SB052: Operating mode selector switch 2 from 6
SB052 is a standard function block designed to monitor the position of
lockable standard operating mode selector switches.
Safe coding is achieved by means of the selection process “2 from 6”.
Coding reduces the number of inputs required.
Operating modes:
• Maximum 15 switch positions possible when 6 inputs are used
• Break-free switchover within the adjustable contact switchover time
Input circuitry:
• Output signals (contacts) from the mechanical operating mode selector
switch
INFORMATION
If possible you should use the PSS(1) DI2 as input module.
If this is not possible, the inputs must use test pulses.
