9 Troubleshooting
During operation the display can show a defined error code. A reason can be the buffer
overflowing, a temperature value out of range or a overshooting of the actuating system. Promptly
the error code is provided on the display and on the connected PC too. The code is 16bit wide and
it’s binary-coded (
ERROR,FWch0,FWch1,FWch2)
. The code is based on follow:
bit
description
0
actuator not connected
1
actuator with shorten circuit
12
out of range downwards
13
out range overshooting
14
wrong actuator type
15

Please check the main voltage supply and all connections. Please check the
position of the main power switch on the back side. Please check if the main
power module plugged in (indicated by a LED)
dispaly shows: „not
connected“
Please check if the actuator is plugged in and the connector fixed by the
screws correctly. Please check all cables and connectors for any damage.

loop mode
Check the value of the Offset. High modulating voltage overdrives the
amplifier. Switch off the modulation or reduce the modulation voltage until
sign is off.

loop mode
Buffer overflow: please check the status of the actuating system. The system
must be able to move over the entire travel range without limitation. Also an
mechanically overloaded system can cause this error code. For more
information about the max. load, please check the calibration information
provided with the actuating system.

The resonant mode of actuating system is reached. The calibration data needs
to be adjusted according to the load or control function. Reducing of the
applied load.
