Current suppression
Place a checkmark in this box to activate the current suppression for the current output
ranges 4 to 20 mA and 20 to 4 mA. When current suppression is activated, the current
output is switched to 0 mA if Channel OK is switched off. With activated current
suppression, the current output can be used to indicate whether the channel is OK or not.
Calibration factor of current
Enter here a factor at the range of 0.9 to 1.1 for the calibration of the current output. This
factor influences the slope of the output curve (see
Current output offset
Enter here a current output offset at the range of ±10 mA. Use this offset for the zero point
calibration (see
Figure 5-38: Diagram current output calibration
Current output response time
To smooth the output current, enter here a time constant at the range of 0 to 25.5
seconds. An input of "0" effects no change in the output current. The time constant causes
a slow change of the current at fast changes of the measuring value.
If a time constant of, for example, 10 seconds is chosen, for example, and if the measuring
value changes suddenly from 100% to 0, it will last approximately 10 seconds till the
current has declined by 63 %. The change curve follows an E-function, this means at a
slower increasing – respectively decreasing amplitude response (see
Note
In case of fault functions and with activated current suppression, the configured function
current output response time has no effect. The current is set to "0" without smoothing.
