1 Introduction

1.1 Product Description

Device for load control in elevators, with individual inputs for 4 to 8 load cells depending on the model.

This solution provides efficient control and maintenance of the installation, with immediate detection of breakage in any belt core. For this purpose, it is necessary to combine this device with our broken belt connectors.

Thanks to NG technology, the device can be combined with a GD-WiFi dongle to monitor real- time data through Dinacell’s Tools NG application. The device is equipped with an alarm with LED light signal. It integrates an associated relay or CanOpen- Lift CIA 417 depending on the model.

Status of elevator belts 1 LEDs indicating belt Solid green Active belt, no errors status Solid red No electrical continuity, this may indicate a detected break in one of the belt cores, or that the BCD connector is incorrectly connected or installed. Flashing green Electrical continuity has been restored. In some cases, a break in the steel cores may maintain partial electrical contact, allowing the system to detect continuity. This contact may be temporarily interrupted, for example, when the belt passes over a pulley, and then reestablished. The device maintains this status to indicate the detection of a possible break, even if electrical continuity is recorded at the time of verification.

The device has a relay that switches to open when the alarm is triggered. This alarm indicates that electrical contact has been lost, which may be due to: - A break in one of the belt cores, causing continuous or partial loss of electrical contact. - The BCD connector is incorrectly connected to the device or poorly installed on the belt.

3 Step-by-step installation

1 Mount the device The first step involves mounting the device onto a solid surface inside the elevator. It is important to note that the broken belt detection system consists of an SCR device and two types of connectors, one of which includes a cable connection. These connectors are installed at the free ends of the elevator belt. Specifically, the device should be placed close to the cable connectors.

2 Wiring More information about wiring can be found in sections 2.1 and 2.2.

- Install the broken belt connectors at the belt ends as described in the corresponding manual. - Connect the connectors to the device following the order B1, B2 ... B4.

- Then connect the alarm relay to the control panel. Note that the relay contact is normally closed when the system is correct, and it will open if power is lost or a broken belt alarm is detected. - Finally, connect the 24VDC power supply to the device and check that the power LED is on.

3 Programming the number of belts By default, the device has all four belt status LEDs active. If they do not match the number of belts connected to the device, you must configure them using the ±B keys, as indicated in section 2.3. e a d r ol nt bi o n ac C ±±BB RESETA LARM TEST PENDING SerieSCR BB11 BB22 BB33 BB44 &&PP OOUWTEPWUT

5 Reset the alarm and check the belts Reset the device by holding the “RESET” button until the alarm LED turns off.

After resetting, if any LED remains red or flashing green, it may be due to incorrect installation of the broken belt connector. Check the installation following the instructions in the corresponding manual.

6 OPTIONAL - Perform a relay test It is advisable to perform a test on the alarm relay as indicated in section 2.3. When the alarm is active, check that the relay contact has opened, and then reset the alarm.

For proper maintenance of the device, it is advisable to repeat this procedure every three months of operation.

4 Broken belt alarm

The first step is to analyze the cause of the alarm. To determine whether the device is issuing a broken belt alarm, it is necessary to rule out whether the activation was the result of a relay test or if it occurred during the initial installation due to incorrectly placed connectors.

The device detects a broken belt alarm when electrical continuity in the belt is interrupted. This interruption can be either temporary or permanent, depending on the type of break. For example, it is possible for the system to momentarily recover electrical continuity, and for the break to be detected only when the belt passes over a pulley.
