5. Troubleshooting and Remedies
5.1 Response of the measuring system to faults
•
Error messages which occur during measurement are always indicated via the
current and, depending on the preset relay function, also via the relay output.
•
In addition, a system or process error is always indicated when the red LED flashes.
5.2 Checking the electronics
The Magphant can be set to a test mode using miniature switch No. 1:
1. Set test mode switch to "test".
2. Turn the full-scale potentiometer anticlockwise until it comes to the mechanical
stop, the current output must now be exactly 20 mA.
3. If this is not the case, then the electronics module must be replaced.
