Guide for the installer
3.3. INSTALLING THE RACK
1. Prepare the rack (supplied on request), with the supplied Hex-head
M8 x 25 screws, and spacers to be welded, as shown in Fig. 9. To
avoid having to weld on the gate, galvanised through-spacers
and Hex-head M8 x 50 securing screws are available.
We advise you to tighten the securing screws of the rack on
the top end of the slot. This position will enable you to raise
the rack when the gate tends to lower through time.
2. Release the operator (see paragraph 7).
3. Manually move the leaf to its open position.
4. Lay the first element of the rack on the pinion, on the first spacer
(fig. 10).
5. Secure the rack element to the leaf with a clamp (fig. 10).
6. Manually slide the leaf toward the closing point until you reach
the rack's third spacer, and fix it with a weld spot.
7. Definitively weld the three spacers on the gate. Procedure for
correctly fixing the other rack elements required to reach the
closing position:
a– Bring near another rack element to the last fixed element, using
a piece of rack to synchronise the teeth with the two elements
(fig. 11).
b– Manually slide the leaf toward the closing point until you reach the
pinion with the third spacer of the element to be secured (fig. 11).
Looking at the motor from above, check if all elements of the
rack are working in the centre of the pinion teeth. If this is not
the case, you need to adapt the gearmotor position.
c– Weld the element's three spacers (fig. 10).
a) Do not, on any account, weld the rack elements either to
the spacers or to each other.
b) Do not, on any account, use grease or other lubricants
between rack and pinion.
d– To obtain correct play between rack and pinion, lower the ge-
armotor by 1.5 mm, using the nuts supporting the foundation
plate. When you have finished adjusting, correctly tighten the
operator securing nuts.
If the gate was recently built, check this play (fig.12) a few
months after installation.
e– Manually check if the gate is free to open completely and if leaf
movement is good and friction- free
3.4. POSITIONING THE STROKE-LIMIT MAGNETS
The operator has a magnetic limit-switch, which commands gate mo-
tion to stop when the magnet, which is secured to the upper part of the
rack, activates the sensor. The magnets supplied with the operator are
specifically polarised and activate only one of the sensor's contacts:
the closing or opening contact. The magnet activating the open gate
contact bears an open padlock symbol, and, vice versa, the magnet
activating the closed gate contact bears the closed padlock symbol.
For the correct operation of the control unit, the magnet with open
padlock must be positioned near the gate opening edge, vice versa
the magnet with closed padlock must be positioned near the gate
closing edge, see figures 13 and 14.
Procedure for a correct positioning of the two stroke-limit magnets:
1. Assemble the two magnets as shown in figure 13 or 14.
2. Set the operator to manual mode operation - see paragraph
7 - and power up the system.
3. Manually take the gate to opening position, leaving about 40 mm
from the opening mechanical stop.
4. Slide on the rack the magnet with the open padlock in the opening
direction, until it is detected (see Figure 15). Then slide the magnet
10 mm forward and secure it temporarily with appropriate screws.
5. Repeat the operations from point 3 for the closing magnet.
6. Re-lock the system (see paragraph 7).
Before sending a pulse, make sure that the gate cannot be
moved manually.
7. Command a complete gate cycle to check if the limit-switches
are operating correctly
- To avoid damaging the operator and/or interrupting opera-
tion of the automated system, leave a distance of about 40
mm from the safety mechanical stops.
- Make sure that at the end of both the opening and closing
manoeuvre, the relevant contact stays active.
8. Change the position of the magnets as necessary and secure
them definitively.
4. ELECTRICAL CONNECTIONS
Connect the grounding cable of the power line to the screw securing
the board support, as shown in fig. 16.
5. START-UP
1. Program the control unit according to your needs, as per relevant
instructions.
2. Power up the system.
3. When you have run the automated system test (par.6), secure the
protective housing on the operator, using the supplied screws as
shown in fig. 17.
6. AUTOMATED SYSTEM TEST
Check operating efficiency of the automated system and all acces-
sories connected to it.
Hand the customer the "User's Guide" page and explain how the
automated system operates correctly and how it should be used.
7. MANUAL MODE OPERATION
If the gate has to be moved manually due to a power cut or fault of
the automated system, use the release device as follows:
• Cut power to the system.
• Using a coin, turn the lock clockwise until it stops (Fig. 18 ref.
• Pull the lever as shown in fig. 18 ref.
• Move the gate by hand.
Procedure for restoring normal operation:
• Cut power to the system.
• Position the gate at about halfway of opening travel.
• Take the release lever back into its position;
• Using a coin, turn the lock anti-clockwise until it stops;
• Restore power to the system.
When power is restored, command another complete ope-
ning cycle.
Before sending a pulse, make sure that the gate cannot be
moved manually.
8. SPECIAL APPLICATIONS
Applications other than those in this manual are EXPRESSLY PROHIBITED.
9. MAINTENANCE
To ensure correct long-term operation and a constant level of safety,
we advise you to generally check the system every 6 months. In the
"User's Guide" booklet, there is a form for recording jobs.
10. REPAIRS
The User must not in any way attempt to repair or to take direct action
and must solely contact qualified personnel.
