Operational Procedure
The machine operator should not use the SLS to perform a normal stop
function. The SLS should only be used to isolate the system. Machine access is
allowed only after the SLS switch is locked and tagged in the OFF position and
the white SAFE light is illuminated to verify that the system is indeed isolated.
If the white SAFE light fails to illuminate when the SLS switch is turned to the
OFF position, the machine cannot be considered isolated nor safe. The
operator should not enter the machine, but should contact a SLS qualified
service technician.
