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 authorised specialist personnel. Under the terms of these
operating instructions, specialist personnel are persons who can recognise 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 manner. Further safety-related notices are marked in the individual sections of this
documentation.

3 Structure and functionality
3.1 General information
The H1280 hot-runner controllers are especially suited to the temperature control of hot runner moulds on injection
moulding machines. In use, the controllers are connected directly to the mould via cables.
During operation, the hot runner controllers deliver electric current to the heating units for an injection mould. The so-
called heating current leads to an adjustable temperature increase in the heating units and hence in the mould.
Continuous temperature monitoring takes place in parallel via connected thermocouples. In the event of deviations
between the actual temperature 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 either 6, 12, 18, 24 or 36 heating zones.
3.2 Structure
A 12-zone controller is shown by way of example in the figures that follow. All the designated components are identical
on controllers with more than 12 heating zones.
Figure 1 - Housing front

(7) Alarm socket (8) RS485 connection (9) Ethernet connection
(10) Digital input (11) Fuse (12) Status LED
(13) Power board

Bedienungsanleitung H1280
HASCO hot runner 9
3.2.1 Display (1)
The resistive touch display reacts to finger pressure or can be operated with standard commercial pens that have a
rounded plastic tip. For optimum operation, the display can be adjusted to four different positions. This allows an ideal
reading and operating angle to be obtained.
Please note: sharp, pointed objects can damage the display.
3.2.2 LED strip (3)
The controller status is depicted in colour in an LED strip that is visible from a long way off. This permits a rapid
assessment of the current controller and mould status.
3.2.3 Power boards (13)
The connected heating units are controlled via compact power boards, as is the temperature measurement of the
thermocouples. Each power board contains the electronics for heating and measuring six heating zones. The
individual boards are mounted at the side of the housing. The cooling element visible from the outside is used for
optimum heat elimination and thus increases the service life of the installed electronics. The fuses for the load outputs
(11) are located beneath the cooling element.
Each zone is switched off separately via relays on the power board so that individual zones can be switched off
individually, and seamless production is always guaranteed.
In addition to the fuse for the load outputs, each power board (13) contains an internal second fuse that is necessary for
operation in triangular supply networks. There is also a control fuse on the internal wiring terminals.
3.2.4 Connections
In addition to the tiltable display, the front of the housing also has a USB connection. All the other connections are on
the rear of the housing. Apart from the thermal and load connections, each controller has alarm contacts, digital inputs
and an Ethernet connection.
3.2.4.1 USB connection (2)
The USB connection makes it possible to save and load controller settings, export service files and also load firmware
updates via a USB stick.
3.2.4.2 Ethernet connection (9)
The Ethernet connection is used for communication with additional controllers or an injection moulding machine and is
located on the rear of the housing.
3.2.4.3 RS485 connection (8)
The RS485 interface is used for communication with injection moulding machines and is located on the rear of the
housing.
3.2.4.4 Alarm contacts (7)
Each controller has three potential-free alarm contacts that are fed out via a socket on the rear of the housing. The alarm
contacts open as soon as the controller issues a warning or an alarm. A list of the possible messages is given in Chapter
5.3.2.2.4. A wiring diagram of the alarm contact socket is shown in Chapter 8.2.
3.2.4.5 Digital inputs (10)
The controller evaluates 24V DC signals via a 15-pole D-SUB input. The digital inputs are used for the external activation
of functions such as standby, switching the setpoints or locking the outputs. Chapter 8.3 shows the assignment plan for
the digital inputs with the corresponding functions.
The digital inputs are PLC compatible, i.e. they operate over a voltage range of 13...30 VDC with a typical current
consumption of approx. 8.5 mA.

3.3 Identification marking on the controller
The type plate is mounted on the side of the controller housing. It contains the type designation with the number of
zones, the electrical connection data and the manufacturer’s data.
Figure 4 - Type plate
3.3.1 Wiring of the plug systems
The plug-in connectors for connecting up the temperature sensors and heating elements to a hot runner are available
on the rear of the controller. The customer-specific wiring plan for the plug-in systems is located on the side of the
controller housing (see Figure 6 for an example).
Figure 5 - Wiring of plug systems
4 Commissioning
4.1 Electrical connection
Important! Before the device is connected to the supply voltage, a check must first be
performed to ensure that the mains electricity conditions comply with the specifications on
the type plate.
The electrical connections must be performed by a qualified electrician. Commissioning
and operation while the controller is running are only to be carried out by authorised
qualified personnel.
Switching off all the outputs or individual zones will not protect any of the outputs against
hazardous voltages. Before working on the connected heating elements, the associated
connections must be unplugged, or the entire device disconnected from the mains power.
Before the device is opened, it must be disconnected from the mains power.

