What to do if my Solcon RVS-DN 8 displays COMM. PORT FAILED?
If your Solcon Controller displays COMM. PORT FAILED, reconnect the wiring and/or the communication with the PLC and wait for a start command initiated by the PLC.
What should I do if my Solcon RVS-DN 8 displays O/C – SHEAR PIN?
If the Solcon Controller shows an O/C – SHEAR PIN error, make sure that the motor isn't stalled or jammed. Check the FLA and FLC settings. Inspect the motor and cable connections. Perform a 'Megger' test to verify the condition of the motor and cable.
What does it mean if my Solcon Controller displays PHASE LOSS?
If your Solcon Controller indicates a PHASE LOSS: 1) Ensure the current transformers are not grounded. 2) Check phase voltages related to terminal 21. 3) Verify terminal 21 is correctly connected. 4) If correctly connected, disconnect terminal 21 and attempt to start. 5) If the issue persists, set PHASE LOSS Y/N protection to NO. Note that doing so means the motor will single phase if a true PHASE LOSS occurs. 6) Be aware that phase loss might not be detected in motor operating under a light load.
What does it mean if my Solcon Controller displays OVER VOLTAGE?
If your Solcon Controller is showing an OVER VOLTAGE error, check the OVERVOLT. TRIP and OVERVOLT. DELAY settings. Also, check the line voltage on L1, L2, and L3.
What to do if my Solcon Controller displays UNDER VOLTAGE?
If your Solcon Controller displays an UNDER VOLTAGE error, check the UNDERVOLT. TRIP and UNDERVOLT. DELAY settings. Also, check the line voltages on L1, L2, and L3.
What to do if my Solcon RVS-DN 8 Controller displays WRONG PARAMETERS?
If your Solcon Controller displays WRONG PARAMETERS, after loading a new software version or after powering up, press Reset, then Mode and ? simultaneously. Save the default parameters by pressing Store and Mode simultaneously.
What to do if my Solcon RVS-DN 8 displays SHORTED SCR?
If your Solcon Controller displays SHORTED SCR, check with an ohmmeter between L1-U, L2-V, L3-W; resistance should be greater than 20 KOhms. Also, check for no voltage on terminals U, V, W.
What to do if my Solcon Controller displays EXTERNAL FAULT?
If your Solcon Controller displays EXTERNAL FAULT, check the contact position and the cause of closure.
What should I check if my Solcon RVS-DN 8 shows an INSULATION TRIP?
If your Solcon Controller displays an INSULATION TRIP, check the motor and cable insulation level.
What does it mean if my Solcon RVS-DN 8 displays TOO MANY STARTS?
If your Solcon Controller shows a TOO MANY STARTS error, wait until the motor and RVS-DN cool down. The cool-down period is determined by the NUMBER OF STARTS, STARTS PERIOD, and START INHIBIT settings.
