Logic or wiring error
A logic or wiring error does not cause the mode to change; the 3RK3 central unit remains in
safety/test mode. This error category can have the following causes:
• Wiring error
(e.g., feedback circuit switching time violation, cross-circuit between cables):
Display on the central unit Remedy
LED Display
DEVICE Depending on the operat‐
ing state
Resolve the cause and then acknowledge the error with
reset.
SF red
The warning is signaled when the LEDs
of the corresponding inputs start 󹪞ash‐
ing.
• Logic error
(e.g., discrepancy time violation, violation of a signal sequence):
Display on the central unit Remedy
LED Display
DEVICE Depending on the operat‐
ing state
Acknowledgment is not necessary. When the logic is cor‐
rect, the error is automatically canceled.
SF 󹪞ashing red
The warning is signaled when the LEDs
