2 Quick start
2.1 Applying power
The transmitter must be powered up for all configuration and commissioning tasks, or for process
measurement.
Procedure
1. Verify that the cables are connected to the transmitter as described in the installation manual.
2. Verify that all transmitter and sensor covers and seals are closed.
WARNING
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.
3. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period, the
Transmitter
Initializing
alert is active. The diagnostic routines should complete in approximately 30 seconds.
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.
When the flowmeter has completed its power-up sequence, if the default settings are in effect:
• The display will show the current mass flow rate and measurement unit.
• If there are any active fault or informational alarms, the alert banner displays until the alert has been
manually acknowledged.
• If the alert has been acknowledged but is still active, the alert icon displays above the menu button, and
the
Alert List menu appears at the top of the main menu.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect measurement accuracy.
Procedure
Wait approximately 10 seconds for the power-up sequence to complete.
Immediately after power-up, the transmitter runs through diagnostic routines and checks for error
conditions. During the power-up sequence, the
Transmitter Initializing
alert is active. This alert
should clear automatically when the power-up sequence is complete.
