Tectron Skate for flushing cistern GD 2 38 698<br />
Problem Cause Remedy<br />
Indicator lamp on • Obstacle during calibration<br />
front of electronics<br />
flashing continuously<br />
after<br />
calibration<br />
• Servo motor defective<br />
• Perform calibration again ensuring there is<br />
no obstacle in the adjustment range of the<br />
sensor motor, see Maintenance, Calibrating<br />
the servo motor<br />
• Replace servo motor, see Maintenance,<br />
Replacing the servo motor<br />
No flushing<br />
• Water supply interrupted<br />
• No voltage (indicator lamp on rear of electronics<br />
not flashing)<br />
• Electronics defective (indicator lamp not flashing or<br />
permanently on)<br />
• Servo motor defective (rotation will not be executed)<br />
• Plug-in connectors without contact<br />
• The detection zone of the sensor system is set too<br />
low/too high<br />
• Servo motor defective<br />
• Switch on power supply or check plug-in<br />
connection or transformer defective, see<br />
Maintenance, Replacing the transformer<br />
• Replace, see Wall plate with electronics<br />
maintenance<br />
• Replace servo motor, see Maintenance,<br />
Replacing the servo motor<br />
• Attach plug-in connector<br />
• Increase/reduce detection zone using<br />
remote control (special accessories 36 206)<br />
Water flowing<br />
continuously<br />
Undesired<br />
flushing<br />
Flow volume too<br />
low<br />
• Waste valve not closing<br />
• The detection zone of the sensor system is set too<br />
high<br />
• Flow volume set too low<br />
• Waste valve not lifting fully out<br />
• Servo motor defective (rotation will not be<br />
executed)<br />
• Adjust servo motor position, see Maintenance,<br />
Adjusting the servo motor position, or waste valve<br />
defective (replace, repair), see Cistern instructions<br />
• An opposing object is detected. Reduce detection<br />
zone using remote control (special accessories<br />
36 206).<br />
• Adjust flow volume, see Maintenance,Setting the<br />
waste valve to 9 l flow volume<br />
• Adjust servo motor position, see Maintenance,<br />
Adjusting the servo motor position<br />
• Replace servo motor, see Maintenance,<br />

Flow volume too<br />
high<br />
• Waste valve set to 6 litres<br />
• Flow volume set too high<br />
• Set waste valve to 9 litres, see Maintenance,<br />
Setting the waste valve to 9 l flow volume<br />
• Adjust flow volume, see Setting flow<br />
volume<br />
Setting mode<br />
The flow volume can be checked and changed in setting mode (see Setting the flow volume).<br />
The detection zone of the fitting can be checked. The indicator lamp in the sensor system of the fitting illuminates in<br />
setting mode when the detection zone of the fitting is reached by an approaching user.<br />
It is possible to set the detection zone via the optional remote control. Flushing is immediately triggered when the<br />
detection zone isexited again. The minimum delay time of 7s is not available in setting mode. <strong>To</strong> activate setting<br />
mode, proceed as follows:<br />
Disconnect the power supply to the electronics and reconnect after 5s. The plug connection between the servo<br />
motor and the electronics must not be detached!<br />
Setting mode is activated.<br />
Setting mode is automatically terminated after 3 min.<br />
