FIXING THE GATE TO THE CHAIN
To properly x the gate to the chain, consider a clearance of 10-15 cm between the xing point and the center lines of the geared
motor and chain stretcher respectively, once the gate has reached the ends of the permitted travel (Pic. 2).

Chain stretcher: existing chain stretchers pre- tted
on the gate can be used, depending on the type of
chain and gate; the picture here represented is
merely indicative.

OVERRIDE FOR MANUAL OPERATION
In order to disconnect the gate from the FIBO 300 LB - FIBO 400 LB geared motors, in situations where power failure is occurring
or during the installation phases, it is required that the override handle be operated. This can be carried out even at a distance
from the motor by means of a metal rope operated by a release lever (Pic. 3).

INSTALLING THE LIMIT SWITCHES
The limit switches are to be installed in such a way that the striking plate (also tted to the chain) can activate the switches
without problems. The electrical connections must comply with the instructions of the Elpro electronic controller (Pic. 4).
