OBSTACLE SENSOR OPERATION

Pd8 control unit is equipped with a sophisticated system that
allows detecting if there is any obstacle stopping the gate
motion. The sensitivity of this system can be adjusted through
the Sens menu: the higher is the setup value, the prompter will
be the control unit intervention if there is any obstacle. If you
set on 0, obstacle detection will be disabled.
WARNING: apart from any setup sensitivity value, this
system will detect an obstacle only if the gate is stopped;
therefore, no obstacle braking the gate without stopping it will
be detected. In addition, this system does not work when the
gate move at slowed down speed.
The control unit reaction in case an obstacle is detected
depends on the t.rAL menu setup and on the moment when
such obstacle is detected.
Slowing down disabled
The door motor on which an obstacle is detected will stop
pushing and, for a second fraction, it will be given the
command to go backwards, so not to keep its gears under
stress.
Slowing down enabled
Obstacle detection will be performed only if the gate move at a
normal speed. The gate will stop and it will be given the
command to go backwards for 3 seconds, to take out the
obstacle detected. The following Start command will let the
former gate motion start again. In case the slowing down
phase has already begun, no obstacle will be detected and this
kind of situation cannot be considered as dangerous since the
motor, when working according to its slowing down function, will
push the obstacle with a very low pressure.

OPERATION DEFECTS

This paragraph shows some possible operation defects, along
with their cause and applicable remedy.
MAINS led does not switch on
It means that there is no voltage on Pd8 control unit card.
1. Before acting on the control unit, disconnect through the
disconnecting switch on the power line and remove the
power supply terminal.
2. Be sure that there is no voltage break upstream the control
unit.
3. Check whether the fuse is burnt-out, if so replace it with
same value.
OVERLOAD led is on
It means that there is an overload on accessory power supply.
1. Remove the extractable part containing terminals 1 to 12.
OVERLOAD led will switch off.
2. Remove the overload cause.
3. Reinsert the terminal board extractable part and check that
this led is not on again.
Error 1
The following writing appears on display when you exit from
programming:
It means that changed data could not be stored.
This kind of defect has no remedy and the control unit must be
sent to V2 Elettronica for repair.
Error 2
The following writing appears on display when a Start
command is given and the gate does not open:
It means that triac test failed.
Before sending the control unit to V2 Elettronica for repair, be
sure that motors have been properly connected.
Error 3
The following writing appears on display when a Start
command is given and the gate does not open:
It means that the photocell test failed.
1. Be sure that no obstacle interrupted the photocell beam
when the Start command was given.
2. Be sure that photocells, as enabled by their relevant menus,
have been installed actually.
3. If you have photocells 2, be sure that Fot2 menu item is on
CF.CH.
4. Be sure that photocells are powered and working; when you
interrupt their beam, you should hear the relay tripping.
Too long pre-blinking
When a Start command is given and the blinker switches on
immediately but the gate is late in opening, it means that the
setup cycle count down expired and the control unit shows that
service is required.
