Power up the transmitter

The transmitter must be powered up for all configuration and commissioning tasks or for
process measurement.
Procedure
1.
2. Turn on the electrical power at the power supply.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the
electronics can take up to ten 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 ten minutes
before relying on process measurements. During this warm-up period, you may observe
minor measurement instability or inaccuracy.

WARNING
If the transmitter is in a hazardous area, do not remove the housing cover while
the transmitter is powered up. Failure to follow these instructions can cause an
explosion resulting in injury or death.
Ensure that all transmitter and sensor covers and seals are closed.
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 and begin to flash when the startup
diagnostics are complete. If the status LED exhibits different behavior, an alert is
active.
