 Using the Timer Function
The multi-function digital input terminals S3 to S7 can be used as timer function input terminals, and
multi-function output terminals M1-M2 and M3-M4 can be used as timer function output terminals. By setting
the delay time, you can prevent chattering of the sensors and switches.
• Set one of the constants H1-01 to H1-05 (multi-function contact input terminal S3 to S7) to 18 (timer func-
tion input).
• Set H2-01 or H2-02 (multi-function output terminals M1-M2 and M3-M4 function selection) to 12 (timer
function output).
