Assignment Variant 1 (SPM-16A)
NOTICE
Assignment Variant 1 guarantees performance level "d" according to EN13849-1
for the interlock circuit. Prerequisite is the correct wiring of the interlock circuit us-
ing appropriate safety switches and cables:
For the interlock switches positively opening contacts according to IEC60947-5-1
must be used (e.g. SCHMERSAL AZ 16-02ZVRK). The supply lines must have
individually shielded cores (e.g. HELUKABEL LiY-TPC-Y (4x2x0.5 or 2x2x0.5) P#
21357 or 21355.
The MTTF calculation used for achieving performance level "d" is based on the
following assumptions:
1) Number of operating hours/day = 21 (3 shift operation with 1 hour break)
2) Number of operating days/year = 310 (365 days minus sundays/holidays)
3) Cyle time in seconds = 28,800 (8 hours 3 shift operation with 1 cleaning cycle
per shift)
4) Resulting average number of cycles per year = 813.75
