Why does my EME FINCOR 2230 MKII Controller line fuse blow when AC line power is applied?
- T
  thomasamandaAug 15, 2025
  The controller line fuse might blow due to faulty or incorrect wiring. Inspect all external wiring connected to the controller and correct any issues. It could also be due to a grounded circuit, component, or wiring, which requires removing the ground fault. Other potential causes include shorted SCRs, a shorted varistor RV1, shorted Shunt Field Diodes (D39, D40, D41, or D42), or a shorted or grounded motor shunt field. In these cases, replace the shorted components or repair/replace the motor. A control board failure can also cause this issue, necessitating replacement of the control board.

What to do if the EME FINCOR 2230 MKII motor won’t start?
- V
  Victor HansenAug 18, 2025
  If the motor won’t start, ensure the rated AC line voltage is applied to the controller. Check the operator controls for proper function and correct connections. Try resetting the controller by issuing a Stop command followed by a Start command. Verify that +24 VDC is applied to Terminal TB2 8 and check for a 0 - ±10 VDC speed reference signal. Also, make sure the FWD CUR LMT and REV CUR LMT potentiometers are turned clockwise. Check the motor shunt field and associated circuitry for loose connections or broken wires. If these steps don't resolve the issue, the motor itself may have failed, or the control board may need replacement.

Why does the EME FINCOR 2230 MKII line fuse blow when starting?
- A
  Ana BryantAug 21, 2025
  The controller line fuse may blow upon initiating a start command due to a shorted SCR. Replace the shorted device or the control board. Another cause could be a shorted or grounded motor, which would require repairing or replacing the motor. A control board failure causing the SCRs to turn on fully can also lead to this issue, necessitating replacement of the control board.

What causes excessive line and motor armature current in the EME Controller?
- B
  Breanna BradfordAug 25, 2025
  Excessive line and motor armature current is often caused by a motor overload. Check the shunt field current, as low shunt field current can lead to excessive armature current. If the field current is adequate, inspect for a mechanical overload. Ensure the unloaded motor shaft rotates freely and check the motor bearings. A shorted motor armature or an incorrect gear ratio can also cause a motor overload. Correct any of these issues accordingly.

Why does the EME Controller line fuse blow while the motor is running?
- R
  Robert ZavalaAug 27, 2025
  If the controller line fuse blows while the motor is running, the motor may be overloaded. Check the shunt field current; low shunt field current can cause excessive armature current. Also check for a mechanical overload or a shorted motor armature. Loose or corroded connections, faulty wiring, or a shorted motor can also cause this issue. Inspect all terminals, connections, and wiring between the line, controller, and motor. In addition, one or more SCRs may be breaking down. If so, replace the faulty devices or the control board. The control board itself might be causing SCR false firing or misfiring, requiring its replacement.

How to fix unstable speed on EME FINCOR 2230 MKII Controller?
- S
  Stephanie PenaAug 30, 2025
  Unstable speed in the EME Controller can be caused by several factors. Fluctuations in AC line voltage can be a cause; observe the line voltage with a voltmeter or oscilloscope and correct any fluctuations. Loose or corroded connections, or faulty wiring can also contribute; check all terminals, connections, and wiring between the line, operator controls, controller, and motor. If the load connected to the motor is oscillating, stabilize it. A faulty motor can also cause unstable speed; check the motor brushes and replace if needed, or repair/replace the motor. Also, a faulty tachometer generator or coupling (if used) can be the cause.

What causes the EME Controller motor not to reach top speed?
- C
  Casey HoltSep 2, 2025
  If the motor won’t reach top speed, check for rated line voltage, ±10%, on the controller line terminals. The motor may be overloaded, so check the shunt field current. Low shunt field current causes excessive armature current. If field current is adequate, check for a mechanical overload. Also, turn the MAX SPD potentiometer clockwise and the FWD and REV CUR LMT potentiometers clockwise. If these steps don't resolve the issue, the motor field may be demagnetized, or the control board may have failed.

What causes low shunt field current in the EME FINCOR 2230 MKII Controller?
- S
  Sarah MccormickSep 5, 2025
  Low shunt field current can be caused by an open shunt field winding or wiring to the motor shunt field. Check the motor shunt field and associated circuitry for a loose connection or a broken wire. Also, the shunt field may be connected for the incorrect voltage; check the motor rating. A failure of Diode D39, D40, D41, or D42 can also cause this issue; replace the faulty diode or the control board.

What causes high shunt field current in the EME Controller?
- V
  Vicki PhelpsSep 8, 2025
  High shunt field current can occur if the shunt field is connected for the incorrect voltage. Check the motor rating. Also, shunt field windings might be shorted; measure the shunt field resistance and compare with the motor rating. If windings are shorted, repair or replace the motor.

What to do if EME FINCOR 2230 MKII Controller motor thermal guard tripped?
- R
  Robert AndrewsSep 12, 2025
  If the motor thermal guard tripped, start by ensuring sufficient ventilation by removing dirt, dust, and debris from the motor intake and exhaust screens. If the motor load is excessive at low speed, reduce the load or increase the speed. Check for misalignment and realign the motor if necessary. Shorted motor windings or faulty bearings can also cause overheating, so repair or replace the motor if needed.
