10 Malfunctions
10.1 Diagnostics
LED display
Operating statuses and errors are indicated by flashing light-emitting diodes.

Tab. 7: LED display
Display of error codes
The error code is displayed by 4 short flash pulses of the Power LED (green). Then the Error LED (red)
displays the error code (number of flash pulses = error code). The flash pulses for both LEDs repeat
continuously. The LEDs only stop flashing when the operating voltage is switched off in order to clear
the error.
Overview of error codes:
Fig. 18:
Example of error code
After 4 short flash pulses of the Power LED 1, there are 6 long flash pulses of the Error LED 2.
This indicates error code 6 (pneumatic fault). A pneumatic fault occurs, for example, if the operating
pressure is below the required minimum pressure or there is no pressure at all.
10.2 Fault clearance
– Check compressed air supply
–
Check power supply
– Check installation of the signal lines
