3.5 Message Output “System OK“
The controller is equipped with a message output with potential-
free changeover contact. In a fault-free state, the message
“System OK” is active at the output. If a fault is detected, the relay
switches and the message output signalizes that a fault is present
in the system.
The message output can, e.g. be used to report faults of the web
guiding system to the machine control.
The following faults are output at the message output:
Fault Fault icon
(display screen)
Supply voltage not present
Limit switch active
Motor overcurrent
Motor control timeout
Impermissible supply voltage
External motor output stage fault
A description of the individual faults can be found in the chapters
Special Displays, page 81 and Troubleshooting, page 120.
