1.1 COROBTM D300 parts
COROBTM D300 is an automatic dispensing machine available with sixteen colourant canisters. The
canister size is four or six litres. COROBTM D300 is meant for dispensing water-based colourants
and its main operational utilisation is for all kinds of shops and other institutions.
NOTE!: Optional equipment is indicated by a dashed line.

6 1 - General
COROBTM D300
The COROBTM D300 has three interface boards: A, B and C. The boards A and B are for controlling
solenoids. The solenoid board A that controls the valves is in front of the dispensing module, in the
lower part of it, see number 8 in figure 5. The other solenoid board, board B, is in the solenoid rail
assy behind the dispensing module, see figure 9. The pump or the pumps that are going to
dispense are selected with this board.
Movement of the impellers of the colorant canisters are controlled with the interface board C.
There is a stirring motor under each colorant canister. This motor rotates the impeller inside the
canister. The interface board C is on the right side of the canister rack, it’s marked with letter C in
figure 3 on page 3.
The locations of the sensor boards are marked in figure 71 on page 32. The cable interface is on
top of the can table, see number 10 in figure 5 on page 4.
Solenoids
The COROBTM D300 has 33 solenoids, two different sizes:
• sixteen smaller ones for selecting the piston of the pump. These solenoids are behind the
dispensing module. The wiring order to solenoids from the board is described in figure 10.
• sixteen bigger solenoids are for opening the valves. The solenoids are in front of the
dispensing module. The wiring order from the board to the solenoids is described in figure 11.
Figure 8: The wiring order to stirring
motors on the interface board C.
Figure 10: The wiring order on the
interface board B.
Figure 9: Interface board B is fastened to the
solenoid rail assy behind the dispensing
module.

which controls the movement of the valves.

• one solenoid controls opening and closing of the humidifier cap. This solenoid is beside the air
pump in the dispensing module, number six in figure 5.
Sensors
The sensors in the COROBTM D300 are used for
• monitoring if the humidifier cap is under the nozzles or not, (CUP)
• counting the pulses of the dispensing motor (PULSE),
• monitoring when the crank passes 0 point (ZERO) and
• monitoring if a paint can is on the table or not.
The sensor of the humidifier cap is attached to the nozzle assembly. The pulse and the zero
sensors are connected to the dispensing module assembly. The can sensor is on top of the can
table.
You can also see the location of the sensors in figure 71 on page 32 and in figure 72 on page 33.
