properly aligned with the distance D = 3350 mm between them (fig 3)3. If necessary place shims underneath the bases of the pillars so that they are firmly

supported and the pillars are perfectly vertical4. Use a drill bit f24 to drill holes at least 200 mm deep, and clean the holes thoroughly5. Fit the ten M16 Fischer FH 24/25 H or equivalent anchor bolts in the holes and then

tighten with a torque wrench set at 120 Nm first place the thick washer provided withthe fixing kit between the anchor bolt washer and the pillar base plate

After a few cycles with full load, check that the anchor bolts are still firmly tightened.This check must be repeated every 3 months.

WARNING

The manufacturer declines liability for any damages resulting from failure to follow theabove instructions, which may invalidate the warranty.


Electrical connectionsThe machine’s electrical system consists of a control panel halfway up the right-handpillar, and wiring consisting of large-gauge wires for the power supply and the two motorsand small-gauge wires for the control devices (limit switches and Hall effect sensors).The two pillars must be connected together at the top (standard solution) or at the bottom.

WARNING

Any work on the electrical system, including minor operations, must be carried out bya qualified technician.

The electrical connections consist of the following stages:- connection of the two pillars;- connection to the electricity mains;

Connection of the two pillarsOn shipment, the cables of the motor and the sensors installed on the left-hand pillar aredisconnected from their respective devices, removed from the pillar and wound into coils.During shipment, the two pillars are packed independently.

Connection with cables passing above the pillarsTo restore the connection between the two pillars, proceed as follows:1. Place the right-hand pillar in its definitive position and fix it to the floor;2. Place the left-hand pillar in its definitive position and fix it to the floor;3. Fit the metal raceway pipes (optional) to form the arch connecting the two pillars. The

room where the lift is installed must be at least 420 cm high (see fig.4). The cables mustbe inserted in the raceway pipes during construction of the connecting arch.

4. Once the connecting arch between the two pillars is complete, insert the left-handpillar Hall effect sensor cable through the slot provided in the motor mounting plateand connect it to the Hall effect sensor circuit board;

5. Pass the left-hand motor (M1) cable and the left-hand motor overload cutout (S1) cablethrough the two cable glands on the lid of the motor terminal box and connect themto their respective terminals. The connection order of the left-hand motor cable wiresis: BLUE = W2, BROWN = U2, BLACK = V2. The connection order of the overload cutoutcable wires is not important.

6. Connect the cable of the left-hand up limit switch (SQ4) to contacts 21 and 22 of limitswitch SQ4. This cable and its limit switch may or may not be present, depending on the lift version.

7. Insert the cable of the left-hand down limit switch (SQ2) into the hole in the top of theleft-hand pillar and bring it out of the bottom hole just above the limit switch itself.Then connect the cable wires to contacts 21 and 22 of the limit switch itself. Theconnection order is not important.


GB

Connection with cables passing across the floor1. Place the right-hand pillar in its definitive position and fix it to the floor, taking care not

to damage the cables leading out of the base;2. Place the left-hand pillar in its definitive position, keeping it just above the floor with

the aid of a crane;3. Unwind the coils of cables at the base of the right-hand pillar, passing them along the

channel already made in the floor between the two pillars;4. Insert the cable of the Hall effect position sensor (screened cable), the left-hand motor

(M1) cable, the cable of the left-hand motor overload cutout (S1) and the cable of theleft-hand up limit switch (SQ4) and bring them up from the base of the left-hand pillar,bringing them out of the hole provided on the top of the pillar itself. Fix the cablestemporarily with adhesive tape. NOTE: The cable of the left-hand up limit switch (SQ4) mayor may not be present, depending on the lift version.

5. Insert the cable of the left-hand down limit switch (SQ2) and bring it up from the baseof the left-hand column, bringing it out of the bottom hole in the pillar. Fix the cabletemporarily with adhesive tape.

7. Once all the cables have been inserted, lower the left-hand pillar and fix it definitivelyto the floor.

8. Make the definitive connection of the cables to the relative devices. The connectionorder of the left-hand motor cable wires is: BLUE = W2, BROWN = U2, BLACK = V2. Theconnection order of the overload cutout cable wires is not important. Connect the wiresof the cables of limit switches SQ2 and SQ4 to contacts 21 and 22: the wire connectionorder is not important.

During all these operations, it may be of assistance to use a cable laying tool of the kindnormally used by electricians to aid insertion of the various cables.

