PRODUCT DESCRIPTION
AND INTENDED USE
MC824H is an electronic control unit for the automation of swing gates. CAU-
TION! – Any other use than as specified herein or in environmental condi-
tions other than as stated in this manual is to be considered improper and
is strictly prohibited!
The control unit is ready for connection to external devices by means of the
Bluebus system and for connection to devices belonging to the Opera System
produced by Nice.
The control unit is designed for use of a buffer battery (model PS324, optional
accessory), which ensures that the automation can perform a number of
manoeuvres in the event of a power failure.
Other available accessories are the SMXI, OXI and OX2 receivers.

INSTALLATION
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 material used is in perfect condition and suitable for use.
• Ensure that all conditions of use remain within the limits of product application
(paragraph 2.2).
• Ensure that all parameters of use remain within the limits as stated in the
"Product technical specifications".
• Ensure that the selected installation environment is compatible with the over-
all dimensions of the product (fig. 1).
• Ensure that the selected surfaces for product installation are solid and guar-
antee a stable fixture.
• Ensure 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.
• Ensure that all the electric cables used are of the type listed in Table 1.
• Ensure that the automation is provided with mechanical stops on both clos-
ing and opening.
2.2 - Product application limits
The product may be used exclusively with gearmotors METRO (model ME
3024), MOBY (model MB4024-MB5024), HYPPO (model HY7124) and TOO -
NA (model TO4024-TO5024-TO7024).
2.3 - Installation
To install the control unit, proceed as shown in fig. 2. To install the other
devices present in the automation, refer to the relevant instruction manuals.
Connection
A: CONTROL UNIT POWER cable
B: FLASHING LIGHT with aerial cable
C: BLUEBUS DEVICES cable
D: KEY-OPERATED SELECTOR SWITCH cable
E: GEARMOTOR POWER cable
F: ENCODER CONNECTION cable
Note 1 – If the power cable is longer than 30 m, a cable with a larger cross-section is required (3 x 2.5 mm
of the automation.
Note 2 – If the Bluebus cable is longer than 20 m (up to max. 40 m), a cable with a larger cross-section is required (2 x1 mm
Note 3 – These 2 cables can be replaced by a single 4 x 0.5 mm
Note 4 – These cables can be replaced by a single 5 x 1.5 mm
CAUTION! – The cables used must be suited to the installation environment.
CAUTION! – All electrical connections must be made with the unit dis-
connected from the mains power supply and with the buffer battery dis-
connected, if present in the automation.
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. 3 and connect
3.1 - Initial start-up and electrical connections
CAUTION! – Connections must be made exclusively by qualified personnel.
After powering up the control unit, perform the following checks:
• After a few seconds, make sure that the "Bluebus" LED flashes regularly, with
• Make sure that the LEDs on the photocells flash (both on TX and RX). The
• Make sure that the flashing light connected to the FLASH output is off.
If the above conditions are not satisfied, switch off the power supply to the con-
trol unit and check the electrical connections.

IMPORTANT! – If the system has a single gearmotor, it must be connect-
ed to terminals 10, 11, 12.
3.3 - Connected device address assignment
To enable the control unit to recognise the devices connected to the Bluebus
system, they must be assigned addresses. This operation must be performed
by positioning the electric jumper as described in the instruction manuals of
each individual device.
