1 Introduction

1.1 Product description

SVDs are a complete load limitation system, consisting of a cell and limiting device. Designed to measure the weight depending on the deformations in metal structures (steel beams) or in lifting systems such as elevators or forklifts, where variations in cabin load by the load inlet or outlet are transmitted to deformation variations of the bearing structure measurable by this system.

The installation of the SVD system can be done easily by placing it in a clear part of the supporting structure. It is possible to improve the quality of the measurement, for this system integrates a USB input that allows adding a second SV-3000 sensor to the installation.

This system allows being placed in already finished installations, providing the facility of integrating a load limiter in the elevator or forklift.

5 2 Safety Nuts M8 Quality 10.0 DIN985

2.5 Installing the sensor

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

The holes in order to fix it must be of 10mm and performed perpendicular to the surface where the sensor will be installed. Making sure that the sensor is as close as possible to the web of the beam. Once the drills have been made, all the debris must be cleaned and the paint removed from the areas where it will support the sensor (especially if the paint is very thick). Drills must be well-placed enough for screws to be easily inserted into the holes without forcing the sensor.

The screw, is inserted on the side of the sensor leaving the head located on it, and the washers on the opposite side. If it is an UPN or IPN beam (paragraph 2.4) use the wedge washer to make the nut support perpendicular to the screw shaft. Once the washers and nuts are placed, you must hold the screw head with an allen wrench, which you should not move so as not to twist the sensor, and tighten the nut tightly on the

opposite side as shown in the figure below.

(par=35Nm, which is 85% of the maximum force to be applied to such a screw).

2.5.1 For installations with 1:1 suspension

This is the typical assembly in installations with 1:1 suspension. It is usually applied in remodeling old facilities. In this installation the position of the sensor is important and must be about 50mm from the support that supports the beam where we are going to measure, as indicated in the graph.

The SVD must not touch any mechanical components in the entire elevator path.

It must be located in an area of the beam or structure bearing without signs of imperfections.

To improve the quality of the measure can be an additional sensor connected to the unit (Chapter 2.1 section 1).

2.5.2 For installations with 2:1 suspension

The scheme on the right would be an example of a typical 2:1 installation where the sensor could be installed anywhere in the structure such as 1:1 and also at the fixed point.

Installing the sensor

In this second example we show an atypical installation where the fixed point is placed on a plate. For the SVD installation, it is important to place the sensor at a point where it can measure deformation variations in the bearing stucture.

4.4 Alarm submenu

In this submenu you can set alarms. If a value is applied to the alarm, when that value is exceeded the alarm will be activated and the state of the relay will change. The status of each relay can be configured individually as open or closed.

The SVDs incorporate alarm LEDs (chapter 2.1 section 5). These LEDs are not linked to the state of the relay but with the alarms.

Options submenu Description Alarm 1: FULL CHARGE.

Parameter to indicate the alarm level. If we apply a value to the alarm, we enable it. When the load value is EXCEEDED, the alarm is activated and the relay will change state. When the alarm is active, the alarm LED indicates.

If the set value is “00000”, this value disables the alarm and the relay will be deactivated.

4.5 Chain compensation submenu

In case you want chain compensation you must connect the HOLD signal to the equipment. In this submenu you can activate or deactivate the possible chain compensations for software or hardware. This

function makes it possible to compensate for the difference in weight between plants produced by the chain. Once the compensation has been set up, after the activation of the HOLD signal with the closing of the doors, the equipment performs the calculation to compensate the weight during the movement of the elevator. In some installations, especially the larger ones, the chain compensation via software does not work with maximum precision due to the friction of the rails between plants and the weight changes during long trips of the elevator. For this type of installation, compensation via hardware is recommended. This compensation requires an auxiliary sensor specially designed for chain compensation.

If a sensor is used for chain compensation, you must NOT include this sensor in the number of sensors section of the calibration (chapter 4.3).

