Configuring Channels

 

Operational safety!

The TempScan20 and HMI module PowerView3 are not designed for safety-critical applications. The CANopen® protocol and the binary inputs and outputs of the PowerView3 must not be used for safety-critical purposes.

   

Further configuration options

There are further configuration options for the TempScan20. These are described in the PowerView3 operating manual.

 

With the PowerView3, you configure the channels of the TempScan20. The views for individual configuration of each channel can be accessed as follows:

Start Menu -> TempScan20 -> Preferences -> Channels

With enabled access control in the PowerView3, you need at least the rights for the access level Service to configure the channels and store the configuration in the TempScan20.

2100_Channel_Settings

The Pfeil-L and Pfeil-R buttons allow you to switch between the channels.

Configuring Channels

Carry out the following steps for all channels which have a thermocouple connected to them:

  1. Under Status, enable the channel for displaying measured values in the PowerView3.
  2. Assign a Tag (max. five characters) and a Name (max. 20 characters) for each channel.
  3. Under Thermocouple, set the thermocouple type connected to the TempScan20 channel.
  4. For detecting over- and undertemperatures of the thermocouple connected to the channel, configure the upper shutdown threshold (Shutdown High), the upper warning threshold (Warning High) and the lower warning threshold (Warning Low):

    With 3723_minus1 and 3723_plus1 in steps of 1 °C or 1 °F

    With 3724_minus20 and 3724_plus20 in steps of 20 °C or 20 °F

     

    Minimum separation of threshold values

    The threshold values Shutdown High, Warning High and Warning Low must each be separated by at least 10 °C (18 °F).

     

    The TempScan20 signals the exceedance of these thresholds via the CAN bus.

  5. Under Status, activate the checkbox Warning Output if binary output 1 (Warning) is to be activated additionally for the displayed channel in case the temperature warning thresholds are not met.
  6. Under Status, activate the checkbox Error Output if the binary output 2 (Error) is to be activated additionally for the displayed channel in case the temperature shutdown threshold is not met.
  7. If needed, assign the channel to one or several groups under Group. For more information on configuring groups, refer to the PowerView3 operating manual.

Further information can be found in the PowerView3 operating manual.

Saving Configuration

In the Preferences view (accessible via Start Menu -> TempScan20 -> Preferences), tap the Store Setup button to permanently save the following information in the TempScan20:

Otherwise, this information will be lost in the TempScan20 if the TempScan20 is switched off temporarily and is not connected to the PowerView3 when switching on.
