Connections To The Electric Power Network - Corghi ERCO 4004 Manual De Uso

CAUTION: During the following steps it is essential that the bearing ropes (6 Fig. 10) are not subject to crushing or to excessive bending that
might impair rope resistance. It is furthermore important to guide the ropes correctly in the respective rope pulleys (Fig. 9), strictly abiding to the following
instructions (see Fig. 9).
6) Lift one of the crossbeams, slide in the numbered ropes (6, Fig. 10) following the diagram in Fig. 9, slide the crossbeam cables into the runway P1
and fix it to the runways, after positioning the moving runway P2 at the desired work width with the screws supplied (8, Fig. 10) without tightening them
completely. Repeat this operation for the other crossbeam.
7) Check that the crossbeams-runways unit is perfectly squared and that the moving runway P2 (4, Fig. 6) can slide freely between the crossbeams,
then tighten the screws (8, Fig. 10).
8) Pull the numbered ropes out of the crossbeams making them pass on the respective rope pulleys (Fig. 13 and Fig.14). Insert the screw, which
was previously removed, into the crossbeam hole placed under each pulley (3, Fig. 12) and fasten it with the nut (23, Fig. 10) to prevent ropes
from coming out.
9) Insert the drilled bars into each end of the crossbeams (9, Fig. 10), which are available in two versions (RH and LH) so that the bar holes (10, Fig. 10)
are in correspondence with the safety wedges (2, Fig. 19) and the threaded fitting (12, Fig. 6) is placed at the top end of the bar and toward the outside
part of the lift. The bars should pass through the nylon guides (1, Fig. 16).
10) Mount the motor with the hydraulic control unit (24, Fig. 10) on the control column (3, Fig. 10), the one featuring the holes, using the screws
supplied (24, Fig. 10).
11) Place the control column (3, Fig. 10) upright at the side where the pipes and cables of P1 runway come out, close to the crossbeam end. Place also
the other columns (15, Fig. 10) upright close to the crossbeam ends.
12) Place each column so that the crossbeam ends pass into the columns and the nylon sliders (16, Fig. 10) at the crossbeam ends lean against the
internal side of the columns. Check that the columns are perfectly perpendicular to the floor.
13) Then fix the drilled bars (9, Fig. 10) to the top of the columns using the supplied screws and washers (17, Fig. 10) leaving a small clearance
as shown in Fig. 18.
14) Fix the 4 numbered ropes (6, Fig. 10) to the top of the respective columns (Fig. 17) using the supplied nuts and washers (18, Fig. 10).
15) Fix the wheel stop brackets (18, Fig. 11) to the runway ends on the control column side, using the screws and nuts supplied.
16) Install the ramps (20, Fig. 11) to the other ends of the runways fixing the connection pins to the runway holes.
17) WARNING: fix the supplied screws and nuts (19, Fig. 11) under the ramps and then proceed with their proper adjustment after completing the instal-
lation: before lifting the vehicle, the screws should touch the floor while the runways are down.
4.4.3 ELECTRICAL AND HYDRAULIC CONNECTIONS
CAUTION: It is crucial that hydraulic system and connections are duly laid out.
1) Fix the fittings supplied on the hydraulic unit (1, Fig. 11) as follows:
• Remove the metal plug (2, Fig. 11) from the unit and fix it with the washer (3, Fig. 11) to the T union (4, Fig. 11).
• Remove the plastic plug from the unit and fix the T union (4, Fig. 11) with the conical union and with the other washer (5, Fig. 11).
• Finally fix the elbow union (6, Fig. 11) to the unit, using the Teflon tape.
2) Connect the supply hydraulic pipe (7, Fig. 11) of P1 runway to the union (4, Fig. 11) of the control unit.
3) Connect the discharge pipe (8 Fig. 11) of P1 runway to the elbow union of the control unit (6, Fig. 11).
4) Connect the cables coming out of the runway to the terminal board on the electrical board cable support (Fig. 21). Fit the cover again (Fig. 22).
3) Connect the cables of the other crossbeam to the numbered terminal board (Fig. 21) inside the cover (Fig. 24) placed on the rear side of runway P1.
4) Connect the connector (15, Fig. 11) to the hydraulic unit solenoid valve.
5) Open the contact box of the hydraulic unit motor and carry out the electrical connections with the cable coming out of the board (16, Fig. 11) according
to the supply voltage required, as given in Fig. 12.

4.4.4 CONNECTIONS TO THE ELECTRIC POWER NETWORK

CAUTION:
• The electrical board shall already be connected to a main switch manufactured and installed in compliance with the National prevailing standards.
• The system delivering power to the lift electrical board shall be in compliance with the National prevailing standards.
• Min. needed power is 5 kW.
• Power circuit wires min. section shall be 4 mm2.
• During this phase, electric motor can be operated just for a few seconds, in order to avoid any damage to the hydraulic pump.
1) Connect the power cable (23, Fig. 11) coming out of the electrical board to mains in compliance with the National prevailing regulations.
2) Power the line, and check that emergency Switch/Disconnector/OFF (17, Fig.1) is set to 1 (ON) (turn it if necessary).
the voltage warning LED (18, Fig. 1) will light.
3) Press and release the "UP" push-button (20, Fig. 1) and check that the motor turns in the direction shown by the arrow on the unit. Should this not be
the case, cut off power from the mains and reverse two phases of the power socket coming out of electrical board (during this phase, the electric motor
can be operated just for a few seconds in order to avoid damaging the hydraulic pump).
