Cleaning
Function
The
Cleaning
function enables the time controlled automatic start of the sensor
cleaning function with the aid of a relay of the combination output module.
The relay controls the MIQ/CHV valve module and switches the compressed air
for the CH sensor cleaning head on or off.
In order to set up the
Cleaning
function for a relay output, the relay output must
be linked with a sensor (see section 7.4).
The relay of the combination output module assigned 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 7.10) 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
complete. 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 7.6.9) 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, the reference time can be set so that
the next cleaning cycle will start in a few minutes (settings: see following table).
Settings
If the valve module MIQ/CHV PLUS is used, it is best to set the
Cleaning
function directly at the valve output (V) of the MIQ/CHV
PLUS (see operating manual MIQ/CHV PLUS). The relay can be
used for other purposes.
