Topics covered in this chapter:
• Power up the transmitter
• Check meter status
• Make a startup connection to the transmitter
• (Optional) Adjust digital communications settings
• Verify mass flow measurement
• Verify the zero
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
1.
Ensure that all transmitter and sensor covers and seals are closed.
DANGER!
To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.
2. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. The transmitter is
self-switching and will automatically detect the supply voltage. When using DC
power, a minimum of 1.5 amps of startup current is required. During this period,
Alert 009 is active. The diagnostic routines should complete in approximately
30 seconds. The status LED will turn green when the startup diagnostics are
complete. If the status LED exhibits different behavior, an alert is active.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics
can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial
startup, or if power has been off long enough to allow components to reach ambient
temperature, allow the electronics to warm up for approximately 10 minutes before
relying on process measurements. During this warm-up period, you may observe minor
measurement instability or inaccuracy.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect
measurement accuracy.
