BCD tap position message
You can use this parameter to set which range of values from the tap posi-
tion table the device is to use for the tap position message via digital outputs
(BCD).
9.4.5 U bandwidth monitoring
The following limit values are monitored via bandwidth monitoring. The set
bandwidth of the voltage regulation is used for this purpose.
▪ Upper bandwidth
▪ Lower bandwidth
You can set the following parameters for each limit value:
▪ Hysteresis limit value: Specification as a percentage relative to the de-
sired voltage value.
▪ Delay time limit value
Behavior
If the measured value is higher than the upper limit or lower than the lower
limit, the device triggers the
Upper bandwidth limit value / Lower bandwidth
limit value
message.
The "Function monitoring" function is used to detect long periods when val-
ues are above or below the bandwidth. Long periods when values are above
or below the bandwidth indicate a problem with the device function because
the device is not able to correct the control deviation.
If the value is above or below the set bandwidth, the
Function monitoring
event is displayed after the set delay time for function monitoring has
elapsed. The event is automatically acknowledged as soon as the measured
value is back within the set bandwidth.
The following parameters are available for setting function monitoring:
▪ Function monitoring
▪ Hysteresis
▪ Delay time
▪ Monitoring U < 30 V
