*1 NPN is the setting for these terminals. No external power supply is required. Refer to connections shown below
*2 Functions in parentheses are default settings.
Selecting Input Method
Switches SW7and SW8, both of
which are located above the cont-
rol circuit terminals, are used for in-
put method selection.
Remove the front cover and optio-
nal cover to use these switches.
Selecting Sequence Input Method
By using SW7, NPN or PNP input can be selected as shown below
