• Activation of the "PHOTO 1" pair of photocells stops both the opening and
closing manoeuvres.
• Activation of the "PHOTO2" pair of photocells (connected to the suitably pro-
grammed AUX input) has no effect during closing while they invert movement
during opening.
To check the parts of the control unit see fig. 2.

2.1 - Preliminary checks for installation

Before proceeding with installation, check the condition of the product compo-
nents, suitability of the selected model and conditions of the intended installa-
tion environment:
• Ensure that all conditions of use remain within the limits of product application
and within the "Product technical specifications".
• Ensure that the selected installation environment is compatible with the over-
all dimensions of the product (fig. 3).
• Ensure that the selected surfaces for product installation are solid and guar-
antee a stable fixture.
• Make sure that the fixing zone is not subject to flooding. If necessary, mount
the product raised from the ground.
• Ensure that the space around the product enables easy and safe completion
of manual manoeuvres.
• Make sure that the automation is provided with mechanical stops on both
closing and opening.

2.2 - Product application limits

The product may be used exclusively with WG4024, WG5024, XME2024,
TN2020, TN2020L, TOO3024, TOO4524 gearmotors.

Note 1 – This is not used for single leaf gates (the control unit automatically recognises if only one motor has been installed) .
Note 2 – The "Everything in stand by" function serves to reduce consumptions . For further details on the electrical connections refer to paragraph 2 .4 .1 ""Every-
thing in stand by/Phototest connection" and for programming refer to chapter 5 .2 .3 "Everything in stand by/Phototest function" .
Note 3 – The STOP input can be used for "NC" or constant resistance 8.2 kΩ contacts (please refer to the "Programming" chapter)
Note 4 – The AUX factory auxiliary input is programmed with the "Partial open type 1" function but can be programmed with any of the following functions:

ing warnings:
• The control unit is supplied in an enclosure that if correctly installed assures
an IP54 protection rating. The control unit is therefore suitable for installation
outdoors.
• Fix the control unit to a flat, vertical, non-removable surface that is adequately
protected from potential impacts. Important! – The bottom of the control unit
must be at least 40 cm from the ground.
• Insert the dedicated cable clamps or pipe glands into the lower part of the
enclosure (fig. 4). Important! – If the cable protection tubes end in a pit, it is
likely that condensation will form inside the control unit, which will damage the
electronic board. In this case, protect the control unit adequately so as to pre-
vent the formation of condensation.
• The cable clamps can be inserted on the long side of the enclosure only if the
control unit is installed in a protected indoor environment.
To install the other devices present in the automation, refer to the relevant
instruction manuals.

2.4 - Electrical connections

IMPORTANT!
– All electrical connections must be made with the unit disconnected
from the mains power supply and with the buffer battery disconnected,
if present in the automation.
– Connections must be made exclusively by qualified personnel.
– Make sure that all the electric cables used are of a suitable type.
01. Loosen the screws of the cover.
02. Prepare the electrical cable routing holes.
03. Connect the cables as shown in the wiring diagram in fig. 5. To connect
the electric power cable, see fig. 6. Note – To facilitate cable connections,
the terminals can be removed from their seats .
• With the exception of the photocell inputs when the PHOTOTEST function
is activated, if the inputs of the NC (Normally Closed) contacts are not in use
they should be jumped with the "COMMON" terminal. Refer to paragraph
2.4.3 for further information.
• If there is more than one NC contact on the same input, they must be con-
nected in SERIES.
• If the inputs of the NO (Normally Open) contacts are not used they should be
left free.
• If there is more than one NO contact on the same input, they must be con-
nected in PARALLEL.
• The contacts must be electromechanical and potential-free. Stage connec-
tions, such as those defined as "PNP", "NPN", "Open Collector", etc. are not
allowed.
• If the leafs overlap, use jumper E (Fig. 6) to select which motor starts up first
during opening.
