Operating Principle
This is a dual channel system with monitoring of the contactors. It uses 2 double pole (N.C. & N.O.) positive mode momentary action push
switches.
The motor can only be started when both buttons are pushed synchronously (within 0.5 sec.). If either or both buttons are released, the
outputs at the Minotaur are opened.
