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 congure 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.
