Automatic Start:
as the detection zone is clear of opaque objects of the specified size.
Detection Zone:
the ESPE must detect its presence and set its safety outputs to the OFF-state.
Electro-Sensitive Protective Equipment (ESPE):
together for protective tripping or presence sensing purposes and comprising as a minimum:
• a sensing device
• controlling/monitoring devices
• output signal switching devices
LOCKOUT Condition:
to the OFF state and the ESPE will not attempt to leave this state without performing a comprehensive
power-up self-test. A power-up self-test will be initiated by either cycling the ESPE power or by a Start
signal transition.
MACHINE RUN:
MACHINE RUN LED is on, the Red MACHINE STOP LED is off and the Yellow INTERLOCK LED
is off.
MACHINE STOP:
MACHINE RUN LED is off, the Red MACHINE STOP LED is on.
OFF-State:
ON-State:
Output Signal Switching Device (OSSD):
disable the guarded machine.
Response Time:
OFF-state once the detection zone is blocked by an opaque object of the specified size.
Start INTERLOCK:
Start signal transition must occur before going to MACHINE RUN for the first time. Once the first
Start condition has been met, the ESPE will operate in the Automatic Start mode.
Start/Restart INTERLOCK:
and during zone violations which causes a transition to the MACHINE STOP state. A Start signal
transition must occur before returning to MACHINE RUN following any transition to MACHINE
STOP.
