Master Power On
From ATTWiki
Master Power On is the state in which all of the safety stops (E-stops) are cleared and the bender pump is switched on.
In this state, the Master Power On button will illuminate green.
If an E-stop, safety mat, or bend-arm safety plate is tripped, then the electronics in the bender will switch the Master Power OFF.
