FLEX I/O Isolated Input HART Analog Module 23

Publication

1794-IN115C-EN-P - April 2009

Status Indicator

The OK status indicator is bicolor, red, and green. The indicator

flashes green for these reasons:

• The module configuration word is zero (for example,

powerup reset condition).

• The 24V DC user power is off.

• The module is in Configuration mode.

The indicator displays red to indicate the module did not pass the

initial hardware test. Recycle power in response to this display.

After powerup, if the status indicator is not flashing green or solid

green, recycle module power to verify a proper reset of the bus

interface.
