1 Page 1 of 12 INSTALLATION OPERATION AND MAINTENANCE MANUAL GEARLESS MG250 Aim The aim of this manual is to provide instructions for the correct installation, use and maintenance of the GEARLESS type MG250 for use in passenger and freight lifts. Warning: This booklet does not contemplate the instructions for the shutting down of the entire system, but only the instructions relating to the GEARLESS, therefore before starting the installation of the gearless you must follow the instructions in this operation and maintenance manual and take precautions in accordance with the current safety standards.

2 Page 2 of 12 Summary The Gearless motors MG250 and all the components supplied by Montanari Giulio & C, have been tested in order to guarantee their correct operation. The Gearless motor has been tested in both empty and loaded operating conditions, in accordance with the technical specifications for velocity, car capacity load, car weight, presence or not of compensation and the type of roping requested when the order was placed. This ensures the correct operation and a minimum number of set-up operations. All responsibility is declined for any malfunctions due to installation with different characteristics, except in the case of specific approval by Montanari G. & C. 1 References Standard General notes..3 3 Transport. 3 4 Warehouse storage Installation Use.10 7 Maintenance Declaration of Conformity

N Reference Type of standard Description 1 UNI E Maintenance : Terminology 2 UNI EN 81/1 E Safety rules for the construction and installation of passenger and freight lifts 2 General Notes 2.1 The operations described in this manual must be carried out by qualified personnel, equipped with the necessary workshop tools. 2.2 Before all interventions the entire system must be put out of commission to prevent it from being used. 2.3 For all requests for spare parts or for particular instructions it is always necessary to specify the serial number, which can be found stamped next to the electrical connection terminal board. 3 Transport 3.1 All the gearless are packed in cases or crates. In some cases they are mounted upon wooden platforms, in order to be transported correctly on the lorry. The cases and crates are not load bearing and therefore cannot be stacked upon each other. 3.2 The unloading of the material, from the transport vehicle, must be done with equipment that is suitable for both the weight and the dimensions of the load. All the packing is designed for movement by fork lift and low lift platform trucks. 3.3 Upon the receipt of all material, check its condition. In the event of any damage do not proceed with the installation unless authorised otherwise by Montanari Giulio & C.

4 Page 4 of 12 4 Warehouse storage 4.1 Preserve the gearless, even if it is still packed, in a dry place where it is protected from bad weather. 4.2 Once the packing has been removed take the necessary precautions to avoid the settling of any dust. 5 Installation 5.1 Handling The gearless can be lifted using the holes already present on the base for the fitting of belts or chains Lifting example: Care must be taken to ensure that the gearless doesn t get knocked as the brake disc, the brake callipers and the electrical connection terminal board are particularly delicate.

5 Page 5 of Assembly The gearless are ideal for assembly either with or without a machine room. The roping and therefore the load must always be orientated versus the base of the machine as shown in the diagram. In the case of assembly with the machine down, and therefore with the roping and load upward, you must mount it rotated by 180 degrees.

7 Page 7 of Brake The gearless is provided with a disc brake that is operated by 2 independent electromechanical devices which are conform to the EN81 standard. The gripping callipers are pre-calibrated by the manufacturer and therefore don t require any further adjustment. Attention must be paid and if necessary precautions taken to ensure that oil or grease do not come into contact with the brake disc. Grease or oil on the brake disc can jeopardise the braking and put people in serious danger. 5.4 Lubrication The gearless does not contain oil and is supplied with bearings that are lubricated for the life of the equipment, therefore no further lubrication is necessary. 5.5 Electric installation The motor power connector are the clamps L1, L2, L3. The two clamps TR are connected to three PTC probes immersed within the coils of the gearless and they are used to control their temperature, connect them to the inverter or electrical control panel.

10 Page 10 of 12 6 Use 6.1 General notes The gearless are designed and constructed as lifting devices for lifts and hoists and respect the various sector standards. Any other use is to be considered improper. They cannot be used in systems with characteristics that are different to those agreed upon in the order (e.g. carrying capacity, velocity, etc.), Qualified and competent personnel must carry out all tests, inspections or manoeuvres that may be necessary in accordance with the current standards. 6.2 Brake The brake has been designed in conformance with the specific requests of the EN81-1 standard, in particular it is in conformance with paragraph This device is therefore usable as a brake to slow down the car in combination with a suitable speed governor in the case of excessive velocity in the rising direction. The examination certificate is an ABV589 type and is issued by TÜV B.B. 6.3 Emergency manoeuvre The emergency manoeuvre must be made by an independent electrical device, which is capable of opening the brake and moving the gearless at a reduced velocity. It is possible to exploit the characteristics of the synchronous motor as it can slow down the car when the phases are put into short circuit. This system has some load limits and it is therefore necessary to observe several precautions. Montanari Giulio & C. can provide the information necessary to apply the aforementioned solution upon request.

11 Page 11 of 12 7 Maintenance 7.1 Traction/Driving pulley Periodically, at least once a year, check the amount of wear on the cable races on the traction pulley. In the event of the cables slipping or of excessive wear contact Montanari Giulio & C. for the substitution instructions, always indicating the serial number. 7.2 Brake At least once a year check the amount of wear on the brake pads carrying out a braking test as described in the EN81-1 standard, appendix D Component substitution The instructions for any eventual component substitutions must be asked for each time from the Technical Department, specifying the serial number.

12 Page 12 of 12 8 Declaration of Conformity We hereby declare that the gearless models: MG250. DECLARATION OF CONFORMITY (Directive 98/37/CE, Art. 4.2 and Attachment II, par. B.) - are constructed to be incorporated within an existing system or to be assembled with other components during the construction of a new system in accordance with the 98/37/CE directive and successive modifications; - are nevertheless not in conformance with all the single regulations of the aforementioned directive; - are in conformance with the conditions of the following directives 95/16/CE and 89/336/EEC and that - the following Harmonised standards (parts/clauses of) have been applied: EN81.1 ; EN55011 ; EN55014 ; EN ; EN12015/6. We also declare that - the operation of the gearless is not permitted until the existing or new system of which it will be a part, has been tested and declared in conformance with the 95/16/CE Directive or the 98/37/CE Directive as well as the respective National legislation, in other words, until the gearless mentioned in this documentation has become a single assembly together with the system in which it is inserted. The violation of the provisions laid out in these technical instructions will result in the immediate expiration of all the product warranties. Note: With regards to the fulfilment of point 9.7 of the EN reference standard, you are reminded that Montanari provides the protective devices only upon explicit request from the customer.
