Adjusting NORM (standard curve) temperature compensation
Press button twice briefly to activate the
line editing mode.
The split-screen main window shows
which GESTRA bus devices can be
indicated:
■ High-level limiter NRS 1-41
■ Low-level limiter NRS 1-40
■ Level switch NRS 2-40
■ Level controller NRR 2-40
■ Conductivity controller LRR 1-40
Press button four times briefly.
The NORM (standard curve) temperature compen-
sation is suitable for steam boilers operating with
variable pressures, which means that the steam
boilers do not feature fixed working pressures/
temperatures (e. g. low load 10 bar, peak load 15 bar).
The standard curves of 11 feedwater conditioning
agents with different conductivities compensate the
thermal influences of the measurement within the
rated operating range. In our example we have started
from the factory set “TK:LIN” mode.