Connecting to the electricity mainsThe machine must be connected to the mains electricity supply by the customer.To connect to the electricity supply, use a 3 core + earth cable with cross section of 2.5 mm2.The cable must be completed with a mains plug of the type in use in the country wherethe lift is installed.

The lift is fitted for the mains connection cable to arrive from above, but it can also bereceived from below. However, in this case a cavity has to be dug underneath the base ofthe right-hand column to allow the power supply cable to pass.If the power supply cable enters from above, it must be inserted into the hole providedon the arch connecting the two pillars. After it leaves the tubular element which forms thearch, it must be inserted in the hole in the top of the right-hand pillar and brought into theelectrical panel. The cable can be brought into the pillar through the piece of compressedair hose inserted for this purpose when the lift is produced.

If the power supply cable arrives from below, use a cable laying tool of the kind normallyused by electricians to aid insertion of the cable through the inside of the pillar.

Once the cable has been positioned, peel it as appropriate, strip the sheathing off theends of the wires and fit them with insulating bushings and the R, S, T and PE wire markersprovided.Remember that the PE (earth) wire marker is specifically required by the EN 60204standard on electrical equipment, and it is therefore absolutely essential to fit it.


Refer to fig. 5 for details on how to prepare the end of the power supply cable.

The wires must be connected as shown in the electrical system diagram, i.e.:- wires R, S and T to the terminals of the three-pole fuse holder FU1, ensuring that the

markings correspond (wire R to terminal R1 etc.).- The PE (earth) wire to the brass earth bar provided.

The machine normally runs on a 400 Volt 50 Hz (Star) supply or 230 Volt 50 Hz (Delta),depending on the customer’s request. The actual power supply voltage is stated on therating plate.The electrical system and connections are factory configured as a function of the supplyvoltage/frequency.For special versions please contact CORGHI S.p.A.

WARNING

Do not change the factory settings of the electrical connections and do not supply themachine with a voltage and/or frequency that is different from that specified on therating plate.

Before supplying power to the machine, make the following checks:- Check that the power supply voltage and frequency correspond to the values stated on

the rating plate;- Check the condition of the conductors and ensure that the earth conductor is present.- Ensure that there is an overcurrent protection breaker installed upstream of the

machine, with a differential safety breaker.- Connect the appliance’s cable to the mains socket, wiring the three phases R,S,T and the

earth conductor with all due care, and in compliance with the regulations in force.

WARNING


Checking the operationWhen the up-down selector switch is in the central (rest) position, the control electroniccircuit board is not receiving power. When the selector switch is moved to start anyoperation, the circuit board receives power.The indicator devices (warning lights and internal buzzer) must behave as follows:- The three green “power on” lights (+12V, +12VA, +24V) must remain on for as long as the

selector switch is activated. If one or more of these lights fails to illuminate, there is ananomaly inside the electronic circuit board or the transformer.

- The two red overload cutout lights (THERML and THERMR) must always be off. If one orboth of these lights are on, the motors have overheated or there is a malfunction of theelectrical system.

- The red alarm light must come on for a short time (visual diagnostic function) when anyoperation begins. If the light remains on once the operation is in progress, an alarm ispresent.


GB

- The buzzer must sound for a short time (acoustic diagnostic function) when any operationbegins. If the buzzer sounds once the operation is in progress, this provides serviceinformation or indicates an alarm (if the alarm light is also on).

On shipment, the carriages of the two pillars are placed at the same height above theground (about 500 mm) and the heights of both of them are saved on the control electroniccircuit board.Then raise and then lower the lift using the selector switch on the control panel. Thecarriages must ascend or descend simultaneously. If both the carriages run in the oppositedirection to that set using the selector switch, swap two wires inside the power supplyplug.

If the two carriages move in opposite directions to each other, check that the wires havebeen connected correctly on the terminal box of the left-hand motor (M1) (BLUE = W2,BROWN = U2, BLACK = V2). Check again that the movement obtained corresponds to thedirection set using the selector switch.Check that the top limit switches are working properly by raising the lift and operatingthem by hand: the upward movement must stop immediately. During the downwardmovement, the up limit switches must not interrupt travel of the lift.

Note: the left-hand pillar up limit switch (SQ4) is only installed on some versions of thelift.

