Description
2.2
Theory of Operation
The 400 ml Dual Cartridge Applicator should be pressurized via a higher-ranking
controller, e.g. PLC, with max. 6 bar (87 PSI).
The pushers 9feed the product out of the cartridge and through the feedline to the
Compact Rotor Pump or HD Dispenser.
When connected to the main air supply directly, the pushers can be switched via the
hand lever valves to the forward position, “keep in position”or backward position at any
time.
The maximum feed rate of product depends on four factors:
1. Adjusted air pressure
2. Feed tube diameter
3. Feed tube length
4. Product viscosity
With one proximity switches (PS) per channel (component) 10/11 the position of the
pushers can be evaluated.
The PS provides the “empty” signal, dependent from its adjustment.
As soon as the “empty” signal appears, the higher-ranking controller has to stop the
dispensing and wait for the user confirmation, that
–the empty cartridge has been replaced by a filled one and
–the pushers has been switched to the forward position.
For the exchange of the cartridge, the retraction of the pushers must be performed
manually by switching the hand lever valves to the backward position, see section 5.1.
The cartridge applicator should be under pressure only during dispensing and purging.
Otherwise the applicator has to be depressurized to keep in position. The pushers
should not be retracted.

Environmental and Operating Conditions
–Avoid kinking of pressure hoses.
–Typically, the pressure hose should not be longer than 2 m.
–Do not use inflexible hoses, so that unnecessary loads on the fittings will be avoided.
–Keep all fittings tight.
–No direct sunlight; no UV light!

Start Requirements
Warning!
Operate the dispenser only with inserted dual cartridge! Danger of pinching!
Operate cartridge applicator when
–Cylinder is in basic position (backward) and
–Cartridge is inserted.
The factory settings of the pneumatic flow controls need no changing in the forward
movements.
Pressure Input Limit
Caution!
Pressure input limit is max. 6 bar (87 PSI). Make sure that the limit is kept.

Insert the Dual Cartridge and Connect the Adapter
F Type Cartridge
Switch hand lever valve 7to the position
„Piston backward” .
Press the dual cartridge into the
cartridge tray 2till it stops.
Mount the mixer.
☞
Mount the F-adapter 14.
The adapter has to be ordered
separately.
Notice!
Pay attention to product holes on the
cartridge! The location of the holes in the
adapter and the adapter connection must
match.
C Type Cartridge
Switch hand lever valve 7to the position
„Piston backward” .
Press the dual cartridge into the
cartridge tray 2till it stops.
☞
Mount the C-adapter 13. The adapter
has to be ordered separately.
Notice!
Pay attention to the divider plate on the
cartridge! The position of the groove in
the adapter and the divider plate must
match.

Connecting the Unit
Caution!
It is only monitored the pressure of component A at the moment.
It is important to ensure that the pressure of component B
–is always sufficient during operation and
–Is never set to 0 bar!
Connect the cord to the control unit or
PLC, see pin assignment at section 8.2.
Connect supplied pressure hose to the pneumatic connection 3.
4.6
Adjusting the Proximity Switches
Factory setting of both sensors are the “Empty”position.
Is it necessary to readjust, do the following steps:
Put in an empty dual cartridge.
Drive piston forward until it stops.
Loosen the slotted screw a little bit.
Move the proximity switches 10 and 11
forwards over the “Empty point” (the
yellow LED lights shortly) in the groove.
Move the proximity switches 10 and 11
backwards till the “Empty point” (the
yellow LED lights permanently) in the
groove.
Tighten the slotted screw in the desired
position.
Use a small flat-bladed screwdriver.
Tightening torque: 2 Nm max.
