Troubleshooting Troubleshooting AutoDRIVE This section provides information on fault codes and troubleshooting tips for potential system problems. WARNING! In some instances, the unit will shut down, then automatically restart when conditions allow. Always disconnect input power from the unit and wait for internal electrical charges to dissipate before performing service on the unit or its connected loads. WARNING: Risk of electric shock. De-energize the unit by disconnecting all incoming sources of power, then wait 10 minutes for internal charges to dissipate before servicing the equipment. HIGH VOLTAGE: This equipment is connected to line voltages that can create a potentially hazardous situation. Electric shock could result in serious injury or death. This device should be installed and serviced only by trained, licensed and qualified personnel. Follow instructions carefully and observe all warnings. Always check the LCD display for fault codes if the drive or its load is not operating. Disconnecting the input power could potentially clear any fault code indication, possibly losing valuable information for troubleshooting. Fault Codes Fault codes are indicated on the graphic display. The drive can be programmed to automatically restart after certain faults and a time delay can be programmed before the restart is allowed. To interrupt a time delay countdown and allow auto restart, press both arrow keys on the keypad and hold for one second. The load will start immediately. The Restart Log is a resettable fault log that can be used to monitor faults that allow auto restart. Use the Clear Memory function to reset the Restart Log and set all fault counters to zero. See Section 4.4, pg. 17, Keypad Main Menu Items, for more information on Restart Log and Clear Memory function. WARNING: Certain faults do not allow an auto restart. These faults generally indicate the possibility of damage to the drive and/or the load, or indicate the possibility of a dangerous condition. When this type fault occurs, the display will read NO AUTO RESTART. Refer to Table 16, pg. 50, Fault Codes, to determine if the fault allows an auto restart. The number 1 in the notes column indicates that auto restart is not allowed. When this type of fault occurs, contact the factory for assistance before restarting or troubleshoot the system thoroughly. These faults can be cleared only by cycling input power OFF/ON. WARNING: Unit may restart automatically without warning after a fault when operating conditions permit. Make certain input power is disconnected before servicing the unit or its connected loads. Clearing a Fault If the unit is programmed to automatically restart after a particular fault, the display indicates that the unit will restart and will count down the seconds remaining to restart on the display. The countdown can be interrupted by pressing and holding both arrow keys. The load will immediately restart. For faults that allow an automatic restart, the default number of restarts after a fault is zero. If the end user desires the unit to automatically restart after a fault, the number of restarts allowed and the time between fault and restart must be programmed in the CHANGE PARAMETER VALUES > AUTO RESTART PARAMETERS for that fault. If the drive has exceeded the programmed number of auto restarts, or if auto restarts have not been enabled, the display will indicate the fault on the top line and the second line will read RESTART? ENTER. Press ENTER to clear the fault and restart the load. The fault counters in the Restart Log will all be reset to zero. The ENABLE RESTART parameter allows the drive to restart automatically after a fault. This parameter also enables the drive to initialize in AUTO mode when the input power has been cycled OFF/ON and the drive is energized. The factory default setting does not allow auto restarts. Navigate to this parameter via CHANGE PARAMETER VALUES > AUTO RESTART PARAMETERS > ENABLE RESTART. There are several conditions where the drive will indicate a fault but the fault will not be recorded in the fault log. These faults occur only when the drive is energized from utility mains and is initializing. If any of three conditions including ground fault, high input voltage or low input voltage is detected, the display will indicate the fault and wait for the condition to resolve before entering normal operating mode. If these conditions occur after the drive has initialized, a fault will be logged and can be cleared in the normal manner. 3/26 800-356-5130 | [email protected] | bakerwatersystems.com 361 Troubleshooting
