Do Not Use Lead Pencils to Set Dipswitches.
To avoid
contamination of switch contacts that can result in unneces-
sary circuit board malfunction, do not use a lead pencil to set
a dipswitch.
UNPACKING AND INSPECTION
1. Examine the hardware immediately to verify it has not
been damaged in transit.
2. Notify the nearest Elsag Bailey 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/PHYSICAL INSTALLATION
Prior to installation, set the S1 address switch. Configure the
termination unit (TU) or termination module (TM) to output the
digital signals from the DSO to the field devices. Refer to the
appendices at the back of this instruction for configuration
information.
Address Selection Switch (S1)
The DSO can have one of 64 addresses (address 0 to 63) on the
I/O expander bus. This address uniquely identifies the I/O
module to the control module and must be the same as the
address set in the control module configuration (Function
Code (FC) 83 specification S1).
The address is set by the eight position address dipswitch (S1)
shown in Figure
. The six right switch positions (3 through 8)
of S1 set the six bit DSO address. Positions 1 and 2 (Fig.
not used and must remain in the closed position. Table
binary address conversion table for setting address switch S1.
