Verify Operation
Test the safety function for proper operation after initial installation of the
safety option module. Retest the safety function at the intervals determined by
the safety analysis described on page 15
.
Verify that both safety channels are functioning according to Tab le 6

IMPORTANT If an external fault is present on the wiring or circuitry controlling the Safety
Enable or Safety Power inputs for a period of time, the safety option module
does not detect this condition. When the external fault condition is removed
the safety option module will allow an enable condition.
To achieve maximum safety rating, both safety inputs SP and SE must be
activated by appropriate dual-channel equipment. The repeated activation
of the safety function by only one input at a time can result in a spurious
detection of a fault.
TIP There is no safe-status output provided on the safety option module.
