OPERATING AND MAINTENANCE INSTRUCTIONS MINICOLOR

Operation
MINICOLOR
− Switch on On/Off switch (3, Fig. 5-4)
switch lights up
calibration measurement starts
LED "Motor" (4) lights up
− Switch off On/Off switch at the end of the
calibration time (5 minutes)
switch goes out
dosing screw stops
LED "Motor" (4) goes out
− Weigh calibration quantity in the measuring
bucket
measured calibration quantity
= 170 g in 5 minutes
− Put MINICOLOR in production position
(Fig. 5-7)

3. Calculating the motor speed
Calculating the motor speed W Prod.
W Prod. = Motor speed for production
M SET = Dosing throughput of dosing station
in kg/h preset nominal value of
production
(additive component)
M ACTUAL = Measured calibration quantity in g
t cal. = Actual calibration time in minutes
W Calib = Motor speed for the first calibration
M SET x 1000 x t cal x W Calib
= W Prod
60 x M ACTUAL
Formula 1
Example: i = 30:1
− Calculate the motor speed with formula 1
− Enter 116 in the decade switch (1, Fig. 5-4)
2,16 x 1000 x 5 x 110
60 x 170
= 116
Example
5.1.4 Production with injection moulding machines
− Put dosing station in production position, Fig. 5-7
− Put the control unit to production mode, i.e. put the selector switch (2, Fig. 5-4) to "Prod"
the dosing station operates for so long as an external contact from the injection moulding machine is on
