15.2 Magnetic switch monitoring/manual, monitored
start
– Two-channel, non-equivalent magnetic switch monitor-
ing

tored start
S1 = Mechanical safety door switch
S2 = Manual reset device
S3 = Solenoid switch
K1/K2 = Contactors
Cross-circuits in the cable installation can be
excluded if the safety relay and external con-
tactors K1 and K2 are located in the same
electrical installation space.
