Additional components that are not illustrated:
1 Mounting device incl. signal wire,
4 mounting brackets with M8 screws, nuts and washers for
mounting of the c-profiles at the rail,
4 screws M6, nuts and washers for mounting of the receiver and
the swing protection at the c-profiles,
2 screws M4, wingnuts and washers for mounting of the
transmitter at the link,
1 correction sensor (only USP 100),
5 actuating magnets (only USP 100).
Functioning of the system
The absolute elevator positioning system USP is a non-contact
system to determine the position of the elevator cabin over a
travelling range of 30 meters (USP 30) or 130 meters (USP 100)
respectively.
Using a trigger pulse sent out from the receiver, the transmitter
triggers an ultrasound pulse within the signal wire. This pulse is
propagated within the wire in the direction of both the shaft pit
and the shaft head.
The incoming pulse is converted by the receivers – located in
either the shaft pit or the shaft head – into an electronic positio-
ning value. This positioning value can be recalled by the control
unit at any time in the form of serial data. The evaluated mecha-
nical pulse is then neutralized by the two dampers.
The additional components installed with the USP 100 are the
actuators and correction sensor that provide additional values
for exact position determination over longer travelling distances
and therefore equalize variances in shaft heights.
The USP can determine the exact position of the elevator cabin
at any time through this principle.
Appropriate use
The elevator positioning system USP is to be used exclusively
for position determination within vertical conveying and elevator
technology. Any other use shall be regarded as inappropriate.
The manufactuer shall have no liability whatsoever in the event
of inappropriate use. Appropriate use is defined as complying
with all the instructions given in these operating instructions.
