Question 1

Why are my CAME DIR 10 photoelectric cells not working and how can I resolve this issue?

Accepted Answer

Several causes may explain the malfunction of your CAME DIR 10 photoelectric cells. Unlike other models, the DIR 10 cells do not require any special intervention for alignment thanks to their integrated optical-electronic circuit, which simplifies troubleshooting. Here are the essential points to check to identify and resolve the issue:

First, check the power supply. The DIR 10 cells operate at 12/24 V AC/DC. Ensure that the correct voltage is reaching the power terminals (marked Rx for the receiver and Tx for the transmitter). Visually inspect the electrical connections at the CAME control panel to determine if there is a cut, disconnection, or a blown fuse. A power supply issue is the most common cause of complete cell malfunction.

Immediately clean the infrared lenses. Even though the cell does not require precise alignment, the lenses must be clear for the infrared beam to function correctly. Check that the lenses are not obstructed by dust, dirt, limescale, or residues. Gently clean the lenses with a soft, dry cloth, without any harsh products. Also, ensure that no physical obstacles (branches, fences, vehicles) block the infrared beam between the transmitter and the receiver.

Inspect the wiring and connections to the control circuit. Examine the cables for cuts, fraying, or signs of mechanical wear. Check that the TX (transmitter) and RX (receiver) connections are properly connected to the correct terminals on the CAME panel (ZA2, ZE3, ZC2, ZH2, or ZR22 depending on your panel model). The DIR 10 cells use a relay contact that must transmit the signal: if this contact is damaged or its range exceeded (1 A max at 24 V), the relay will not close properly.

Check the operating conditions. The DIR 10 cells are guaranteed to operate between -20 °C and +70 °C. If the cells are exposed to extreme temperatures, they may not detect correctly or at all. Also, check that the cell is mounted about 50 cm off the ground, as recommended in the documentation. A positioning that is too high or too low can affect detection.

Test by temporarily disabling the cells. Disconnect the cells from the control circuit and manually restart the gate opening without the cell safety. If the gate operates normally without the cells, the problem lies with the cell itself or its connection. If the problem persists, it is a failure of the control circuit, not the cells. In case of persistent malfunction despite these checks, it is possible that the internal optical-electronic circuit is faulty and the DIR 10 cell needs to be replaced.

Question 2

What is the wiring diagram for CAME DIR 10 cells to ensure their proper functioning?

Accepted Answer

The CAME DIR 10 photoelectric cells consist of a pair of infrared transmitter (TX) and receiver (RX). They do not require any special alignment and should be mounted approximately 50 cm from the ground. The first step is to choose the power supply voltage: 12V or 24V in alternating or direct current depending on your control system. The cells consume 60 mA at 24V a.c. and the relay contact can support a maximum of 1A at 24V.

The wiring depends on your CAME electrical panel. Start by identifying the type of panel (old or new series) to which you are connecting the cells. For the power supply, connect the 12/24V wires (positive and negative) directly to the corresponding terminals of the optical-electronic circuit. The DIR 10 cells have clearly marked terminals on the electronic board for the power supply voltage input.

For signal connections, connect the TX and RX outputs to the CAME panel according to the diagram provided in your manual. The relay contact has three terminals: common (C), normally open contact (C or NC). If you want a reopening during closure, use the appropriate configuration indicated in the wiring diagram provided with the cells. The cable connecting the transmitter and receiver must be at least 2×0.5 mm² in section for simple pairs.

Install the optical-electronic circuit housing (1) on the wall or on the provided mounting base (5), using the supplied fixing screws. Protect the power supply cable by passing it through a suitable conduit to avoid damage. Then mount the infrared screen cover (3) that protects the detector and enhances its robustness against external light interference.

Before commissioning, check that all connections are secure and that the power supply is correct (12V or 24V according to your initial choice). Clean the lenses of the cells with a soft cloth to avoid any obstruction. The cells operate at a range of 10 meters under normal conditions and accept a temperature range of -20°C to +70°C. Restore power and test the operation by interrupting the infrared beam between the transmitter and receiver to verify that the system correctly detects the presence or absence of an obstacle.
