3-8. Programming Under Current Limit (UCL)

The encoder switch can change the current from 0A up to the maximum value. If the UCL is active, 
however, the encoder can change the current only from the UCL up to the maximum voltage.

The UCL level values shown below may be different from the actual values.

▌Turn on the power switch.

   After turning on power, check if the unit is in "**OUTPUT OFF**" mode.

▌Since the current limit must be set higher than the set UCL value before setting

 the UCL, the current limit must be set first.

▌When setting the current, use the left cursor key to move the cursor to the 

   desired current range and use the encoder switch to select your desired current.

   The current cannot exceed the protection level if the Protection(OCP/UCL/OCL) 

   settings are active. If you try to exceed the limit in this case, the “PROTECTION 
   LIMIT”  message will be displayed, and the current will be set to the protection level.

▌Press the protection key to set the UCL level.

▌Use the right cursor key to go to the UCL menu.

PROTECT> 5.uCl

▌Press the protection key once more in “protect> 5.UCL.”

UCL SET> 00.00A

▌Use the cursor keys to place the cursor on the desired value.

▌Control the encoder switch to change the level value.

  The UCL level cannot be set higher than the currently outputted voltage
  to prevent operator mistakes.

▌Press the protection key when the change is complete.
