4 Advanced Operation
4-2
4-3 Turning Output ON/OFF with the Remote Switch
Remote switch enable to turn ON/OFF the output.
(The front panel OUTPUT switch must be ON)
When LD on front panel is displayed, there is no output(Remote switch is OFF)
When LD on front panel is not displayed, power supply is enable to output
(Remote switch is ON)
This function can be executed with the following 2 methods.
Method ② is recommended in case there is possibility of noise coming in from
outside onto the wiring (for example there is repeatable short circuit at load end).
①
Independent operation or separate contacts of the external relay available for the
individual units
TTL LOW = OUTPUT : ON
TTL HIGH = OUTPUT : OFF
Or
External relay CLOSED = OUTPUT : ON
External relay OPEN = OUTPUT : OFF
② Turning ON/OFF with power supply units serially connected
PINs 4 and 8 can be used floating (-S (common) to 100 V).
5Vdc ON = OUTPUT : OFF
5Vdc OFF = OUTPUT : ON
③ To make ON/OFF of ① and ② to OFF/ON (to reverse the logic)
To make ① OFF/ON, apply 5 V between PINs 8 and 4.
To make ② OFF/ON, OPEN the jumper between the PINs 10 and 21. When 5 V is
applied
between PINs 8 and 4, it is turned ON. Stopping application of 5 V turns it OFF.
