4.6 Simulation function
The simulation function is helpful when setting up the installation�
Via the SIM menu (→ 10.3.5), it is possible to activate a simulation of any
measured temperature within the measuring range� The simulation influences the
display and the outputs� After an adjustable period of time, the simulation function
stops automatically� To indicate that the simulation mode is activated, the display
alternates between the simulated measured value and "SIM"�
4.7 Test function
The infrared temperature sensor has an internal test function to check the com-
plete signal processing, the switching output and the analogue output�
The test function is activated by a static signal on pin 5 or via IO-Link� The test
function simulates a radiation detector signal which generates an output current
of 20�5 mA and triggers the switching function when the sensor operates correctly
unless the switching output has already switched depending on the configuration�
[OL] is displayed�
The unit remains in the test mode as long as the static signal is on pin 5� If the test
function is started via IO-Link, the duration is 10 s� After that, the unit automatically
returns to the RUN mode�
To trigger the test function a static signal (10���34 V to IEC 61131-2) > 300 ms has
to be applied via pin 5� The test function is deactivated via a static "low" signal
> 300 ms on pin 5�
If the test function is not used:
► Put the test input (pin 5) to minus supply�
► Alternatively use a 4-pole socket in which pin 5 is not connected�
