The signal from MP17 is fed back into the CR30 safety relay at terminal 9. This
signal is used as part of the logic to turn on the reset indicator. We want the reset
indicator to turn ON when the contactors are OFF.
This application note assumes that the MAB lock module has been taught to
re
cognize its handle assembly.
The MAB internal switch settings are:
1. ON
2. ON
3. OFF
4. OFF
5. OFF
6. ON
