Interrupt the power supply to turn off the pyrometer, e.g. by disconnecting the con-
nector.
The operating status is displayed on the LED 4:
▪ Orange in the self-test phase (M3 ca. 2 s; H3 during the initialization and
thermostatic phase for ≤ 3 min.)
▪ Green when the pyrometer is ready
▪ Red when an error occurred (see
4.1.3 Analog Output 1 and 2
2 analog outputs are available (e.g. for a temperature display device):
▪ adjustable to 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 con-
trol window in SensorTools, see also
▪ Analog output 2 can be assigned to provide different signals:
- Measured temperature (always the temperature selected and dis-
played on the device display and the software control window; also
see
7.2
and
- Device temperature
- Control output (= manipulated variable) when equipped with PID
controller
|INFO|
on older models: If the same settings are possible on analog output 1 as on analog output 2, the de-
vice has an older firmware version. A firmware update to the latest version eliminates this possibility and thus
prevents the analog output 1 from accidentally provide a different temperature signal than is displayed (Firm-
ware update see section 8).
4.1.4 Configurable Inputs / Outputs
3 ports are each available as:
▪ Digital output: output of a switching signal (invertible, see under
→ Various settings →
- Limit switch when a certain temperature threshold is exceeded 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

- Clearing the peak picker (see 6.3.2)
- Start controller (devices with PID controller, see
7.3.3).
- Activate controller: The control process is activated
as long as voltage at the terminal is present.
- Load pyrometer configuration (devices with PID controller also control parameters) (see under
Configurable Inputs / Outputs
- 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.
