3.7.3 Rate control inputs
The rate control inputs TR1 to TR4 determine (if desired and if present in
the customer specific hardware configuration) the currently active energy
rate and maximum demand rate. The usage of inputs and the correlation of
input states to rates can be programmed freely (settable).
The factory default settings use TR1 to switch between two energy and
demand rates.

The state of deactivated control inputs (in our example: TR2, TR3 and
TR4) has no influence on the rate control (no matter whether the state
is 0 = open or 1 = closed).
If other combinations are desired, they can be programmed (see user man-
ual of DLXPARA).
Example: rate control for 4 energy rates and 2 demand rates, controlled by TR1, TR2
and TR3.
