What causes a mains current imbalance greater than 3% in a Danfoss Media Converter?
If the mains current imbalance is greater than 3% on your Danfoss Media Converter, and the imbalanced leg follows the wire, it indicates a power problem. Check the mains power supply. If the imbalance leg stays on the same input terminal, it suggests a problem with the unit, in which case you should contact your supplier.
What does it mean when motor current imbalance is greater than 3% on Danfoss Media Converter?
If the motor current imbalance is greater than 3% in your Danfoss Media Converter, and the imbalanced leg follows the wire, the problem is in the motor or motor wiring. Check the motor and motor wiring. If the imbalance leg stays on the same output terminal, it indicates a problem with the unit, and you should contact your supplier.
How to troubleshoot a dark or non-functional display on a Danfoss Media Converter?
If the Danfoss Media Converter display is dark or not functioning, first check the input power source. Then, check for any missing or open fuses or tripped circuit breakers. If the issue persists, the LCP may not be receiving power, in which case you should replace the faulty LCP or connection cable. Also, check for any shortcuts on the control voltage or at the control terminals and ensure proper wiring. Confirm that you are using the correct LCP model (LCP 101 (P/N 130B1124) or LCP 102 (P/N. 130B1107)). Adjust the contrast by pressing [Status] + Up/Down arrows. If the display is still defective, replace the LCP or connection cable. For internal voltage supply faults, contact your supplier.
What to do if the motor is not running with my Danfoss Media Converter?
If the motor is not running on your Danfoss Media Converter, start by connecting the motor and checking the service switch. Ensure mains power is applied, especially if using a 24V DC option card. If the LCP is stopped, press [Auto On] or [Hand On] to run the motor, depending on your operation mode. Also, verify that a valid start signal is applied and that the motor coast signal is not active by applying 24V on terminal 27 or programming this terminal to No operation. Finally, check the reference signal source and program the correct settings.
Why does the Danfoss Media Converter open power fuses or trip the circuit breaker?
If the Danfoss Media Converter experiences open power fuses or a circuit breaker trip, check for and eliminate any phase to phase shorts. Perform a startup test to verify the motor current is within specifications. If the motor current exceeds the nameplate full load current, reduce the load. Also, tighten any loose connections.
What causes an intermittent display on a Danfoss Media Converter?
If the Danfoss Media Converter display is intermittent, it may be due to an overloaded power supply (SMPS) caused by improper control wiring or a fault within the frequency converter. If the display stays lit, check the wiring for shorts or incorrect connections. If the display continues to cut out, follow the procedure for a dark display.
How to fix a Danfoss Media Converter motor running in the wrong direction?
If the motor is running in the wrong direction with your Danfoss Media Converter, program the correct settings for motor rotation limits. Deactivate any active reversing signals. Refer to section 3.5 in the manual to check the motor rotation.
