Analog Output 1 and 2

4.1.2
The analog outputs are adjustable (e.g. for a temperature dis-
play device) to:
 0–20 mA or 4–20 mA
Furthermore, the following adjustments can be done:
 Analog Output 1 always provides the measured tempera-
ture (always the temperature selected and displayed on the
device display and the control window in SensorTools; see
also 7.2.2 Control window).
(Note: With older firmware versions, the same settings are
possible as at analog output 2. A firmware update to the lat-
est version eliminates this possibility and prevents, that the output of analog output 1 is accidentally
different to the displayed temperature signal. Firmware update see section 8).
 Analog Output 2 can be assigned to provide different signals:
- Flame temperature
- 2-color temperature
- 1 channel temperature (optional channel 1 or 2)
- Device temperature
- Control output (= manipulated variable) when equipped with PID controller

Configurable Inputs / Outputs

4.1.3
3 ports are each available as:
 Digital output: output of a switching signal (invertible, see under
 Various settings 
7.2.3
- Device ready to operate (device ready and error-free after self-
test)
- Material detection (limit switch turns on when exceeding the
beginning of temperature range)
- Limit switch when a certain temperature threshold is exceeded
or falling below
- Exceeding the maximum allowed device temperature
- Signal strength too low (as dirty window alarm function: enables to detect the degree of contamina-
tion of the pyrometer's optics, viewing window or identify interferences (dust...) in the IR sensor's
sight path and trigger an alarm if necessary).
 Digital input: A voltage pulse of 24 V, pulse
length adjustable via software (minimum 3 ms,
factory settings 100 ms)

source, some parameters can be adjusted externally between
their smallest and largest setting value:
- Soot factor (0 mA = 0.5; 20 mA = 2.5)
- Emissivity slope (0 mA = 0.8; 20 mA = 1.2)
- Emissivity for every channel (0 mA = 0.05; 20 mA = 1.2)
