ELECTRICAL CONNECTIONS
Drive 700 Estru motor pump is equipped with a 230 V - 50 Hz cable
for electric power supply; bring the connections to the Elpro 27
main control panel by an electric cable and connector.
Make sure the two live wires of the electric motor be connected to
the respective terminals in Elpro 27 to get proper open and close
operations.
Should motor fails at starting, add a 12,5 μF capacitor to the live
wires of the power supply.

ADJUSTING THRUST POWER
It is possible to increase or decrease the thrust power, that the jack can exert, by means of two screws, one green and one red,
that control the oil flow to the nearest joint respectively.
Oil pipes are therefore to be connected to the jack in view of the following:
•
red
screw controls pressure in
closing
;
•
green
screw controls pressure in
opening
.

IMPORTANT: the red and green screws control oil pressure to the nearest joint. Therefore
connect the joint which is next to the red screw to get control on closing, while the joint
next to thegreen screw is for opening.

RELEASING FOR MANUAL OPERATIONS
Drive 700 Estru motor pump, double locking version, is designed to allow for jack overriding and in this way it is possible to
open and close the gate by hand. Tighten the knob again to bring back locking feature. On the other way, with the non locking,
reversible version, only the gate lock is to be opened first by its key and then the gate can be moved by hand.