Options submenu Description Parameter to select the type of chain compensation. Within this parameter you can select: Compensation via hardware. This compensation requires an additional sensor to measure the weight of the chain. You will need to place it after the last connected sensor.

Compensation via software No chain compensation Maximum value of chain compensation. (For hardware and software). Select a maximum value to compensate from 0 ... 600

The Operation to set the weight on the lower floor. (Only via hardware). With the elevator on the lower floor select and confirm. The Operation to set the weight on the upper floor. (Only via hardware). With the elevator on the top floor select and confirm.

Actual compensated chain load via hardware. (Read-only) This value is shown in the selected units (chapter 4.3) Sensitivity of the cell to the nominal load of the chain. (Read-only) It is selfcalculated when taking a weight value on the lower and upper floors. It is recommended not to modify this value, in case of doing so the data of chain compensation via hardware will be overwritten and lost. Compensated value of the chain by software estimate. (Read only) This value is shown in the selected units (chapter 4.3)

Time to measure the weight before the HOLD signal triggers. This parameter is measured in tenths of a second and serves to be able to take a stable measure of the weight before closing doors. Delay time to update the weight when the HOLD signal is released. This parameter is marked by tenths of a second and serves to be able to update a stable measure of weight after opening doors.

SVD devices integrate a function called AUTO-ZERO, which is activated after selecting a compensation type ⌧ and set a maximum compensation value ⌧ . This function is designed to automatically eliminate the small possible error that may appear below the marking as the maximum compensation value. The AUTO-ZERO function will be applied when the equipment does not detect any weight change of more than 20kg for a period of time. If the maximum compensation value is set to “00000” it will deactivate the AUTO-ZERO function.

4.9 Cabin display submenu

This parameter is used to define the type of MB booth display you have. In order to properly configure the cabin display, you must take into account that it takes as a reference the levels established in the full load and overload alarms. The LEDs of the silhouette will light up according to the full load level. On the other hand, when the weight on the elevator exceeds the over load limit, the MB will indicate both optically (LED blinking) and audibly (buzzer) that the elevator is overloaded.

Options submenu Description Type of cabin display. MB, cabin display with fixed LED overload. MB, cabin display with progressive LED.

5 NG technology

5.1 What advantages does it have?

Dinacell equipment designed with NG technology is mainly characterized by its possible connectivity with phones, tablets or computers. Allowing through them to read all the parameters in real-time, test the installation and calibrate the unit without having to access its keyboard. In addition, it will allow you to obtain a report in PDF. These reports can be sent via email to keep good control of the facilities. On the other hand, you can record all the information of these reports on the mobile, tablet or computer of all the facilities you want.

SVDs require a dongle such as the GD-WiFi model to be able to link wirelessly to a phone, tablet or computer.

5.2 Configuration from mobile, tablet or laptop

The process of calibrating the equipment with NG technology through a mobile device, tablet or computer accelerates and reduces configuration times.

The steps and procedures when calibrating the equipment are the same (Chapter 7), but much more quickly and intuitively. To be able to enjoy these advantages you will need to connect and download the Dinacell application for your equipment with NG technology.

For more information on the NG connection and its application, refer to the corresponding manual.

5.3 Firmware update

The requirements to upgrade a device are the following:

The device you need to be upgraded must feature NG technology and have a Mini USB input. (section 2.1, point 1). A FAT32 USB stick only containing the firmware update (file. CYP).

A female USB-A to Mini USB-A male adapter cable to connect the USB stick to the device.

The steps you need to take to upgrade the device are as follows: 1) Copy the new firmware on a USB stick.

2) Turn off or disconnect the power from the device. 3) Holding the MM⌧ key pressed reconnect the power to the computer. The AL1 LED will start flashing and the AL2 LED will remain fixed. 4) You must connect the USB stick with the new firmware to the mini USB port on the device using

an adapter cable. The AL2 LED will flash when the USB is detected. 5) Wait for the drive to reboot. The process can take up to a minute. 6) When the upgrade is complete, the computer will boot automatically.
