Outputting diagnostics messages via the relay
If a relay is defined as a diagnostic relay (
Function
=
Diagnostics
), it works in the
"fail-
safe mode"
.
This means that the relay is always energized ("normally closed", n.c.) in the basic state if
an error is not present. In this way it can also indicate a drop in voltage, for example.
The alarm relay always works in the failsafe mode.
You can output two categories of diagnostic messages via the relay:
• Diagnostic messages from one of the 4 Namur classes
• Diagnostic messages which you have individually assigned to the relay output
A message is individually assigned to the relay output at 2 specific points in the menu:
•

(device-specific messages)
