Smart Control Systems

Replace obsolete logic boards with reliable, open-protocol intelligence.

The lift controller is the central nervous system of any vertical transport asset, orchestrating dispatch logic, motor speed control, door timing, safety interlocking, and emergency communications. Over decades of constant use, original electro-mechanical relay panels or early-generation microprocessors inevitably degrade. Electrical contacts pit and weld, capacitors dry out, printed circuit boards suffer heat fatigue, and replacement parts become completely obsolete on the open market.

Upgrading your lift controller is the most cost-effective and minimally disruptive way to eliminate persistent breakdowns. By replacing only the electronic brain, whilst retaining your existing hoist machinery, counterweight assembly, and shaft guide rails, Sheridan Lifts restores smooth, dependable operation in just a few days. We fit high-specification, non-proprietary control systems that give building managers total independence, effortless fault diagnostics, and complete peace of mind.

CONTROL CAPABILITIES

Tailored control solutions for single lifts and multi-car groups.

Whether managing a single passenger lift in a boutique office or coordinating a high-demand multi-car group in a high-rise residential development, Sheridan Lifts designs controller upgrade packages engineered for your exact traffic profile.

STANDALONE UNITS
Simplex Full Collective Upgrades

Replace outdated automatic push-button (APB) or down-collective relay logic on single lifts with advanced full-collective microprocessors, enabling intelligent two-way call registration, quiet operation, and clear digital fault logs

MULTI-CAR BANKS
Duplex & Triplex Group Dispatch

Synchronise multiple lift cars with interconnected group supervisory controllers. Smart dispatch algorithms dynamically assign the closest car to incoming hall calls, reducing passenger wait times and communal power consumption.

DRIVE INTEGRATION
Controller & VVVF Drive Packages

Combine your microprocessor controller with an integrated Variable Voltage Variable Frequency (VVVF) closed-loop drive for whisper-quiet acceleration, silky-smooth braking, and pinpoint floor-levelling accuracy.

Rapid on-site installation with minimal building disruption.

Unlike major structural overhauls that require weeks of invasive building work, a lift controller upgrade is primarily an electrical and electronic modernisation. Sheridan Lifts’ directly employed engineers can complete a full controller replacement, rewire landing fixtures, install modern shaft position encoders, and commission the system in as little as 3 to 5 days. For multi-lift duplex or triplex banks, we work on one car at a time, ensuring that your building occupants maintain continuous vertical mobility throughout the project.

01 / Specification

Open protocol freedom and digital precision.

Every controller upgrade we specify utilizes non-proprietary, open-protocol hardware from premier UK and European manufacturers (such as Lester Controls and TVC). Onboard digital interfaces provide clear plain-text diagnostics and fault logs, eliminating the need for expensive proprietary handheld diagnostic tools. Paired with modern magnetic tape or optical shaft-positioning sensors, our controllers deliver millimetre floor-levelling accuracy, eradicating trip hazards and ensuring full compliance with the Equality Act and EN 81-80 safety regulations.
02 / Installation

Comprehensive safety and emergency integration.

Modern controller upgrades do not just improve ride comfort; they radically upgrade building safety infrastructure. Each installation seamlessly integrates with modern EN 81-28 emergency two-way voice communication systems, automated battery-backed emergency rescue devices (which bring the lift to the nearest floor and release doors during power cuts), and direct interfaces with building fire alarm panels for compliant evacuation recall under BS 9999.

Typical applications

City centre office
Duplex traction

Two 1000 kg cars in a shared shaft serving eight floors, sequenced as a duplex group to cut lobby waits at peak.

Retirement development
8-person MRL

Machine-room-less lift installed in a four-storey block with no plant space, commissioned before first handover.

Listed offices
Hydraulic

Low-headroom hydraulic lift threaded into a listed stairwell without altering the principal staircase.

Housing block
13-person traction

Full replacement of a 1970s lift in an occupied block, with an agreed twelve-day outage and daily resident notices.
