c
– 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.
6.4.9 Manual control
Function The Manual control function can be used to test the operativeness of
an instrument that is connected to the relay. To do so, close or open the
relay manually and, while doing so, check the behavior of the
connected instrument.
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.
