Parameters and possible parameter values
■
the lower threshold is 3.6 mA,
■
the upper threshold for the failure
detection is 21 mA.
For analog inputs with this programming,
4– 20 mA signals outside these limits are de-
tected as failures (wire break).
Changing the lower and/or upper limit is only
reasonable for control systems whose signals
mightnotliewithintheNAMURspecication.
Lower threshold
Possible setting from 0.0 to 3.6 mA.
Upper threshold
Possible setting from 20.0 to 22.0 mA.
3.6 mA have been set for the lower threshold and 21 mA or the upper threshold in the factory.
This parameter is not applicable for “Split range function”.

8�6�10 Delay of Power Failure Message
If the mains voltage is outside the tolerance of
–30 %/+15 % , a fault signal is set. To prevent
faultsignalsforshort-termvoltageuctuations,
a delay time (duration of the power failure) can
bedenedafterwhichthefaultsignalwillbeis-
sued.Alsorefertogureontheright.
Delay
Possible setting for tolerance time: 0 to 25 s.
Factory setting is 6 s.
