Lester Controls as a nominated Systems Integrator of Schmersal UK, have been using the USP Shaft Positioning System for the last 5 years.
The ease of integration with Lester Control Systems, the simple installation method and fine tuning all add up to a “user friendly” positioning system. With over 400 successful installations the USP is a proven product backed by Lester Controls & Schmersal full weight of technical know how.
The principal behind the USP is a very simple one. A specially developed wire is suspended from shaft head to pit. A transmitter is fitted on the lift cabin which the wire passes through. A receiver is installed on the lift at a closed location to the motor room.
The car transmitter induces ultrasonic pulse into the wire under the instructions of the receiver via the parallel interface fitted with the Control Panel. These pulses are then interpreted by the receiver and converted into the distance between the transmitter & receiver. The Parallel Interface gives an analogue shaft profile that Lester Controls interprets 24vDC outputs.
A full installation fixing kit and instructions are supplied, as well as a Lester Controls specific “Dummies Guide” set up and adjustment procedure.
As a “stand alone” shaft position system the USP could prove an effective replacement for tape heads, Inductors & Vanes etc. on most control systems.
An installation presentation can be viewed on the Schmersal website @ www.schmersal.de.
Future development will see the Parallel Interface become redundant and the USP interface via Serial Coms directly to the Almega control Processor using can open Protocol.
