The automated system is supplied with travel limit devi-
ces already prepared for a left hand installation of the
beam.
To adjust the cam position, operate as follows:
1.
Manually move the rod into closing position.
2.
Turn the cam,
fi
g. 22 ref.
, until the travel limit device engages.
3.
Slightly advance the cam.
The travel limit device must operate before the mechanical
stop.
4.
Block the cam position tightening the relevant screw.
5.
Move the rod into opening position.
6.
Turn the cam,
fi
g. 22 ref.
, until the travel limit device engages.
7.
Slightly advance the cam.
The travel limit device must operate before the mechanical
stop.
8.
Block the cam position tightening the relevant screw.
In the event of right hand installations, reverse the wires
of the travel limit devices connected to the unit, see
control board instructions.
9.
Block the automated system again as indicated in paragraph 8.
4. INSTALLING THE ACCESSORIES (Optional)
Holes have been prepared on the upright of the automated system
to facilitate fastening operations for accessories (if any), such as
photocells (Orion) and key-selector (Quick).
Fig. 23 shows the accessories that can be
fi
tted on the housing
of the automated system.
On the upright sides as well as over the entire beam length you
can install signalling lights.
To
fi
x the single accessories, please refer to the relevant instruc-
tions.
5. ELECTRIC CONNECTIONS
Install an omnipolar switch on the power supply mains of
the automated system with contact opening distance
of 3 mm or more. The use of a thermal magnetic switch
6A with omnipolar switching is recommended.
Make sure that a differential switch with 0.03 A threshold
is
fi
tted upstream of the system.
At the end of the assembling and adjusting operations of the
mechanical part of the automated system you can connect the
power mains and all accessories
fi
tted.
To connect the power cable you need to open the prepared hole
on the central box,
fi
g. 24 ref.
, and mount the supplied cable
gland M16x1.5.
A channel for the cable routing has been prepared inside
the upright.
The power cable must enter the control unit passing through
its dedicated cable gland.
To connect the power line and the accessory line to the
control unit, please refer to the instructions for the control
unit.
The control unit has been located on a swinging support,
fi
g.
25. This makes the wiring and programming operations for the
control unit easier.
6. START-UP
• Place the panel as shown in
fi
g. 26 and power up the system.
• Check the status of the signalling LEDs and of the control unit.
• Perform the programming procedure for the control unit accor-
ding to your needs.
• Perform a functional check of all the accessories connected,
paying special attention to the safety devices.
• Close the unit enclosure and position it horizontally.
• Place the upper cover as shown in
fi
g. 27.
• Inform the end user about the correct operation of the automated
system
• Show the release and lock operations of the automated system.
• Hand over the booklet “User’s guide”: this is a detachable booklet
in the middle of the manual. Fill out the enclosed maintenance
register.
7. MANUAL OPERATION
If a manual operation of the rod is necessary due to a fault of the
automated system or to a power cut, operate as follows:
Cut power to the system using the differential switch
upstream of the system.
• Insert the key into the release device and turn it clockwise until
it stops, as shown in
fi
g. 28 ref.
.
• Turn the release device clockwise until it stops,
fi
g. 28 ref.
.
• Move the rod by hand,
fi
g. 28 ref.
.
8. RESTORING NORMAL OPERATION
To prevent an involuntary pulse from activating the au-
tomated system, make sure the system is not powered
up using the differential switch, before restoring normal
operation mode.
• Turn the release device counter-clockwise until it stops, Fig.
29 ref.
.
• Turn the key counter-clockwise until it stops and then remove
it,
fi
g. 29 ref
.
• Move the rod by hand until it stops,
fi
g. 29 ref.
.
• Power up the system again.
9. MAINTENANCE
To ensure a correct operation and a constant safety level over time
perform, every six months, a general check of the system paying
special attention to the safety devices. The booklet “User’s guide”
contains a form for the registration of the maintenance operations.
Every maintenance job or inspection performed by the
operator must only occur after having cut power to the
system and with the rod in vertical position.
For the correct operation of the barrier, we recommend you to
periodically replace the spring and the balancing springs. The table
below shows the spring life according to the type of automated
system and spring used:
Spring type
RAINBOW
324 C
RAINBOW
524 C
RAINBOW
724 C
Strong spring 500.000 cycles 500.000 cycles 200.000 cycles
Soft spring
500.000 cycles 500.000 cycles 350.000 cycles
In applications with a double spring also replace the tie rod
adjustment Fig. 20 ref
.
To remove the spring or the balancing spring in complete safety,
operate as follows:
1.
Cut power to the system.
2.
Prepare the operator for manual operation; move the rod into
vertical position and lock the operator again making sure that
it cannot be moved manually.
3.
Remove the upper cover and the panel.
4.
Now you can remove the balancing springs.
If you need to remove the rod for maintenance operations, you
need to perform the following:
1.
Remove the balancing springs as described before.
2.
Prepare the operator for manual operation and move the rod
into horizontal position.
