ACHIEVEMENTS
Any deficiency in the washing process is
apparent when dirty residuals are visible.
Any halos might be caused by an
insufficuent rinsing: in this case, check
that the rinsing jets are clean and there is
a sufficient pressure in the water
distribution network (2÷4 bar) ;
In the case that residuals are present,
check that:
• the washing jets are clean
• pre-washing temperatur is 40 °C
maximum;
• washing temperature is from 55 to 60 °C,
• rinsing temperature is from 80 to 85 °C,
• there is detergent in the right
concentration;
• the filters are clean;
• washing water is not dirty;
• the positions of the objects on the
conveyort belt are correct.
SAFETY DEVICES
The belt conveyor dishwashers are
equipped with a number of devices in order
to ensure the safety of the operator and of
the appliance itself.
LIMIT MICROSWITCH
If dishes reach the end of the unloading
area, before the operator has managed to
unload the dishes, the limit switch stops
the belt conveyor motion.
DOOR MICROSWITCHES
Each inspection door is provided with two
safety microswitches forming two
redundant chains (safety level 2).
If one of the doors accidentally opens, the
pumps, the conveyor belt gearmotor and
the rinsing area solenoid valve stop
working.
This way all washing operations are
stopped preventing dangerous jets of hot
water from spurting out.
The operation is restored only when the
doors are closed again and the start button
“H” pressed.
EMERGENCY STOP PUSHBUTTON
Dish inlet and outlet side of the machine is
equipped with a red mushroom-head
pushbutton on yellow field, which, if
pressed, stops all motors. Once the trouble
has been removed, it is possible to restart
the machine only after the pushbutton has
been rotated and released. Subsequently
press the start button “H” again.
TORQUE LIMITER
The belt forwarding feed system is
equipped with a mechanical clutch
coupling joint placed on the feed system.
When an object incorrectly interposes
between the machine and the belt, or the
belt itself is overloaded, the forward
feeding quickly moves to zero.
In this case it is necessary to switch the
machine off by means of stop or
emergency pushbuttons, remove the
obstacle and press the start pushbutton
again.
In order to adjust this safety device, see
paragraph "MAINTENANCE”.
