1 - Warnings
• CAUTION! IMPORTANT INSTRUCTIONS: for personal safety it is important to read and follow these instructions, and store
them in a safe place. In case of doubt, contact Nice Support Service. Incorrect installation is a safety hazard and can lead to
faulty operation.
• Installation, wiring, programming and maintenance must be performed by qualified technicians, in compliance with
the applicable laws, standards, local regulations and these instructions.
• Each element of the device must be anchored permanently to a vertical surface, which must be made of sturdy material and must
not transmit vibrations to the photocells.
Warning! – The surfaces for anchoring the device and the reflector must lie perfectly
parallel to one another; a slight error can be corrected with the orientation system.
• The chosen mounting position must protect
the photocell against accidental impact; it must also allow easy access for maintenance. •
If the photocell is mounted on columns,
make sure that it is fastened to the outer part supporting the column (see Fig. 27
) • The photocells must be connected
exclusively to a Nice control unit (or to an interface) equipped with “BlueBus” technology • The product is protected against rain and
dust infiltrations, and is suitable for outdoor use but not for particularly salty, acidic or potentially explosive atmospheres. Do not
install the equipment in areas subject to flooding or water stagnation. • The power cables must enter the photocell through one of the
holes on the lower section of its support and must be inserted from below to prevent water from penetrating inside. •
Only for US market: Read and follow all operating and installation instruction. Install the EPMORB reflective photocell
according to instructions from the gate and door operator manufacturer. The intent of External Entrapment Protection Device
Type B1 non-contact sensor is to protect a person from being accidentally injured by the moving gate or door. Disable the gate
so it is unable to move.
2 - Description and intended use
EPMORB (EPMORB/A) devices include a receiver-transmitter element (photocell) and a reflector; they are able to detect obstacles
along the line of sight between the two elements. EPMORB (EPMORB/A) devices are presence sensors for automations of doors,
gates, garage doors and similar equipment (Type D according to the EN 12453 standard). It is part of the
Era-EP
series and is
designed for being 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 uses “BlueBus” technology, which enables the connection and
communication among the photocells and the command control unit (or interface) with two wires. The connection is made “in parallel”;
each photocell is associated with a specific function in the automation, through the insertion of a few jumpers. The product may be
used together with “FT210B” series devices, equipped with the “BlueBus” technology (see
Figures 22 and 23
), which enable the
resolution of problem of electric connection with the sensitive edges installed on moving door leafs.
Only for US market: The EPMORB reflective photocell is an external entrapment protection device Type B1, non- contact
sensor for use with automatic gates and doors and complies with UL 325 requirements.
3 - Installation and electrical connections
Correct operation can be influenced by several factors: the position of the devices and their closeness to systems lacking
interference suppressors; other similar devices may interfere during adverse weather conditions. Do not install the device
too close to the ground or near large-size metal objects. The maximum length of any connection cables must not exceed 20 m.
Contact the Nice technical assistance service in case of malfunctions.
If the photocell is mounted on columns, make sure that it is fastened to the outer part supporting the column (see Fig. 27)
01.
Check that the installation conditions are compatible with the data appearing in Chapters 1 and 8.
02.
Shut off power to the automation.
03.
Perform operations from
Fig. 1 to Fig. 9
to install the photocells and the reflector.
04.
Consult the instruction manual for your control unit (or interface) (or F
igs. 22, 23, 24, 25 and 26
) to choose the detection
function and the corresponding installation position, to be assigned to the pair of photocells. Note their identification code number
(e.g. “PHOTO 2”). • To use one or two photocells as the automatic opening control device, choose either the FA1 and/or the FA2
functions.
Warning!
-
We suggest being careful not to arrange the TX devices of the standard BlueBus photocells in front of
the EPMOR BB reflective photocells.
05. Identify in Table A the identification code chosen previously (e.g. “PHOTO 2”); observe the diagram shown below the code and
insert the jumpers in the photocell, in the same position shown in the diagram.
