Output Current Range; Simulated Current Signal For Functional Testing - Siemens ARDOCELL PA 4 Series Operating Manual

s
When using protective windows, the transmission of the window must be
adjusted for the spectral channel. The value to be set can be found in the
specification of the window.
Code page C003 parameter tAU.2
CAUTION!
It is strongly recommended to use only approved protective
windows specified by the manufacturer, which remain neutral
regarding the wavelengths. If you use commercial glass there
is a risk of a faulty measurement due to selective influences.

Output current range

For the pyrometer's two analogue current outputs, select the current loop
scale – (0 - 20 or 4 – 20 mA)—which matches that of the downstream
signal processing equipment (PLC, display device, controller, etc.). At
the pyrometer and at the controller, set the upper and lower limits of the
temperature range and the current loop output signal. Access this setting
using configuration layer

Simulated current signal for functional testing

After initial installation, you should perform a function test to verify that
temperature data is correctly transmitted to the controller. To do so, use
the push-buttons on the pyrometer rear panel to simulate a temperature
reading, which is applied as an output current signal scaled to the se-
lected current range. The appropriate parameter can be accessed via
configuration layer
If the pyrometer is set up correctly, the downstream controller should in-
dicate the values you have entered (only within the scaled range). If
there is a discrepancy, please check the current range scale or the cable
connection.
When you have completed the function test, exit by pressing "
return to normal operating mode.