Check that the bottom limit switches are working properly by lowering the lift andoperating them by hand: the downward movement must stop immediately only on thepillar on which the limit switch is tripped. Repeat the check on the other limit switch.During the upward movement, the down limit switches must not interrupt travel of the lift.

WARNING

In case of anomalies or malfunctions, refer to the table in the Troubleshooting sectionand/or the technical manual.

Lubrication- Fill the container provided with VANGUARD EP 68 oil or an equivalent- Wet the felt with plenty of oil- Check that the felt is correctly positioned: it must be touching the lifting screw


SAFETY DEVICE SPECIFICATIONSThe lift is equipped with safety devices aimed at ensuring maximum protection of the userin the event of a malfunction.The following safety devices are fitted:- Carriage anti-misalignment device: the control electronic circuit board uses two Hall

effect sensors to monitor the position of the carriages in relation to the supportingsurface, and thus to correct any carriage misalignment. If for any reason the carriagemisalignment exceeds the threshold of 50 mm, movement of the lift is cut out immedi-ately and a guided emergency procedure is enabled, allowing the lift to be returned tothe ground, and the carriages realigned.

- Anti-crushing device. crushing of feet is prevented by special foot guards fitted both onthe arms and on the base of the pillar, which prevent the feet from approaching dangerzones.

- Faulty load-bearing nut screw safety device: each lift pillar is fitted with a cast iron safetynut screw; during normal operation, there is no load on the safety nut screw. If the threadof the load-bearing nut screw becomes worn, the safety nut screw guarantees support forthe carriage and its load; moreover, a mechanical device allows the carriage to belowered only but not lifted again.

- Motor overload cutout: if the motor overheats, this device is tripped, stopping it fromoperating until it has cooled down. Each motor has its own overload cutout.

- “Hold to run” controls: when the up/down selector switch is released the lift halts upwardor downward movements at once.

WARNING

All the safety devices must not under any circumstances be tampered with, bypassed,or removed to avoid compromising operating safety. The manufacturer declines allliability for failure to observe this rule.


GB

CONTROL AND MONITORING DEVICESMaster switch/Up-down selector switch (fig.6)

When the switch (1) is turned clockwise (to 1) the lift starts to ascend; when the switch (1)is turned anti-clockwise (to 2) the lift starts to descend.The switch is of hold-to-run type, so when it is released it returns to the central position(0), stopping the movement in progress immediately.This switch also acts as a master on-off switch.

Front panel (fig.6)The front panel has 6 LEDs (2) which indicate the lift’s status. Three LEDs are green andindicate that a number of power supply voltages are reaching the control electronic circuitboard.The other three LEDs are red and come on to indicate that alarms are present.

The meaning of each LED is stated in the table below:

LEDS Colour Description

THERM L RED Normally off. Illuminates to indicate that the left-handmotor overload cutout has been tripped, so Up andDown functions are disabled. Also see the ALARMSsection, MOTOR OVERLOAD CUTOUT TRIPPING.

THERM R RED Normally off. Illuminates to indicate that the right-handmotor overload cutout has been tripped, so Up andDown functions are disabled. Also see the ALARMSsection, MOTOR OVERLOAD CUTOUT TRIPPING.

ALARM RED Normally off. When on, it indicates that an alarm ispresent. The alarm present can be identified on thebasis of this LED’s illumination mode. See the ALARMSTATUS AND INDICATIONS table in point “ALARM STA-TUS AND INDICATIONS”.

+12VA GREEN Indicates that the +12V power supply, used inside thecontrol electronic circuit board, is present. Should al-ways be illuminated when the selector switch is beingoperated.

+12V GREEN Indicates that the +12V power supply, used by the Halleffect sensors, is present. Should always be illuminatedwhen the selector switch is being operated.

+24V GREEN Indicates that the +24V power supply, used inside thecontrol electronic circuit board, is present. Should al-ways be illuminated when the selector switch is beingoperated.


START-UP

WARNING

The machine must be put into service by specially trained personnel, in order to assurethe correct functioning of the lift and all its mechanical and electrical safety systems.

The instructions to be followed are provided in the final section of this manual, for the useof the technicians who carry out the start-up procedure only.No work by unauthorised staff must be permitted.

WARNING

The manufacturer declines liability for any damage resulting from failure to follow theabove instructions, which may invalidate the warranty.

