This will disable the U3606B output, cause the CC
annunciator to flash, and the OC and Error annunciator to
illuminate.
The “triP” message appears on the display after a few
seconds of inactivity.
Resetting the OCP condition
Use one of the following methods to reset the OCP circuit
after it activates. If the condition that caused the
over- current shutdown is still present, the OCP circuit will
turn the output off again.
• When the OCP circuit trips, the U3606B will immediately
prompt you to change the OCP trip level. Use the arrow
keys to select a higher OCP trip level and press [Shift] >
[Save] or [Protect] to save the changes.
• Alternatively, press [Shift] > [Exit] to exit the edit mode
without changing the OCP trip level.
• You may read and clear the error message by accessing
the Utility menu.
If the OCP continues to trip, try lowering the regulated
output current, or raising the OCP trip level.
NOTE
Error number 511, “Current output over protection” will be recorded in the
error queue when the OCP circuit trips. Enter the Utility menu to read and
clear the error message.
NOTE
To protect itself, the U3606B will trip when a large current (over the
system protection values
) is detected, even is the triP option (page 140)
is disabled in the Utility menu.
