With category 1 the circuits are designed in proved and tested technique. The
"Exclusive-Or" logic monitors the safety function automatically. Only if the ac‐
tivation of Kx matches the switching status, the output level of the gates is
"low". If there are deviations, the error (high-level) is indicated by red indica‐
tor lamps.
With category 2 the monitoring is not designed in safe technique. Therefore
safety function and diagnostics have to be tested regularly (e. g. during each
commissioning).
Category 3/4 (EN 954-1)
If the IndraControl VEH 30.2 shall be used in control category 3 or 4, the
IndraControl VEH 30.2 has to be wired with an appropriate monitoring mod‐
ule also recognizing short-circuits and cross-circuits in the line. For this, the
safety relay combinations SCR4-W22-3.5-D (part no. 607.5111.009; Bern‐
stein AG) are recommended.
