Messages
The messages are impermissible deviations from the normal state. They can be
output either via the RS-485 interface or via two floating message contacts.
The controller displays the messages with a help text.
Message causes can be eliminated by the operator or a specialist workshop. If
this is not possible, contact the Reflex Customer Service.
Note!
When the cause for the message is eliminated, you must acknowledge
the fault with "OK" at the controller's operator panel.