Bedienungsanleitung H1280
HASCO hot runner 11
4.1.1 Mains electricity
Before connecting the device to the mains voltage, a check must be conducted to ensure that the mains electricity
system is correct. The hot runner controllers are prepared by default for operation in a star network (3x400VAC + N +
PE) but can also be operated in a triangular network (3x230VAC + PE). For operation in a triangular network without a
neutral conductor, it is essential to observe the local regulations for the installation of electrical systems. The terminals
in the controller must be bridged accordingly for use in a star or triangular network. Annex 8.1 contains a clear terminal
connection diagram.
4.1.2 Connection to the mains electricity
To ensure correct operation, the hot-runner controller is connected to the low-voltage mains by means of the connection
lead attached to the device.
4.1.3 Connection of the mould
To connect the individual control zones to the corresponding injection mould, use must be made of appropriate leads
for the sensor and heating unit connection.
Please note: it must always be ensured that the internal wiring, the wiring of the cable
set and the wiring in the mould are suitably coordinated with each other.
Important! To exclude any effects of potential shifts, the injection moulds that are
connected up must be properly earthed in all cases.
4.2 Operating and display concept
4.2.1 Main switch
The main switch is located on the rear of the housing. The switch must
be activated to switch the controller on and off.
4.2.2 Status display
The controller status is indicated on a circulating LED strip. In normal operating mode, this display will be green. In the
event of a warning or an alarm, the display will change to yellow or red (traffic light system).
4.2.3 Operation
The hot runner controller is operated exclusively via the integral 7” touch display (Figure 1) on the housing front.
Please note: The cooling unit can become hot during heating. Avoid touching the
heating unit.

The following operating modes are defined:
Operating mode Function
Normal operating mode In normal operating mode, the hot runner controller will control the output in
such a way that the measured temperature attains a specified setpoint
value. The output level (0...100%) at the output is calculated automatically.
In steady state operation, the actual value and setpoint value will be
identical.
Manual operation During manual operation, a constant output level will be maintained at the
heating output. 0% means that the heating output is permanently off, 100%
means that the heating output is permanently on. Manual operation can be
used, for example, to manually maintain operation of the control zone until
a defective sensor is replaced.
OFF Zone inactive = switched off. If the sensor is connected, the temperature

5.3.1.2.2 Sensor fracture monitoring
1. 2. 3.
Setup > Monitoring > Sensor fracture
The controller behaviour in the event of sensor fracture during normal operation is set out here.
Behaviour
Output level 0% The zone reports an alarm and adjusts the output level to 0%.
Mean output level
YM
The zone reports a warning under sensor fracture and then switches to the
previously averaged output level.
Defined output
level
The zone reports a warning under sensor fracture and then switches
permanently to the output level that can be adjusted here. The output level
can be specified after pressing the button and is displayed at the zones.

Output level of
reference zone
The zone reports a warning under sensor fracture and then switches to the
output level of a reference zone that can be defined here. The reference
zone can be specified after pressing the button and is displayed on the
zones with Zxxx (xxx = number of the reference zone).
5.3.1.2.3 Residual current monitoring
1. 2. 3.
Setup > Monitoring > Residual current
Behaviour
Do not report Residual current monitoring is switched off
Report only Residual current monitoring detects residual currents that flow on account of
moisture in the mould or insulation damage.
If “Report only” is selected, residual current monitoring is activated and a warning is
generated if the limit value is exceeded.
Report and dry
out
If “Report and dry out” is selected, residual current monitoring is activated. If the limit
value is exceeded, a warning will be generated and, in addition to drying out, all the
zones will be heated up to 100°C until the residual current falls below the limit value
again.
The factory setting is: Report and dry out

Output level
reference
value
The output level calculated during normal
operating mode can be monitored. If the
calculated value deviates from this reference
value, it could be a sign of an irregularity in the
controlled system. There could perhaps be
leakage in the nozzle.
Setting this to “0” switches off the monitoring.
