The motor will now move the gate/door slowly in the closing direction until point “0” is detected (mechanical stop that defines the
maximum closing point). Once point “0” is reached the gate/door stops, causing the intelligent clutch system to work (see Chapter
1.3) and the close mechanical stop point detected by the encoder will be used to reset the “distance counter”. Immediately after,
the gearmotor will move the gate/door slowly in the opening direction until point “1” is detected (the other mechanical stop that
defines the maximum opening point); when point “1” is reached, the gate/door stops and the distance is memorised.
The maximum travel limits have been measured with these two operations. With a mathematical operation point “C” is calculated
which is set, if used like RO1024 (with switch 10 in the OFF position) 5 centimetres from point “0”.
Point “A” is set a few centimetres before point “1” and, lastly, point “B” is set, in the case of CR2024, halfway between points “0”
and “1” while in the case of RO1024, 1 metre from point “C”.
Now all the distances are memorised and finally the gate/door will move quickly until it reaches point “C”.
4)
the “initial limits search” procedure is now completed. Set the function dip-switches in the mode required and the
gearmotor is ready to use
As the procedure described memorises the distances that have just been measured automatically, no other operations are
necessary.
If, during the “initial limits search”, an external event occurs (another small key is pressed, the Photocell triggers or there is a
Step-by-Step pulse) gate movement will be stopped immediately, and the operation must be repeated from point (3).
Subsequent to an initial search, if you wish to, you can modify any of the distances measured (except for distance 0) by means
of the manual search.
4.1) PROGRAMMING:
As an alternative to the “initial limits search” which only takes place if the gearmotor has never been installed before, it is possible,
at any time, to activate an “automatic limit search” or to directly establish each single position by manual programming.
The various phases and the specific parameter to programme are selected with two sets of Dip-Switches on the card which are
called, respectively, “FUNCTIONS” and “PROGR.”.
a
a
PROGR.: It activates the various possible programmes. In the normal functioning
mode the two dip-switches must be in the “OFF” position
FUNCTIONS: In “normal” use it is used to set the functioning modes required
In the programming phase it is used to select which parameter to memorise
In the gearmotor’s normal functioning mode the “PROG.” dip-switches must be turned “OFF” and the functioning modes can be
selected with the “FUNCTIONS” dip-switches. If one of the “PROG.” dip-switches is turned “ON” the programming phase is
entered and the “FUNCTIONS” dip-switches will be used to select the parameter to be memorised. If the programming phase is
active and an incorrect parameter is selected with the “FUNCTIONS” dip-switch, the “OK” LED will start flashing quickly.
4.2) MEMORISING THE PARAMETERS:
The manual parameter programming phases end when what has been selected has been memorised. You will find that the
“Memorising procedure” will be referred to several times in the following chapters, in these cases it is necessary to carry out the
following procedure:
Memorising Procedure
1)
Press the blue coloured “<<>>” key for at least 2 seconds
(the OK LED will flash quickly)
2)
Take your finger off the “<<>>” key
(the OK LED will flash quickly for 3 seconds -Whilst it is flashing proceed quickly to the next stage ...)
3)
Press the two small yellow keys “A” and “C” simultaneously for an instant
The OK LED will stay on for 2 seconds to confirm correct memorising.
At this point the parameter selected has been permanently memorised.
