Controlling the safety functions
7.3 Control of "STO" and "SS1" via terminals on the Control Unit and the Motor/Power Module
Safety Integrated
172 Function Manual, 05/2010, A5E03264275A
NOTICE
An open input is interpreted as "low".
To enable the digital inputs (DI) to function, terminal M1 must be connected.
This is achieved by:
1. Providing the ground reference of the digital inputs, or
2. a jumper to terminal M.
Caution! This removes the electrical isolation for these digital inputs.
Note
If a momentary interruption in the voltage occurs in the 24 V supply, the digital outputs will be
deactivated until the interruption has been rectified.
