Protection
LF Series has various protection modes. (OVP, OCP, OPP, OTP) 
Below are explanation about each pretection mode.

OVP means "Over Voltage Protection".
If load outputs more voltage than its capacity, protection will be on 
and "OVER VOLT PORT" will be displayed.
To disable OVP, set the voltage of power supply according to
load's spec and press ESC & ERR/PROT KEY for 2~3 seconds.
OCP means "Over Current Protection".
If load outputs more current than its capacity, protection will be on 
and "OVER CURR PORT" will be displayed.  
To disable OCP, press ESC & ERR/PROT KEY for 2~3 seconds.
OPP means "OVER WATT PROTECTION". If load outputs more power than
its capacity, Protection will be on and "OVER WATT PORT" will be displayed.
To disable OPP, set the power of load according to
load's spec and press ESC & ERR/PROT KEY for 2~3 seconds.

OTP means "Over Temperature Protection". If heatsink's temperature is
more than 100

℃

, Protection will be on and "OVER TEMP PORT" will be

displayed. To disable OTP, stop operating load and cool down the load.
To disable OTP, press ESC & ERR/PROT KEY for 2~3 seconds 
when the temperature is less than 100℃.

OVR means "Over Voltage Rang". If load outputs more voltage than
its capacity in CV LOW Rang, Rang Over will be on and "VOLT RNG OVER"
will be displayed. To disable OVR, set the voltage of power supply
according to load's voltage LOW Rang spec or set load's voltage Rang
as HI and press ESC & ERR/PROT KEY for 2~3 seconds.

OCR means "Over Current Rang". If load outputs more current than
its capacity in OV LOW RANG, Rang Over will be on and "CURR RNG OVER"
will be displayed.To disable OCR, set load's current Rang as HI and
press ESC & ERR/PROT KEY for 2~3 seconds.
