BPS
The following functions are available to handle electrical heating coils:
• Read energy information.
• Enable electrical heating.
• Limit electrical energy.
The BPS supports these functions as briefly described below. However, the associated
task (TSK 17) must be enabled.
The BATIGYR controllers have information on the consumption of the electrical heating
coil. This helps them calculate the energy consumption of the controlled device since
the last query. The default value for consumption is 3kW. Heating for one minute thus
results in an energy consumption of 0.05 kWh.
The BPS reads the energy consumption calculated for each controller and maps the
value to the associated parameter of the respective @PLTx. The values determined for
all controllers of a group (master and slave) are then totaled in the parameter allocated
to the group point @AIx.
Normally, the default value of the device consumption is saved in parameter
@PLTx.DELF. If the device on controller x has another consumption, the parameter
can be changed accordingly:
– Default consumption (3 kW). @PLTx.DELF = 30
– If total device consumption = 1 kW
Þ
@PLTx.DELF = 10
– If total device consumption = 0.5 kW
Þ
@PLTx.DELF = 5
To enable the controller outputs according to application needs, BATIGYR provides a
parameter with the values AE1 .. AE3.

All controllers of the associated group function according to this default setting, if the
associated parameter is set to the above values in the BPS.
A further parameter allows to limit the output signal for the electrical heating coil in
increments of 10% for all controllers of a group:
– 100 % means: No limitation.
– 10 % means: Output set periodically to 6 sec "On“ and 54 sec "Off“.
The output, of course, is switched on and off only if electrical heating is enabled and if
there is a heating demand.
For further information, refer to the data sheets on the BATIGYR product range.
