3.3.1 Rotary current economic circuit master-slave for resistive loads in star
or delta connection or transformer loads (resistive-inductive)
Prerequisite
To facilitate master-slave operation, the devices must have the same type key
and the same device software version.
The two devices are connected by means of a patch cable (max. length of
30 cm).
The image shows the wiring of a TYA202, which is available ex works as a fully
assembled and configured unit, and behaves exactly like two single TYA201
devices in master-slave operation.
Operating mode
In the standard version, the master-slave economy circuit operates with a U
2
control. The control electronics of the master power controller assume the ac-
tual power control function, and drive the slave power controller in synchroni-
zation. This makes it possible to drive transformer loads. In combination with
the fixed cycle time and the U
2
control, high voltage consistency of the individ-
ual load resistances can be achieved.
A
In the case of power controllers with a load current of 250 A, the fan terminal
X14 must also be supplied with the specified voltage!
The lead protection must be between 2 A and a maximum of 5 A.
