Frequently asked questions about LS Electric (LSIS)
Q.What LS Electric (LSIS) products and parts can Liftech Global Elevators & Escalators supply?
Liftech Global Elevators & Escalators can source, configure and commission LS Electric (LSIS) is7 / sv-iv5 elevator-grade vvvf inverters — including replacement boards, drive units, encoders and firmware — for new installations and modernization across Karachi, Lahore and Islamabad.
Q.Is Liftech Global Elevators & Escalators an authorized distributor of LS Electric (LSIS)?
No. Liftech Global Elevators & Escalators is an independent multi-brand elevator engineering firm. We can work on, supply parts for and modernize LS Electric (LSIS) equipment, but we do not claim to be an authorized distributor of the brand unless explicitly stated in a signed agreement.
Q.Where can I get LS Electric (LSIS) elevator service in Pakistan?
Our head office in Karachi and regional offices in Lahore and Islamabad provide installation, modernization, spare-parts supply and AMC service for LS Electric (LSIS) equipment nationwide. Call +92 300 0000000 or email info@elevatorescalators.com to request a technical consultation.
Q.Does LS Electric (LSIS) equipment comply with EN 81-20/50 and PEC requirements?
LS Electric (LSIS) systems are engineered to major international lift codes. Every commissioning or modernization performed by Liftech Global Elevators & Escalators is verified against EN 81-20 / EN 81-50 safety standards and Pakistan Engineering Council (PEC) regulatory requirements.
Q.How long does a LS Electric (LSIS) modernization project take?
Typical single-car modernization on a LS Electric (LSIS) platform — controller, drive, door operator and safety gear — is completed in 3 to 6 weeks after site survey and part arrival. Multi-car and high-rise programmes are phased to keep buildings operational.
Q.Which elevator controllers from LS Electric (LSIS) are compatible with existing Otis, KONE, Schindler and Mitsubishi installations?
LS Electric (LSIS) integrated elevator controllers (serial CANopen-Lift / DCP-04 architectures) can retrofit into legacy Otis, KONE, Schindler, TKE and Mitsubishi slings. Liftech Global Elevators & Escalators re-wires the traveling cable, re-parameterises the drive and re-certifies the safety chain to EN 81-20/50 before hand-over.
Q.Why specify an LS Electric (LSIS) VVVF traction drive for PM synchronous gearless machines?
LS Electric (LSIS) closed-loop VVVF drives deliver ±0.05 mm/s speed regulation with SinCos / EnDat encoder feedback, essential for smooth stopping accuracy under ±3 mm. This eliminates re-levelling, extends rope life and reduces motor heat losses on gearless PM machines by up to 30%.
Q.How is an LS Electric (LSIS) gearless PM traction machine sized for a given elevator duty?
Liftech engineers select the LS Electric (LSIS) PM machine using rated load, travel, speed, roping ratio (1:1 or 2:1) and starts-per-hour. The chosen machine's static/dynamic torque and duty-cycle (S3 40%–60%) must exceed the calculated demand with a safety margin, per EN 81-20 §5.9.
Q.When is an absolute rotary encoder from LS Electric (LSIS) required instead of an incremental encoder?
Absolute EnDat / SinCos encoders from LS Electric (LSIS) are mandatory on PM synchronous gearless machines because the drive needs rotor-position information from power-up — without homing. They are also required for UCM (Unintended Car Movement) protection under EN 81-20 §5.6.7.
Q.Where are LS Electric (LSIS) door operators and landing components typically installed in modernization projects?
LS Electric (LSIS) VVVF door operators mount on the car-top header and drive both car and landing panels through a coupler. Liftech Global Elevators & Escalators retrofits LS Electric (LSIS) operators onto existing sills in Karachi, Lahore and Islamabad, tuning close/open profiles to EN 81-20 kinetic-energy limits (≤ 10 J).
Q.How do LS Electric (LSIS) cabin fixtures, COP and LOP integrate with a serial car network?
LS Electric (LSIS) COP/LOP panels communicate with the controller over CANopen-Lift or proprietary serial buses, reducing traveling-cable cores from 40+ down to 8. This lowers installation cost, improves diagnostics and enables features such as destination dispatch and remote fault reporting.
Q.Can LS Electric (LSIS) components be supplied with EN 81-20 / EN 81-50 type-examination certificates?
Yes. Liftech Global Elevators & Escalators sources LS Electric (LSIS) safety-critical components (controllers, overspeed governors, safety gears, buffers) with valid EU type-examination certificates and CE declarations, ensuring the modernized car remains compliant during PEC and third-party inspections.
