4.1.3 Analog Output 1 and 2
The analog outputs are adjustable (e.g. for a temperature display device):
 0–20 mA or 4–20 mA
 Analog output 1 always provides the measured temperature
(always the temperature displayed on the device display or the
software control window in SensorTools, see also 7.2.2 Con-
trol window).
(Note: With older firmware versions, the same settings are
possible as at analog output 2. A firmware update to the latest
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:
- Measured temperature (always the temperature selected and displayed on the device display and
the software control window; also see 7.2 and 7.2.2 in SensorTools).
- Device temperature
- Manipulated variable of the controller output (when equipped with PID controller).
4.1.4 Configurable Inputs / Outputs
3 ports are each available as:
 Digital output: output of a switching signal (invertible, see under
7.2.3  Various settings  Logic NO / NC) at:
- Limit switch when a certain temperature threshold is exceed-
ed or falling below
- Material detection (only M3): turns on when exceeding the
beginning of temperature range
- Device ready to operate (device ready and error-free after self-test)
- Exceeding the maximum allowed internal device temperature
- Controller activity (only when equipped with PID controller)
 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  Configu-
rable Inputs / Outputs  debounce time ena-
bles:
- Clear of maximum value storage (see 6.3.2)
- Start controller (when equipped with PID con-
troller, see 7.2.4).
- Activate controller: The control process is ac-
tivated as long as voltage at the terminal is pre-
sent.
- Load pyrometer configuration (devices with PID controller also control parameters) (see under
7.2.3  Configurable Inputs / Outputs  “parameter selector” or 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 Device Settings  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 eyes must be intentionally closed and the head
immediately moved out of the beam.
