input.
Figure 5: Fault Code Table (Sheet 2 of 2)
If a fault indication has been observed and the corrective action implemented, the inverter can be reset by applying a
STOP (low) signal to the run/stop input (terminal X11.3) followed by a RUN (high) signal to the same input.
Alternatively, the incoming mains voltage can be switched off and then switched on again.

5.5 Fault Relay

A single pole changeover relay is provided to indicate a fault. It is normally energised when the inverter is powered and
operating or stopped. If a fault condition occurs, the relay will be de–energised. The contacts of the relay are connected
to terminals X11.19 (normally open, de–energised), X11.20 (common) and X11.21 (normally closed, de–energised) on
the control board.
