Sam
my old c-frame machines were all wired with an i/o box at rear of column
this box had 2 rows of terminal strips
top was in from control
bottom was out to control
terminal 1 of top jumpered to terminal 1 of bottom allowed override of 
the whole estop chain on machine side ( temperature, oil overflow, 
limts, etc )
I never went as far as installing an override switch though, thought 
that was risky
the jumper was useful when initally installing
( techs never set the tachos to agree with the motor command polarity )

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
