IMPORTANT NOTICE FOR THE INSTALLER
GENERAL SAFETY INSTRUCTIONS
1) WARNING! For reasons of safety, all the instructions in this manual must be observed scrupulously. Improper installation
or misuse of the product may result in serious injury.
Read the instructions carefully before installing the product.
2)
3) Packaging material (plastic, polystyrene etc.) is a potential hazard and must be kept out of reach of children.
4) Keep these instructions for future reference.
5) This product has been designed and manufactured only for the use stated in this manual. Any use other than that
expressly indicated may result in damage to the product and/or risk of injury.
6) FAAC S.p.A. shall not be liable for any damage or injury caused by improper use of the automation or by any use other
than that for which it is intended.
7) Do not install this device in explosive atmospheres: the presence of flammable gas or fumes is a serious hazard.
8) Mechanical structural elements must comply with UNI8612, CEN pr EN 12604 and CEN pr EN 12605 standards.
For countries outside the EC, mechanical structural must comply with the above standards in addition to any national
safety standards, in order to obtain a reasonable degree of safety.
9) FAAC cannot be held responsible for failure to observe technical standards in the construction of the gates on which
the automation is installed, or for any deformation of the gates which may occur during use.
10) Installation must comply with UNI8612, CEN pr EN 12453 and CEN pr EN 12635.
The degree of safety of the automation must be C+D.
11) Before carrying out any operations on the system, disconnect the electrical power supply.
12) Install a multi-pole switch on the supply line to the automation with a contact opening distance of 3 mm or more. We
recommend the use of a 6A thermal magnetic circuit breaker with multi-pole switching.
13) Ensure that a residual current device with a trip threshold of 0.03A is installed upstream of the automation system.
14) Check that the earthing system is installed correctly and is efficient. Connect the metal parts of the gate and the
yellow/green wire of the operator to the earthing system.
15) The automation is fitted with an anti-crushing safety system consisting of a torque control device which, in all cases,
must be used in conjunction with other safety devices.
16) The safety devices (e.g. photocells, safety edges, etc.) protect areas where there is a mechanical movement hazard,
e.g. crushing, entrapment and cutting.
17) Each installation must be fitted with at least one flashing light (e.g. FAAC LAMP, MINILAMP etc.) and a warning sign
suitably fixed to the gate, in addition to the safety devices as per point 16 above.
18) FAAC cannot be held responsible for the safe and correct operation of the automation in the event that parts other
than FAAC original parts are used.
19) Use only FAAC original spare parts for maintenance operations.
20) Do not carry out any modifications to automation components.
21) The installer must supply all information regarding manual operation of the system in the event of an emergency and
provide the end-user with the "End-user Guide" supplied with the product.
22) Do not allow any persons, especially children, to stand in the vicinity of the automation when in operation.
23) Keep the remote radio controls and any other control devices out of the reach of children to prevent accidental
operation of the automation.
24) The end-user must not attempt to repair or adjust the automation. These operations must be carried out exclusively
by qualified personnel.
25) Any operations not explicitly described in these instructions are not permitted.

AU T OMATION 844 MC-R & 844 MPSR
These instructions apply to the following models:
844 MC-R
The FAAC model 844MC-R automation for sliding gates is an
electromechanical operator which transmits movement to
the gate leaf by means of a rack and pinion coupled in an
where:
Ta = opening time
Tc = closing time
Tp = pause time
interval between one complete cycle and the next.
Ti =
appropriate manner to the sliding gate.
The reversible system allows the gate to be moved manually
when the motor is not in operation. An electric lock must
therefore be installed to ensure that the gate cannot move
when closed.
The gear motor is equipped with an adjustable mechanical
clutch which affords the necessary anti-crushing safety. A
convenient manual release device allows the gate to be
operated in the event of mechanical problems with the gear
motor. The electronic control unit may be housed inside the
operator or in a separate box.
The automation 844MC-R has been designed and built for
vehicle access control. Do not use for any other purpose.

1.1. MAXIMUM UTILISATION CURVE
The curve allows the maximum working time (T) to be obtained
as a function of duty cycle (F).
E.g.: the 844 MC-R operators can work continuously at a duty
cycle of 30%.
To ensure good operation, keep to the field of operation lying
below the curve.
Important: The curve refers to a temperature of 24°C. Exposure
to direct sunlight can result in a reduction in duty cycle to as
low as 20%.
The duty cycle is the percentage of effective working time
(opening + closing) with respect to the total cycle time (opening
+ closing + pause times).
It is calculated using the following formula:
%F =
i Adjusting screw for anti-crushing clutch
j Bore for access to oil filler cap
k Cover lock operated with triangular key
l Operator ground connection
m Bores for passage of connection cables
n Release lever
o Fixing bar cover

closure) to ensure that the pinion and rack mesh correctly.
3) Prepare a foundation plinth as shown in Fig. 7 and install the
base plate providing one or more conduits for electrical
cables. Use a level to check that the plate is perfectly
horizontal and wait for the cement to set.
4) Lay the electrical cables for connection to the accessories
and the electricity supply as shown in Fig. 3. For ease of
connection, ensure that the cables protrude by about
45 cm from the hole in the base plate (Figs. 5-6 ref.1).

4. INSTALLING THE AUTOMATION
4.1. PRELIMINARY CHECKS
For safe, correct operation of the automation, make sure that
the following requirements are met:
• The gate’s structure must be suitable for automation. Take
special care to ensure that the wheels are large enough to
support the full weight of the gate, that a top runner is
installed and that physical stops are fitted to prevent the
gate from coming off the runner.
• Make sure that the bottom runner is perfectly horizontal. If
it slopes, the fact that the gear motor is reversible may allow
the gate to move on its own.
• The characteristics of the ground must ensure sufficient
support for the foundation plinth.
• There must be no pipes or electrical cables in the area to be
dug for installing the foundation plinth.
• If the gear motor is located in a vehicle transit area, it is
advisable to provide protection against accidental collisions.
• Check that the gear motor has an efficient earth connection.
4.2. INSTALLING THE BASE PLATE
1) Assemble the base plate as shown in Fig.4.
2) The base plate must be positioned as shown in Fig. 5 (righthanded closure (right-handed closure) or Fig. 6 (left-handed
