Introduction
Lift control programming is the process of configuring a platform lift’s electrical and software logic so that all mechanical and safety components work together seamlessly. In accessibility engineering, this means assigning correct input/output (I/O) connections, designing PLC sequences for gate movement and lift travel, and validating the program before the lift ever reaches a site.
This article explains how Sesame Access engineers manage custom lift control systems, using structured software design, machining coordination, and testing procedures that ensure every installation meets safety and performance expectations.
What Is Lift Control Programming?
In simple terms, lift control programming defines how a lift behaves. It determines which buttons activate specific functions, how long motors run, and when gates lock or unlock. For accessibility lifts, this programming must comply with safety standards while accommodating each building’s physical constraints.
Sesame Access specialises in developing tailored PLC-based control systems that synchronise all lift movements, alarms, and sensors. Each configuration is unique, whether for a compact heritage installation or a large modern entrance system.
How Sesame Engineers Optimise Lift Logic
Every Sesame project begins with a detailed review of the lift’s input/output layout to ensure complete alignment between wiring and software. The engineering team uses structured task management to track all program updates, verifying that every command signal matches a real-world function such as gate open/close or offloading valve activation.
During this process, engineers may:
-
Redefine outputs for gate and motor coordination.
-
Program timed delays between motor start and valve engagement.
-
Incorporate safety redundancies through hardwired overrides.
-
Test emergency gate release and fault isolation functions.
This precision-driven approach is what allows lifts such as the Kensington Stairlift and Thames Retracting Stair Lift to deliver reliable operation even in space-restricted or architecturally sensitive environments.
From Design to Machining: Aligning Electrical and Mechanical Systems
Lift software design and mechanical fabrication are closely linked. In the engineering workflow, any mechanical change, such as altering a bearing housing or cylinder mount, is immediately reflected in the control software and BOM documentation.
Drawings and machining instructions are synchronised to ensure that thrust bearings, pistons, and frame assemblies match the programmed travel range and stop positions. This level of integration is critical for complex installations such as the Westminster Equality Act Lift, where tolerances and safety interlocks must align perfectly.
Testing and Onsite Verification
Before commissioning, Sesame engineers bench-test every lift program to validate logic, timing, and fault recovery. Onsite, the team reconfirms sensor positions, pressure switches, and safety circuits to ensure that the physical installation mirrors the digital configuration.
This testing covers:
-
Lift movement sequences (up/down logic).
-
Emergency stop and gate lock interlocks.
-
Pressure and offloading valve timing.
-
Power-failure safety and manual override verification.
By combining software precision with rigorous field testing, Sesame Access guarantees safe, smooth performance across all bespoke lift systems.
Frequently Asked Questions (FAQ)
How is custom lift control programming tested?
Each program is validated offsite using simulation tools, then retested onsite during commissioning to ensure identical performance.
What happens if the PLC software fails?
Core safety features such as emergency stops and gate locks are hardwired, allowing safe manual control until the system is reset.
Can lift logic be changed after installation?
Yes. Sesame engineers can update PLC parameters or I/O assignments as site needs evolve, ensuring the lift remains compliant and efficient.
Why do different lifts need different control programs?
Because every building and installation is unique. Factors like travel height, gate orientation, and available space affect how the control logic is configured.
Which Sesame products use programmable systems?
Most of our modern lifts — including the Mayfair Stairlift and Kensington Stairlift — feature custom PLC programming to adapt precisely to each project’s requirements.
