Possible Cause
How to Set
1. Press the composite keys [Shift]+[Recall] (Protect) on the front panel to en-
ter the protection menu.
2. Press the up/down key or rotate the knob to select 2. OCP (Off) and press
[Enter].
3. Press the left/right key or rotate the knob to select On and press [Enter] to
enter the setting interface.
4. Set the protection limit Level and the delay time Delay in sequence, and
press [Enter] to confirm.
For bi-directional power supplies, Level can be set to a positive or nega-
tive value, i.e. the same protection limit is set for the output or input
current.
The VFD screen returns to the Protect menu and the OCP setting (take 10A,
1S as an example) is displayed as follows:
PROTECT
2.OCP 10A, 1.000S
Users can enable the OPP function and set the protection limit Level and pro-
tection delay time Delay. When the power (i.e., the Meter value) is greater than
this protection limit and the delay time is exceeded, the power supply will enter
the OPP state.
Many reasons can cause OPP, the details are as follows:
•
The set protection limit Level is lower than the power Meter value.
•
Input too high external power.
•
The power supply outputs a high power due to a fault.
The operation steps to set OPP are as follows.
1. Press the composite keys [Shift]+[Recall] (Protect) on the front panel to en-
ter the protection menu.
2. Press the up/down key or rotate the knob to select 3. OPP (Off) and press
[Enter].
