Characteristics of power supply
The AC power supply to the machine must meet the following conditions:
• max. voltage variation ± 10%
• max. frequency variation ± 1% continuous ± 2% for a short period.
Harmonic distorsion, unbalanced three-phase supply voltage, voltage pulses, interruption, dips and the other electric
characteristics must respect the provisions of point 4.3.2 of Standard EN 60204-1 (IEC 60204-1).
IMPORTANT!
The machine’s power supply must be protected against overcurrents (short circuits and overloads) by fuses or suitable thermal magnetic circuit breakers.
These must be fitted on an omnipolar disconnection system having a contact gap of at least 3 mm.
IMPORTANT!
For protection against indirect contacts (depending on the type of supply provided for and connection of earths to the equipotential protection circuit) refer to point 6.3.3 of EN 60204-1 (IEC
60204-1) with the use of protection devices that ensure automatic cut-off of the supply in case of
isolation fault in the TN or TT systems or, for IT systems, the use of isolation controllers or differential current protection devices to activate automatic power disconnection (an isolation controller must be provided for indicating a possible first earth fault of a live part, unless a protection
device is supplied for switching off the power in case of a such a fault. This device must activate
an acoustic and/or visual signal which must continue for the entire duration of the fault).
For example: in a TT system, a differential switch with cut-in current (e.g. 30 mA) coordinated
with the earthing system of the building where the machine is located must be installed ahead of
the supply.
IMPORTANT!
Customers are requested to follow these instructions, otherwise the Manufacturer does not guarantee the machine for continuous operation and/or against faults.

IMPORTANT
The GUARANTEED RINSE SYSTEM (GRS) is incorporated in the ACTIVE/ WASH SAFE CONTROL models
(see led “P”). The GRS is an automatic rinse time/temperature control system.
Operation is as follows:
• during the wash cycle the indicator light is OFF;
• during the rinse cycle the indicator light comes on and is GREEN;
• at the end of the rinse cycle the indicator light remains GREEN if the rinse temperature and time have
been carried out as per the programme, otherwise the indicator light becomes RED;
• upon opening the hood, the indicator light GOES OUT.
If the indicator light becomes RED, for example should the boiler waiting time be disabled, wait for a couple of minutes and then repeat the wash cycle.
The temperature shown on the display is that of the tank if the light “D” is on, or of the boiler if the indicator light
“F” is on. The tank temperature is displayed during the wash cycle and the boiler temperature during the rinse
cycle.
In automatic versions the machine has a LED bar "Q" which monitors equipment status. When the LED bar is
green the machine is ready for washing and when it is blue it indicates wash cycle progress status. After rinsing,
the LED bar remains green if the temperature and rinse time were as programmed, otherwise the LED bar turns
RED.

IMPORTANT
The mixing of different types of detergent/rinse-aid
will cause crystallisation, which may result in a
breakdown of the dosing pump. Failure to observe
this condition will invalidate the guarantee and
product liability.
Listed below are special values usable when external
automatic dispensers are connected to the equipment:
-
if the detergent dispenser only
operates during wash pump operation; terminals
7-9 of the main terminal board are powered at the
same time.
-
if the detergent dispenser only
operates during filling electrovalve operation for
restoring the boiler level; terminals 7-9 of the main
terminal board are powered at the same time.
-
if the rinse-aid dispenser only
operates during filling electrovalve operation for
restoring the boiler level; terminals 8-9 of the main
terminal board are powered at the same time.
if the rinse-aid dispenser only operates
during wash pump operation; terminals 8-9 of the
main terminal board are powered at the same time.
For connections, see the wiring diagram.
-
Example 1:
Supposing that an external detergent dispenser has
been connected with a tank concentration measuring
sensor, a standard setting could be as follows:
•
•
•
the parameter value is in seconds.
the dispenser is not activated during filling of the tank.
the dispenser is activated during
wash pump operation and, according to the concentration of detergent detected by the sensor, the
correct amount of detergent is dispensed.
Example 2:
Supposing that an external rinse-aid dispenser has
been connected with a tank concentration measuring
sensor, a standard setting could be as follows:
•
•
the parameter value is in seconds.
the dispenser is activated at each wash
cycle simultaneously with operation of the filling
solenoid valve. In this way avoiding modifications to
the wiring of the machine.
Suggestion: to check the effectiveness of the rinseaid, look at freshly washed glasses against the light.
Drops of water remaining on the glass indicate an
insufficient amount while streaks indicate an excess.
Changing the detergent/rinse-aid type.
If changing to a different detergent/rinse-aid type
(even one by the same manufacturer), you must rinse
the suction and pressure hoses with fresh water before
connecting the new detergent/rinse-aid container.

Hood type dishwasher with incorporated
continuous water softener
These models have a continuous softener in the
dishwasher water circuit. By means of special resins,
this device removes the calcareous substances from
the feed water, supplying decalcified water for
washing.
For the continuous softener to work properly the resins
must be regenerated periodically, with frequency
depending on the hardness of the water and the number of wash cycles carried out.
Unlike conventional water softeners, this continuous
softener does not require machine stops for regenerating the resins.
