7. Maintenance
Maintenance is limited to cleaning the sensor as a routine maintenance task. The sensor must be thoroughly
cleaned ensuring that no particles have adhered to the rod as this could create a conductive path to ground.
There is no maintenance required for the transmitter.
8. Warranty
Warranty is for one (1) year. It starts from the delivery date. The warranty is valid as long as the system has
been installed and commissioned according to the Operating Instructions and there is no sign of any wear
or mechanical damage.
In the case of defects during the warranty period, all defective components will be repaired / replaced.
The parts that are replacing the defective parts, remain the property of SWR. If the costumer requires the
warranty work to be executed at their premises, then the costumer will pay for costs of the SWR engineer to
be on their site.
SWR is not responsible for any damage to the customer’s process and is not responsible
for any loss of profit due to that damage.
9. Troubleshooting
9.1 Alarm relay does not work
1. Check power supply and terminal connections.
2. Check parameter for alarm setting, are all time settings correct?
9.2 No measured value, even so after calibration
1. Check whether the process is running in a normal condition and whether there was normal conditions
during calibrating. Check if there was a real zero condition during zero calibration and that there was a
normal dust load during the interpolation point calibration.
2. If using the software: Has there been raw values displayed during the calibration procedure?
3. Check power supply and cabling.
4. Check for conductive and/or a short-circuit conditions between the sensor rod and the duct wall.
Also check for any particles sticking to the sensor rod or any condensation surrounding the sensor rod.
If the unit still fails the before mentioned checks, please your local distributor or contact
SWR engineering Messtechnik GmbH directly.
