Unpacking and Inspection
1. Examine the hardware immediately to verify it has not
been damaged in transit.
2. Notify the nearest ABB sales office of any such damage.
3. File a claim for any damage with the transportation com-
pany that handled the shipment.
4. Use the original packing material and container to store
the hardware.
5. Store the hardware in an environment of good air quality,
free from temperature and moisture extremes.
Setup and Physical Installation
Prior to installation, set the module dipswitches and install
jumpers to configure the I/O modules. The termination unit
must also be configured to accept the field device signals and
output the I/O module signals to the process.
Address Selection Switch (S1)
The I/O module can have one of 64 addresses (address 0 to 63)
on the I/O expander bus. This address uniquely identifies the
module to the controller and must be the same as the address
set in the controller configuration (FC 79, specification S1).
The address is set by the eight position address dipswitch (S1)
shown in Figure 3-1. The six right switch positions (three
through eight) of S1 set the six-bit address. Positions one and
two are not used and must remain in the closed position
(Fig. 3-2). Table
ting for S1.
