13.4. Troubleshooting instructions
The DCM 21-i control unit make troubleshooting much easier for the
installer. The display not only shows you the currently activated inputs, but the
controls also have a memory, which stores the last 10 malfunctions (software)
see instruction point 13.1. and the last 50 activations (safety inputs etc.) – see
instruction point 13.2. incl. time display.
Proceed as follows to read out the currently actuated inputs:
Press the "Escape/Menu" key repeatedly until the display shows "Last com-
mands". Now press the "Escape/Menu" key again.
Now the current status of the motor is shown in the first line of the display. The
second line of the display shows you the currently activated/operated inputs.