ROUTINE MAINTENANCEIn order to guarantee that the machine remains in good working order and operatescorrectly, it is essential to follow the instructions below:- Once a month, lubricate the nut screws and screws with VANGUARD EP 68 oil or an

equivalent;- Every 3 months check that the lift is fixed firmly to the ground by checking the anchor bolt

tightening torque: 80 Nm for M12 (ERCO 3222 EL) anchor bolts and 120 Nm for M16 (ERCO4022 EL) anchor bolts;

- Check the nut screw wear rod often;- Clean the lift, being careful to remove any foreign objects that may interfere with the

functioning of the mechanical or electrical safety devices.

CleaningWhen cleaning the machine (pillars and plastic guards) use only a soft cloth, dipped in anon-aggressive detergent if necessary. Do not use solvents (petroleum spirit, turpentine,acetone, etc.).

To clean the space between the pillars, simply sweep up the dirt.

WARNING

Never use pressurised water (e.g. high pressure water cleaners) to clean the machine.


GB

USEThe machine must only be operated by authorised personnel. Use of this equipment bypersons not familiar with the procedures described in this manual may constitute ahazard.The operation of the machine is as follows:

Positioning the vehicleWhen positioning the vehicle on the pads, observe the following precautions:

ERCO 3222 ELa) The total vehicle weight must not exceed 3200 kg and must be distributed as

prescribed by the regulations, which specify a maximum load fraction of 2133 kg for oneaxle (corresponding to 2/3) and 1066 kg for the other axle (corresponding to 1/3).

b) When positioning the vehicle on the pads make sure that it is aligned and centred inrelation to the lift’s longitudinal axis.

c) The maximum load of 3200 kg must be distributed over the 4 corners of a rectangle 1000mm wide and 1800 mm long. In case of lower widths and/or longer lengths, the lift’scapacity is reduced. In these circumstances, or in other cases not covered by thismanual, users are advised to contact the manufacturer.

d) Do not use accessories not authorised by the manufacturer to alter the lift padpositions.

ERCO 4022 ELa) The total vehicle weight must not exceed 4000 kg and must be distributed as

prescribed by the regulations, which specify a maximum load fraction of 2666 kg for oneaxle (corresponding to 2/3) and 1333 kg for the other axle (corresponding to 1/3).

b) When positioning the vehicle on the pads make sure that it is aligned and centred inrelation to the lift’s longitudinal axis.

c) The maximum load of 4000 kg must be distributed over the 4 corners of a rectangle 1000mm wide and 1800 mm long. In case of lower widths and/or longer lengths, the lift’scapacity is reduced. In these circumstances, or in other cases not covered by thismanual, users are advised to contact the manufacturer.

d) Do not use accessories not authorised by the manufacturer to alter the lift padpositions.


Lifting the vehicleTurn the up/down selector switch clockwise and release it once the required workingheight is reached.Check carefully that the load remains stable throughout the ascent.If the vehicle becomes unstable or in the event of anomalous operation of the lift,immediately stop the upward movement, wait for the load to stabilise and lower thevehicle to the ground a little at a time. Now reposition the load correctly or put the lift outof operation if the instability is caused by a technical problem.

Lowering the vehicleTurn the up/down selector switch anti-clockwise and release it once the required workingheight is reached.Check carefully that the load remains stable throughout the descent.If the vehicle becomes unstable or in the event of anomalous operation of the lift,immediately stop the downward movement, wait for the load to stabilise and lower thevehicle to the ground a little at a time. Now reposition the load correctly or put the lift outof operation if the instability is caused by a technical problem.

WARNING

The vehicle must only be lifted in the lifting points specified by its manufacturer.

For all service requirements, contact authorised service centres and demand the use oforiginal parts.


GB

EMERGENCY PROCEDURESTwo-pillar lifts offer the following emergency operating procedures:- POWERED EMERGENCY- MANUAL EMERGENCY

These two modes are intended for handling emergency situations which may arise due tomalfunction, incorrect loading, power failure, etc..The purpose is to enable the operator to lower the lift carriages in order to allow removalof the vehicle.Emergency procedures may be executed by the user, but we recommend contacting ourtechnical service department to clear up any uncertainties first.

Emergency procedures are potentially hazardous and must be executed with extremecaution: make sure that all persons are at a safe distance from the lift before proceeding.This chapter uses a number of specific terms to describe the lift’s operating status. Thefollowing table summarises this terminology. Not all the states listed in the table areavailable on all lifts; this depends on the version.

LOCK-OUT Condition in which all operating controls are completelydisabled.

