4.1.2 Analog Output 1 and 2
The analog outputs are adjustable (e.g. for a temperature display
device) to:

0
–20 mA
or 4
–20 mA
Furthermore, the following adjustments can be done:

Analog output 1 always provides the measured temperature
(always the temperature selected and displayed in the control
window in
SensorTools ; see also 7.2.2 Control window in
SensorTools ).

Analog output 2 can be assigned to provide different signals:
- 2-color temperature
- 1 channel temperature (optional channel 1 or 2)
- Device temperature
- Control output (= manipulated variable) for PID controller
4.1.3 Digital Inputs / Outputs and Analog Input
7 ports are each available as (configuration under 7.2.3 Device settings and configuration

Digital
Input / Output ):

Digital output of a switching signal (invertible, see under 7.2.3

Various settings

Logic NO / NC)
to:
- Device ready to operate (device ready and error-
free after self-test)
- Material detection (limit switch turns on when ex-
ceeding the beginning of temperature range)
- Limit switch when a certain temperature threshold
is exceeded or falling below
- Exceeding the maximum allowed device tem-
perature
- Signal strength too low (as dirty window alarm
function: enables to detect the degree of contamination of the pyrometer‘s optics, viewing window
or identify interferences (dust...) in the IR sensor’s sight path and trigger an alarm if necessary).
- Controller activity of PID controller, control process within adjustable setpoint limits, control pro-
cess successfully completed, hold time finished.

Digital input: A voltage pulse of 24 V (exception: continuous voltage at "Activate controller"), pulse
length adjustable via software (minimum 3 ms, factory settings 100 ms) under 7.2.3

Digital Input /
Output

debounce time enables:
- Clear of peak picker (see 6.7 )
- Start / stop controller (PID controller, see 7.2.4 ).
- Activate controller: The control process is activated
as long as voltage at the terminal is present.
- Load (stored) pyrometer configuration (also PID
controller parameters) (only digital inputs 1-3, see
under
7.2.5 Setups ).
- Switch on / off laser targeting light (when equipped
with laser targeting light).
(the targeting light will automatically switched off after 3 minutes if it is not switched off manually.
Adjustable via software under
7.2.3

Laser targeting light settings ).
CAUTION, Laser Radiation, Laser Class 2:

Never look into the direct or reflected laser beam.

Do not point the laser to anyone.

If laser radiation hits the eye, the eye should be averted immediately.
