ERROR CODES
Communications C E If there is any breakdown in communication between the machine controller and the motor
Errorcontroller, “CE” flashes and the unit beeps once. Some common causes of “CE” errors include:
|
|
| • | Conformal coating on serial communications pins between the machine controller |
|
|
|
|
| and motor controller. After disconnecting power to the unit, try scraping this coat- |
|
|
|
|
| ing off the pins. |
|
|
|
| • | Check the resistance values between the serial communications pins with the |
|
|
|
|
| connectors in place. Make sure the harness does not have a bad connection. |
|
|
|
| • | Check the quick disconnect at the motor terminal. The drive motor must be hooked |
|
|
|
|
| up properly or a “CE” error will occur. |
|
|
|
| • | Drive motor thermal protector has opened. |
|
|
|
| • | Motor controller is not powered or fuse has opened. Replace motor controller. |
|
|
|
| Press STOP/CANCEL to clear the display. |
| |
|
|
|
|
|
|
| Long Drain | L d | “Ld” flashes if it takes longer than 5 minutes to pump out water to a point where the operating |
| |
|
|
| pressure switch resets. |
| |
|
|
| Press STOP/CANCEL to clear the display. |
| |
|
|
|
|
| |
| Average Current | C A | If a status signal comes back from the motor controller that a current limit has been breached, |
| |
| Limit | the unit will return to standby mode and display either “CA” for average current limit trip or |
| ||
| “CI” for instantaneous current limit trip. |
| |||
| or | C I | Average current trip occurs if there is a 2 second average of current draw greater than 5.55 |
| |
| Instantaneous |
| |||
| Amps at the motor windings. |
| |||
| Current Limit |
| Instantaneous current trip occurs if there is a spike of 26 Amps instantly at the motor wind- |
| |
|
|
|
| ||
|
|
| ings. |
|
|
|
|
| This may signify problems with the drive motor, thermal protector or motor controller. Over- |
| |
|
|
| loading the unit may cause this problem. |
| |
|
|
| Press STOP/CANCEL to clear the display. |
| |
|
|
|
|
| |
| Off Balance | o b | If the motor controller detects an unrecoverable |
| |
|
| ler will shut down and display an “ob” for off balance. |
| ||
|
|
| The lid switch must be opened at least once before restarting the cycle, if this condition |
| |
|
|
| occurs. Opening the lid will allow the customer to view and redistribute the load. |
| |
|
|
| Press STOP/CANCEL to clear the display. |
| |
|
|
|
|
| |
| Stuck Relay | S r | “Sr” signifies a failure of the relay in the closed position. With this failure, power to the motor |
| |
|
| controller cannot be turned off by the machine controller. |
| ||
|
|
| The machine control board may have a bad relay and may need to be replaced. Check pins |
| |
|
|
| 1 and 5 of P16 of the machine controller and pins 1 and 2 of P1 of the motor controller. This |
| |
|
|
| should have AC line voltage when the motor controller is powered. |
| |
|
|
| Press STOP/CANCEL to clear the display. |
| |
|
|
|
|
| |
| Lid Switch Error | L S | properly. This error code may also be used if there is a disagreement between the motor |
| |
|
|
| The control should flash this error code if it cannot detect the lid switch opening and closing |
| |
|
|
| and machine controllers on the state of the lid switch. The control should not allow the unit |
| |
|
|
| to run in this condition. |
| |
|
|
| This code will also appear if the user presses the START key while the lid is open. |
| |
|
|
| Open the lid or press STOP/CANCEL to clear the display. |