ALARM Condition in which a function is temporarily disabled to warnthe operator of a malfunction or hazard. There are differentalarm conditions, each of which is associated with a differenttype of signal.

POWERED EMERGENCY A condition in which the lift, although in an alarm condition,may be operated in a limited way to enable the user toattempt to reset its operation.

MANUAL EMERGENCY A condition in which the lift is controlled by directly turningthe lift screw by hand with the aid of spanners. This mode istypically used when electrical power is lacking.

Powered emergency procedureThe powered emergency procedure allows the user to attempt to reset the lift’s operationwith the aid of the control circuit board and is enabled automatically when some typesof alarm occur.For information about the types of alarm with which powered emergency mode is enabled,refer to the table provided in the Alarms and indicators section.

To execute the powered emergency procedure, proceed as follows:1. Make sure that all persons are clear of the area around the lift to a safe distance.2. Operate the Up/Down selector switch and hold it in operating position: the buzzer will

sound intermittently to signal a pre-alarm for about one second, and then the lift willstart to move Up or Down

This operation is only permitted a maximum of twice: if the carriages have not reached thefully lowered position (both limit switches operated) by the end of the second attempt,the lift locks out definitively and the only way of bringing the carriages back to the groundand exiting the alarm status is by using the manual emergency procedure.


Note that in powered emergency mode the operator can raise or lower the lift or performcombinations of the two for up to a maximum of two overall operations.However, the lift can only exit an alarm status during a descent, provided the conditionsare met (both limit switches activated).

Manual emergency operationTo lower the lift in the event of a power failure, proceed as follows:1. Switch off the electricity supply using the switch on the mains control panel;.2. Remove the guards from the pulleys on the tops of the pillars;.3. Use two spanners to turn the locking nuts of the two lifting screws simultaneously. The

screws must be turned in synchrony to prevent carriage misalignment.4. Continue to turn the screws by small amounts in synchrony until the carriages are

completely lowered (both limit switches must be activated).5. When the power supply is restored, turn the power supply to the lift back on and lower

the lift to reset the internal position counters (naturally, since the carriages are alreadyon the ground, they will not move).

STORAGEIf the machine is to be out of use for a long period of time, it must be disconnected fromthe electricity supply and any parts which might be damaged by dust must be protected.

SCRAPPINGIf the machine is not to be used again, it is important to make it unusable by removing theelectric motor.It is also necessary to make safe those machine parts that may constitute a hazard.Determine the classification of the equipment in accordance with its disposal class.Dispose of the various components of the lift as metal or electronic refuse at appropriatecollection centres.If classified as special waste, disassemble the machine and sort the components accord-ing to type, disposing of them in accordance with legal requirements.

ALARMS AND INDICATORSSTATUS ALARM WARNING LIGHT BUZZERALARM 0 Rapid intermittent Off

Cause: Data error in eeprom memory. This error is only detected at the start of the up or downmovement (when the selector switch is moved from the rest position).Action: Powered emergency is enabled for a maximum of two attempts. If the lift does notexit the alarm state during these two attempts, normal operation can be restored byreturning the carriages to the fully lowered position (limit switches activated) by hand andthen giving a down command. If the error does not disappear or recurs at the nextoperation, call in the after-sales service.

ALARM 1 Steadily on OffCause: Misalignment of the carriages exceeding the maximum permitted limit.Action: Powered emergency is enabled for a maximum of two attempts. If the lift does notexit the alarm state during these two attempts, normal operation can be restored byreturning the carriages to the fully lowered position (limit switches activated) by hand andthen giving a down command. If the error does not disappear or recurs at the nextoperation, call in the after-sales service.

ALARM 2 Steadily on OffCause: One or more dip switches on the control electronic circuit board are set at ON whenan operation is started.Action: The lift is locked out and powered emergency is not enabled. Release the up-downswitch and set all the dip switches at OFF, then try another operation. If the alarm recurs,call in the after-sales service.

ALARM 3 Slowintermittent OffCause: One or both Hall effect sensor circuit boards are disconnected or it is impossibleto read the magnets due to mechanical deformation and/or because a pulley is not turning.

Action: Powered emergency is enabled for a maximum of two attempts. If the lift does notexit the alarm state during these two attempts, normal operation can be restored byreturning the carriages to the fully lowered position (limit switches activated) by hand andthen giving a down command. If the error does not disappear or recurs at the nextoperation, call in the after-sales service.
