This document describes the GLT Ω LIFT, an operation and maintenance manual for a lift system. The lift is designed and manufactured by GMV S.p.A., a company specializing in fluid dynamics equipment and components for lifts. This manual, identified by document number 10991793EN, was last updated on October 19, 2022.
Function Description:
The GLT Ω LIFT is a lift system designed for the movement of persons and/or objects within a specified rated load. It aims to provide users with enhanced safety and comfort through various innovative features. The lift can operate with different logics: Universal, Collective Down, and Collective Up and Down.
Important Technical Specifications:
The GLT Ω LIFT incorporates several technical advancements:
- Reduced System Costs: Optimized design to lower overall lift system expenses.
- Compact Dimensions: Reduced dimensions for the well and occupied spaces, including the machinery room (if placed in a cabinet or within the well).
- Faster Assembly: Reduced overall assembly times due to prefabricated components.
- Enhanced Hydraulic Safety: For hydraulic systems, increased safety is provided by a double shut-off valve.
- Smooth Operation: A "soft-stop" system ensures smooth and precise stops at each floor, contributing to greater comfort.
- Adaptable Car Design: An innovative car design allows for future adaptations based on customer needs without requiring major interventions on the lift itself.
- Reliable Electrical System: Features a reliable, prefabricated electrical part that is easy to install and repair.
- Rope System: Utilizes polyurethane-coated ropes (e.g., DRAKA CSR d. 6.5 mm) for enhanced durability and performance.
- Safety Gear Test: Includes specific procedures for safety gear tests, such as the "GMV NEGECOR1 (LCB-EVO)" and "SEA" main controllers, to ensure proper functioning under various load conditions (e.g., 125% of rated capacity).
- TDC (Travel Direction Change) Function: Features a TDC function on the VVVF FRENIC LM2 for managing rope deflection and end-of-life warnings.
- Bypass Devices: The electrical cabinet is equipped with bypass devices for car doors, landing doors, and door closing mechanisms to facilitate fault diagnosis on the safety series. These are identified by "BYPASS" labels (XPC for car doors, XPP for landing doors). Only one bypass device can be active at a time.
- Travel Indicator with Bypass: A luminous and audible indicator under the car activates when the car moves with maintenance push-button panels and a bypass connector is inserted.
- Pit Inspection Panel: A pit inspection push-button panel allows car movement even with the bypass connector inserted. It includes a switch for Normal/Inspection modes and requires an external reset device (SCR key or control panel) to restore normal operation.
Usage Features:
- Intended Use: Designed for moving people and/or objects within the specified rated load. Exceeding the maximum permissible load or number of persons is prohibited.
- User Obligations: Users must wait for doors to fully open, avoid sudden movements, ensure wheelchairs/prams are braked, and keep pets under control.
- User Prohibitions: Prohibits pressing multiple buttons, inserting objects between doors, dropping foreign objects, attempting to open doors during travel, exceeding rated load, unsupervised child use, carrying flammable materials, smoking, and using the lift during external hazards (e.g., earthquake, fire).
- Machinery Room Access: The machinery room must be kept locked. Authorized persons (Inspection Bodies, maintenance personnel) can enter. Custodial personnel or the lift owner can enter only in emergencies, if properly instructed, to perform emergency operations and evacuate passengers. No foreign material should be stored in the machinery room.
- Temperature Range: The machinery room temperature must be between 5°C and 40°C.
- Push-Button Panels: Available in Universal, Collective Down, and Collective Up-Down configurations. Panels include call buttons, alarm buttons, door reopening buttons, car position signals, and overload signals (luminous and audible).
- Reserved Operation ("In the Car"): Activated by a key switch ("1 Extraction - 2 Positions") to "P" position. This cancels calls, disables floor panels, keeps doors open, and allows calls only from the car panel. The key cannot be removed in "P" position.
- Preferential Operation to One Floor: Activated by a "1 Position + Return" key switch on a floor and a "1 Extraction – 2 Positions" key switch in the car. The floor switch returns to "E" (removable key), cancels calls, and brings the car to the activated floor.
- Preferential Operation to All Floors (Hospital Emergency): Activated by a "1 Position + Return" key switch on all floors and a "1 Extraction – 2 Positions" key switch in the car. Similar to one-floor preferential operation, it cancels calls and brings the car to the activated floor.
- Fire Emergency Operation (EN 81-73): Can be manually activated (bi-stable manual device or fire alarm button) or automatically activated (fire detection device). The lift moves to a designated evacuation floor, opens doors (or closes them if required by local regulations), and enters "out of service" mode with a "no access" signal.
- Electrical Emergency Operation (with electricity): Performed on the maintenance push-button panel in the electrical cabinet. Involves turning the "SMMQ" switch to [INSPECTION] and using "SGOQ" and "SMSQ" (UP) or "SGOQ" and "SMDQ" (DOWN) buttons to move the car to a floor.
- Electrical Emergency Operation (without electricity): Involves turning off the main power switch ("QFM"), inserting the "SMEQ" key, waiting for boards to switch on, pressing "SMFQ" until the car reaches the nearest floor, and then evacuating passengers.
Maintenance Features:
- Documentation: Requires a comprehensive maintenance manual, installation project drawings, wiring diagrams, periodical and extra maintenance check results, examination/inspection reports, declaration of conformity, and lift activation requests. All documentation must be kept intact and accessible.
- Safety Precautions: Emphasizes compliance with national workplace safety regulations. Always check that safety devices are activated and functioning.
- Tooling: No special tools are required unless specified by component manufacturers.
- Material Handling: Instructions for careful loading/unloading, verifying received materials, checking for transport damage, proper storage of electrical/electronic components (5°C to 40°C, dry), and periodic checks for prolonged storage.
- Cleaning: Specifies cleaning procedures for car interior, landing doors, door frames, buttons, indicator plates, and sills. Prohibits solvents or abrasives. Recommends damp cloths, specific stainless steel cleaners (isopropyl alcohol), and dry cloths for ceiling lighting and fans (after disconnecting power).
- Rope Cleaning (Coated Ropes): Detailed procedure for cleaning polyurethane-coated ropes (e.g., DRAKA CSR d. 6.5 mm) using isopropyl alcohol, microfiber cloth, and cotton gloves. Emphasizes cleaning one rope at a time with the car stationary, starting from the top floor and moving down in 2-meter steps.
- Discard Criteria for Ropes: Ropes must be replaced based on the number of runs (TDC), years of service life (max 10 years), or visible damage (e.g., 26 broken wires in 30xd length, 13 broken wires in 6xd length, or diameter reduction exceeding 6%).
- Periodical Maintenance and Checks Table: Provides a detailed table outlining recommended maximal frequencies (months/years) for various operation checks across general components, pit, inside well, headroom/car roof, machines room, and hydraulic machines. Checks include visual examination, testing, and measurement.
