Enabling and disabling emission
Procedure 3 Turning on the laser using CONTROL
Action

is RED and Status is AMBER, check the
following:
a. The door interlock circuit is open –
Connecting the safety interlock on page 91
b. The external bus is not looped back with a
bus defeater – Connecting the safety

remains RED, even if the interlock circuit is
closed, pressing the Emission button will clear
the interlock when Emission is enabled. (See
the next step: 4.)

once.
