To comply with European Standard EN 1501-5, all
automatic and semi-automatic bin lift systems are
equipped with an underwalk protection (RPD).
This safety provision protects persons approaching
the bin lift when it is emptying automatically (or semi-
automatically).
This safety provision consists of two ultrasonic sen-
sors fitted in both safety arms. The sensors detect
persons or objects coming within the protected area
of the bin lift.
This occurs separately for each lifting
chair.
The underwalk protection (RPD) is therefore only
active when lifting automatically (or semi-automa-
tically) and with the safety arms in horizontal
position.
•
As soon as the area under a lifted bin is entered,
during automatic or semi-automatic lifting, the
downward movement is stopped.
- The
green 'automatic' light
in the button
control station
flashes rapidly
when the RPD on
that side of the bin lift is activated.
- However, the automatic (or semi-automatic)
loading setting will remain activated.
•
Lower the chair manually using the manual push-
buttons, the warning light goes out and the RPD is
reset.
- The bin lift is again ready to lift bins automatically
(or semi-automatically), the green light shows a
steady light again.
The sensors are checked during each automatic
lifting operation. When a sensor fault is identified the
automatic lifting is switched off.
•
The RPD system is designed such that it is not
activated by rain or snow. When refuse, snow or
another object block the ‘unobstructed view’ of a
sensor, the lifting chair will rise and then stop.
- The green 'automatic' light will go out.
- The Diagnostic System display will show the
message '
AREA PROTECTION SENSOR
FAULT
'.
This indicates that the 'unobstructed view' of
the sensor is being blocked, or that there is a
defect in the RPD system.
- The bin lift will still work in manual mode, even
with an RPD error.
Because the RPD sensors monitor both sides of the
bin lift separately, in case of a defect on one side the
other will still lift automatically.
Semi-automatic function 4-wheel containers
(optional)
When the bin lift is equipped with the semi-automatic
function 4-wheel containers, the activation of the
RPD on one of the two sides will result in the bin lift
stopping in the tipping position.
In case of damage to the safety equipment,
this must be repaired or replaced by original
parts immediately.
Repairs to the RPD may only be carried out by
qualified personnel.
Keep a minimum distance of 2.5 meter
between the bin lift and objects which are
located behind the bin lift system. This is to
avoid a dangerous situation in case that a
bin/container falls from the pick-up comb.
Do not use defrosting fluids for accumulated
snow or ice removal, this leaves a sticky layer
and snow accumulates even faster.
Follow the safety procedure and sweep
accumulated snow BY HAND!
