Control circuits conforming with safety categories 2, 3, and 4 can be constructed.
The circuit example below consisting of interlock
switches, force guided relays, and safety contactors are
only a part of a safety-related system in a machine. In
actual machines, risk assessment must be performed
taking various aspects into consideration such as
hazard types, safeguarding measures, and change of
hazard level in operating mode, in order to reduce the
risk of the entire machine to a tolerable level. The safety
category of a machine needs to be evaluated for the
entire safety-related system.

Safety function at occurrence of single faults
•
1. If a short-circuit failure occurs at either of the S1 channels, when
the safety guard is opened, K2 does not turn off but K1 turns off, so
safety function (power interruption to the motor) is maintained. The
system does not restart because the NC contact of K2 remains open
and K3 is not energized even when S2 is turned on.
2. If a short-circuit failure occurs between S1 channels, the potential dif-
ference of K1 and K2 coils become 0V, turning K1 and K2 off. (Fault
detection function between safety input circuits)
3. If NO contact of KM1 is welded, KM2 turns off when the safety guard
is opened, so the safety function (power interruption to the motor)
is maintained. The system does not restart because the NC contact
remains open and K3 is not energized even when S2 is turned on.
4. If the NO contact of K1 is welded, K2 turns off when the safety guard
is opened, so the safety function (power interruption to the motor) is
maintained. The system does not restart because the NC contact of
K1 remains open and K3 is not energized even when S2 is turned on.
5. If NC contact of K3 is welded, K1 and K2 turn off when the safety
guard is opened, so the safety function (power interruption to the
motor) is maintained. Also, the system does not restart because NO
contact of K3 does not shut, therefore K1 and K2 cannot be ener-
gized.
