Operating Instructions, 12/2014, A5E02344528-09
6.2.3.2 "2.2 Output"
"2.2.1 Damping"
Conditions: None
Factory setting: 2 s
Setting range: 0.0 ... 100.0 s, in steps of 0.1 s
Purpose: Setting the electrical damping
Description: This parameter sets electrical damping in seconds.
This affects the Primary Variable (PV) "2.1.1 PV Select" (Page 83) and
hence the "4.3 Analog Output" (Page 139) parameter.
"2.2.2 Current Limits"
The following parameters allow you to set the limits of the saturation range.
"2.2.2.1 Lower Limit"
Factory setting: 3,8 mA
Adjustment range:
•
≥ 3.55 mA
•
≤ 23 mA
Purpose: Setting of the lower current limit
Description: This parameter allows the lower current limit to be adjusted in the prescribed
limits of the total current operating range.
The specified accuracy of the current output signal only applies within the
current limits 4 to 20 mA.

"2.2.2.2 Upper Limit"
Factory setting: 20,5 mA
Adjustment range:
• ≥ 3,8 mA
•
≤ 23 mA
Purpose: Setting of the upper current limit
Description: This parameter allows the upper current limit to be adjusted in the prescribd
limits of the total current operating range.
The specified accuracy of the current output signal only applies within the
current limits 4 to 20 mA.
