12.1 Application: Controller coupling
Attention: Controller coupling only possible in CONTROL-MODE 15 or 16 !
Application example:
Two separate systems operate at two transformer feed ins; it exists one coupling with
coupling switch between both systems.
a) Coupler opened; both systems operate self-governed;
b) Coupler closed: with the controller coupling both systems are operated symmetrically
in parallel operation (same number of steps in each system)
Coupling of 2 power factor controllers Prophi 15T-III is done via their system interface
with a standard LAN-cable.
The 110...230V~ signal "coupling switch closed“ has to be directed to the external input
of a controller (master). On this controller the programming has to be done as follow:
PROGRAMMING: 2 CONTROL-MODE: 15 or 16 (coupling mode)
On the 2nd controller (slave) the setting is the corresponding control-mode (4 or 5)
No more settings are required !
