Operating mode 1 - Qualified stop
The following functions are active in this operating mode (see chapter 8.2 "Operating mode 1"):
• Qualified stop function
• MaxiScan
• Start/restart interlock active (see chapter 5.1 "Start/restart interlock RES")
The following functions can be selected as well:

NOTICE
The TH timer hold signal from the control must not be generated by inverting the CS switching
signal.
Operating mode 1 is intended primarily for SPG use at lower conveyor speeds (< 0.1 m/s), e.g., in the auto-
motive sector. For an automatic gating end to be possible at speeds up to 0.1 m/s, t2 is set to 2 s.
With the qualified stop function, a normal stop can be performed without interruption of the protective field
even after the CS switching signal was activated.
