The device is checked carefully prior to delivery and has passed the tests specified in the test
plan for its production, in conformity with the manufacturer’s valid quality guidelines. To prevent
any damage to the controller, it must be transported and stored in the correct manner. Further
safety-related notices are marked in the individual sections of this documentation.
3 Structure and functionality
3.1 General information
The pro CONTROL BASIC hot runner controllers are especially suited to the temperature con-
trol of hot runner molds on injection molding machines. In use, the controllers are connected
directly to the mold via cables.
During operation, the hot runner controllers deliver electric current to the heating units for an
injection mold. The so-called heating current leads to an adjustable temperature increase in
the heating units and hence in the mold. Continuous temperature monitoring takes place in
parallel via connected thermocouples. In the event of deviations between the actual tempera-
ture recorded and the temperature set on the hot runner controller, the heating current is
automatically adjusted until the two temperatures are identical.
The controllers are available in different variants. These differ solely in terms of the number of
control circuits that are possible – which are also referred to as heating zones. Depending on
the variant, hot runner controllers are available with 2 to 12 heating zones (in steps of 2).
3.2 Structure
Housing front: The pro CONTROL BASIC hot runner controller is operated from the housing
front. In addition to the main switch for switching on and off, the controllers have 12 keys for
convenient operation. Furthermore, the front contains all visualization elements. The setpoint
and actual values of the individual zones are displayed via 7-segment displays. If required, the
display can be switched over to heating current and output rate. In addition, status LEDs pro-
vide information about operating modes and messages of the individual zones. The controller
status is visualized in color via a led strip visible from afar. In control mode, without a current
error or warning message, this display lights up green. In case of a warning or alarm, the
display changes to yellow or red (traffic light status). This allows a quick assessment of the
controller status even from a distance. A detailed description of the display and operating func-
tions can be found in chapters 4.2 and 5.
Back of housing: All connections are located on the back of the housing. In addition to the
connecting cable, which is used for connection to the supply voltage, the controllers offer a
further connection for a potential-free alarm contact and a 24V digital input for external control
of the set-back operation. The connection to the hot-runner mold is established via plug-in
systems.
