Clearing The Error Code - Advanced Energy Pinnacle 20 kW Manual

If you cannot identify the problem by following this checklist, please call AE Global Support.
If the unit's front panel or Pinnacle Remote Active Panel displays an error code, see "Error
Code Troubleshooting Table" on page 7-8. To reset the unit's user-selectable parameters to the
factory defaults, read about the default function in the "I/O Communication and Control"
chapter.)

Clearing the Error Code

Error codes are typically generated by two types of faults: self-clearing or explicit clear. When
the unit experiences a self-clearing fault condition, the unit turns off output and displays an
error code on the panel. When the fault condition is no longer present in the system, the panel
ceases to display the error code. (You then can turn on the output.)
When the unit experiences an explicit-clear fault condition, the unit turns off output and
displays an error code. Once the fault condition is no longer in the system, you must
acknowledge the condition from your controlling interface before turning on output.
To reset the Pinnacle unit, do one of the following:
• From the front panel, press the OFF button to acknowledge the condition. Then press the
ON button to turn on output.
• Through the DeviceNet interface, send the Poll Command message twice: once to turn off
output and once to turn on output (see the description of Byte 4).
• Through the AE Bus interface, serial port or Profibus interface send the OFF command,
then send the ON command to turn on output.
• Through the User port interface, release and reestablish closure between pins 4 and 9 to
turn off and on the output.
