Pair of "PH0" photocells
Warnings
• Installation, testing and commissioning of automations for doors and gates must be
performed by qualified and skilled personnel, responsible for establishing the tests
envisaged and to verify observance of relative legislation, standards and regulations.
• MHOUSE denies all liability for damage deriving from improper use of the prod-
uct and use other than as specified in this manual
• Packaging material must be disposed of in full observance of current local stan-
dards.
• Ensure that photocells are never immersed in water or other liquids.
In the event of penetration of liquids in the device, disconnect the power supply
immediately and contact a MHOUSE service centre; use of the device in these
conditions constitutes a hazard.
• Keep photocells away from sources of strong heat and ensure that they are not
exposed to flames; these conditions may damage the devices and cause mal-
functions, fire or hazardous situations.
Product description and intended use
The pair of wall-mounted photocells PH0 (Fig. 1) is a presence detector for
automations of gates (type D according to standard EN 12453); it enables the
detection of obstacles located on the optic axis between the transmitter (TX) and
receiver (RX).
Installation
Caution: all installation operations must be performed with the power discon-
nected from the system; if the PR1 buffer battery is present, this must also be dis-
connected. Select the position of the two elements of the photocell (TX and RX)
according to the following provisions:
• Set them at a height of 40-60cm from the ground for automations with hori-
zontal movement, 20-25cm from the ground for those with vertical movement,
on the sides of the area to be protected and as close as possible to the gate
edge, not exceeding 15cm, refer also to the chapter "testing".
• In the case of sectional doors, the photocells can be placed both on the interi-
or or exterior, while in the case of protruding up-and-over doors, they may only
be positioned on the interior (if placed on the exterior they would intercept the
door in movement).
• The 2 envisaged points must be fitted with ducting for cable routing.
• The transmitter TX must be pointed at the receiver RX with a maximum align-
ment offset of 5°.
1. Using a slotted screwdriver, lever off and remove the front glass panel [A] (of Fig.
2) on the lower section
2. Press on the lens with the index to separate the two shells (Fig. 3)
3. Position the photocell at the point of arrival of the cable ducting [D] (Fig. 4).
4. On the base, pierce two of the four holes [B] of Fig. 4 using a screwdriver, trace
the drilling points using the base as a reference.
5. Drill the wall using a percussion drill and 5mm tip and insert the 5mm plugs.
6. Secure the base with screws [C] (of Fig. 4) taking care that the hole on the base
[D] (of Fig. 4) is aligned with the cable exit from the wall.
7. Connect the electrical cable in the relative terminals for TX and RX.
Make the electrical connections on the basis of the required function, as spec-
ified in the automation manuals and the indications in Fig. 5.
8. Fix the covering shell [E] (of Fig. 6) with the two screws [F] (and Fig. 6) and
Phillips screwdriver. Insert the glass panel [G] (of Fig. 6) exerting a slight pres-
sure to close.
Testing
Caution: after adding or replacing photocells, testing must be repeated on the
entire automation as envisaged in the relative installation manuals in the chapter
"Testing and Commissioning".
• Power up the pair TX and RX of F210, do not place any obstacles between TX
and RX and check table 1 to verify the photocell status on the basis of the type
of flash of led "L" on the receiver (Fig. 7)
• To check the photocells, and in particular to ensure there is no interference with
other devices, pass a cylinder (Fig. 8) with a diameter of 5cm and length of 30cm
on the optical axis, first close to the TX, then close to the RX and lastly at the
centre between the two and ensure that in all cases the device engages, chang-
ing from the active status to alarm status and vice versa; lastly that the envis-
aged action is generated on the control unit, for example: in the closing
manoeuvre it inverts movement.
Caratteristiche Tecniche
PH0 is manufactured by NICE S.p.a. (TV) I, MHOUSE S.r.l. is a company of the
group NICE S.p.a.
For purposes of product improvements NICE S.p.a. reserves the right to modify
technical specifications at any time and without notice, while maintaining a guar-
antee of the intended use and functions.

PH0 adjustable photocells
Product type: Presence detector for automations of automatic gates and doors
(type D according to standard EN 12453) comprising a pair of "TX" transmitter and
"RX" receiver photocells
Technology adopted: Direct TX-RX optical interpolation with modulated infrared
beam
Power supply: without jumper: 24Vac/Vdc (limits 18÷35Vdc,15÷28Vac)

• Check correct obstacle detection using the test parallelepiped of
700x300x200mm with 3 matt black sides and 3 gloss white sides or the oppo-
site configuration as envisaged by standard EN12445 (see fig.9)
Further details
In the case of two pairs of photocells placed close together, the range of a trans-
mitter may interfere with the other receiver (fig.10) reducing the guarantee of ade-
quate safety. To remedy this situation, only in the case that AC power supply is
available, the synchronisation system can be used, which enables alternate use of
the two pairs of photocells.
This system cuts the synchronisation jumper "SINC" on the two TX (see fig 11) and
the pair of photocells (TX and RX) is powered with the phases inverted with respect
to the 2nd pair. (see fig 5b).
• Photocells PH0 can be powered, if required, with 12V rather than 24V; to enable
this, a watertight jumper must be made between the two "12V" points both on
TX and RX (see fig11).
• If the distance between TX and RX exceeds 10 metres, cut the jumper between
the points "+10m."of RX (see fig11).
Maintenance
Photocells do not require special provisions, but should be inspected at least every
6 months to check conditions (presence of humidity, oxidation, etc.), after which
the external casing and lenses should be cleaned and testing as described in the
above section should be repeated. The photocells have been designed to operate
in normal conditions for at least 10 years, after which maintenance should be
scheduled at more frequent intervals.
