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.
m
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 S.p.A. for repair.
Error 2
When a Start command is given and the gate does not open and
the following writing appears on display:
It means that triac test failed.
Before sending the control unit to V2 S.p.A. for repair, be sure
that motors have been properly connected.
Error 3
When a Start command is given and the gate does not open and
the following writing appears on display:
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.
Error 4
When a Start command is given and the gate does not open (or
does a partial opening) and the following writing appears on
display:
This means there is a problem with the limit switch.
Check the direction of the magnets, if they are backwards, they
should be removed and inverted.
If the magnets are installed correctly, it means that the limit
switch sensor is damaged or the cabling connecting the sensor
to the central control unit is broken/damaged.
Change the end of stroke sensor or the broken wiring.
If the error persists send the control unit to V2 S.p.A. for repair.
Error 5
Once given a start control, the gate does not open and the
display shows:
It means that the test of the safety edges failed. Make sure that
the control unit driving the safety edges is correctly connected
and properly working. Make sure that the safety edges enabled
by menu are actually installed.
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.
