TROUBLESHOOTING
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 for the time specified on the drive warning label, 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 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.
7.1 Fault Codes
Fault codes are indicated on the graphic display. See Table 29 for a list of fault codes.
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 4.2, 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 of fault
occurs, the display will read NO AUTO RESTART. Refer to Table 29, 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 or by pressing both arrow keys for 3
seconds.
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.
