These instructions apply to the following models:

MC - 860 MC RF - 860 EMC Z16 - 860 EMC
The FAAC model 820 and 860 automations for sliding gates
are electromechanical operators which transmit movement
to the leaf by means of a pinion with rack or chain coupled
in an appropriate manner to the sliding gate.
The system is guaranteed to be mechanically locked
when the motor is not in operation so a lock does not need
to be installed. The gear motors have mechanical/
electronic clutches which provide the necessary adjustable
anti-crushing safety. A convenient manual release device
allows the gate to be operated in the event of a power
failure or malfunction. An electronic device allows the
open/closed limit switches to be programmed by a simple
operation without the need to weld limit switch plates. The
electronic control unit is incorporated in the gear motors.
The automations 820 - 860 & 826 MPS have 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).
For example, the 820-860 gear motors can operate
uninterruptedly 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%.
Calculating duty cycle
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:
Ta + Tc
%F =
X 100
Ta + Tc + Tp + Ti
where:
Ta = opening time
Tc = closing time
Tp = pause time
Ti =
interval between one complete cycle and the next.
