drives the motors for one second at reduced speed (softstart) and then at the speed set on the FOR trimmer.
- if a command is given during closing the control unit commands the complete re-opening
- closing stops when the limit switch or the obstacle detection system intervenes or when the manoeuvre time has elapsed.

"PEDESTRIAN OPENING" FUNCTION

The pedestrian function can be assigned with the professional learning to channel 2/3/4 of the remote control.
With a "PEDESTRIAN OPENING" ("EDG/EDG" terminal) command on the input, the control unit commands an
opening for the first leaf for a time of:
- 5 seconds if no learning has been carried out,
- complete opening if a simplified learning has been carried out
- that set by the installer if a professional learning has been carried out.
Closing is triggered by a manual command, or automatically if the automatic closing function is enabled. The complete
opening command has always priority over the pedestrian opening, therefore if, during a pedestrian manoeuvre a
complete opening command is received, the control unit will command a complete opening of the automation.
5.7 TRIMMER "OBS" - "OBSTACLE SENSITIVITY" DETECTION
The "OBS" TRIMMER is used to adjust at the same time the delay time of intervention after an obstacle has
been detected and the threshold of the counter-force against the operator necessary to trigger the intervention.
Both the counter-force and the delay time increase when the trimmer is turned clockwise. The delay time
can be adjusted between 0.1 and 3 seconds. This function is useful to overcome any critical points of the
operator which cause a higher power absorption by the motor for a short time.
EXAMPLE
delay time about 0,1 sec.
If electric limit switches are present, the obstacle detector will provoke an inversion of the motion in closing
and a 2 second inversion in opening.
If there are no electric limit switches the obstacle detector provokes:
- in closing an inversion of the motion unless it is in the last five seconds of the manoeuvre, where does a STOP
- in opening an inversion of the motion for 2 seconds unless it is in the last five seconds of the manoeuvre,
where does a STOP.
5.8

FLASHING LIGHT

The control unit has two output terminals (LAMP) to command a low voltage flashing light. The light start flashing 1
second before each opening manoeuvre and 1 second before each closing manoeuvre.
If the dip-switch 5 is in the OFF position the power supply to the flashing light is continuous. Therefore the terminals
must be connected to a low voltage flashing light with a built-in oscillating circuit (type FEBOLIX 12VDC 2W).
If the dip-switch 5 is in the ON position the power supply is intermittent and therefore a normal lamp without
oscillating circuit can be connected (12VDC, Max 10W). During the closing manoeuvre, the flashing frequency is
twice as fast as that during opening.
The flashing light is only activated during movement. If AC mains power supply is missing and the unit
works under battery power supply, the flashing light will only flash for the first 4 seconds of the manoeuvre.
5.9

GATE OPEN WARNING LIGHT

If the safety device self-test is not used (DIP 8 "PHTEST" is OFF), the output +TX (terminal 10) acts as a
GATE OPEN WARNING LIGHT. Connect a 12V lamp (max. 3W) to terminals 10 ("+TX") and 9 ("COMMON") of
the control unit. The status of the lamp is as follows:
- If the access is closed the light is switched off
- If the access is open or opening the lamp is alight with a fixed light
- If the access is closing the lamp flashes

5.10 SLOW-DOWN

The slow-down function allows the gate to apply a reduced force before reaching the limit stop. The speed is
reduced to about one third of the normal working speed.
The slow-down function can be enabled or not during the Professional Learning procedure. With this control unit
the slow-down start can be selected independently for the two leaves, both in opening and closing.

5.11 ELECTRIC LOCK

Using the ELU expansion card an electric lock can be managed. The contact given by the ELU card is clean
and allows the managing of electric locks of 12 or 24 Volt max.15W according to the output voltage of the
