What causes OPEN BYPASS trip after start process in Solcon HRVS-DN?
An OPEN BYPASS trip after the start process in the Solcon Controller can be caused by: * Verify that Current Gain dip switches are set according to the ratio between the rated current of the starter and the testing motor rated current. * Check Bypass Contactor wiring.
How to fix incorrect current reading on Solcon HRVS-DN Controller's panel?
To address an incorrect current reading on the Solcon Controller's panel: * Verify that the HRVS-DN FLC setting parameter is set according to the rated current of the starter. * Check the Current Gain dip switches settings. If both Gain dip switches of phases are set to on, the gain = 1. If Gain dip switches # 1 of phases are set to off, the gain = 5. If Gain dip switches # 2 of phases are set to off, the gain = 13.4. If both Gain dip switches of phases are set to off, the gain = 67. * Use a Clamp-on the Ammeter to measure test the motor current. * The starter’s current reading should be approximately the actual current multiplied by the gain ratio set by the Gain dip switches. * You can also set parameters to default parameters and re-program the HRVS-DN.
Why does Solcon Controller motor vibrate at the end of starting or beginning of soft stop?
If the motor vibrates mechanically at the end of the starting process or at the beginning of a soft stop, and the current fluctuates with the Solcon Controller: * This phenomena may occur with unloaded or lightly loaded motor, if SOFT START CURVE 0 is used. * Use standard curve SOFT START CURVE 1 and SOFT STOP CURVE 1.
How to troubleshoot UNBALANCE CURRENT trip after starting Solcon Controller?
To troubleshoot an UNBALANCE CURRENT trip after starting the Solcon Controller: * Verify, by reading currents on the display, that the three current readings are identical (before the trip). * Check that fiber optic wires 1, 3 & 5 are properly connected to the Control Module. * Check that the current Gain dip switches are set identically in the three phases. * Verify that current flows in all three phases. * If there is no current display on one phase: * Change to SOFT START CURVE 0 (basic). * Try to start. * If the problem still exists perform a firing test.
What causes PHASE LOSS trip in Solcon Controller after starting?
A PHASE LOSS trip after starting the Solcon Controller may be caused by: * Verify that all three phases are within range. * Verify that EPT-Tx and EPT-Rx fiber optic wires are properly connected. * If low voltage mains is powered from a generator, check that frequency is within the range of 46Hz < f
How to fix TOO MANY STARTS trip on Solcon HRVS-DN Controller?
If a TOO MANY STARTS trip occurs immediately after starting the Solcon Controller: * The default setting allows for one start per 20 minutes. * To reset the fault find the NUMBER OF STARTS setting at the end of the START PARAMETERS page, increase setting to OFF, then reset. Store at the end of the page. * Be sure to set for medium voltage operation after end of testing.
What to do if PWR ON & NO STRT Trip occurs before starting Solcon Controller?
The PWR ON & NO STRT Trip occurs before starting the Solcon Controller when mains voltage is connected to the HRVS-DN for more than 30 seconds without a start signal. It may also occur if mains voltage is connected downstream (“below”) from the Line Contactor instead of upstream (“above”) the Line Contactor. The starter protects itself from overheating. This function can be disabled for special applications.
Why does O/C-SHEAR PIN trip occur when starting Solcon Controller?
An O/C-SHEAR PIN trip immediately after starting the Solcon Controller could be due to: * Verify that Current Gain dip switches are set according to the ratio between the rated current of the starter and the testing motor rated current. * The trip can occur if added (by setting of Gain dip switches) gain is too high. * Try to start with SOFT START CURVE 0 and stop with SOFT STOP CURVE 0. If problem is solved the current transformers and their wiring should be checked. * Check that all fiber optic wires are properly connected.
What causes GROUND FAULT trip after starting Solcon Controller?
A GROUND FAULT trip after starting the Solcon Controller may be due to: * View the three currents on starter’s display. * Check that the current Gain dip switches are set identically in the three phases. * Verify that an output cable to the motor is not short circuited to the chassis ground. * Verify that two wires of a CT are not swapped (can occur only if user changed CTs wiring! ) Note: SUCH ACTION WILL VOID MANUFACTURER’S WARRANTY ! * Disconnect the low voltage motor. Check motor insulation with a Megger tester.
How to resolve PHASE SEQUENCE trip in Solcon HRVS-DN Controller?
If a PHASE SEQUENCE trip occurs immediately after starting the Solcon Controller, it indicates that the phase sequence of the mains lines is incorrect. You have two options to resolve this: 1. Swap two input lines. 2. Set the PHASE SEQUENCE setting in FAULT PARAMETERS as required.
