Glossary

Automatic Start

Upon completion of power-up, the ESPE will enter the MACHINE RUN state

as soon as the detection zone is clear of opaque objects of the specified

size.

Detection Zone

The IR light sensing area of the ESPE. When a specified test piece enters

this area then the ESPE must detect its presence and set its safety outputs

to the OFF-state.

Electro-Sensitive

Protective Equipment

(ESPE)

An assembly of devices and/or components working 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

When the ESPE detects a fault, it transitions to this state. The OSSD will be

held to the OFF-state and the ESPE will not attempt to leave this state with-

out 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

When the ESPE is in this state, the two OSSD are both active. In this state

the Green MACHINE RUN LED is on, the red MACHINE STOP LED is off

and the Yellow INTERLOCK LED is off.

MACHINE STOP

When the ESPE is in this state, the two OSSD are both inactive. In this state

the Green MACHINE RUN LED is off, the Red MACHINE STOP LED is on.

OFF-STATE

The state in which the output circuit is interrupted and does not permit the

flow of current.

ON-STATE

The state in which the output circuit is completed and permits the flow of cur-

rent.

Output Signal

Switching Device (OSSD)

The safety output of the ESPE that is used to enable and disable the

guarded machine.

Response Time

The maximum amount of time required for the ESPE to set its OSSD outputs

to the OFF-state once the detection zone is blocked by an opaque object of

the specified size.

Start INTERLOCK

Upon completion of power-up, the ESPE must go to the "INTERLOCK" state.

A 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

The ESPE will go into the INTERLOCK state upon completion of power-up

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.
