Technology functions
All technology functions, such as
● Pulse stretching
● Chatter monitoring
● Changeover errors
● Hardware interrupts
are executed only when there is an error-free signal (QI = 1). In other words, there is no
diagnostics information on the channel (see also section Address space (Page 18)).

Explanation of parameters

Diagnostics: Missing supply voltage L+
The diagnostics alarm is enabled for missing or insufficient supply voltage L+.
Tip: To avoid a diagnostics overload, you should only enable "Diagnostics: Missing supply
voltage" for an active channel.

The diagnostics alarm is enabled if there is a short-circuit of the sensor supply to ground.
"Short-circuit to ground" diagnostics is available with the following sensor setting:
● NAMUR sensor
● NAMUR changeover contact
Diagnostics: Wire break
The diagnostics alarm is enabled if the line to the sensor is interrupted.
"Wire break" diagnostics is available with the following sensor setting:
● NAMUR sensor
● Single contact with 10 kΩ
● NAMUR changeover contact
● Changeover contact with 10 kΩ
