The UK's largest independent lift control panel manufacturer.

USP Shaft Positioning System

USP 30/100

Since the introduction of the USP shaft positioning system in 2003, Lester Controls, as Schmersal’s official authorised systems integrator, have supplied in excess of 3000 units. This makes them the largest consumer of this system outside its native Germany.

The system works by the transmitter on the lift car inducing an ultrasonic pulse into the wire, which is hung the length of the shaft. A receiver then deciphers the information and, via the “USP” interface located within our control panel, converts the data into analogue signals to suit the processor

The simple installation method, fine tuning and ease of integration
with Lester Controls’ systems all add up to a user friendly positioning
system. With over 1,000 successful installations, the USP is a proven
product backed by Lester Controls & Schmersal’s 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 and
a transmitter is fitted onto the lift cabin which the wire passes through.
A receiver is then installed on the lift at a closed location close to the
motor room.

The car transmitter induces an 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 and receiver. The
Parallel Interface gives an analogue shaft profile that Lester Controls
interprets at 24v DC output.

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 and Vanes
etc. on most control systems.

An installation presentation can be viewed on either our or the
Schmersal website: www.schmersal.de. The USP interface connects
via Serial Coms directly to the ALMEGA Control Processor using
CANopen protocol.

Features

  • The USP is available in two kit forms, namely the USP 30 & USP 100. The USP 30 can be used on installations where the travel does not exceed 30m.
  • All other applications should use the USP 100

Advantages

  • The USP comes complete with an easily
    understandable installation and setup
    manual, which is complemented with a Lester
    Controls’ setup sheet as well
  • Once installation is complete the USP is then
    relatively maintenance free
  • Computer software is available which expands
    the shaft profile into a diagrammatic format
    easily readable on any laptop computer for
    use with a Schmersal P.I
