Resetting the OVP condition
Use one of the following methods to reset the OVP circuit after it
activates. If the condition that caused the overvoltage shutdown is still
present, the OVP circuit will turn the output off again.
1 When the OVP circuit trips, the U3606A will immediately prompt you to
change the OVP trip level. Use the directional keys to select a higher
OVP trip level and press Shift > Save or Voltage (Protect) to save the
changes.
2 Alternatively, press Shift > Exit or Shift > Protect to exit the edit mode
without changing the OVP trip level.
3 You may read and clear the error message by accessing the utility
menu. See “Reading error messages” on page 114 for more information.
4 Press to turn the output on.
5 If the OVP continues to trip, try lowering the regulated output current,
or raising the OVP trip level.
