Safety and installation instructions

• CAUTION! IMPORTANT INSTRUCTIONS : for personal safety it is important to read and follow these instructions and to store them in a safe place. In case of doubts, contact the Nice Support Service. Incorrect installation is a safety hazard and can lead to faulty operation.

• The installation, hookup, programming, and maintenance may be done solely by a qualified technician, in observance of established legislation, standards, local regulations, and the instructions given in this manual.

• The photocell must operate exclusively when an object is placed between the transmitting element (TX) and the receiving element (RX): it is not configured for reflection.

• All components must be permanently installed on a vertical wall.
  Caution! ­ The walls must be solid, parallel to each other, and they must not transmit vibration to the photocells.

• The mounting position must protect the photocell from accidental impact; it must also allow easy access for maintenance.

• To increase the level of safety against failure, the pair of photocells must be connected to a control unit equipped with the phototest function.

• The product is protected against water and dust; it is therefore suited for normal outdoors applications. It is however not suited for use in strongly saline, acid, or potentially explosive atmospheres. Do not install the equipment in areas subject to flooding or accumulation of water.

• The electrical cables must enter the photocell via one of the holes in the bottom of its mount and must be inserted from below. This is to prevent water entering the housing.

Product description and intended use

This device is a photocell (e.g. a type D detector pursuant to EN 12453) with relay output. It is part of the Era-EP series, and is intended to be used on automation systems for doors, gates, garage doors, and similar installations. Any use other than that described is to be considered improper and prohibited! The device is composed of a transmitting element and a receiving element which must be mounted facing each other on two vertical and parallel walls. Alternatively, column supports are available (for the compatible models, consult the Nice product catalogue).

Installation and hook up

1. Make sure that the installation satisfies the “Technical specifications”; also read the specific instructions given in Chapter 1.

2. Follow the instructions given in fig. 1, 2, 3, 4, 5, and 6.

3. Shut off power to the automation.

4. Read points A, B, and C and only complete the steps which refer to your automation.
   A ­ 12V power supply. If this power supply voltage is used, it is necessary to make a bridge connection on the TX and RX circuit board (fig. 7) by welding with a lump of tin the two points marked “12V”.
   B ­ Distance between photocells greater than 10m. If the distance between the TX and RX units exceeds 10m, it is necessary to cut on the RX unit circuit board the electrical bridge between the points marked “+10m”, as indicated in fig. 8.
   C ­ Resolving interference problems between pairs of photocells. If two pairs of photocells are installed close together, the TX beam of one pair may be captured by the RX of the other and vice versa (fig. 9), thus resulting in incorrect operation. The problem can be solved by setting the “synchronised mode” and powering the photocells with AC power; to this end, cut the bridge marked “SYNC” on the TX circuit boards (fig. 10) and power one pair of photocells with their wires inverted compared to those of the other pair (fig. 11). · If the interference risk persists, you can reduce the RX reception area by installing the reduction cone (provided) on the RX photocell, as shown in fig. 12, 13, and 14. The cone reduces the field of view to around 8°.

5. Make the electrical hookup shown in fig. 15. To use the photocells as safety devices, connect the cables to the NC contact (terminals 4 and 5); to use them as control devices, on the other hand, connect the cables to the NO contact (terminals 3 and 4).

6. Do as shown in fig. 16.

7. Perform the testing procedures described in Chapter 4.

8. Complete the installation as shown in fig. 22 and 23.

Testing

1. Power the automation and verify the status of the LEDs (fig. 18) on the RX photocell.
   Caution! ­ If the led flashes rapidly or remains lit with a fixed light (see Table A to interpret the LED status), it is necessary to improve the alignment of the TX and RX units as indicated in fig. 17, 18, and 19.
   Note to fig. 18 ­ Point the photocell towards the other photocell: optimal alignment is achieved once the LED turns off or starts flashing very slowly. This procedure can be done on one or both units.

2. Check their operation by blocking the line of sight between them with a cylinder (Ø = 5 cm; L = 30 cm): first pass the object close to the TX, then to the RX, and, finally, halfway between them (fig. 20). Make sure that in each case the output switches from “Active” to “Alarm” and back, and that the automation responds properly to actuation of the photocell.

3. Verify correct obstacle detection as required by the EN 12445 standard, using a parallelepiped (700 x 300 x 200 mm) with three faces (one per dimension) with matt black surface and the others with glossy reflective material (fig. 21).

User warnings

Caution! – Photocells do not constitute actual safety devices, but are rather safety aids. Although constructed for maximum reliability, in extreme conditions they may malfunction or fail, and this may not be immediately evident. For this reason, and as a matter of good practice, observe the following instructions:

• Transit is only possible if the gate or door are completely open and with the leaves stationary.
• NEVER TRANSIT while the gate or door are closing or are about to close.
• If you note any sign of malfunction, shut off power to the automation immediately and use manual mode only (refer to the automation instruction manual). Contact your maintenance staff/person for the control and the possible repair.

Maintenance

Service the photocells at least every 6 months as follows:

1. release the motor as instructed in the user manual to prevent the automation operating unexpectedly during maintenance;
2. check for humidity, oxidation, and foreign bodies (such as insects) and remove them. In case of doubt, replace the equipment;
3. clean the housing ­ especially the lenses and glass panels ­ with a soft, slightly damp cloth. Do not use alcohol, benzene, abrasive, or other cleaning products; these can affect the polished surfaces and compromise the operation of the photocells;
4. run the tests indicated in “Tests”;
5. the product is designed to work for at least 10 years in normal conditions; we recommend increasing the frequency of maintenance thereafter.

Scrapping

This product is an integral part of the automation and must therefore be scrapped together with it, in the same way as indicated in the automation’s instruction manual.
