9.15.1 Cleaning release by robot
r27 Cleaning release via digital input
0:
deactivated
1:
activated
Explanation
Setting the parameter [r27] to 'active' is only useful for robot operation.
If the cleaning button is pressed after the tank has been emptied by the truck driver,
it may be that the robot is not ready for the cleaning process, depending on the
configuration of the connected robot.
The WTS-300 can be configured in such a way that washing is not started directly
by pushing the button, but in addition a robot release signal is needed.
Procedure
If the cleaning release in parameter [r27] is set to 'active' and the CLEANING button
is pressed,
- the display shows 'CLEn'
-
the “washing“ mode LED flashes
As soon as the robot is released, the cleaning process is started - the mode LED
remains lit permanently and the programme step for the cleaning process appears
in the display
Note: The function can be deactivated by pressing the OFF key during the waiting
period until the cleaning release 'CLEn' is activated.
Parameter setting - IMPORTANT
In order for the cleaning release to take place, the robot release signal must be as-
signed to one of the digital inputs. It is preferable to use terminal 45, since this is
already configured at the factory via parameter [A27].
