Safety instructions
Please read this document completely and carefully before commissioning or
operating the device.
2.1
Intended use
The hot runner controller is used to control the temperature of heating circuits and is de-
signed for use under precisely defined conditions, such as supply voltage and temperature.
The operator must therefore ensure that the controller is only used under operating condi-
tions that comply with the technical data. The manufacturer is not liable for damage resulting
from non-compliance with the intended use.
The hot runner controller is not suitable for use beyond the limits defined in the technical data
and during its design. In addition, the use of spare parts from third parties and the implemen-
tation of non-described maintenance activities constitute failure to comply with the intended
use.
Alterations,
conversions and other modifications are made exclusively at the operator’s own
risk and could pose safety hazards. The manufacturer and distributor of this device cannot
be held liable for direct and indirect damage resulting from improper handling or treatment.
2.2
Information for operators and users
The controllers are operated on the low-voltage network. The relevant safety regulations
must be observed when connecting up the controller and performing maintenance on it. In
addition, the local and general safety regulations must be observed for its installation and
operation. The operator is responsible for compliance with these regulations. The operator
must additionally make this documentation available to the user and provide instruction in the
correct operation of the device. The user must be familiar with this documentation. In order to
ensure reliable and safe operation, the individual user is required to observe the information
and warnings.
The controllers may only be brought into operation by authorized specialist personnel. Under
the terms of these operating instructions, specialist personnel are persons who can recog-
nise and assess the dangers associated with the work entrusted to them on the basis of their
specialist training, their experience and their knowledge of standards.

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 man-
ner. 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
control of hot runner molds on injection molding machines. In use, the controllers are con-
nected 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 or 6 heating zones.
3.2
Structure
Housing front: The pro CONTROL BASIC hot runner controller is operated from the housing
front with 12 keys. 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
provide information about operating modes and messages of the individual zones. The con-
troller status is visualized in color via a fault message display visible from afar. In control
mode this display lights up green. In case of a warning or alarm, the display changes to yel-
low 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 functions can be found in
chapters 4.2 and 5.
Back of housing: All connections for the hot runner controllers and the 3-pin main switch for
switching on and off 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 con-
nection 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.
