- Analog output 1
always provides the measured temperature (that is always the temperature
shown in the control window of
SensorTools
software (see also
- 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
:
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
).
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
): 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.
