Positioning Definition of the type of sensor used to position the obstacle.
Limit Switches
(by default)
To be selected if the position of the obstacle is determined by
limit switch interrupters, enabling the extreme positions of the
obstacle to be detected (completely open or completely
closed).
Analog. Sensor To be selected if the position of the obstacle is determined by
an analogue sensor.
The analogue position sensor measures the distance
separating it from a spiral cam located on the shaft that
transmits the movement of the obstacle’s motor, which
means that the angular position of the obstacle is known at
all times. Also, see the “Min Sensor Max” parameter below.
Manual Switch This message is displayed if it is not possible to activate the
analogue sensor, as per one of these cases:
• The crank presence detector (only present on some
equipments) is engaged.
=> Remove the crank so that the motor may be engaged.
• If the equipment does not have a crank presence
detector, the circuit may have been cut.
=> bypass the corresponding connector blocks.
Activate Motor? Pushing the OK key within 5 seconds launches the analogue
sensor activation procedure (see below) and the movement
of the obstacle!
Search LSO… The obstacle opens to look
for its limit switch.
Search LSC… The obstacle closes to look
for its limit switch.
The obstacle is moving
during this phase!
Init. Passed This is displayed if the opening and closing limit switches
were detected.
The analogue sensor is then operational.
The message disappears after 5 seconds or if the OK key is
pushed.
IMPORTANT
: Save the values in MEM1 or MEM2
(“MEMORY” menu), then turn off the control board and turn
it back on again.
Adjust Sensor Activation failed because the analogue sensor was not
properly positioned => adjust it (closer or further away from
the cam) so the measurement is included in the working
range (= between the min. and the max. set in the “Min
Sensor Max” parameter below).
Value 0 Detect Activation failed because the analogue sensor returned a
measurement of zero.
As this value does not exist, check:
• the sensor’s wiring (in the sensor as well as on the control
board's connector blocks);
• whether is sensor is too close to the cam;
• whether the sensor is functioning: LED on the sensor is
illuminated and the value measured is displayed in the
“Min Sensor Max” parameter below.
