External dispenser adjustment
With external dispensers, it may be more useful to have
the parameters expressed in seconds, setting the
parameter to =seconds. In this way the value
of the parameters represents the duration in seconds.
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 sole-
noid valve. In this way avoiding modifications to the
wiring of the machine.
Suggestion: to check the effectiveness of the rinse-aid,
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.
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 prod-
uct liability.
