Installation
10.3 Sediment level measurement
While the service program is activated,
the safety check for the collector vessel
is deactivated�
The sediment level measurement can be used
to check the function of the sediment sensor
and the function of the LEDs�
Every time the service key is pressed, the sedi-
ment level is checked� If a test collector vessel is
used for this, the different levels can be scanned
and made visible on the display panel�
While changing the collectors (collector vessel -
test collector vessel ) in the service program the
unit remains in the ON state�
10.4 Motor start - motor braking
The drive motor starts and, after approx� 5 sec-
onds, braking is applied� If the service key is
pressed during these 5 seconds, the motor will
immediately be braked�
This procedure can be repeated by pressing the
service key 1x again�
The drive motor starts up�
As a result of the rpm monitoring, the LED will
change from orange to green upon start-up and
from green to orange upon braking�
10.5 Input and output signals
– After this program item is activated, the yellow
LED flashes and a cycled DC voltage (approx�
22-30 V) can be measured at the terminal for
the rinsing unit�
– If the suction hose is lifted off the hose mani-
fold the green LED will also come on�
– Removal of the collecting container causes
the red LED to illuminate�
