The status of the unit of the selected Flow-5 flowmeter flashes green (fast).

Delete flow meter from overview

The flow meter overview shows all flow meters that have flow meter identified once on the temperature control unit, regardless of whether they are currently connected to the temperature control unit or not. If a Flow meter Flow-5 is no longer required on a temperature control unit, it can be deleted from the memory of the Thermo-6 temperature control unit. Deleting is only possible when the Flow meter Flow-5 is not connected.

  1. Select [Flow] > [Flow A, Flow B, ...] > [Settings ] > [DFM_Serial-No.]
  2. By tapping on the symbol (), the respective flow meter is deleted.
    → The labelling, the address range and all monitoring settings are deleted

NOTE!

A deleted Flow meter Flow-5 can be re-registered and assigned at any time by connecting it to the Thermo-6 temperature control unit.

Activate and deactivate measurement circuits

Individual measuring circuits of the Flow meter Flow-5 can be activated or deactivated depending on the application.

  1. Select [Flow] > [Flow A, Flow B, ...] > [Measuring Circuit Active]
  2. Activate or deactivate the measurement circuits with the slider (, ).

NOTE!

When measurement circuits are deactivated (slider switched off), no actual values are displayed, no limit values are monitored and no alarms (e.g. Sensor failure) are emitted.

Process monitoring

In the standard setting, the limit values for process monitoring are automatically determined and set after each device is started, in accordance with the selected monitoring level. If automatic limit value determination is not desired, it can be set to manual setting or switched off. See the description on the following page → Monitoring.

If the monitoring type act set to manual, the temperature or flow rate limit value can be set separately for each measuring circuit of the Flow meter Flow-5, or the monitoring can be switched on or off separately.

  1. Select [Flow] > [Flow A, Flow B, ...] > [Monitoring ] > [Temperature or Flow Rate]
  2. Switch on monitoring on or off with the slider (, )
  3. Set the temperature or flow rate limit value to the desired value

The selected monitoring type (automatically, manual, OFF) and the set monitoring level (fine, middle, rough) apply to both the Thermo-6 temperature control unit and the Flow-5 Flow meter Flow-5. A separate setting is not possible.

Operating mode

Remote control

In order to transfer the measurement values of the Flow-5 flow meter to an external controller, the following Interfaces are available for a connection between the Thermo-6 temperature control unit and the machine control system.

  • Ethernet interface OPC UA(EUROMAP 82.1 Release 1.01 / OPC 40082-1) → Thermo-6 interfaces
  • Serial interface DIGITALDIGITAL (ZD) → Gate-6 interface

The following measurement values can be transferred from the machine upon request. Which measurement values are requested from the machine depends on the transmission protocol used and the software version of the machine.

  • Flow rate per measuring circuit
  • main line temperature per flow meter Flow-5
  • return line temperature per measuring circuit
  • Temperature difference return/flow per measuring circuit

To be able to communicate with the external control system via the Interfaces, see the description on the following page → Remote control

Special feature of the Interface DIGITAL

Advanced interface protocol

In order for the measured values to be transferred from the flow meter to the machine via the serial interface, the corresponding protocol 1, 4 or 5 must also be extended on the machine side.

NOTE!

The hardware and software required for the machine control system must be clarified with the machine manufacturer.

The following machine manufacturers are known to have implemented an extension:

ManufacturerProtocolMeasured value display

Arburg

1
  • Flow rate per measuring circuit 1.. 8

Sumitomo Demag

  • Flow rate per measuring circuit 1.. 8
  • return line temperature per measuring circuit 1.. 8

Simulate flow meter as a device

If this function act switched on, each measuring circuit is assigned an address by the external flow meter for communication with the machine. The Simulate Flow as a unit function enables the transfer of flow values from external measurement circuits to machine controls that neither support the extended interface protocol 1, 4 and 5 nor the OPC UA Euromap 82.1 Ethernet interface (EUROMAP 82.1 Release 1.01 / OPC 40082-1). This allows the flow values of the external flow meter Flow-5 to be transferred to the injection moulding machine without changing the software.

NOTE!

Prerequisite:

  • Software SW61-1_2306 or higher → Unit software
  • DIGITAL (ZD ) serial interface, protocol 1, 4 or 5 → Gate-6 interfaces
  • Machine control supports the required number of device addresses (e.g. For a Thermo-6 with a flow with 4 measurement circuits, 4 unit addresses must be supported by the machine control!)
  1. Select [Setting] > [Remote Control] > [Simulate Flow as a unit] (→ only available if a flow meter (Flow) is also connected) 
  2. Use the slider (, ) to turn the function on or off.
    → A simulated unit address is automatically assigned to each measuring circuit.
    → Inactive measurement circuits also receive an address assignment.

The address set on the Thermo-6 temperature control unit is used as the starting point for address assignment. The address range used is displayed in the address field of the temperature control unit (e.g. “3..6” if the address “3" is set to the temperature control unit and a flow with 4 measuring circuits is connected). If the following addresses have already been assigned elsewhere from the starting point, this will be notified by a warning. An address (starting point) with a subsequent free address range is required for the number of measurement circuits.

NOTE!

It is not possible to manually and individually assign addresses to the simulated device addresses for the measurement circuits.
