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

feed 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)

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– the empty cartridge has been replaced by a filled one and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.
