Flowmeter Startup
3. Insert an appropriate DeviceNet cable into the connector on the transmitter.
When the transmitter receives power, it will automatically perform diagnostic routines, and the
module LED flashes red and green. When the flowmeter has completed its power-up sequence,
the status LED will show a solid green. See Section 7.4 for information on LED behavior. If
the status LED exhibits different behavior, an alarm condition is present. See Section 7.5.
4. Ensure that the transmitter is visible on the network. For information on establishing
communications between the Model 2400S DN transmitter and a DeviceNet tool, see
Chapter 5.
Note: If this is the initial startup, or if power has been off long enough to allow components to reach
ambient temperature, the flowmeter is ready to receive process fluid approximately one minute after
power-up. However, it may take up to ten minutes for the electronics in the flowmeter to reach thermal
equilibrium. During this warm-up period, you may observe minor measurement instability or
inaccuracy.
