This system is very robust and does usually work for many years of constant operation. However if there is
a problem use this guide to troubleshoot if there is a sensor or controller malfunction.
Note that repairs is not allowed. Contact Regal Components AB in case of malfunction.
Sensor
The sensor is simply put a winded coil. Its DC-resistance, which can be measured with a multimeter tool, is
therefore constant and independent of the position. To check the sensor for error measure the resistance
and check that it is in the range of 9 – 100 Ω. Also check that there is insulation between the sensor wires
and the shield or ground of the system.
Control box
If a system is malfunctioning with a sensor that has been tested according instructions above, then it is
probably the controller that is failing.
It is also possible to check that the communication with the sensor works as it should, but this requires an
oscilloscope. With the system running; attach the oscilloscope parallel to the port 6 and 7 at the control
box, same as the two wires from the probe are attached.
- When measuring the DC voltage it should be around 20-40 mV depending on stroke.
- When measuring the AC voltage it should be around 50-300 mV and 5 kHz.
