Description
3 x 400V +N +PE/50–60 Hz (Trafo optional)
Siemens ® S7 PLC with touch panel
(5.7in. or 10.4 in.)
• Start-up circuit that monitors temperature drops and
temperature fluctuations for all heating zones.
• Multiple storage capability provides easy program selection.
• Permanent sensor failure monitoring with visual display.
• Zero potential output contacts for reporting temperature
drops and temperature fluctuations, and ready for operation
signal.
• Electronic pressure control for manual and automatic
operation with excess pressure cutoff.
• Pressure build-up control with automatic switch-over to
speed regulation during head control.
Temperature Sensors PT100, Ni120 (2)
Heated Zones
Metering Station
Extruder, hose, applicator (additional heating zones optional)
Metering stations are equipped with high-precision gear pumps for
the most demanding applications.
Pumps can be flanged to extruder output or alternatively installed
as satellite PS metering stations with a hose between the extruder
and the pump station.
