Introduction to instructions and warnings
- This manual is intended only for qualified technical staff in charge of machine installation.
- The information in this manual is not intended for the final user. This manual refers to the synchronized photocells R90/ F2ES, G90/F2ES, G90/F2ESI, G90/F2ES/TRIX/TX, and G90/F2ES/TRIX/RX and must not be used for any other product.
- Read this section thoroughly before installing the machine. The installation must be performed only by qualified technical personnel by relevant legislation. Perform connections with cables that are adequate for the current and voltage requirements and comply with product specifications. In order not to affect their proper functioning, the photocells must operate without using reflections and must not interfere with other photocells, whether they be of the same or different types. Interferences may occur between pairs of not-synchronized photocells with tension 12/24V ac-d, among more than two pairs of synchronized photocells with tension 12/24Vac, or with other devices that emit infrared light. Take all the necessary precautions to eliminate this problem. To better understand the issues related to reflection and interference, see Figure 4.
Product description
- The synchronized photocells versions R90/F2ES, G90/F2ES, G90/F2ESI, G90/F2ES/TRIX/TX and G90/F2ES/TRIX/RX are presence detectors based on infra-red technology, which allow detecting obstacles on the optical axis between the transmitter and receiver photocells; they can be used for automatic entries, for courtesy services and monitoring passageways.
- Within these instructions, the transmitter photocell is referred to as the TX photocell, the receiver photocell is referred to as the RX photocell, while one or more pairs of photocells (always consisting of an RX and a TX photocell) will be referred to as photocells.
- These photocells are intended for installation on fixing surfaces flat and parallel to each other, which enable the proper centring between the TX and the RX photocells.
Versions available:
- R90/F2ES and G90/F2ES for external fixing installation.
- G90/F2ESI for installation inside 60mm diameter round boxes. G90/F2ES/TRIX/TX and G90/F2ES/TRIX/RX only installation with TRIX series columns.
Terminals and signalling
- Terminals for photocell TX (see figure 1):
- 1: positive supply 24Vdc, supply 24Vac
- 2: negative supply 24Vdc, supply 24Vac
- LED for TX signalling photocell (see figure 1):
- PW: turned on when supply voltage is present, if off, indicates that the power supply is missing or is incorrectly connected.
- Terminals for photocell RX (see figure 1):
- 1: positive supply 24Vdc, supply 24Vac
- 2: negative supply 24Vdc, supply 24Vac
- 3,4,5: OUTPUT. Normally closed contact (terminals 3-4) with working photocells and no obstacles between TX and RX. Normally open contact (terminals 4-5) with working photocells and no obstacles between TX and RX.
- LED for RX signalling photocell (see figure 1):
- L: indicates the condition of the output contact, its brightness is proportional to the received signal strength, it turns off when there is an obstacle between the photocells (contact open).
- Selecting the supply voltage of the photocells, 12/24V AC/DC. The photocells are always delivered prearranged for a 24V AC/DC power supply.
- To power the photocells 12V ac/dc is necessary to short-circuit by means of tin whiskers the pads C (see Figure 3) at the rear of the printed circuit boards of the photocells.
Installation
Caution: Before installing the photocells, check the compatibility and technical specifications of the control devices to which they will be connected.
Mounting
- Open the photocells, pull out the electronic circuit cards (see figures 5, 6, 7, 8).
- Choose the location of the photocells.
- Attach the bottom of the shell.
- For the G90/F2ES/TRIX/TX and G90/F2ES/TRIX/RX: versions, fix the head (detail I, Figure 8) to the column TRIX with the screws provided. Place the card slot (detail M, Figure 8) on the head.
- WARNING: the TX and RX lower shells are different from each other, check the embossed writing on the back prior to fixing.
Wiring
- WARNING: Connect wires with the power turned off.
- Arrange the cables: there are needed 2 wires to connect a TX and a maximum of 4 wires to connect a RX.
- If needed, connect the output terminals.
- Connect the power supply, ensure the correct polarity.
- Continuous current photocells power supply 12/24Vdc. Connect the 12/24Vdc power supply to the terminals of the photocells according to the polarity of the supply, as indicated in Figure 1.
- Warning: the synchronization in continuous current cannot activate, while the presence or absence of jumpers P1 in TX photocells is irrelevant.
- Alternate current photocells power supply 12/24Vac 50Hz Connect the power supply 12/24Vac 50Hz to the terminals of the photocells with no obligation of connecting the phases, as indicated in the figures 1 and 2,c heck the connection of the jumper P1 for TX photocells, its absence enables the synchronization and requires the phased connection, as indicated in figure 1 and 2.
- Synchronization of one photocell pair
- The synchronization allows installing two pairs of photocells very close to each other with no interference problems.
- To enable the synchronization remove the P1 jumpers inserted in the two TX photocells, connect the 12/24Vac 50Hz power supply to terminals 1-2 of the photocells, with the obligation of connecting the phases as indicated in the figures 1 and 2. If the phase connection has not been properly carried out, the photocells will not function.
- Checking the proper alignment between photocells
- The RX photocell has one red LED indicated with L in figures 1 and 2. Its brightness is proportional to the received signal strength, and it also indicates the correct alignment between photocells. The higher the brightness, the greater the power received and the better the alignment performed. Even though the RX photocell works even with the poor signal received, it is recommended to run the best possible alignment to ensure an efficient operation even in the case of fog, dust, or rain.
Container closure
To close the photocell container, proceed as follows:
R90/F2ES
- Check that the seal (detail A, figure 5) is properly inserted in the upper shell.
- Position the top shell and secure it using the two supplied screws. G90/F2ES
- Place the gasket (O-ring, detail C, figure 6) in the groove of the upper shell.
- Position the gasket (detail D, figure 6) and the upper shell and secure with the two supplied screws.
- Gently press the mask (detail E, figure 6) until it clicks.
G90/F2ESI
- Place the gasket (O-ring, detail F, figure 7) in the groove of the upper shell.
- Position the gasket (detail G, figure 7) and the upper shell and secure with the two supplied screws.
- Gently press the mask (detail H, figure 7) until it clicks.
G90/F2ES/TRIX/TX and G90/F2ES/TRIX/RX
- Place the gasket (O-ring, detail N, figure 8) in the groove of the upper shell.
- Position the gasket (detail O, figure 8) and the upper shell and secure with the two supplied screws.
- Gently press the mask (detail P, figure 8) until it clicks.
Testing
Testing of onphotocellspair
- Testing allows verifying the correct operation of the photocells and of possible interference caused by other nearby devices with infra-red emission.
- Enable the control device to which the photocells are connected.
- With a cylindrical object having about 50mm diameter, cut the infra-red light beam several times between the photocells. Repeat the same operation by positioning yourself near the TX photocell, then near the RX photocell and then between them. If the control device detects correctly each interruption at all points, the test is successfully completed.
- When installing two or more pairs of photocells, repeat the same procedure, taking care to check for any interference between them.
Maintenance
- Perform scheduled maintenance every 6 months and verify the cleanliness and working of all photocells.
- In the presence of dirt, moisture, insects or anything else, clean the photocell and run again the test procedure.
- If oxidation is detected on the printed circuit, evaluate its replacement.
