– By switching on the maintenance condition
Each time the cleaning cycle is canceled, the relay opens immediately.
If the cleaning cycle is canceled automatically, the outputs linked to the
sensor are released immediately.
If the cleaning cycle is canceled manually, the sensor is in the
maintenance condition. The linked outputs are only released after the
maintenance condition was terminated manually.
The next cleaning cycle will be performed at the time set up.
Note
In case of a power failure, all relays open. The cleaning cycle is
canceled. The outputs linked with the sensor change to the non-active
condition (see section 6.5.2). As soon as the power is available, the
outputs are released again. The next cleaning cycle will be performed
at the time set up.
