Siemens SITRANS TSinsert - Setting the Fault Current of the Internal Transmitter with Switch to ≥ 21 Ma

WARNING
Undetected failure in devices with functional safety
Note the following:
• For the maximum current output signal to be output, set the measuring range within the
maximum permissible measuring span. You can 󹪝nd the maximum permissible measuring
span of your measuring cell in the section Technical data (Page 127).
• Note that a saturation limit > 21.5 mA increases the risk of undetected failures.
• When you con󹪝gure your process control system, the analog input must distinguish
between the measured value at saturation (current is ≤ 21.5 mA) and high fault current
(current is ≥ 22.0 mA).
8.5 Setting the fault current of the internal transmitter with switch to
≥ 21 mA
Introduction
You set the fault current of the internal transmitter from ≤ 3.6 mA to ≥ 21 mA with the switch
on the display.
A fault current ≥ 21 mA is not permissible for operation of the device with functional safety.
Functional safety cannot be activated with a fault current ≥ 21 mA.
