The Air Curtain and Printzone Heaters Control PCA is only present in Latex 360 printers, and is placed inside
the EEbox. The Air Curtain and Printzone Heaters Control is the PCA that controls the power delivered to the
air curtain resistors and the printzone heaters. The AC power input comes from the Main PSU, but there is a
pass through from the input power plug to the PCA AC input. The PCA has a primary non-isolated area, and a
SELV isolated area. The power available is balanced between both subsystems based on burst control, the
control is provided from the same PCA. The Air Curtain and Printzone Heaters Control also controls both
subsystems' fans; the ambient temperature sensor, and the box fan installed for cooling the PCA.
Curing Control PCA:
The Curing Control PCA is placed at the impinging bracket on its left side and executes the servo that applies
the power to the impinging module. The Curing Control PCA is present in all three SKUs; In the Latex 360
printer it controls the impinging sensors (Temperature and pressure) and the Heater Control, and in the Latex
330 & Latex 310 printers, it controls the air curtain fans, and reads the ambient temperature sensor. The
Curing Control PCA has no power (PRI) lines.
Curing Power Interconnect:
The Curing Power Interconnect PCA is placed just above the Curing Control PCA. Both PCAs are housed in the
same fire proof box. The Curing Power Interconnect PCA is connected to power lines and provides the
interconnection interface for the curing module, and for the air curtain resistors (Latex 360 only). The Curing
Power Interconnect PCA is present in all three SKUs.

Electrical configuration
NOTE: An electrician is required for the setup and configuration of the electrical system used to power the
printer. Make sure that your electrician is appropriately certified according to local regulations, and supplied
with all the information regarding the electrical configuration.
