Trimmer "FOR" - Motor speed
Use the "FOR" trimmer to adjust the voltage with which the motor is powered during operation, thus adjusting its speed. This is
settable between 50% and 100% of the maximum force and can be increased by turning the trimmer clockwise.
Thus if the trimmer is set on the minimum then the speed is equal to about 50%, if adjusted in an intermediate position it is equal
to 75%, while at the maximum the speed will be the largest obtainable.
A variation of the "FOR" trimmer requires the repetition of the learning procedure since the operation times, and
!
thus the moments in which to start the slow-down, vary.
Trimmer "PAU" - Pause time
The "PAU" trimmer is used to set the pause time of the control unit if the automatic closing is enabled by means of DIP 3.
The pause time is settable between 3 and 60 seconds and can be increased by turning the trimmer clockwise.
Thus if the trimmer is set at the minimum then the pause time is equal to about 3 seconds, if adjusted to an intermediate position
it is equal to about 28 seconds, while at the maximum the pause time will be about 60 seconds.
Trimmer "OBS" - Obstacle sensitivity
The "OBS" trimmer is used to adjust both the intervention delay after detection of an obstruction and the opposing force to be
used by the automation. This function is useful to overcome any critical points of the automation where, for a brief time interval,
there is greater power absorption by the motor.
Both the intervention delay and the opposing force can be increased by turning the trimmer clockwise. The intervention delay
can be set between 0.1 and 3 seconds.
Thus if the trimmer is set at the minimum then the intervention time is equal to about 0.1 seconds, if adjusted to an intermediate
position it is equal to about 1.5 seconds, while at the maximum the intervention time will be about 3 seconds.
OPERATION OF THE SAFETY DEVICES
PHOTOCELL (PHO input)
When triggered, the photocell provokes:
- in closing phase, an inversion of the motion, either immediate or when cleared, according to the programming,
- in opening phase it has no effect,
- when the access is closed it has no effect on the opening commands if set for immediate inversion, otherwise it delays the
opening until it is cleared,
- if the access is open it inhibits the closing commands.
SAFETY IN OPENING (SFT/PED input)
Safety devices can be connected (self-testing or not) to the "SFT" input on the control unit (e.g. fixed wire ribs,
pneumatically-operated ribs, etc.).
The safety acts as follows:
- in closing phase it has no effect
- in opening phase it provokes an inversion of direction for 2 seconds,
- when the gate is closed the opening commands are inhibited,
- when the gate is open the closing commands are inhibited
SAFETIES SELF-TEST
The control unit has a self-test function of the safeties connected to the "PHO" and "SFT" input.
It switches off the transmitter to check the commutation of the corresponding receiver contact before the execution of each
manoeuvre. In this case, the "gate open warning light" is not available.
To activate this self-test function proceed as follows:
- switch DIP1 to ON
- connect the positive of the photocell transmitter power to the terminal "+TX"
If the enabling of the safety self-test is not required switch DIP1 to OFF.
