Message Output "System OK"

22/162 ekr 500 digital Unit Touch – Installation and Commissioning Manual
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
Supply voltage not present
Limit switch active
Motor overcurrent
Motor control timeout
Supply voltage outside the permissible range
External motor output stage fault
A description of the individual faults can be found in the operating
manual of the ekr 500 digital Unit Touch controller (document
number MD.492).
