2 Aim The aim of this manual is to provide instructions for the correct installation, use and maintenance of the GEARLESS type MGV25.2, MGV25.3 and MGV25.5 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. The Gearless motors MGV25 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.

4 MGV25 USER GUIDE MONTANARI GIULIO & C. S.r.l 1 References Standard. 1.1 The following standards are to be considered as references and are not necessarily entirely applicable to this technical instruction. (Table 1) 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 Table 1 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 The entire 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. 2

5 19/02/2013 Ver 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 Operating Conditions. - The gearless machine must be installed in a building or closed hoist-way. - Do not operate the gearless in an explosive atmosphere. - The ambient temperature must be within 0 C and +40 C. 5.2 Handling. The gearless MGV25 can be lifted using the holes already present on the base for the fitting of belts or chains. (Figure N 1) Lifting sample: Figure 1 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. 3

6 MGV25 USER GUIDE MONTANARI GIULIO & C. S.r.l 5.3 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. (Figure N 2) MGV25.2 MGV25.3 MGV25.5 Figure 2 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.

9 19/02/2013 Ver Brake. The gearless is provided with a disc brake that is operated by 2 independent electromechanical devices which are conform to the EN81-1 standard. The gripping calipers are pre-calibrated by the manufacturer and therefore don t require any further adjustment. In attachment, we send the technical documentation of the brake, with the procedure of maintenance, regulation and electrical connection installation. 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. 5.6 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. 5.7 Electric installation. The gearless is directly supplied with cable, with inside three cables for phases (1,2,3), two cables for cooling fan supply (230Vac between F7 and F8), two cables for the Thermistors PTC (T5, T6), one ground cable and one cable for shield (gray cable). (See image below) Figure 10 7

10 MGV25 USER GUIDE MONTANARI GIULIO & C. S.r.l Temporiti s Brake: (For MGV25.2 and MGV25.3 machines) The cables of the brake supply and micro switches must be connected separately. For information about supply the brake, see the label on the brake. For the micro switches, are represent from two contacts, one Normally Open (N.O.) and one Normally Close (N.C.) (See Figure 10). In rested state the gearless brake is closed and there isn t voltage in the coil (Figure 8). In this condition all lift system is motionless. When motor receive a command of moving, the coil is supplied and the brake disk is free changing the status from closed to open and hence the micro switch does the same (Figure 9). Brake disk M1 Coil Coil Micro switch M2 Figure 11 Brake Closed Figure 12 Brake Open For the operating principle of the micro switches M1 and M2 see the table 2. For example: micro switch M1; when brake is close, it s open;but when brake is supplied changing in off status.

11 19/02/2013 Ver.3.1 Intorq s Brake: (For MGV25.5 machines) As Temoriti s brake, the cables of the brake supply and micro switches must be connected separately, but, this brake has to be supplied with Booster device in order to give 207 VDC for 1 second while opening and hold at 104 VDC. See Booster Basic Manual for further information. Figure 14 Brake Closed Figure 15 Brake Open The operating principle of the micro switches is different from Temporiti s brake; in rested state the gearless brake it s closed (Figure 11), and the contact normally open of the micro switch M1 and M2 is open(open circuit). When we will open the brake (Figure 12), all two micro switches changing that status in closed (short circuit). In the Table 3 is explained how to works the contacts of the micro switches M1 and M2.

13 19/02/2013 Ver 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 Emergency manoeuvre. The emergency maneuver 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. 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. 11

14 MGV25 USER GUIDE MONTANARI GIULIO & C. S.r.l 7.2 Component substitution. The instructions for any eventual component substitutions must be asked for each time from the Technical Department, specifying the serial number. 12
