SPECIAL FUNCTIONS AND PROCEDURES
9.1 - Motor Thermal Cutout function
The motor is designed for residential use, in other words, for intermittent service. It
guarantees maximum continuous operation of 4 minutes and, should it overheat (due
to continuous, prolonged operation) a thermal cutout automatically trips to cut off the
power supply, and resets when the temperature has returned to a normal level. This
function cannot be disabled.
9.2 - Always Open function
The Always Open function is a control unit feature which enables the user to control
an opening manoeuvre when the Step-by-step command lasts longer than 2 sec-
onds. This is useful for connecting a timer contact to the Step-by-step input in order
to keep the door open for a certain length of time, for example. This property remains
in force no matter what value the Step-by-step input is set to, with the exception of
the value "Residential 2" (see Step-by-step inTable E).
9.3 - Move Anyway function
In the event that a safety device malfunctions or is out of service, the gate may still be
moved in "hold-to-run" mode. For details, see par. 4 - "Control with safety devices
out of order" in the "User manual" annex.
9.4 - Deleting the memory
The following procedure allows the memory to be completely deleted, and restores
the factory settings.
01. Make sure the motor is not moving.
02. Hold down [▲] and [▼] together, and release them when all leds light up.
04. The procedure terminates when all leds turn off and leds L1 and L2 continue
flashing.
Caution! – This procedure changes the settings relating to the motor's direction of
rotation (parameter L8 – Level 1 menu).
9.5 - Battery low indication
If the voltage drops below 19.5V when operating the system with the PS124 backup

Description
This function automatically closes the gate after a set pause time; by default the Pause Time is set at 30 seconds,
but can be modified to 10, 20, 40, 60, 80, 120, 160 or 200 seconds. This function is disabled by default. If the
function is disabled, operation is "semiautomatic".
This function enables the system to keep the door open only for the time required for transit, in fact activation
of"Photo" always causes automatic closure with a pause time of 5s (regardless of the set value). This depends
on the status (enabled/disabled) of "Automatic close".
If the "Automatic close" function is disabled, the door always opens fully, even if the photo is released first. On
release of Photo, automatic closure is activated with a pause of 5s.
If the "Automatic close" function is enabled, the opening manoeuvre stops immediately after release of the
photocells and automatic closure is activated with a pause of 5s. The function "Close After Photo" is always
disabled in manoeuvres interrupted by means of a Stop command. If the function "Close After Photo" is disabled,
the pause time is as set; otherwise there is no automatic closure if the function is disabled. This function is
disabled by default.
Closes the door when the door is detected to be open when powered on. For safety reasons, the manoeuvre
is preceded by a 3-second pre-flashing interval. If the function is disabled, the door remains stationary on
restoration of power. This function is disabled by default.
This function enables reduction of consumption to a minimum. If this function is enabled, 1 minute after completion
of the manoeuvre the control unit turns off the BlueBUS output (and therefore the devices) and all leds, with the
exception of the BlueBUS led, which flashes at a slower speed. When the control unit receives a command it
restores full operating conditions. If the function is disabled, no reduction in consumption is enabled. This function
is disabled by default.
The pre-flashing function is added to a pause of 3s between activation of the flashing light and the start of the
manoeuvre to warn of a hazardous situation. If preflashing is disabled, activation of the flashing light coincides
with the start of the manoeuvre. This function is disabled by default.
Automatically sets the motor's force and sensitivity to the weight of the door. It is advisable to enable this function
for heavy doors, for light doors it is better disabled. This function is disabled by default.
Increases the sensitivity of the motor in detecting obstacles along the door's travel. The factory setting is disabled.
Once activated, you can adjust the sensitivity with level 2 programming (par. 8.4). The procedure adjusts the
force of the motor in seeking to overcome the obstacle. If this function blocks the door frequently without any
evident reason, it is better disabled. If the function is used to determine the impact force, you must also regulate
the parameters "Speed" and "Motor force" with level 2 programming (par. 8.4).
Reverses the direction of rotation of the motor and associates the Open and Close commands correctly with the
symbols "▲" and "▼", on the control buttons. This function is disabled by default. Important – If you enable this
function, ytou must memorise the limit positions "0" nd "1" anew.
battery, the battery charge is too low. This is indicated by the courtesy light, which
starts flashing when the door's movement stops.
The indication stops when the voltage returns above 19.5V, or when mains power
is restored.
9.6 - Motor power draw indication
When the automation is operating, leds L1 to L8 act as a Vu meter. This indicates
the power draw at any time. Thus L1 flashing = max draw; L8 flashing = min draw.

MAINTENANCE
10.1 - Maintenance notification
Every 4000 cycles, the controller notifies the user that the system must be serviced.
The notification period can be changed with a Level 2 programming setting (see par.
8.4). Note – The values "L2" to "L8" given in Table E ("Maintenance notification"),
count the number of duty cycles; value "L1" considers the nature of the duty (heavy/
light), i.e. the force employed and the duration of each cycle.
The maintenance notification is given by the flasher. This factory setting can be
changed with a Level 2 programming setting (see par. 8.4), by selecting "Flash out-
put" (in Table E) and setting the "Maintenance lamp" value.
Depending on the number of duty cycles compared to the programmed limit, the
flasher gives the following notifications:
• Flasher signals
Number of cycles
Less than 80% of limit
81 - 100% of limit
Over 100% of limit
• Maintenance indicator signals
Number of cycles
Lower than 80% of limit
81 - 100% of limit
Over 100% of limit
Signal
Normal (0.5s on, 0.5s off)
Stays on at the start of the cycle for 2s, then con-
tinues normally
Stays on at the start and end of the cycle for 2s,
then continues normally
Signal
On for 2s at start of opening
Flashes throughout the cycle
Flashes continually
