The “
OCP TRIPPED
” message will be displayed if the actual output current is higher than the OCP
level value, and this stops the source from being displayed based on the output voltage and curre
You can disconnect the DUT and follow the procedure below to clear the trip and allow the unit t
the desired voltage and current once more. A trip may be caused by...
1. Errors in the set OCP level value. Thus, increasing the level value can prevent this problem.
2. Using DUTs with coils or motors that create counter-electromotive force. As shown in Figure < 3-2 >
you can prevent this problem by inserting a UF-diode appropriate for the current capacity.
3. Using the power source as the DUT's power source. If the battery is charging or discharging,
a value higher than the set level value can cause a trip. Inserting a diode appropriate for the current
capacity as in the figure below can prevent this problem.
4. If it is difficult to resolve the trip, you can turn off the OVP feature.
To turn off this feature, switch to factory mode and select “ Disable ” in “ 5.OVP USE .”
▌The LCD will display "
OCP TRIPPED
” if an OCP trip occurs.
▌To clear the OCP trip, start with increasing the OCP level.
Press the protection key to set the level.
Displayed LCD Message
Protect> 1.ovp
▌Use the right cursor key to go to the OCP menu.
Displayed LCD Message PROTECT> 2.OCP
▌Press the protection key once more in “ protect> 2.ocp .”
Displayed LCD Message OCP SET> 50.00a
▌Use the cursor keys to place the cursor on the desired value.
▌Use the encoder switch to increase the level value.
▌Press the protection key when the change is complete.
Displayed LCD Message CHANGED
After the message above is displayed, you will be returned to the state before the
trip occurred.
