What to do if my Solcon RVS-DX Controller trips with an O/C SHEAR error?
If the Solcon Controller trips due to an O/C SHEAR fault, it means the current instantaneously exceeded 8.5 times the Starter FLC. First, verify the motor is properly installed and not jammed. Then, check the FLA and FLC settings. After that, inspect the motor and cable connections. Finally, perform a “Megger” test to assess the condition of the motor and cable.
Why does my Solcon Controller trip due to OVERLOAD?
If your Solcon Controller trips due to an OVERLOAD, it means the current exceeded the OVERLOAD TRIP level and the thermal register has filled up. You should check the FLA, FLC, and Overload settings. Also, check the motor current and wait 15 minutes to allow the motor and starter to cool down before restarting.
What does it mean when my Solcon RVS-DX Controller trips with O/C or WRONG?
If the Solcon RVS-DX trips due to O/C or WRONG, it indicates a wrong connection inside Delta or an overcurrent detection. Verify that the motor is not stalled or shorted, and check the cables and wiring. Also, ensure that the motor and RVS-DX are connected exactly as shown in section 4.3.9.2 page 13. If the circuitry is confirmed to be 100% correct, you can start when WIDER SETTINGS are ENABLED.
How to fix a PHASE LOSS trip on my Solcon RVS-DX?
If the Solcon Controller trips due to PHASE LOSS, it means one or two phases are missing. Check that the voltages are within the required range and the frequency is within the range of 45-65Hz. If all previous actions do not solve the problem and you are sure that no real phase loss exists, you can set PHASE LOSS Y/N protection to NO.
What causes an UNDER/NO trip on a Solcon RVS-DX and how to resolve it?
If the Solcon Controller trips due to UNDER/NO, it means the line voltage dropped below the preset level for the preset time. Check the UNDER VOLTAGE TRIP and TIME DELAY settings, and verify the line voltages on L1, L2, L3.
Why does my Solcon Controller show an OVER voltage trip?
If the Solcon Controller trips due to OVER, it indicates that the line voltage increased above a preset level for a preset time. Check the OVER VOLTAGE TRIP and TIME DELAY settings, and verify the line voltage on L1, L2, L3.
What to do if Solcon Controller trips due to TOO MANY starts?
If the Solcon Controller trips because of TOO MANY trips, it means the number of starts during the START PERIOD exceeded the preset STARTS number. Wait until the motor and starter cool down – according to the START INHIBIT setting.
Why is my Solcon RVS-DX Controller tripping with a LONG START error?
If the Solcon Controller trips due to a LONG START, it means the output voltage did not reach nominal at the present MAX. START TIME. Check the FLA, FLC, and MAX START TIME settings. Increase the INITIAL VOLTAGE, CURRENT LIMIT & MAX. START TIME or decrease the ACCELERATION TIME as necessary.
How do I resolve a PHASE trip on my Solcon Controller?
If the Solcon Controller trips due to PHASE, it means the line phase sequence is wrong. Check the line phase sequence, and if it is wrong, swap two wires on the line side.
What does an UNDER current trip indicate on my Solcon RVS-DX?
If the Solcon Controller trips due to UNDER, it means the line current dropped below the preset level for the preset time. Check the UNDER CURRENT TRIP and TIME DELAY settings, and verify the line currents through L1, L2, L3.
