DANGERS
When Designing your GLC System:
• Be sure to design your GLC control system so that, in the
event of a main power supply failure or a GLC accident, the
user system’s overall safety integrity will be maintained. If
this is not done, incorrect output signals or a GLC mal-
function may cause an accident.
(1) Interlock and other circuits designed to interrupt or op-
pose normal machine movement (such as Emergency
Stop, General Protection, and forward and reverse rota-
tion), as well as those designed to prevent machine dam-
age (such as upper, lower, and traverse movement limit
positioning) should all be designed to be located out-
side of the GLC.
