What to do if the Fincor 2602 fuse blows when AC line power is applied?
- E
  Edward LoveAug 20, 2025
  If the controller fuse blows when AC line power is applied, it could be due to several issues: * Faulty or incorrect wiring. Check all external wiring terminating in the controller and correct accordingly. * A grounded circuit, component, or wiring. Remove the ground fault. * Shorted SCRs or Varistor RV1, or Shunt Field Bridge BR1. Replace the shorted components or the control board. * A shorted or grounded motor shunt field. Repair or replace the motor. * Control board failure. Replace the control board.

Why does the Fincor 2602 Controller fuse blow while the motor is running?
- R
  Ronald RamirezAug 23, 2025
  The controller fuse blowing while the motor is running can be caused by: * An overloaded motor. Check shunt field current; low shunt field current causes excessive armature current. If field current is adequate, check for a mechanical overload. Also, check for a shorted motor armature or incorrect gear ratio, and correct accordingly. * A loose, corroded, faulty, incorrect, or grounded connection or wiring. Inspect all terminals, connections, and wiring between the line, controller, and motor. * A shorted or grounded motor. Repair or replace the motor. * Failing SCRs or Diode D1. Replace shorted devices or the control board. * Control board failure causing SCR false firing or misfiring. Replace the control board.

How to increase the top speed of my Fincor 2602 motor?
- M
  mbenjaminAug 26, 2025
  If the motor won’t reach top speed, consider the following: * Check for rated line voltage, ±10%, on the controller line terminals, as low line voltage can be a cause. * The motor may be overloaded. Check the shunt field current. Low shunt field current causes excessive armature current. If the field current is adequate, check for a mechanical overload. Also check for a shorted motor armature or incorrect gear ratio and correct accordingly. * The maximum speed or current limit may be set too low. Turn the MAX SPD and CUR LMT potentiometers clockwise. * The motor field may be demagnetized. Replace the motor. * Control board failure. Replace the control board.

What causes the Fincor 2602 fuse to blow when starting?
- J
  James BrownAug 28, 2025
  If the controller fuse blows when a Start command is initiated, it could be due to: * Shorted SCRs or Diode D1. Replace shorted devices or the control board. * A shorted or grounded motor. Repair or replace the motor. * Control board failure causing SCR’s to turn-on fully. Replace the control board.

How to fix unstable speed on a Fincor 2602 Controller?
- S
  Sheena DorseyAug 30, 2025
  If you are experiencing unstable speed, consider the following: * Fluctuating AC line voltage. Observe line voltage with a voltmeter or oscilloscope and correct the condition accordingly. * Loose or corroded connections or faulty wiring. Check all terminals, connections, and wiring between the line, operator controls, controller, and motor. * An oscillating load connected to the motor. Stabilize the load; turning the IR/TACH potentiometer counterclockwise may minimize oscillations. * A faulty motor. Check motor brushes, replace if needed, or repair/replace the motor. * A faulty tachometer generator or coupling (if used). Repair accordingly.

How to reduce excessive maximum speed on a Fincor Controller?
- F
  Francis RosalesSep 2, 2025
  To reduce excessive maximum speed: * Turn the MAX SPD potentiometer counter-clockwise, as the maximum speed may be set too high. * Check the motor shunt field and associated circuitry for a loose connection or a broken wire. Repair accordingly. * The motor field may be demagnetized. Replace the motor.

How to decrease the minimum speed of a Fincor 2602?
- D
  Dr. Mark JonesSep 4, 2025
  If the minimum speed is excessive, turn the MIN SPD potentiometer counter-clockwise. Alternatively, the control board may have failed, and you should replace it.

What causes excessive line and motor armature current in a Fincor 2602?
- J
  Joshua KingSep 7, 2025
  Excessive line and motor armature current can be caused by an overloaded motor. Check the shunt field current, as low shunt field current causes excessive armature current. If the field current is adequate, check for a mechanical overload. Also check for a shorted motor armature or incorrect gear ratio, and correct accordingly.

What should I do if the Fincor 2602 Controller motor thermal guard tripped?
- J
  Justin CarrollSep 9, 2025
  If the motor thermal guard tripped, consider the following: * Ensure sufficient ventilation by removing dirt, dust, and debris from the motor intake and exhaust screens. * Reduce the load or increase the speed if there is excessive motor load at low speed. * Check for misalignment and realign the motor, as the motor may be overheating from friction. * Repair or replace the motor if there are shorted motor windings or faulty bearings.

What causes the shunt field current to be too high in my Fincor 2602 Controller?
- C
  Casey BennettSep 12, 2025
  If the shunt field current is too high: * Check the motor rating, as the shunt field may be connected for incorrect voltage. * Measure the shunt field resistance and compare with the motor rating, as the shunt field windings may be shorted. Repair or replace the motor if needed.
