6.3 Default set point value via potentiometer
For this connect a potentiometer to the voltage input.
It is supplied with DC 10V at terminal 5 of the power controller.
h Set Configuration level
➔ Analog inputs ➔ Voltage measuring range to
0...10V
h Set Configuration level
➔ Set point value config. ➔ Default set point value
➔ Voltage input
Now the power controller power is preset via the external potentiometer.
6.4 Dual energy management
Thus, set point values of up to 50% can be preset for 2 Master/Slave control-
lers without current peaks occurring in the network due to them being
switched on simultaneously.
No current peaks are caused in the network even if the set point values are
asymmetrically distributed, e.g. 30% and 70%.
More than
2 controllers
If more than 2 power controllers are required in a system, they have to be di-
vided into groups of 2. The setting of the "Dual energy management" parame-
ter (device 1 and 2) is carried out in each group.
Prere-
quisites
- Ensure that the two master/slave devices are wired identically as shown in
the following figure.
- The control electronics and the load circuit must have the same phase.
- Synchronize both master/slave devices of one group by switching them on
simultaneously.
- Burst-firing mode must be configured.
- The cycle time must be set to 500ms (fixed).
- Within one group, one Master/slave device must be configured as Device1
and the other Master/slave device as Device2.
