- Analog output 1 always provides the measured temperature (that is always the temperature
shown in the control window of SensorTools software (see also 7.2.2).
- Analog output 2 (will be displayed after expansion with ) is configurable, here at output tem-
perature you can select which output signal should be provide:
- The ratio temperature or that of each channel can be set assigned to the output.
- Device temperature is the internal pyrometer temperature (scaled from 0 to 100°C).
- Controller output: The manipulated variable of the PID controller is set here as standard.
- “no output” disables the analog output.
-
Further adjustments can be made by extending the setting range
- Adaptation (see 6.9): The temperature range assigned to the analog outputs can be scaled
to the required application. Reduce the range for specific adaptation to the application, or en-
large the range to replace the pyrometer to systems with larger temperature range.
With the reset button, the temperature range is set to the adjusted sub range.
Upscale-burnout function:
- Disabled upscale-burnout (standard): The analog output at sudden shadowing of the pyrome-
ter’s view field is the lowest current (0 or 4 mA).
- With enabled upscale-burnout function, the analog output at sudden shadowing of the pyrome-
ter’s view field is set to the maximum current of 20 mA. This can be desirable, for example, in a
furnace monitoring when the controller otherwise would recognize a cold oven and heat up fully
and possibly burn out the oven.
7.2.3.1 Digital Input / Output Configuration
Each digital input and output can be assigned a function (also see 4.1.3 Digital Inputs / Outputs).
Digital Inputs (activated by voltage pulse or a voltage of +24 V):
- No function: A switching signal at the input has no effect.
- External clearing: Resets the peak value of the peak picker.
- Targeting light on/off: (only available with equipment laser targeting
light): Switches externally on or off the laser targeting light.
- Parameter selector (also see 7.2.5 Setups): For selection and activa-
tion of up to 7 pyrometer configurations, available with the inputs 1-3
(incl. control parameters of the PID controller).
- The inputs are binary coded,
that is:
- with one digital input only one Set-
up can be activated
- with 2 digital inputs there are 3
Setups available
- Using all 3 inputs, 7 Setups can be
accessed and activated
- Activate controller (for PID controller): The control process is activated as long as voltage at the
terminal is present.
- Start / stop controller (for PID controller): Each pulse starts or stops (alternating) the controller.
At all inputs:
- Time settings: A debounce time can be selected, that is, a period the signal at least must be
present at an input to be detected.
