25. Otherwise, connect them now.
Carry out a bleed cycle after having reinstalled the hydraulic unit.
MULTIPLE CONNECTIONS
If multiple bollards (max 3) are installed, which are controlled by a
single JE275 board, connect the pressure switches in series as indi-
cated in the following diagram.
If multiple bollards (more than 3) are installed, which are controlled
by JE275 boards in a master / slave configuration, connect all the pres-
sure switches in series on the inputs of the master board as indicated
in the following diagram.
