9.3. possibilities of the error correction
In some rare cases it might happen that the main fuse breaks when the system is
switched on. Before opening the power supply be sure that the power cord is
removed from the system. The main fuse is placed inside the power supply
module. Use only fuses with same value for replacement. Do not hesitate to ask
your local representative for support.
Please protect the power cords from harm or shorts, which could cause
malfunction of the equipment. Large strains on the cords can cause interruptions.
In open loop configuration the output voltage can be read from the display without
plugging in the actuator.

check the position of the adjustable potentiometer and the
amplitude of the modulation signal. High modulating
voltage overdrives the amplifier. Decrease the modulation
signal or reduce the control voltage until OOR-LED is off.
table 15: possible error correction
The equipment is calibrated before delivery for the appropriate actuator
with integrated measuring system. An exchange of the actuator-amplifier-
combination leads to inaccuracies in setting movement and positioning
accuracy is lost. If the equipment is damaged during effort of another
actuator, no assurance can be undertaken!
The equipment customization makes adaptations
according customer
preferences that are possible in terms of the technical threshold values e.g. the
main voltage or the output voltage. Please contact our technical service
department in order to find out the possibilities for your specific application.
Special adaptations must be paid for by the customer.
