delay: 5 s
Deactivated (normal delivery status)
Activated (on customer demand)
Closing support for -MU
If the DIP-switch is in ON position, the
VM1-T with activated undervoltage release
-MU can be closed even if no voltage is applied
to -MU.
For VM1-T: OFF
Always ON (enables -MO2) in spite of failure
of the microprocessor)
