5.12.5 Underwalk protection
(R

)
To comply with European Standard EN 1501-5 all
automatic and semi-automatic bin lift systems are
equipped with RPD.
This safety equipment protects persons approaching
the bin lift when it is emptying automatically (or semi-
automatically).
This safety equipment consists of two ultrasonic sen-
sors, fitted to the two 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 the safety arms are folded down.
•
As soon as the area under a lifted bin is entered,
during automatic or semi-automatic lifting, the
downward movement is stopped.
- A warning light mounted on top of each safety
arm comes on and indicates that the RPD has
been activated on this side of the bin lift.
- Automatic (or semi-automatic) lifting does
however remain active, the green light flashes.
•
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 automatical-
ly (or semi-automatically), the green light shows
a steady light again.
The sensors are checked during each automatic lif-
ting operation. When a sensor fault is identified the
automatic lifting is switched off.
•
The RPD system is designed such that it is not acti-
vated 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 warning light on top of the arm will flash.
This flashing indicates that the “unobstructed
view” of the sensor is blocked, or that there is a
fault in the RPD system.
- The bin lift still works manually, even with a fault
in the RPD.
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-automa-
tic 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.
Protected
area
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.
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!
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.
