1 Fit the two pipe brackets on the ends of the ex-
haust rail.
2 Position the two pipe brackets in the rail side ac-
cording to the measures in the picture. Carefully
fasten them with supplied screws and rhombic
nuts.
3 Adjust the measure X, until the compressed-air
hose has plenty of room when the suction trolley
is in its stop position.
See Figure 9.
• Fit the wire with wire-lock in the pipe bend at the
rear rail end.
See Figure 10.
• Hang up the compressed-air hose on the wire.
See Figure 11.
1 Fit the wire stretching device on the pipe bend at
the exit end of the rail.
2 Cut off excessive part of the wire. Loosely wind up
the wire on the wire stretching device.
See Figure 12.
1 Angle the two pipes to suitable positions with re-
gard to space. Horisontal is recommended.
2 Fasten the pipe bends with the M6 screw (item A).
3 Then drill a hole 6,5 mm (1/3 in) in diameter
through the pipe bracket holes (item B) and the
pipe and fasten the pipe with supplied M6 screws
and nuts.
4 Tension the wire.
NOTE!
Make sure not to deform the pipe bend.
See Figure 13.
1 Insert the compressed air hose spiral carrier into
the trolley valve bracket (item B).
2 Position the carrier in the suction trolley bracket,
outside and close to the suspension wire, so that a
centered compression of the compressed air hose
spiral is obtained. Tighten the screw (item A).
3 Connect the compressed air hose spiral to the T-
coupling.
4 Fasten the compressed air hose with stripes to the
carrier pin.
5 Mount the disconnection trigger (item C) in the
rail.
NOTE!
The trigger(s) can be positioned vertically
to get individual disconnection for each
trolley. The lowest positioned trigger must
be placed closest to the exit. The exact pos-
ition in the rail needs to be tested on site as
it depends on exiting speed and number of
trolleys etc.
Pneumatic Rail System, PRS
6 Check the operation of the disconnection valve.
If necessary the height position of the disconnec-
tion trigger can be adjusted.
See Figure
• Fit the filter close to the pipe bend at the rear rail
end. The filter is automatic (drains at feeding pres-
sure drop of 0 1 bar) and can optionally have a drain-
ing hose connected at the bottom.
4.6 Compressed air connection
See Figure
NOTE!
The pneumatic components must only be used
with filtered compressed air. Use water and
oil separator with automatic draining and air
filtration according to DIN ISO 8573-1, class
5/5/4.
1 Disconnect the nozzle kit.
2 Make sure that the existing compressed air pip-
ing is clean and connect compressed air, 6 – 8 bar
(87 – 116 psi), to the system with a flexible hose to
avoid problems if the rail is moving.
3 Adjust the manometer on the compressed air
pressure regulator to 1 bar (14,5 psi).
4 Reconnect the nozzle kit.
4.7 Exhaust hose
See Figure
It is important that the nozzle suspends freely (ap-
proximately 30 cm (1 ft)) from the floor when the
hose is in its raised position.
NOTE!
The nozzle must not drag on the floor when
disconnected. Adjust it with the balancer. See
Section 4.8
1 Connect the nozzle kit on the safety coupling.
2 When applicable, fit the hose holder. Then fit the
balancer cord to the metal elbow/hose holder.
3 Adjust height if needed.
4.7.1 Metal elbow
See Figure
• For rail mounting heights higher than 4 m (13 ft 1 in)
the hose position is adjusted by moving the balancer
cord stop the necessary length.
• For rail mounting heights lower than 4 m (13 ft 1 in)
the exhaust hose must be cut in the following way:
1 Separate the safety coupling.
2 Close the compressed air supply.
3 Cut off the necessary length of the lower exhaust
hose.
14.
NOTE!
The filter must be fitted in a vertical position.
