10. Checking the sensor

☞
In the first 4 minutes after the sensor is started up, the LED indicates the response of
the sensor (flashing or steady).
☞
If the sensor needs to be checked again, the power pack and control unit must be
disconnected for at least 20 seconds.
10.1 Connect the control unit to the power pack.
• The LED gives 6 quick flashes and 1 long one.
10.2 Move your hand directly in front of the sensor.
• The LED on the control unit lights up.
10.3 Withdraw your hand from the sensor after 5 seconds.
• The LED is off.
• Roughly 8 seconds after the end of the detected motion, the solenoid valve is
opened for the duration of the set flush time.

11. Function

11.1 Use the urinal.
• The water flows after a delay time of 10 seconds.
• The water flow stops automatically once the preset flush time has expired.
☞
As of a total flush time of 6 seconds, a flush pause of 2 seconds and a remaining
flush time of 3 seconds take place to ensure that the odour seal works.
☞
The flush time is adjustable between 4 and 15 seconds (see
☞
24 h after the last use, an automatic flush takes place with the set flush quantity.

Overflow protection

A full or partial blockage prevents automatic flushing until the blockage is rectified.
Once the blockage has been rectified, the system can be used without restriction
immediately.
Cleaning
If commercially available cleaning foam is used, no immediate flushing is triggered.
If other cleaning agents are used, a delayed flush normally takes place.
Stadium mode
If 5 uses take place with a gap of < 30 seconds in each case, the sensor switches to
stadium mode. In this mode, flushes are carried out at a greater time interval of
60 seconds. When the end of constant usage is detected (no use within
60 seconds), the sensor automatically switches back to normal mode.
