6.3 Default setpoint value via potentiometer
For this, a 5 k
Ω
potentiometer is connected to the voltage input.
It is supplied with DC 10 V at terminal 5 of the power controller.

Now the power controller power is preset via the external potentiometer.
6.4 Dual energy management
This allows setpoint values of up to 50 % each to be preset on 2 master-slave
power controllers without causing current peaks in the network when they are
switched on simultaneously.
No current peaks are caused in the network even if the setpoint values are
asymmetrically distributed (e.g. 30 % and 70 %).
More than
2 power con-
trollers If more than 2 power controllers are required in a system, they must be divided
into groups of 2. The "Dual energy management" parameter (Device1 and
Device2) has to be set in each group.
Pre-
requisites - The 2 master-slave devices must be wired identically as shown in the fol-
lowing image.
- The control electronics and the load circuit must have the same phase
- Synchronize both master-slave devices in a group by switching them on si-
multaneously
- Burst-firing mode must be configured
- The cycle time must be set to 500 ms (fixed)
- In each group, one master-slave device must be configured as Device1
and the other master-slave device as Device2.
