8. TWO-BARRIER CONFIGURATION
8.1 TWO OPPOSING BARRIERS
This configuration makes it possible to install two
opposing barriers with synchronous movement. In
this configuration, one barrier is defined as the Primary
and the other as the Secondary.
The Primary barrier manages all the controls and safety
devices, and the Secondary barrier via BUS 2easy.
Any input signals on the J1 terminal board of the
Secondary board will be ignored.
i
The anticrushing function is active on each barrier and
commands the inversion of both.
