OPERATION
This chapter contains information that is needed to operate the DPT145.
Transmitter Start-Up
When the transmitter is connected to power supply, there is a delay of
five seconds as the transmitter starts up. After the start-up is complete,
the transmitter will behave according to the configured serial mode:
- In STOP mode, the transmitter outputs the transmitter model and
software version.
- In RUN mode a measurement output starts immediately.
- In POLL mode the transmitter does not output anything after power-
up.
- In MODBUS mode, the transmitter does not output anything after
power-up.
For a description of the modes, see section Set Serial Line Operating
Mode on page 41.
For a description of how the diagnostic functions of the sensor affect the
availability of live measurement at start-up, see section DPT145 Start-up
Sequence on page 20.
