Notes for external dispensers:
-if
dEt=181 the detergent dispenser only oper-
ates during wash pump operation; terminals 7 and 9
of the main terminal box are powered at the same
time.
-if
dEt=182 the detergent dispenser only oper-
ates during filling electrovalve operation for restor-
ing the boiler level; terminals 7 and 9 of the main
terminal box are powered at the same time.
-if
rAi=61 the rinse-aid dispenser only operates
during filling electrovalve operation for restoring the
boiler level; terminals 8 and 9 of the main terminal
box are powered at the same time.
-if
rAi=62 the rinse-aid dispenser only operates
during wash pump operation; terminals 8 and 9 of
the main terminal box are powered at the same time.
For connections, see the wiring diagram.
Example:
Supposing that an external detergent dispenser has
been connected with a tank concentration measuring
sensor, a standard setting could be as follows:
dIn=0 the dispenser is not activated during filling of
the tank.
dEt=181 the dispenser is activated during wash
pump operation and, thanks to the concentration mea-
sured by the conduction sensor, the correct amount of
detergent is dispensed.
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 on glass indicate an excess
amount.
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. Other-
wise, the mixing of different types of detergent/rinse-aid
will cause crystallisation, which may result in a break-
down of the dosing pump. Failure to observe this condi-
tion will invalidate the warranty and product liability.
