Before opening the control unit
pull the mains plug!
Then wait 10 min. until the power pack is discharged.
Connection is done on the XK1 terminal strip.
In control mode with 0-10 volts

In control mode with 0-20mA
onto terminal XK1.4 +20mA
Terminal XK1.5 GND
3.2.1 Reversing mode
Before connecting, the right-hand side panel of the unit has to be opened.
Before opening the control unit
pull the mains plug!
Then wait 10 min. until the power pack is discharged.
To activate the reversing mode, connect a voltage-free contact onto terminals XK1.9 and XK1.8. When switching the
sense of rotation, the motor stops a moment and then starts in the opposite moving direction at the set speed. If the sense
of rotation is reversed without switching or if the contact is open, the motor will run in the set sense of rotation.

Release of the function through external components
The standard adjustment of the control unit makes sure that the oscillating belt drive starts when the mains switch is
switched on. If the control unit is to operate without disconnection from the mains in the Start-Stop mode, the control unit
is to be opened by observing the above-mentioned safety notes. The blind plug at the side of the case replaces a screw
fitting with strain relief size M16. This is where the cable for the release is lead through. There are two possible ways of
performing a release:
Release through a contact
The way this simple and economical solution works is that a contact releases the control unit by closing and the belt drive
runs. The connection is made on terminals 7 and 9; the jumper put in at the works is to be removed. At the same time,
please remember the following:
There is voltage in the connection! Cable type and colour as well as insulation regulations must be observed; the
contact must, of course, be voltage-free.
The cable may not be installed in the immediate vicinity of high-energy switching equipment or strong interference
fields.
Release through a voltage signal
The signal is connected to terminals 6 - and 7 +; the jumper, i.e. terminals 7 and 8, have to be removed. The drive starts
when there is a signal between 10 and 30 volts DC in correct polarity. The input is protected against wrong polarity. The
use of an optocoupler in the control unit makes the input voltage-free and allows one to install unshielded cables of almost
any length. However, high-energy interferences must be avoided here too.
