Introduction

1.1 Product description

CHDs are composed of a pressure sensor and limiting device. Variations in cabin load due to the entry or exit of loads or passengers are translated to pressure variations that in turn convert the pressure of the hydraulic line into electrical signals measurable by its integrated control system.

The CHD sensor has a robust design, supporting up to 100 bars, and compact, thus without infl uencing the reliability of the pressure system .Providing instead the ease of integrating a load limiter in the elevator or forklifts. The sensor has the standard thread in hydraulic pressure connections and adapters are off ered to other sizes so you will always have the solution for your installation.

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 diff erence 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.

Options submenu Description Parameter to select the type of chain compensation. Within this parameter you can select: Compensation via software No chain compensation

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.

CHD devices integrate a function called AUTO-ZERO, which is activated after selecting a compensation type (cid:31) and set a maximum compensation value (cid:31) . 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.

4.6 CanOpen submenu

NG technology

5.1 What advantages does it have?

CHDs require a gateway like the GD-WiFi model to be able to link wirelessly to a phone, tablet or computer. Or a male USB-A cable to Mini USB-B male to connect to a computer via USB cable.

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.

5.2 Confi guration from mobile, tablet or laptop

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

Components and prerequisites required for the upgrade: - The device to be update must have a Mini USB input for the update (section 1.2). - A USB-a female to Mini USB-a male adapter cable to connect The USB stick to The computer. - A FAT32 USB stick containing only the fi rmware update (fi le. CYP).

The procedure to update a device is the following: (1) Copy the new fi rmware to a USB stick. (2) Turn off or disconnect the power supply from the device. (3) Holding down the M(cid:31) key, reconnect the power supply to the device. The STA LED will start fl ashing and the ERR LED will remain fi xed. (4) You must now connect the USB stick with the new fi rmware to the mini USB port on your device by using an

adapter cable. The ERR LED will fl ash when it detects the USB. (5) Wait for the device to update the new fi rmware. The process can take up to a minute. (6) When the update is complete, the device will reboot automatically.
