Hot runner controller profiTEMP+ SYSTEM

The hot runner controller for the control cabinet based on profiTEMP+

Hot runner controller profiTEMP+ SYSTEM

profiTEMP+ SYSTEM is a modular system that allows Meusburger’s proven hot runner control technology to be easily integrated into the control cabinets of injection molding machines. This offers advantages for the machine manufacturer and for the manufacturers of plastic parts.profiTEMP+ SYSTEM relieves the central unit of the injection molding machine and ensures higher quality in the injection molding process. The range of functions familiar from profiTEMP+ and the robust, tried-and-tested control algorithms ensure consistent quality of the parts produced.profiTEMP+ SYSTEM has a service-friendly design that is more compact than any other hot runner controller and can even fit into tight control cabinets.

  • Options offer individual variants
    • Saving on thermal cables by means of temperature measurement remote from the controller
    • External reference junction when using copper cables instead of thermoelectric cables
    • Additional measuring zones without heating outputs (e.g. with TCBOX)

Function overview

Temperature control

  • PID control algorithm optimised for temperature control of hot runner systems
  • Fully automatic auto-tuning calculates the optimum control parameters in the heating phase

Basic functions

  • Zone in control mode or actuator mode
  • Temperature reduction through standby, temperature increase through boost (optionally time-controlled)
  • Zones can be switched in parallel Guide zone operation with missing or defective sensor
  • Automatic guide zone operation after sensor break
  • Automatic actuator operation after sensor break (with output level takeover)
  • Manual / time-controlled heating release after switching on
  • Smart Power Limitation – exact limitation of power output in case of overload of the mains connection

Sensor inputs

  • Thermocouple type J, L and K configurable
  • Resolution 0.1°F/0.1°C
  • Optional decentralised measured value acquisition (thermocouple type J, L and K or Pt100)

Heating outputs

  • Operation in pulse group mode or phase control depending on the operating status
  • Heating current display and monitoring
  • Optional residual current measurement
  • Zone-by-zone safety shutdown when a critical fault is detected

Monitoring functions

  • Temperature alarm limits above and below setpoint (adjustable)
  • Overtemperature / undertemperature (adjustable)
  • Heating current outside the tolerance band (adjustable)
  • Heating circuit interrupted
  • Short circuit in the heating circuit
  • Fuse failure
  • Sensor breakage and polarity reversal,
  • Short circuit in the sensor circuit
  • Fault current
  • Power controller in the heating circuit permanently switched on
  • Early detection of leaks through process monitoring

Heating up

  • Classic start-up mode with preselectable start-up time to bake out the heaters
  • Heat’n’Dry – controlled, gentle heating to fully bake out the heaters (with fault current control)
  • Even, guided heating with automatic ramp
  • Stage heating – heat up zones in groups one after the other

Diagnostic functions

  • MoldCheck – Fully automatic check of the status of heaters and sensors in the hot runner, wiring check
  • MoldSnapshot – Snapshot of the status of the hot runner. Multiple snapshots can be compared

.

Digital inputs & outputs

  • 3 digital inputs (function adjustable)
  • 1 function/alarm output designed as potential-free relay contact (function adjustable)

Communication/data interfaces

  • Ethernet (e.g. OPC 40082-2, VNC, Modbus TCP)
  • CAN (CANopen)
  • RS485 (e.g. PSG II, MODBUS RTU)
  • RTE (VARAN, EtherCAT or Profinet IO)

Standard configuration

In most cases, a profiTEMP+ SYSTEM hot runner controller is used in the standard configuration with residual current detection and an alarm output, which is why the controller module pT+CUR, the pT+IO (B), at least one pT+RACK (C), the appropriate number of plug-in cards HTC 06/15 R (D), residual current transformer RCT are provided.

Minimum expansion

With the minimal expansion, the costs of the hot runner controller can be optimised without significantly sacrificing the main range of functions; the complete range of functions is available, only the residual current measurement is omitted. Therefore, the residual current transformers can be omitted. If no digital inputs and outputs are required, a flexoTEMP BE replaces the pT+IO. pT+CUR (A)

  • a flexoTEMP BE (B)
  • at least one pT+RACK (C)
  • the appropriate number of HTC 06/15 R plug-in cards (D)
  • are included in a minimum system.

    Full extension

    All possible options are shown in the full configuration:

    • Fault current detection (H1/2 and D) using the residual current transformer PCT and the IO module pT+IO.
    • Measurement inputs for external cold junction in the event that no thermal compensation cables are used between the mould and controller (C). For example, if all cables between the mould and controller must be designed to be suitable for drag chains.
    • External temperature detection in the event that measured temperature values are recorded close to the mould and transmitted to the controller via a data connection (F).
    • Additional measurement zones if these are required in addition to the control zones (G).
