Description
Use this parameter to define the contact logic for the alarm output.
Active High -> I > 2.1 mA
Active Low -> I < 1.2 mA
Use this parameter to select which general alarms are output as an alarm current, depending on
the activated Namur classification group.
Alarm Maintenan. – Maintenance required
Alarm OoSpec. – Operation outside of specifications
Alarm Check Fct. – Functional check required
Alarm Failure - Failure
The presence of an alarm can be simulated here in order to output the alarm current.
Description
Use this parameter to specify the lower current range limit for the analog feedback. The current
range corresponds to the configured stroke range.
IMPORTANT (NOTE)
The current range limits can be freely configured between 4 ... 18.5 mA. However,
the current range must not be smaller than 10 % (1.6 mA).
Use this parameter to specify the upper current range limit for the analog feedback.The current
range corresponds to the configured stroke range.
IMPORTANT (NOTE)
The current range limits can be freely configured between 4 ... 20 mA. However,
the current range must not be smaller than 10 % (1.6 mA).
Use this parameter to specify the characteristic curve for the analog feedback.
Direct (rising) = position 0 ... 100 % = signal 4 ... 20 mA
Reverse (falling) = position 0 ... 100 % = signal 20 ... 4 mA
When a general alarm is issued, an alarm current can be sent via the analog position feedback.
These alarm groups are defined in accordance with Namur NE107. A high alarm current ("High" i
>21.5 mA), low alarm current ("Low" I < 3.6 mA), or "Off" can be set for each individual group.
The analog position feedback function is simulated in this parameter group.
Off – End simulation.
Low - Alarm current I < 3.8 mA
High - Alarm current I > 20.5 mA
Input Current - The input current of the positioner is output.
HW Alarm Current - The "AO Alarm Current" set in "Service Mode" is output.
