Parameterization and commissioning
Before commissioning, ensure the following:
• Installation of the device according to regulations.
• Correct connection of the cables.
• No damage at the device and connection cables.
• Tight seat of the screws at the terminals. Correct tightening torque: 0.5 ... 0.6 Nm.

A load resistance of at least 250 Ohm is necessary for a proper functioning
of the HART communication in the output circuit
(e.g. input resistance of the input assembly).
The maximal output load is reduced accordingly.
If the load resistance is not available, an external resistor can be used
additionally.
Type of supply
Connection
