6. FUNCTIONING MODE
6.1. Restart mode
The interruption of a beam due to an opaque object causes the
opening of OSSD outputs and the stop of the safety light curtain,
SAFE (BREAK) condition
.
ESPE standard operation can be reset (OSSD safety contact closing
= NORMAL OP. condition,
) in two different ways:
 Automatic Restart, After activation, ESPE resets to standard
operating condition once the object has been removed from the
controlled area.
 Manual Restart, After activation, ESPE resets to standard operating
condition only once the reset function has been enabled and
provided that the object has been removed from the controlled
area. This condition, called interlock, is signalled on the display
(see paragraph 7.2)
WARNING: Carefully assess risk conditions and restart modes.
In applications protecting access to dangerous areas, the automatic
restart mode is potentially unsafe if it allows the operator to pass
completely beyond the sensitive area. In this case, the manual restart
or, for example, the manual restart of the SE-SR2 relay (paragraph
4.1 "Notes on connections") is necessary.
