Signal
“Robot-Stop” (Robot stop via button)
In [A40] robot operation must be configured and assigned to an output relay
[default = A2 = 2].
Also pay attention to the setting in [A41], so that in the event of a power failure the
robot is correctly controlled. See section 4.6
In OFF mode
Press “ROBOT STOP” button: The robot is started or stopped again (toggle func-
tion). The LED indicates the present status.
If the robot is active (LED “Robot Stop” off) washing will not start. If the washing
button is pressed, the LED will flash.
If cooling mode is activated while the robot is switched off, the robot will start au-
tomatically.
In cooling mode
switching to OFF mode, the robot remains active.
If the button “Robot Stop” is pressed for 3 seconds, the robot is stopped and cool-
ing mode ends.
In cleaning mode
The button “Robot Stop” does not have a function.
If a fault occurs during washing: the robot is stopped.
When washing is successfully completed:
the robot is automatically released, and
the control unit switches to OFF mode
(cooling must then be started manually or by the robot)
or
if “Automatic start to cooling” is set: cooling mode is activated automatically.

unit has not yet switched back to OFF mode.

When washing is successfully completed the robot can start cooling via a digital in-
put. (Digital input [A22..A33] => must be set to 2).

pressed before the ro-
bot is stopped, the RO-

idly.
