10 Troubleshooting

Problem

Possible cause

Troubleshooting

No LED display

No voltage supply

Apply voltage

The device does not
switch, not even after
undamping and re-
damping

The device was brought into the safe
state (logic "0"). Cause:
• Cross fault between both outputs A1

and A2

• Cross fault between one output (A1

or A2) and the supply voltage

• Error in the device detected

• Remove the cross

fault

• Replace device

11 Maintenance, repair and disposal

If used correctly, no maintenance and repair measures are necessary.

Only the manufacturer is allowed to repair the unit.

u

After use dispose of the device in an environmentally friendly way in
accordance with the applicable national regulations.
