum output voltage be adjusted lower than indicated above.
It is also important to note that the potentiometers for the output voltage are not reactionless towards each other. This
means that a change in the maximum voltage also slightly changes the minimum voltage
– and vice versa. Therefore, it is
possible that both potentiometers may have to be adjusted several times.
3.2
External adjustment with 0-10V or 0-20mA
Before connecting, the right-hand side panel of the unit has to be opened.
