- Analog output 1
always provides the measured temperature, shown on the device display or in
the control window (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:
-
“
no output
” disables the analog output.
-
“
Measured temperature
” always applies the measured temperature, shown on the device dis-
play or in the
control window
(see also
-
Device temperature
is the internal pyrometer temperature (scaled from 0 to 100°C).
-
Controller output:
The
manipulated variable
at devices with PID controller is set here as stand-
ard.
-
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 enlarge
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 py-
rometer’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 Configurable Inputs / Outputs
The 3 inputs / outputs can be set as input or output or inactive and assign with a function (also see
Configurable Inputs / Outputs
).
Digital input
mode (activated by voltage pulse or a voltage of +24 V)
- No function
: A switching signal at the input has no effect.
- Extern clearing
: Resets the maximum value of the maximum value
storage.
- 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 activation of up to 7 pyrometer
configurations (incl. control parame-
ters at devices with 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
Note:
Should for example the controller be activated and started externally via a digital input,
this input is obviously as parameter selector no longer available and with 2 inputs there are only
3 pyrometer configurations left.
Additionally when equipped with a PID controller:
- Activate controller
: The control process is activated as long as volt-
age at the terminal is present.
- Start / stop controller
: Each pulse starts or stops (alternating) the
controller.
