Pair of “PH1” photocells
Warnings
• The installation, testing and set-up of automation devices for doors and gates must
be performed by qualified and experienced personnel who must also determine
the type of tests required based on the risks involved, and ensure that laws, stan-
dards and regulations in force are complied with.
• MHOUSE disclaims responsibility for any damage resulting from improper use of
the product; the only use authorized by the manufacturer is the one described in
this manual.
• The packaging materials must be disposed of in compliance with the regulations
locally in force.
• The photocell must not be immersed in water or any other liquid substances. If liq-
uid substances should penetrate inside the device, disconnect the power supply
immediately and call MHOUSE customer service; using the device under these
conditions could be hazardous.
• Do not install the photocells near heat sources or expose them to open flames; this
could damage the device and cause malfunctions, fire hazards or dangers.
Description and intended use
This set of PH1 wall-mounted photocells (Fig.1) is a motion sensor for automatic
gates (D-type according to EN 12453 standard) designed to detect obstacles locat-
ed on the optical axis between the transmitter (TX) and the receiver (RX). The set may
only be used in combination with MHOUSE control units featuring ECSBus-type
connections.
Installation
Warning: disconnect the power supply to the system before performing any instal-
lation operations; if the system is equipped with a PR1 buffer battery, the latter must
be disconnected.
Observe the following directions when selecting the installation position of the two
elements that make up the photocell (TX and RX):
•
Place them at a height of 40-60 cm from the ground, on both sides of the area to be
protected and as flush with the gate as possible (the offset must not exceed 15 cm.).
• The point of installation must be provided with a conduit for the wires.
• Point the TX transmitter at the RX receiver, with a maximum misalignment of 5°.
1. Remove the glass front [A] shown in Fig.2 by prising it out at the bottom with a
slotted tip screwdriver.
2. Press the lens with your finger in order to separate the two shells (Fig.3).
3. Position the photocell at the point reached by the cable conduit [D].
4. On the back element, pierce two of the four holes [B] shown in Fig.4 using a
screwdriver, then mark the drilling points using the back element as reference.
5. Drill the holes in the wall using a hammer drill fitted with a 5 mm bit and insert the
5 mm anchors in the wall.
6. Fasten the back element with the screws [C] as shown in Fig.4, make sure that
the hole in the back [D] Fig.4 matches the outlet of the cable conduit from the wall.
7.
Connect the electric cable to the appropriate terminals on the TX and RX units (Fig.5).
Electrically, TX and RX must be connected to each other in parallel (Fig.6) and to the
blue terminal on the control board. It is not necessary to observe any polarity.
8. Fasten the cover shell [E] shown in Fig.7 using the two screws [F] Fig.7 and a
Phillips screwdriver. Finally, insert the glass front [G] Fig.7 pressing it down gently.
Addressing
To ensure the correct recognition of the photocells by the control unit, the photocells
must be addressed by means of jumpers. Addressing not only ensures their correct
recognition in the ECSBus, but also serves to assign the detection function. The address-
ing operation must be performed on both TX and RX (the jumpers must be positioned
alike), making sure that there are no other pairs of photocells having the same address.
• If the photocell is used to replace a pre-existing one, the jumpers must be set
exactly as they were in the old photocell.
• Any unused jumpers must be stored in their designated compartment for future
use (Fig.8).
• Since every automation system has its own individual characteristics, the photo-
cells can be positioned at various points to perform different detection functions.
Check Fig.9, Fig.10 and Fig.11 to identify the appropriate locations, and position
the jumpers as illustrated in table 1.
SLIDING GATE: MhouseKit SL1 (Fig.9)
SWING GATE: MhouseKit WU2; WK2; WG2 (Fig.10)
GARAGE: MhouseKit GD1; GD2 (Fig.11)
Note: only photocell “A” can be used on automations with MhouseKit GD1.
Table 1
Note regarding photocell “G”: there are normally no restrictions concerning the posi-
tion of the two elements that make up the photocell (TX-RX). However, when photo-
cell G is used in conjunction with photocell B the elements must be positioned as
shown in the Fig.9.
Device recognition
If the photocell is used to replace a pre-existing one, no recognition procedure needs
to be carried out. However, if you add or remove devices connected to the ECS Bus,
the recognition procedure has to be carried out. In this case proceed as follows:
1. On the control unit, press and hold down button P2 [H] shown in Fig.12 for at
least three seconds, then release the button.
2. Wait a few seconds until the control unit has completed the device recognition process
3. When the recognition procedure has been completed, the P2 LED [I] shown in
Fig.12 will go off. If the LED flashes it means that something is wrong.
Checking the operation of the device
After completing the recognition procedure, check whether the SAFE LED [L] Fig.13
on the photocell (both TX and RX) starts flashing. See table 2 to identify the status of
the photocell based on the type of flashing.
Table 2
Testing
Warning: after adding or replacing any photocells, you need to test the entire
automation system anew following the instructions found in the relevant installation
manuals under the “Testing and set-up” chapter.
• To check the photocells and make sure that there is no interference with other
devices, pass a 5 cm diameter, 30 cm long cylinder (Fig.14) on the optical axis, first
near TX, then near RX and finally at the mid-point between them and make sure that
in all these cases the device is triggered, switching from the active to the alarm sta-
tus and vice-versa; finally, that it causes the intended action in the control unit, for
example that it causes the reversal of the direction during the closing manoeuvre.
