5.2 MODE OF OPERATION
The TwinControl system consists of 5 function units: The pneumatically operated high-pressure
pumps for A and B components and for ushing agents, the mixing unit and the control
unit. The two product components are brought to high-pressure by the pumps and an
adjustable, predened mixing ratio is intermixed in the static mixer, from where it is
conveyed to the spray gun.
The system can be operated with one or more spray guns, depending on size and output.
Various functions are controlled by the control unit, such as: ushing, pot life monitoring
or mixing ratio.
Basic principle
The lacquer ows continuously and the hardener is metered (injected) into the lacquer in
portions in intermittent cycles with a slightly higher pressure.
Operation
The required mixing ratio is entered on the electronic controller, and the system can then
be started by pressing the button on the electronic controller. This opens product valve A.
The hardener valve B is then opened in pulses, and hardener is metered in according to
requirements (mixing ratio).
5.3 PROTECTIVE AND MONITORING EQUIPMENT
The following functions are provided for system safety:
External release: e.g., interlock with spray booth's exhaust air
