• close speed
This parameter enables programming of the motor speed during a Closing manoeuvre; it can be set with a value from 1 (mini-
mum speed) to 6 (maximum speed); the factory setting is 6. Parameter programming: select the required value by means of
keys p and q, then press "OK".
• opening deceleration speed
This parameter enables programming of the motor speed during the deceleration phase of an Opening manoeuvre; it can be set
with a value from 1 (minimum speed) to 4 (maximum speed); the factory setting is 2. Parameter programming: select the
required value by means of keys p and q, then press "OK".
• closing deceleration speed
This parameter enables programming of the motor speed during the deceleration phase of a Closing manoeuvre; it can be set
with a value from 1 (minimum speed) to 4 (maximum speed); the factory setting is 2. Parameter programming: select the
required value by means of keys p and q, then press "OK".
Force management
• opening force
This parameter can be set, for each motor, with a value from 1 (minimum force) to 8 (maximum force); the factory setting is 3.
The function enables setting of the maximum force (*) applied by the motors on the leafs during an opening manoeuvre, before
the "obstacle detection" function is activated. If the current required by the motor exceeds the set value, the control unit inter-
rupts the current manoeuvre and if necessary inverts movement. Parameter programming: select the motor (1 or 2), by means
of keys t and u; then select the required value using keys p and q, and press "OK".
• closing force
This parameter can be set, for each motor, with a value from 1 (minimum force) to 8 (maximum force); the factory setting is 3.
The function enables setting of the maximum force (*) applied by the motors on the leafs during a closing manoeuvre, before the
"obstacle detection" function is activated. If the current required by the motor exceeds the set value, the control unit interrupts
the current manoeuvre and if necessary inverts movement. Parameter programming: select the motor (1 or 2), by means of keys
t and u; then select the required value using keys p and q, and press "OK".
(*) Note: the force depends on the electrical current absorption of the motor.
Sensitivity management
• open sensitivity
This parameter can be assigned with a value from 1 (minimum force) and 8 (maximum force); the factory setting depends on the
type of installation. This function enables setting of the maximum force (**) applied by the motors on the leafs during an open-
ing manoeuvre, before the "obstacle detection" function is activated. Parameter programming: select the required value by
means of keys p and q, then press "OK".
• close sensitivity
This parameter can be assigned with a value from 1 (minimum force) and 8 (maximum force); the factory setting depends on the
type of installation. This function enables setting of the maximum force (**) applied by the motors on the leafs during a closing
manoeuvre, before the "obstacle detection" function is activated. Parameter programming: select the required value by means
of keys p and q, then press "OK".
(**) Note: the force depends on the frequency of pulses sent by the encoder.
Start-up
• active
This parameter type is ON / OFF; the factory setting is "OFF". When the function is set to "ON", the manoeuvre starts with the
maximum force and speed values to ensure maximum motor power during the initial phase. The end of the start-up torque
phase is followed by a gradual acceleration ramp. This function is useful in the presence of static friction (e.g. snow or ice) which
obstructs the automation. Parameter programming: select the required value by means of keys p and q, then press "OK".
• start-up time
This parameter is expressed in seconds and can be set with a value from 0 to 3 seconds; the factory setting depends on the
type of motor used. The function enables programming of the duration of start-up torque at the start of a manoeuvre. Parame-
ter programming: select the required value by means of keys p and q, then press "OK".
Important – If the function is active (ON), the start-up torque is enabled on both opening and closing manoeuvres. If the func-
tion is not active (OFF) and the "start-up time" is set to a value other than 0, the start-up torque is only activated for the opening
manoeuvres which start from the gate closed position, and with a duration equal to the set time.
Pre-flash
• active
This parameter type is ON / OFF; the factory setting is "OFF" . When this function is set to "ON" it enables the activation of a
flashing time, which passes between activation of the flashing light and the start of an Opening or Closing manoeuvre. This time
is adjustable and useful to for an advance indication of a hazardous situation. Important – When this function is not active
(OFF), the flashing light is switched on at the same time as the start of the manoeuvre. Parameter programming: select the
required value by means of keys p and q, then press "OK".
• opening time
This parameter is expressed in seconds and can be set with a value from 0 to 10 seconds; the factory setting is 3 seconds. The
