5.5 Stabilisation of the output voltage for fluctuations in the line voltage
By means of the integrated voltage stabilisation function, the output voltage and hence the speed of the connected
motor remain essentially constant throughout fluctuations in the line voltage.
The unit supplies the maximum output voltage (approximately the line voltage) for line voltages above the signal input
which are less than the specified output voltage. The output voltage of the unit cannot rise above the line voltage for
system reasons.
Characteristic for ohmic loads

Stabilisation of the output voltage can be switched on and off again with the jumper J3.
Jumper J3 “up”:
without stabilisation (
factory setting
)
Jumper J3 “down”:
with stabilisation
The stabilisation must be switched off when loading the voltage supply for external
units (+15 V / +24 V) (section 5.3 Voltage supply) or for running from a mains
transformer.
It is not meaningful to operate with stabilisation for control (0-10 V) by a control unit
(e.g. when used as a “follower controller”).
The function “stabilisation” serves to specify a voltage as constant as possible, e.g.
over a potentiometer.
5.6 Output voltage 0-10 V
The output voltage 0-10 V, (terminal “A” / “GND”) is almost proportional to the regulated motor voltage. This can be used
for example, if a speed controller, type PAE / PASTE, or valve positioning motor, is installed. The output is set to a fixed
voltage of 10 V at the factory for supply to a potentiometer. A switchover to 0-10 V proportional to the motor voltage is
possible by means of the connector J10 in the terminal compartment.
J10 „up“ position „A“ (
standard setting
) = fixed voltage to terminal „A“ (+10 V for potentiometer)
J10 „down“ position „B“
= voltage to terminal „A“ 0-10 V proportional to the controlled motor

6. Faults and their rectification
6.1 Line faults
The controller switches off in the event of a line fault, e.g. fuse or network failures. The controller switches on again
automatically following restoration of the voltage.
