6 Startup

6.1 Initialization

After wiring has been connected, power can be supplied to the

transmitter. During initialization, the transmitter performs a self-

diagnostic test and produces the following series of displays,

sequentially:

1. All pixels on

2. All pixels off

3. All eights

4. All pixels off

5. Copyright notification

For DC-powered transmitters

, at startup, the transmitter power source

must provide a minimum of 2 amperes of inrush current at a minimum of

12 volts at the transmitter's power input terminals. If the startup voltage

is pulled below 12 VDC, the transmitter could remain in the startup loop

indefinitely.

After the self-test is complete, one of 10 possible process variable

screens, such as the one depicted below, displays:

If the flowmeter is operating properly, the blinking "Msg" (message)

indicator appears in the bottom right corner of the screen to indicate

power has been cycled.

• To clear the "Msg" indicator, repeatedly press the Scroll button until the

display reads "Sensor OK *POWER / RESET*".

• To clear the message, press the Scroll button.

If the message does not clear, or if error messages appear, refer to

Section 7.4

, page 73, which provides an overview of diagnostic and

error messages.
