Limit Switch Adjustment; Final Operations - tau CITY/O Serie Manual De Uso

The barrier is normally supplied with the limit switches already
adjusted for the ideal movement of the bar.
In the event that the foundation plate is incorrectly positioned, the
bar may not be perfectly horizontal or vertical thereby giving the
barrier an unpleasant appearance.
The course of the bar can be modified to rectify this problem by
moving the vibration-damping plugs of the mechanical stop back or
forward (1 fig. 8), by means of the lock nuts (2 fig. 8) of the plugs.
Note: the memorisation procedure on the control unit must
be repeated each time the position of the mechanical stops is
modified (see K205M instructions).
Once the adjustment has been made, turn the power back
on and perform the memorisation procedure on the control
unit (see K205M instructions), and check the correct position
of the bar from the second automatic manoeuvre (the first
manoeuvre is for the control unit to acquire the new stops), if
the position is incorrect repeat the procedure.
Having tested the efficiency of each individual device concerning
the command and control of the barrier, ensure the integrity of the
barrier before handing over to the end user.
Place notices indicating the presence of an automatic barrier in an
easily legible location.
The barrier has been exclusively designed to limit the flow of
vehicles and/or persons in restricted entrances by means of a
bar. In the event of blackout, functioning can be guaranteed by
means of an optional 12V dry battery having an autonomy of
approximately 10 manoeuvres.
Furthermore, it also comprises electrical equipment and therefore
must be approached and used with caution and foresight. In
particular we recommend:
• not to touch the equipment with wet hands and/or bare or wet
feet;
• not to perform the automatic or semiautomatic function in the
presence of known or suspected malfunctions;
• not to pull the cable to disconnect the equipment;
• not to let children, or those unable, use the cabinet keys or
controls (including remote controls) even if only to play with;
• not to operate the barrier until it is completely in view;
• not to enter within the operating range while it is moving, wait
for it to stop;
• not to rest against the bar or cabinet for any reason, even when
the barrier is inactive and do not remain within the operating
range of the barrier;
• not to let children or animal play within the operating range of
the barrier;
• not to use the barrier for purposes (e.g. lifting of weights or
persons) other than those foreseen. The manufacture holds no
responsibility what so ever for damages caused by the said
actions;
• to perform periodic maintenance by specialised personnel;
• if there is a fault, turn off the power supply. Use the manual
manoeuvre only if safe. Do not attempt to resolve the problem
yourself, contact a qualified technician of the manufacturer or
authorised by the manufacturer. In any case, make sure that
the spare parts are original so that the safety of the barrier is
not compromised.

To be performed by specialised personnel only after having turned
off the power supply.
After every 100,000 manoeuvres, check:
- the greasing of the spring;
- the balance of the bar (see chapter "SECURING OF BAR AND
BALANCING");
- the efficiency of the force;
- the integrity of the battery;
- The efficiency of the protection and safety devices;
- the wear on the mechanical stops and the adjustment of the
limit switches (see chapter "LIMIT SWITCH ADJUSTMENT").
The above mentioned maintenance is vital in order that the
product functions correctly throughout time.
In general
It must be impossible for third parties to operate the barrier during
maintenance; therefore turn off the mains power supply (and
battery if present).
• Release the bar first in order to facilitate the operation.
USE
Greasing
1_ open the cabinet door;
2_ grease the eyelets of the balancing spring (1 fig. 11);
3_ grease the contact points between the cam of the manual
release and the release lever (2 fig. 11);
4_ keep away from possible moving gears or mechanical parts.
FREQUENCY: every 100,000 manoeuvres or 6 months, failing
which the guarantee lapses.
Bar balancing
Check the balance of the bar, repeating the manoeuvres
described in chapter "Securing of bar and balancing". This
operation is fundamental for the correct functioning and duration
of the barrier. If necessary, increase the preloading of the spring in
order to compensate for its wear. See the subsequent paragraph
"Extraordinary maintenance and repairs" in the event the spring
needs to be changed.
FREQUENCY: every 100.000 manoeuvres or 6 months, failing
which the guarantee lapses.
Control of the force limitation efficiency
Check the correspondence between the true operation and the
operation established during installation.
FREQUENCY: every 100.000 manoeuvres or 6 months, failing
which the guarantee lapses.
Control of the 12V dc battery
Check the charge level of the battery by means of a tester. If
replacement is necessary, substitute the flat battery with an
original and do not dispose of it in the environment.
FREQUENCY: every 100.000 manoeuvres or 6 months, failing
which the guarantee lapses.
Control of the remaining protection and safety devices
Photocells: they can trigger both in opening as well as in closing;
check the dip-switch programming. Clean the outer casing.
Check that the following specifications are respected:
• The flashing light is working and visible;
• The adhesive danger sign on the door is well attached and
visible;
• The adhesive danger sign on the back of the barrier is well
attached and visible. If these signs do not correspond to the
stated conditions, restore their original effectiveness or, if this
is impossible, replace them.
FREQUENCY: every 6 months, failing which the guarantee
lapses.
