The MC3 controller will energize relays whenever the mat is clear, and de-
energize whenever it has been stepped upon. During both power up and normal
operation, an ON-delay of approximately 1/10 to 2/10 second is normal. The
RUN indicator will follow the MAT CLEAR light.

The MC3 controller will interlock in de-energized state both upon application
of power and also whenever the mat is stepped upon. Requires a manual reset
operation to cause the system to energize relays. The MAT CLEAR light will
indicate that it is possible to activate the start switch and enter into the
MACHINE RUN state. The controller attempts to enter the RUN STATE upon
the release of the start switch. Press and hold the start switch for more than
0.15 seconds. The safety mat area must be clear at the time the start switch is
pressed and released.
