4.5.7 Cleaning
Note
When using the MIQ/CHV PLUS valve module, it is best to set the
Cleaning function directly at the valve output (V) of the MIQ/CHV PLUS
(see operating manual of the MIQ/CHV PLUS). The relay can then be
used for other purposes.
Function The Cleaning function enables the time controlled automatic start of the
sensor cleaning function with the aid of a relay of the combi output
module.
The relay controls the MIQ/CHV valve module and switches on or off
the compressed air for the CH sensor cleaning head.
In order to set up the Cleaning function for a relay output, the relay
output must be linked with a sensor (see section 4.3).
The relay assigned to the combi output module always works as a
closer.
The cleaning cycle consists of Cleaning duration and Adjustment time.
During the cleaning cycle the Clean display flashes. The outputs linked
with this sensor are frozen. The maintenance condition (see
section 4.9) 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 relay with the Manual control function (see
section 4.5.9) 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 will start in a few minutes
(settings: see following table).
