Rate Dependent Processing; Rate Control - Baer DLX User Manual

3.7

Rate dependent processing

The DLX can process up to 4 energy and maximum demand rates. Please
note that there is a differentiation between „number of rates" (programma-
ble) and "rate control" (settable).
With "rate control" one can select the method of switching between different
rates. There are two alternatives:
1. The rate is determined by control inputs TR1, TR2, TR3 and TR4 (external

rate control).

2. The rate is determined by the internal rate calendar.
The "number of rates" determines how many different rates the unit will dif-
ferentiate and use. If the unit is programmed to use less than 4 rates, then
the limit used is the highest programmed rate. If, for example the number of
energy rates is programmed to 2, then the energy registration will only al-
low rates 1 and 2, even if the rate calendar stipulates rate 4. In this case
rate 2 would be used instead of rate 4.
Example: Number of rates:
AT1 (theoretical)
AT2 (theoretical)
AT3 (theoretical)
AT4 (theoretical)
3.7.1 Rate control
The currently active rate can be determined either via the rate control in-
puts (e.g. radio clock, or ripple control receiver) or via the internal rate cal-
endar. Both are queried all the time:
•
AT: Changes have an immediate effect on the energy rate.
•
MT: The current maximum demand rate is always determined 5 seconds
before the end of the current registration period and is then valid for this
registration period (only one demand rate is possible per registration pe-
riod.
