4. Pin6 and Pin18 are the input pins of TTL Level and are able to set the initial state to
logic: ON=HIGH or OFF=LOW.
5. When the DC power supply is set to OUTPUT = ON, the detail actions of REMOTE
INHIBIT are shown in Figure 3-84.

Ext. ON/OFF function allows users to control the DC power supply’s output through the Pin 6
& 18 (_EXT_ON) of ANALOG INTERFACE.
1. Tap EXT ON/OFF to set DISABLE and ENABLE;
(1) Selecting DISABLE: Turns output off.
(2) Selecting ENABLE: Sets EXTERNAL ON/OFF to ENABLE and make the “ ”
invalid, also the Pin 6 & 18 (_EXT_ON) replaces the “ ” to control the power
supply’s ON/OFF. When the Pin 6 & 18 (_EXT_ON) voltage level of ANALOG
INTERFACE turns to HIGH, the power supply is unable to output, that is OUTPUT =
OFF. When the Pin 6 & 18 (_EXT_ON) voltage level turns to LOW, the DC power
supply outputs normally, that is OUTPUT = ON.
2. When the EXT. ON/OFF is enabled, the MAIN page will appear the EXT message.
Moreover, Pin 6 & 18 are the input pins of TTL Level and are able to set the initial state
to PULL=HIGH or PULL=LOW.
3. When the DC power supply is set to OUTPUT = ON, the detail actions of EXTERNAL
ON/OFF are as shown in Figure 3-85.
