IV. Sensor element
1. Loosen screw (D1) and push sensor bracket (D)
downwards, see Fig. [3].
2. Disconnect plug-in connector between sensor cable (E1)
and electronic module (A), see Fig. [15].
3. Disengage sensor (E) at the bottom and detach from
bracket (D), see Fig. [4].
Assemble in reverse order.
Disconnect and reconnect plug-in connector between
electronic module (A) and transformer (H), see Fig. [11].
After reconnecting power supply, position detection begins.
V. Sensor for wall installation
1. Disconnect plug-in connector between sensor cable (E1)
and electronic module (A), see Fig. [16].
2. Close isolating valve (B), see Fig. [8].
3. Remove urinal.
4. Turn retaining tabs (K) and remove sensor (E), see Fig. [6].
Assemble in reverse order.
Disconnect and reconnect plug-in connector between
electronic module (A) and transformer (H), see Fig. [11].
After reconnecting power supply, position detection begins.
Replacement parts, see fold-out page I

Fault/ cause/ remedy
Fault Cause Remedy
No flushing • Water supply interrupted - Open isolating valve
• Filter in solenoid valve blocked - Clean or replace filter, see Solenoid
valve and filter maintenance
• Plug-in connector without contact - Attach plug-in connector
• The detection zone of the sensor system
is set too low/too high
- Increase/reduce range, see Settings,
Setting the range
• Solenoid valve defective - Replace solenoid valve, see Solenoid
valve and filter maintenance
• Transformer faulty - Replace transformer, see Transformer
maintenance
• Software lock activated because
compensation routine has been
performed 25- times
- Reset counter, see Resetting counter
• Electronics defective (indicator lamp
not flashing or permanently on)
- Replace electronic module, see
Maintenance of electronic module
Water flowing continuously • Solenoid valve defective - Replace solenoid valve, see Solenoid
valve and filter maintenance
Undesired flushing • The detection zone of the sensor system
is set too high
- An opposite object will be detected.
Reduce range, see Settings,
Setting the range
Flow volume too low • Flow volume set too low - Adjust flow volume, see Settings,
Setting the flow volume
• Filter in solenoid valve defective - Clean or replace filter, see Solenoid
valve and filter maintenance
• Filter in solenoid valve blocked - Clean or replace filter, see Solenoid
valve and filter maintenance
• Solenoid valve defective - Replace solenoid valve, see Solenoid
valve and filter maintenance
Flow volume too high • Flow volume set too high - Adjust flow volume, see Settings, Setting
the flow volume
• Solenoid valve defective - Replace solenoid valve, see Solenoid
valve and filter maintenance
Position detection is not
performed (No flushing)
• Replacement part exchanged,
no position detection
- Reset counter, see Resetting counter
• Software lock activated because
compensation routine has been
performed 25- times
- Reset counter, see Resetting counter
