Status Indicators
After the module has been inserted into a terminal base (and power
is applied), the module runs an internal boot up sequence and self
test. If this test passes, the green POWER indicator turns on and
the FP-AO-200 informs the network module of its presence. When
the network module recognizes the FP-AO-200, it sends initial
configuration information to the FP-AO-200. After processing this
initial information, the green READY indicator turns on and the
FP-AO-200 is in its normal operating mode. In addition to the
green POWER and READY indicators, each channel has a red,
numbered, error status indicator. For more information, refer to
the section on Open Loop Detection in this document.
Isolation and Safety
CAUTION: Read the following information before
attempting to connect ANY circuits which may contain
hazardous voltages to the FP-AO-200.
This section describes the isolation of the FP-AO-200 and its
compliance with international safety standards.
The field wiring connections of the FP-AO-200 are isolated from
the backplane provided by the terminal base with an optical and
galvanic isolation barrier designed and tested to provide protection
against fault voltages of up to 3000 Vrms. In addition, the
