1 Introduction

1.1 General Overview

The SV-3000 is designed to work on tensile and compression. Designed for measuring the load limits on beams based on the metallic structure deformations (steel beams) or in elevators. Where variations of the load due to the addition or the subtraction of weight in the cabin, transmits deformation of the beam structure measured by the sensor.

The SV-3000 is easy to install on a clean part of the load-beam structure. This load weighing system could be used in lift installations, making it easy to install on the elevator.

This sensor has a cable with USB output or depending on the load weighing control. It is possible to improve the quality of the measurement by adding more than one sensor to the installation.

For installations requiring more than one sensor, multiple sensors can be connected to an (1) INTERFACE device. INTERFACE device can accept USB output sensors and provide either USB output or 5 wire connection to the load weighing control. The correct INTERFACE device should be ordered based upon the load weighing control connection requirements. (1) INTERFACE

2.2 Installation depending on the type of beam

In UPN profile beams such as IPNs have an inclination that must be corrected by adding the wedge washer to the installation so that the nut support is perpendicular to the screw.

3.1 Installation scheme for 1:1 suspension

FIGURE 1 shows a typical installation with 1:1 suspension. In this installation the sensors position is important and should be about 50mm on the support beam from where the load can be measured. Do not mount over gussets or braces that may limit deflection.

● Where the sensor is installed must be clean, smooth and without any coatings. Sensor installation ● To improve accuracy you may install and connect

additional sensors to the load weighing control. Order the correct sensors and/or INTERFACE device based upon the load weighing control connnection requirements.

For the placement of the SV-3000, it is important to place it at a point where you can measure the deformation variations in the bearing structure.

In this example we propose an installation on an elevator with pulleys, in FIGURE 4 we show different examples of standard Sensor installations. installation The typical installation only requires one main sensor. Only in installations where greater accuracy or installations with very stiff beams will you need to add a secondary sensor.

3.3 Step by step installation

Read all the points in the manual before you start the installation.

(1) It is recommended to install the sensor with the elevator located on the ground floor and with an empty cabin, as this is where the measurement point supports less load.

(2) Mark the fixing holes as close as possible to the beam anchor. In the case of mounting it on the main beam take into account the position indicated in FIGURE 1. (At the top of the beam, and about 50 mm

from the support that holds the beam).

(3) Drill the two holes with a 10mm drill bit, and perpendicular to the surface where the sensor will be installed. Ensure that the sensor is as close to the beam anchor as possible.

(4) Once the holes have been made, all the waste must be cleaned and the paint removed from the areas where it will support the sensor (especially if the paint is very thick). Holes must be well-placed, for screws to be easily inserted into holes without adding additional forces to the sensor.

(5) Place the screw on the top of the sensor leaving the head located on it, and the washers on the opposite side. In case of a UPN beam, use the wedge washer so that the nut support is perpendicular to the screw shaft. Once the washers (flat and wedge in the case of UPN) and nut are placed on the opposite side of the sensor, the head is fastened with an allen wrench, so as not to twist the sensor, when the nut is tightened on the opposite side as shown in FIGURE 5 at 35Nm or 25 ftlbs. Make sure the four small feet of the sensor are on the beam surface.

(6) To finish you will need to connect the sensor to the oad weighing control. The sensor may have a USB

cable connection or wire connection depending on the input of the load weighing control. In order to calibrate it, you must refer to the manual of the load weighing control.

To improve accuracy you may install and connect additional sensors to the load weighing control. Order the correct sensors and/or INTERFACE device based upon the load weighing control connection requirements.
