External dispenser adjustment
With external dispensers, it may be more useful to
have the parameters expressed in seconds, setting the
parameter dun to SEC=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:
dEt=181
- if the detergent dispenser only operates
during wash pump operation; terminals 7-9 of the
main terminal board are powered at the same time.
dEt=182
- 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.
rAi=61
- 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.
rAi=62
- 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:
dun=SEC
• the parameter value is in seconds.
dIn=0
• the dispenser is not activated during filling of
the tank.
dEt=181
• 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:
dun=SEC
• the parameter value is in seconds.
rAi=61
• 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 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
product liability.
