Note 1. Parameter settings can be used to select various functions for multi-function inputs 1 to 7,
multi-function contact outputs, and multi-function photocoupler outputs. The functions in
parentheses are the default settings.
Note 2. NPN is the default setting for these terminals. Wire them by providing a common ground. No
external power supply is required.
Note 3. To provide an external power supply and wire the terminals through a common positive line,
set SW1 to PNP and use a 24 V DC ±10% power supply.