06. If further pairs of photocells must be installed, repeat points 03 and 04 for each. Warning! – Each photocell must use a different
jumper configuration than the one used for the other photocells in the automation.
07. Attach the photocell bracket to the wall in the pre-defined position.
Warning!
– The two elements must be aligned along the same
axis (
Fig. 13
), so as to favour the successive optical alignment between the TX photocell and the reflector. If the walls do not
facilitate this alignment, we recommend, at this stage, attaching the photocell brackets and the reflector provisionally (using
adhesive tape or other method) and fasten them definitively at a later stage, only once testing has been completed (Chapter 4).
Note
– Only for singleor double-leaf sliding gates
– To avoid interference between the various “BlueBus” devices present, position the
components as indicated on the tags in Fig.
22
or
23.
08.
Disconnect the power from the automation and if present, disconnect the back-up battery.
09.
Connect the RFX components in “parallel” (
Fig. 18
) using a twowire bus cable; lastly, connect the bus cable to the “BlueBus”
terminal on the control unit (or interface): it is not necessary to match the poles.
10. Photocells used as an “automatic opening control device”
– If the photocells have been configured for this function (verify at point 04), complete their installation by cutting the electrical
bridge between points “A” on the RFX circuit board (
Figs. 14 and 15
).
11.
Fasten the RFX modules onto their brackets.
12.
Power the automation and perform the “‘BlueBus’ device learning procedure”, found in the control unit (or interface) instruction
manual.
Note
– If this photocell is going to be used to replace a previously existing photocell, the jumpers must be positioned in the
same manner as before. In this case the device learning procedure is not required.
13.
Perform the test procedure as described in Chapter 4.
14.
Complete the installation as shown in
Fig. 17.
4 - Testing
To verify that the photocells are operating properly or to detect any interference with other devices, proceed as follows:
01
. Power the automation and observe the status of the LED positioned on the RFX (
Fig. 19
); find out the meaning of the status in
Table B, bearing in mind that optimal operation only occurs when the LED flashes very slowly. If the detected status is not conforming,
perform the actions indicated in Table B. More specifically, if the alignment between the TX and the reflector must be improved, shift
the photocells slightly until they point at one another, that is, until the LED starts flashing very slowly (= optimal mutual alignment).
(
Fig. 10, 11, 12, 13
)
02.
Check the detection efficiency by blocking the line of sight between the photocell and the reflector using a cylinder (Ø = 5 cm; L =
30 cm): first pass the object near the TX photocell then near the reflector and, lastly, halfway between the two elements (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.
03.
Verify correct obstacle detection as envisaged in the EN 12445 standard, using a parallelepiped (700 x 300 x 200 mm) with three
faces (one for each dimension) with matt black surface and the remaining faces with glossy reflective surface (Fig. 21).
Warning!
– After having added, removed or replaced any automation photocells, the entire automation system must be tested,
referring to the manuals for each of the different devices.
5 - Warnings for use
Warning!
– The photocells do not constitute actual safety devices. They are only auxiliary safety devices. 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 warnings: • Transit can only occur 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 notice any sign of malfunction,
immediately shut off power to the automation and use the manual mode only (refer to the automation’s instruction manual).
Immediately contact a person qualified to inspect and repair the device.
6 - Maintenance
Service the photocells at least every 6 months as follows: 1) release the gearmotor as described in the user manual to prevent
involuntary activation of the automation during maintenance; 2) check for humidity, oxidation and foreign bodies (insects, etc.) 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 detergents containing alcohol, benzene, abrasives or similar cleaning products; these may dull polished
surfaces and hinder the operation of the photocells; 4) run the functional test as described in Chapter 4 - Testing; 5) the product is
designed to work for at least 10 years in normal conditions; we recommend increasing the frequency of maintenance thereafter.
7 - Disposal
This product is an integral part of the automation system and must therefore be disposed of together with it, in the same manner
described in the automation’s user manual.
