For this, a 5 kΩ 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.
This allows setpoint values of up to 50 % each to be preset on 2 power con-
trollers 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 %).
If more than 2 power controllers are required in a plant, they must be divided
into 2 groups.
The "Dual energy management" parameter (Device1 and Device2) has to be
selected in each group.
- Both devices must be connected to the same phase
- The control electronics and the load circuit must have the same phase
- Synchronize both devices by switching them on simultaneously
- Burst-firing operation must be configured
- The cycle time must be set to 500 ms (fixed)
- In each group, one TYA201 power controller must be configured as De-
vice1 and the other TYA201 power controller as Device2.
