NOTICE
The EasyClean can be operated without the inductive check-back position indicator or
flow sensor. In this case the following terminals must be bridged, so that no fault
messages are generated:
– terminal nos. 1 and 2 connected
– terminal nos. 4 and 5 connected
– terminal nos. 25 and 26 connected
NOTICE
For remote indication of EasyClean alarms (e.g. warning light, horn or other external signaling
equipment) the alarms can be powered by the EasyClean itself (24 V / 5 W). Bridge terminals
no. 12 and 13. Connect alarms to terminals no. 11 and 14.
