Parameter adjustment TAG…
Outputs
Relay outputs (1 or 2)
Type (B)
–– Type :
(push “OK“ and choose with “+“ and “–“ the
requested relay function off)
• Raising tendency
The relay of relay output 1 de-energizes
when the raising average value out of
“t ges.“ exceeds the previously defined
%-value.
• Falling tendency
same function, however with falling
average value.
–– Deviation in % 2 If the level change exceeds this adjusted %-value,
the tendency determination responds. 0 … 110 %,
example 2 % (modification) per t ges.
–– Deviation per time
–– Scanning time in s 60 Adjustment range 0 … 999 s
Example 60 s corresponds to 1 minute
–– Number of
scannings 4 Adjustment range 0 … 99 steps
Example: t ges = ta • n = 60 • 4 = 240 s = 4 min.,
i.e. after every 4 minutes the average value of the
deviation is generated and the result is compared
with the given deviation in %, here in the example
2 %.
