3.1) TRAVEL LIMITS:
Once you have reached this point of the installation you can now set the travel limits within which the gate/door can move. As
described in the introduction (Chapter 1.1), the gearmotor has a gate/door position control system that optically reads the shaft’s
rotation degrees, controlling it all the time.
Of course the internal logic has to be instructed as to the distances within which movement must occur; these distances are
shown in the diagram in Fig. 3 as well as a description of their meaning.
Fig. 3
“RO1024” SLIDING GATE
“CR2024” SECTIONAL DOOR
“CR2024” 2-WING SLIDING DOOR
“0”= Mechanical Stop in CLOSING (corresponding to item M)
“C”= Desired CLOSING point
“B”= Desired PARTIAL OPENING point
“A”= Desired OPENING point
“1”= Mechanical Stop in OPENING (corresponding to item M)
All these distances are stored in a permanent memory on the control card during the programming phase. It is also possible to
programme these distances “manually” one by one so you can make the gate/door stop in exactly the places you want. To
simplify the programming there is a completely automatic programming phase.
If the gearmotor has never been installed before there will be no valid distances memorised so normal gate/door movement will
be impossible; in this case the first command that reaches the inputs or if the “CLOSE” key is pressed, an “initial limits search”
procedure will be activated immediately.
Do not activate the “initial limits search” unless the necessary “Mechanical travel stops” have been installed!
3.2) INITIAL LIMITS SEARCH:
The “initial limits search” procedure is extremely easy, entailing only these two phases:
1)
Power the unit and make sure that all the safety devices are active and effective.
2)
It is advisable to power on the gearmotor and bring the gate 50-100 cm from the mechanical stop in closing and then
power off; in this way the “initial limits search” will be quicker.
3)
Briefly press the small “CLOSE” key on the control card.
