4.4.1 Cleaning
Function The Cleaning function enables to start the sensor cleaning function
automatically and time-controlled. The valve switches on or off the
compressed air for the CH sensor cleaning head.
In order to set up the Cleaning function for a valve output, the valve
output must be linked with a sensor (see section 4.2).
The cleaning cycle consists of Cleaning duration and Adjustment time.
During the cleaning cycle the Clean display for the sensor that is being
cleaned flashes. The outputs linked with this sensor are frozen. The
maintenance condition is active.
After the Cleaning duration, the relay is opened. During the following
Adjustment time the outputs remain blocked.
The outputs linked with this sensor are only released when the cleaning
cycle is completed. The Clean display disappears. The maintenance
condition is finished.
Testing the
operativeness
You can test the operativeness of the cleaning system as follows:
manually open or close the valve with the Manual control function (see
section 4.4.3) and, while doing so, check the behavior of the cleaning
system.
Alternatively, you can test the operativeness of the cleaning system by
checking the performance of the function at the start time set up
(reference time ± interval). To perform a test immediately, you can set
the reference time so that the next cleaning cycle will start in a few
minutes (settings: see following table).
