NOTE
Overload, failure due to improperly set voltage (8.2 V / 26 V)!
Failure to comply with these instructions can damage the electronic components.
Prior to start-up, set the Transmitter Supply[01] system parameter to 1 (8.2 V). If the
shunt adapter has been overloaded, it must be replaced.
Switching Thresholds of the Analog Inputs
With the shunt adapter Z 7309, the current measurement of 0/4…20 mA is set at a resolution of
2000 digits.
The switch-on and switch-off thresholds, the open-circuit (OC) and short-circuit (SC) thresholds
and the corresponding fault reaction must be configured in the user program. The line
resistance has already been taken into account with the limits.
