Message
This message appears when an attempt has been made to change
the range in such a way that previously input limiting values lie outside
the display and measuring range, or the respective places following
the decimal point would be cut off.
Example:
You have already entered the maximum permitted speed of
600.5 rpm as the upper hysteresis limit and are attempting to change
to the range 0.0 rpm ... 99.99 rpm (limit value outside of display and
measurement range).
Or:
You are attempting to change to the range 0 rpm ... 9999 rpm
(decimal point was removed).
Switching points of the output relay or
(factory preset: 100 or 200)
The output relay switching points are defined by the upper and lower
hysteresis limit. When the upper hysteresis limit O_Gr is exceeded, a
switching operation is triggered and on falling below the lower
hysteresis limit U_Gr, a switch back operation occurs. If a hysteresis
limit is not desired, enter the same value for both parameters. The
output relay then switches both on and off at a defined speed.
