Reset Pushbutton
Use the reset pushbutton to reset the adapter module and resume
communication when a communication error occurs. (The adapter’s
processor restart lockout switch (PRL) must be in the “locked out”
position.) If the adapter is not locked out by the PRL switch, it
will be automatically reset via special commands sent over the
communication link.
Important: Do not cycle power to the adapter to clear a fault. All
queued block transfer instructions will be lost.
Remote I/O Wiring
The remote I/O wiring termination is made to a plug-in connector on
the front of the adapter module. Refer to Chapter 2 for information
on wiring the connector.
Power Wiring
Connections are provided for connecting the required 24V dc power
to the front of the module. The power wiring can be daisy-chained to
the terminal base unit located next to the adapter to supply power to
the module installed in that base unit. Wiring information is shown in
Chapter 2.

Multi-position switches are provided for:
•
