Roger Photocell R90/F4ES - G90/F4ES Installation Manual

1. Introduction to Instructions and Warnings

This manual is intended exclusively for qualified installation personnel. Information contained herein is not of interest to the end user.

This manual refers to the synchronizable photocells R90/F4ES and G90/F4ES and must not be used for different products.

Warnings: Read instructions carefully before installation. Installation must be performed by qualified personnel according to current regulations. Use cables suitable for required currents and voltages, respecting product technical specifications.

To ensure proper functioning, photocells must be aligned correctly without using surface reflections and must not interfere with other photocells (same or different types). Interference may occur between non-synchronized pairs, more than four synchronized pairs, or with other infrared devices. Take all necessary precautions to eliminate this problem. Refer to Figure 2 for reflection and interference issues.

Attention: If the installation distance between TX and RX is less than 2.5 meters, remove the TX and RX lenses; otherwise, proper functioning is not guaranteed. The minimum allowed distance is 80 centimeters.

Attention: Jumper configuration must be changed in the absence of voltage, as they are read only upon power-on, to prevent component damage.

Attention: For AC power supply, connect all TX and RX units with the same polarity.

2. Product Description

The synchronized photocells R90/F4ES and G90/F4ES are infrared presence detectors that identify obstacles in the optical axis between the transmitter (TX) and receiver (RX) photocells. They are suitable for automatic entrances, courtesy services, and passage monitoring.

Synchronization allows connecting up to 4 pairs of photocells without interference. Synchronization is achieved via an additional wire connecting all TX and RX units. Synchronization is generated by a TX photocell (MASTER) and transmitted to its paired RX and all other SLAVE photocell pairs.

In these instructions, the transmitter photocell is referred to as TX photocell, the receiver photocell as RX photocell, and one or more pairs (always composed of an RX and TX photocell) are referred to as photocells.

These photocells are designed for installation on flat, parallel mounting surfaces that allow for proper centering between the TX and RX photocells.

Available Versions:

• R90/F4ES
• G90/F4ES
• G90/F4ES/TRIX/TX and G90/F4ES/TRIX/RX (for installation on TRIX series columns only)

RX Photocell LED (See Figure 1)

• L2: Normally OFF. In "alignment" mode, indicates received signal strength by varying flashing frequency.
• L3: Indicates the status of the OUT contact. Normally ON (closed contact), turns OFF when an obstacle is present between photocells (open contact).

5. Installation

Attention: Before installing, check compatibility and technical specifications of control devices.

Distance > 10m (up to 15m): Cut the bridge on the back of the circuit (Figure 11). Perform precisely to avoid circuit damage.

Distance < 2.5m: Remove TX and RX lenses for guaranteed function. Minimum distance is 80 cm. Remove lenses carefully to avoid damaging photodiodes or other components.

5.1 Mounting

Choose photocell location. Open photocells and extract circuit cards (Figures 6, 7, 8). Attach the bottom shell. For G90/F4ES/TRIX/TX and G90/F4ES/TRIX/RX, fix the upper part (Detail F, Figure 8) to the TRIX column with supplied screws. Position the PCB support (Detail G, Figure 8) on the upper part.

Attention: TX and RX lower shells differ; check embossed writing on the back before fixing.

5.2 Wiring

Warning: Perform wiring with power OFF.

Cables: Prepare 3 wires for TX and up to 5 wires for RX (depending on output connection).

Connect power supply, observing polarity. For AC supply, ensure same polarity for all TX and RX.

Connect all photocells with the synchronization wire (SYNC).

Connect OUT terminals as needed.

Figure 9: Shows typical setup for 4 photocell pairs (e.g., 2 pairs at different heights outside, 2 pairs inside). Input FT1 of control unit connected to FOTO1/FOTO2 outputs (series). FT2 connected to FOTO3/FOTO4 outputs (series).

Figure 10: Shows typical setup for 2 photocell pairs (e.g., 1 pair inside, 1 pair outside). FT1 connected to FOTO1 output. FT2 connected to FOTO2 output.

5.3 Configuration and Alignment

Configure one pair as MASTER (jumper ID1 & ID2, Figure 5). Only one MASTER pair is allowed. Configure other pairs as SLAVE (jumper ID1 & ID2, Figure 5), ensuring different configurations for each SLAVE pair.

Attention: Jumper positions must be changed with power OFF, as configuration is read only upon ignition.

Attention: Setting alignment mode with the SET jumper (Figure 4) disables the OUT output (contact remains open). After alignment, ensure the SET jumper is in the normal operating position (Figure 3).

Alignment procedure is done one pair at a time, observing RX LED L2 flashing for signal strength (faster flash = stronger signal, slower flash = weaker signal).

To align the first pair (MASTER):

• Set the SET jumper (Figure 4) to alignment mode on the MASTER pair.
• Apply power.
• Move the photocell to find the position with the fastest L2 flashing.
• Fix the photocell at the best signal point, maintaining its position.
• Cut power.
• Move the SET jumper to the normal operation position on TX and RX (Figure 3).

Note: In optimal conditions, LED L2 may remain steadily lit.

If no SLAVE photocells exist, the procedure is complete.

If SLAVE photocells are present, temporarily configure the MASTER pair as a SLAVE (jumper ID1 & ID2, Figure 5). This is to avoid interference with subsequent alignments.

To align SLAVE pairs:

• Set the SET jumper (Figure 4) to alignment mode on the first SLAVE pair.
• Apply power.
• Move the photocell to find the position with the fastest L2 flashing.
• Fix the photocell at the best signal point, maintaining its position.
• Cut power.
• Move the SET jumper to the normal operation position on TX and RX (Figure 3).
• Repeat for all other SLAVE pairs.

Once all pairs are aligned: Return the first pair (momentarily configured as SLAVE) back to MASTER configuration. Ensure all SET jumpers on TX and RX are in the normal position (Figure 3).

5.4 Container Closure

To close the photocell containers:

• R90/F4ES: Verify seal (Detail A, Figure 6) is correctly inserted in the upper shell. Position and secure the upper shell with two screws.
• G90/F4ES: Place gasket (O-ring, Detail C, Figure 7) in the upper shell groove. Place gasket (Detail D, Figure 7) and upper shell, secure with two screws. Gently press mask (Detail E, Figure 7) until it clicks.
• G90/F4ES/TRIX/TX and G90/F4ES/TRIX/RX: Place gasket (O-ring, Detail H, Figure 8) in the upper shell groove. Place gasket (Detail I, Figure 8) and upper shell, secure with two screws. Gently press mask (Detail L, Figure 8) until it clicks.

6. Testing

Testing verifies correct photocell operation and checks for interference from nearby infrared devices.

Activate the control device connected to the photocells.

Using a cylindrical object (approx. 50mm diameter), interrupt the infrared beam between the photocells multiple times. Repeat by positioning near the TX photocell, then near the RX photocell. Perform this in all operating phases of the control device.

If the control device correctly detects each interruption at all points, the test is successful.

For installations with two or more photocell pairs, repeat the procedure, checking for interference.

Troubleshooting: If the output contact remains closed (does not switch) but the RX LED L3 turns off when the beam is interrupted, there might be an anomaly. Check power supply sufficiency and output relay function. Contact technical support if the problem persists.

7. Maintenance

Perform scheduled maintenance every 6 months, checking the cleanliness and operation of all photocells.

If dirt, moisture, insects, or other contaminants are present, clean the photocells and re-run the test procedure.

Evaluate replacement if oxidation is detected on the printed circuit.
