• profiTEMP+ VCON cascade control unit

FEATURES

• Enables independent adjustment of each valve gate nozzle
• The operating mode of each control output is configurable.
• Operating mode 1 - solenoid valve control
• Opening and closing of the valve pin at maximum speed
• Control of up to 3 switching cycles (open/close) per cycle
• Path-dependent or time-dependent switching cycles
• Operating mode 2 - proportional valve control
• Opening and closing the pin using a multi-stage profile. Pin movement at reduced speed or holding the pin
• With path-dependent control, the dosing signal is detected via external displacement sensor or analogue signal from the injection moulding machine

VARIANTS

The housing is identical to the profiTEMP+ hot runner controller and allows a large number of variants:

• As valve gate nozzle control unit – up to 32 control circuits in desktop housing
• As a combination unit together with the profiTEMP+ temperature controller in one housing with a single operating panel

DISPLAY/OPERATION

• Brilliant 7" touch screen with several language options
• Intuitive device operation like the already familiar profiTEMP+ hot runner controller, with gesture based controls similar to smartphones
• A sufficient number of switching cycles/profile files can be saved for different moulds
• Detailed information and status display of the process, particularly the pin position; additional information about cycle counter, cycle time,....
• Monitoring of process parameters and alarm outputs

Design

• Space-saving and service-friendly design, equivalent to the design of the profiTEMP+ hot runner
• Compact, robust metal housing ensures a long service life.

Optional

• Input temperature sensor and pressure sensor for the time adjustment of the switching cycles to the process
• Pin position monitoring to check the pin status in real time
