1 MAINTEINING OPERATIONS

1.1 PROGRAMMED MAINTENANCE For a correct and safe lift use, it is necessary to make a preventive programmed maintenance, following a fixed plan. To define the periodical maintenance frequency, you should consider more events, particularly :

- Number of travel per year - Travelling and stopping periods - Age and condition of the lift - Site and type of the building in which the lift travel - Passengers and goods demand - Inside and outside working condition (climate, vandalism, etc.)

In the next table, parts are shared in groups and for each group is shown the type of check and its longest frequency recommended. Checks operative instructions are detailed in the maintenance schedules on chapter. Please, note that all checks are applicable only if the part is really installed.

• Replace or restore all the components not correctly working.

IV. Group : Power unit and jack

What to do: (see Fig. 1.3.1) IV.a Valve gaskets seals

- At the end of installation, and during check-ups, verify the gasket seals, in the following way: with the oil at room temperature close the ball valve (B) and open the pressure gauge shut off (6). Check that the pressure gauge reading on pressure gauge should not drop more than 4 bar in 5 minutes.

IV.b Oil level check-up. - With the elevator at the highest floor, check, using dipstick (F) or level

indicator (L), that the oil level is above the minimum level and (the motor should be fully covered in oil).

IV.c Oil Characteristics - Check visually that no change are occurred in the oil conditions. Perform

this check after leaving the system down for a few hours. Once every year it should be better to discharge a little amount of oil from cap (J) and to check if it’s clean. If oil is not clean keep on discharging oil until you see to flow clean oil.

IV.d Motor protection functionality - Disconnect one terminal of the thermistors, and check that the motor

protection working properly. IV.e Filter

- Check static and dynamic (working) pressure at the end of installation. Check regularly that all values of these parameters remain unchanged.

IV.g Pressure gauge shut off (6) - Close the ball valve (B), open the pressure gauge shut off (6) and fully discharge the pressure using

electro-valve (VMD). Close the pressure gauge shut off (6) open the ball valve (B) and check that the level shown on pressure gauge is zero.

IV.h Pressure test (static pressure x2) - This test assures you about the integrity of parts under pressure, including those which can not be

visually checked.

- Observe the car while is travelling and for each floor check (on upward travel and downward travel): A) Acceleration; B) Slow down; C) Stop; D) Quietness; E) Frictionless.

VII.b Revelling - Check the relevelling for each floor: perform the descent manual operation to check that the electrical

circuit and the relevelling contacts work properly. VII.c Pushbuttons and signals

- Check that the pushbuttons and signals in car and at all landing floor are working. VII.d Alarm and intercommunication devices

- Check that the intercommunication and the alarm devices are working properly. VII.e Emergency floor return

- Check that the emergency light, the floor return device and the open doors device (if installed) work properly in case of power failure.

MRL Machine room less

A.1.2 DESCRIPTION The MRL lift peculiarity is to have the hydraulic power unit, the control panel, and, generally, all machinery, in pit, inside the well. This machinery placement oblige the maintainer to follow some particular procedures to provide safe and easy access to the machine room – pit. For this reason on system is installed an additional devices set that consent and at the same time, assure the execution of the maintenance and inspection actions on safety. The additional devices set includes:

- the remote control of the hydraulic power unit and of the control panel - the car stop electrical device - the car stop mechanical device - the remote landing door unlock device

WARNING All the actions should be absolutely made by competent maintenance person, designated, suitably trained, provided with necessary instructions and belonging to the maintenance organization.

A.1.3 COMMANDS OF THE REMOTE PUSH-BUTTON PANEL Main functions of the remote push-button panel: • SPK: microphone and speaker of the two-way means of communication • IN: push-button to enable two-way means of communication • L: Car at floor light signal (led)

- lighted = car in the stop at floor zone - unlighted = car out of the stop at floor zone

• RST: Law 13 reset push-button (only Italy) • KB: plug-in for control panel remote control • UP: ascent push-button • DN: descent push-button • PW: Motive power remote switch • KY: key to enable ascent push-button and system reset

- ON = on work - OFF = not on work

• KY (ON) + UP: lift ascent • KY (ON) + DN: system complete reset
