ADJUSTING THE COUNTERWEIGHTS
The weight of the counterweights must be increased to
ensure smooth operation. If there is insufficient space to
add to the existing counterweights, remove them and
replace them with blocks of a higher specific weight. To
adjust the weights, release the operator and move the
door to half-open position (45°). The door should remain in
balance.

1 - Open command (N.O.): any device (button,
photocell, detector, etc.) which can give an
opening and/or closure pulse to the door by closing
a contact.
To install more than one opening activating device
connect the N.O. contacts in parallel.
2 - Safety devices
Any device (photocells, sensitive edges, magnetic
loops) with an N.C. contact that activates when
there is an obstacle present in the area protected
by the safety devices and stops the movement of
the door.
To install more than one safety device connect the
N.C. contacts in series.
N.B.: If safety devices are not connected, jumper
terminals 2 and 4.
