OBSTACLE SENSOR
The PD18 control unit has two independent systems allowing
detection of whether gate movement is impeded by obstacles.
The first system is based on measurement of the current
absorbed by the motor, and is available on all control units: an
unexpected increase in current absorption indicates the presence
of an obstacle. The second system is based on measurement of
the rate of motor rotation and is only available if the encoder
option is present: a decreased rotation rate indicates the
presence of an obstacle.
PLEASE NOTE:
the amperometric sensor is disabled by default
and must be enabled by means of the
SenS
menu option; the
rate sensor is automatically enabled by enabling the encoder
option, and its sensitivity may be adjusted by means of the
S.EnC
menu option.
The detection of obstacles by means of the amperometric sensor
only occurs if the gate is moving at normal speed. If slowing
down has already started, the obstacle is not detected; this
situation is not hazardous since, during slow motion operation,
the motor pushes the obstacle with greatly reduced power.
Obstacle detection by means of the rate sensor is also conducted
during slowing down: the alarm threshold is automatically
lowered in order to allow movement at lower speed.
When a sensor trips, the gate is stopped and then sent in the
opposite direction for 3 seconds, in order to free the obstacle.
The subsequent Start command restarts movement in the
previous direction.
PLEASE NOTE:
if limit switches and slowing are disabled, when
the amperometric sensor trips, the control unit interrupts the
current opening or closing operation, without reversing the
direction of motion.
CONTROL UNIT
CONFIGURATION
The configuration menu
-PrG
consists in a list of configurable
items; the display shows the selected item; pushing the wheel
downwards the following item is selected, pushing the wheel
upwards the previous item is selected. Pressing the wheel the
current value of the selected item is displayed and it is
possible to change it, if necessary.
The last item of the menu (
FinE
) allows to store the changes
made and to revert to the normal working of the control unit.
In order not to loose the own configuration it is compulsory
exiting through this menu item.
WARNING: If no operations are required for more then a
minute, the control unit exits from the programming mode
without saving the given information and changes will be
lost.
Keeping the wheel pushed downwards the configuration menu
items are quickly scrolled down until displayed the item
FinE
.
Likewise, keeping the wheel pushed upwards the items are
quickly scrolled down backwards until reached the item
t.AP
.
Like this, the beginning or the end of the list can be reached
quickly.
There are the following three kinds of menu items:
• Function menu
• Time menu
• Value menu
Function menu setup
Function menus allow selecting a function from among a group
of available options. When you enter into a function menu, the
current active option will be viewed; pushing the programming
wheel upwards or downwards it is possible to scroll down the
available options. The displayed option is started up pressing
the wheel; after this, back to the configuration menu.
Time menu setup
Time menus allow setting a function duration. When you enter
into a time menu, the current setup value will be viewed; the
display mode depends on the current value:
• times being lower than one minute will be viewed as follows:
Every time the wheel is pressed upwards (UP) the set time
increases of half a second; every time it's pressed downwards
(DOWN) the time decreases of half a second.
• Times between 1 and 10 minutes will be viewed as follows:
Every time the wheel is pressed upwards (UP) the set time
increases of 5 seconds; every time it's pressed downwards
(DOWN) the time decreases of 5 seconds.
• Times being more than 10 minutes will be viewed as follows:
Every time the wheel is pressed upwards (UP) the set time
increases of half a minute; every time it's pressed downwards
(DOWN) the time decreases of half a minute.
Keeping the wheel upwards (UP) the time increases quickly,
until reached its maximum. Likewise, keeping the wheel
downwards (DOWN) the time decreases quickly, until reached
0.0”
In some circumstances, setting the value to 0 means that the
relevant function is disabled, in this case, ‘
no
’ will appear
instead of
0.0”
.
The displayed option is confirmed pressing the wheel (MENU);
after this, back to the configuration menu.
Value menu setup
Value menus are similar to time menus; however, the setup
value can be any number. Keeping the wheel pressed upwards
or downwards the value increases or decreases slowly.
In the following pages the procedure to configure all the
parameters of the control unit
PD18
is shown step by step
