Retrieving a fault code message by signal lamp
The fault message that caused the system to malfunction can be retrieved by pushing the duty
mode push-button for at least 6 seconds (20-sec. max). Directly after releasing the push button the
signal lamp will show the fault message by flash code (does not function with switch-button on
display).
The signal lamp indicates the fault codes by flashing:
-
Dozens are shown by long pulses (0,5 seconds)
-
Units are shown by short pulses (0,15 seconds)
Examples
Code that causes a pump to shut-off
Code that do not cause a pump to shut-off
ATTENTION
Fault codes can only be retrieved when the pump communication line (pin/wire no. 6) is not
connected to an Uni- or PC-GINA and need to be disconnected for at least 50 seconds before a code
can be retrieved.
