Outputting diagnostics messages via the relay
You can output two categories of diagnostics messages via the relay:
1.
Diagnostics messages from one of the 4 Namur classes
(--> see the "Adjusting diagnostics information" section for more information on the
Namur classes)
2.
Diagnostics 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:
• Menu/Setup/General settings/Diagnostics/Device behavior
(device-specific messages)
• Menu/Setup/Inputs/../Diagnostics settings/Diag. behavior
(sensor-specific messages)
Before being able to assign a special message to the relay output in "Device behavior", you
must first configure Outputs/relay x:y or /Alarm relay/Function="Diagnostics".

Actuator type
Options
• None
• Unipolar-
• U
Factory setting
None
Here you specify what part of the controller should
power the relay. "U" is the part of the manipula-
ted variable which the controller uses to increase the
process value (e.g. for heating purposes). However,
select "Unipolar-", if you wish to connect an actuator to
the relay that causes the controlled variable to drop (e.g.
for cooling purposes).
Cycle duration
Operating mode="PWM"
(Shortest turn-on time) to
999.0 s
Factory setting
10.0 s
Specify the cycle duration within which the duty cycle
should be varied (only PWM).
The settings for Cycle duration and Shortest turn-on time mutually affect one another. Cycle duration
≥
Shortest
turn-on time applies.
Shortest turn-on time
Operating mode="PWM"
0.3 s to (Cycle duration)
Factory setting
0.3 s
Pulses that are shorter than this limit value are not out-
put in order to conserve the actuator.
Maximum frequency
Operating mode="PFM"
1 to 180 min
-1
Factory setting
60 min
-1
Maximum number of pulses per minute
The controller calculates the pulse duration based on
this setting.
