Safety - Nederman AEB Manual De Instrucciones

GB

Safety

This manual presupposes that the automatic emptying
bin is installed on a FlexFilter or FlexPAK dust collector
and that emptying is regulated by a controller connec-
ted for 24 V DC. CE-marking
The manual is a supplementary manual to the dust
collector's or the FlexPAK 800/000 manual with AEB
and only the automatic emptying function is discussed.
Automatic emptying involves a risk of crush injuries
between moving parts. The factory mounted yellow-
black warning decals must always be in place on this
equipment.
The rubber cloth that surrounds the hatch must not be
removed.
Unauthorised personnel must not remain as close to
the dust collector that a risk for contact with moving
parts occurs. Emptying is usually time controlled and
fully automatic. Emptying can also take place when the
vacuum installation is stationary. If the vacuum unit's
starter equipment is a Nederman High Vacuum Starter
you can control emptying so that it is only operational
when the unit is in use, see "Supply and setting of
AEB".
The compressed air supply must be disconnected and
the emergency stop pressed in before servicing. Then
all compressed air components are purged.
On account of the remote controlled and automatic
function, the position of the emergency stop and func-
tion must be known to personnel that use or can come
into contact with the equipment. See fig. 2, pos. 5.

On delivery the emergency stop is placed on one side,
but there is an assembly hole even on the other side,
see fig. on the front page. It may be necessary to move
the emergency stop depending on the assembly site. It
should be positioned on the side where it is fully visible
and easily accessible.
The compressed air cylinder on the AEB has two
throttle valves that ensure the hatch opens and clo-
ses slowly. See fig. 3, pos. 7. These valves must not
be adjusted so that the movement of the hatch is
too quick as a greater movement speed involves an
increase risk of crush injuries.
If the collected material is heavy, for example, metal
chips and the quantity of material significant, the hatch
may be opened with considerable force by the com-
pressed air. The interval between emptying should be
short, to avoid an increase risk of crush injuries, if the
material is heavy.
Emptying to an open container or to a conveyor belt,
"open emptying", works best with material that does
not spread too much dust when emptying. (Closed col-
lection is recommended for light and dusty material.)
Open emptying, if it causes the spread of dust, should
not be used for health-impairing dust. It is the respon-
sibility of the customer to know what kind of dust is
sucked into the installation and draw up any procedu-
res and restrictions.
Open emptying shall not be used for dust that can give
rise to dust explosions. Emptying can produce large
quantities of airborne dust, in particular if the height of
fall is large, and result in static electricity forming with
an increase risk of dust explosion.
