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
Before installation, set the module S1 address switch and
install jumpers to configure the digital inputs. Configure the
termination unit (TU) or termination module (TM) to accept the
field device signals.
Address Selection Switch (S1)
The DSI 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 84 specification S1).
The address is set by an eight position address dipswitch (S1),
shown in Figure
. The six right switch positions (3 through
8) of S1 set the six bit DSI address. Positions 1 and 2 are not
used and must remain in the closed position (Fig.
). Table
is a binary address conversion table for setting S1.
Digital Input Jumper Settings
The IMDSI13 and IMDSI14 modules have fixed configurations,
thus no jumper settings are required. The IMDSI12 (24/48/
125 VDC or 120 VAC) module requires jumper settings for
both the working voltage and the DC or AC mode selections.
The IMDSI15 (125 VDC/120 VAC) module requires jumper
settings for the DC or AC mode selection.
