Maintenance - tau P2000 Series Use And Maintenance Manual

USE
It is expressly forbidden to use the device for any other
purposes or under any other circumstances other than those
mentioned. The electronic control unit (which must be fi tted with
an electric clutch) allows the following functions to be selected:
automatic : a command impulse opens and shuts the gate
semiautomatic : a command impulse opens or shuts the gate.
In the event of a power failure, the gate may be moved manually
by activating the "manual release" device. Mod. P2000BENC can
be powered by a buffer battery and is able to perform at least 15
complete cycles (open and close) on its own.
This is an electrically powered automatic device and should
therefore be used with care. In particular:
• do not touch with wet hands and/or wet or bare feet;
• disconnect the power supply before opening the control box
and/or the actuator;
• do not pull the plug out by its cable;
• do not touch the motor unless you are certain it is cool;
• only operate the gate when it is completely visible;
• do not approach the gate while it is moving;
• do not allow children or animals to play near the gate;
• do not allow children or disabled people to use the remote
control or other operating devices;
• carry out routine maintenance;
• in the case of a fault, disconnect the power supply and only
move the gate if it is possible and safe to do so. Do not touch
the gate and call in an authorised technician.

MAINTENANCE

The P2000/P2000BENC actuators need very little maintenance.
However, as the gate must be in good working order for them to
work properly, the operations required to keep it in perfect condition
are described below.
ATTENTION: no-one, except for the maintenance man, who
must be a specialised technician, must be able to use the
automatic system during maintenance.
Switch off the mains power supply to eliminate the risk of
electrocution. If the power supply must be left on for certain
operations, each control device should be checked or disabled
(remote controls, push button strips, etc.) except for the one used
by the maintenance man.
Routine maintenance
Each of the following operations must be carried out when
necessary and always every 6 months for domestic use (approx.
3000 work cycles) and every 2 months for intensive use such as
blocks of fl ats (always 3000 work cycles).
Gate:
- lubricate and grease the hinges of the gate.
Automation system:
- check the safety devices (photocells, pneumatic edge, etc.)
work according to the manufacturer's instructions;
- grease (with a greaser) the worm screw from underneath the
actuator (see fi g.12); TAU srl recommends using the complex
lithium soap grease produced by SYNECO.
- use a tester for lead-acid batteries to check whether the
battery is charged; if it needs replacing use an original battery
and recycle the fl at one in compliance with current legislation
(alternatively, TAU srl recommends using FIAMM batteries).
Extraordinary maintenance or breakage
If major work on electromechanical parts must be carried out, the
faulty component should be removed and repaired in the workshop
by the maker's or other authorised technicians.
N.B.: Keep all the documents concerning the system inside
or near the control unit.

ANNEX
SAFETY DISTANCES FOR AUTOMATIC GATES?
• The distance A (fi g.14) between the jamb and the upright next
to the gate must remain constant when the gate rotates. If this
varies, the distance must be ≥ 25 mm up the whole height of
the gate; if this is not the case, fi ll in the extra space for the total
height of the gate up to a maximum of 2.5 m.
• The distance B (fi g.14) between the fl oor and the leaf must
be ≥ 50 mm, if distance B varies due to sloping ground, the
fi tter must take steps to reduce the danger of people or objects
getting trapped.
• In a two-leaf gate, the distance C (fi g.15) between the two
closed leafs must be ≥ 2,5 cm; this space can be covered by
installing a pneumatic edge on the side of the leaf or fi tting a
deformable fl exible element in the free space. If this space is
smaller or absent, the two leafs must be closed in sequence so
as to leave a clearance D (fi g.15) of 50 cm.
SAFE INSTALLATION HINTS
Man present operation: an emergency stop device and a fl ashing
light is suffi cient
Automatic or semiautomatic operation: install a fl ashing light
and adjust motor torque as described below; if this is not possible,
fi t a pneumatic edge.
• fi t one photocell at both gate's sides thus limiting the gate's
operating range. If the leafs overlap due to a stop profi le they
must be put out of phase (distance D fi g.15).
For all operation types: If the leaf stops during the opening phase
at a distance (E fi g.15) of less than 40 cm with respect to a fi xed
obstacle (wall, pillar, etc.), a pneumatic edge must be fi tted to the
leaf or the fi xed part as follows:
1 - if the obstacle is higher than it is wide apply the edge (for the
whole length of the obstacle) at a height of between 40 and 60
cm from the ground;
2 - if the obstacle is wider than it is high and is lower than 60cm
apply the edge 5 cm from the upper edge of the obstacle.
CHARACTERISTICS, ADJUSTMENT AND INSTALLATION
OF SAFETY DEVICES
Photocells :
• These are fi tted at a height varying from 40 and 60 cm from the
ground at a max. distance of 10 cm calculated from the edge of
the open leaf and from the edge of the closed gate.
Sensitive safety edge
• In the simplest cases there must be Normally Closed (NC)
contacts;
• Minimum deformation must be at least 1 cm greater than the
stopping distance of the gate from when the device cut in
Torque limiting device
• This must be adjusted so that the gate stops in the presence
of a mechanical resistance of 150 N (about 15 Kg) measured
on its edge as long as the kinetic force of the leaf is not greater
than 10 J.
