ABB IMASI23 module ASI
IntroductionThis section explains what to do before putting the IMASI23
module (ASI) into operation. Do not proceed with the installa tion and operation until you read, understand and do the steps
in the order in which they appear. Refer to Appendix A for ter mination unit wiring instructions. Refer to Section 4 to config ure the IMASI23 module.
Special Handling
NOTE: Always use the ABB Automation field static kit (part number
1948385A1), consisting of two wrist straps, ground cord assembly, alligator
clip, and static dissipating work surface when working with static sensitive
devices. The kit is designed to connect the technician and the static dissipating
work surface to the same ground point to prevent damage to the static sensi tive devices by electrostatic discharge.
Use the static grounding wrist strap when installing and
removing modules. Static discharge may damage static sensi tive devices on modules in a cabinet. Use grounded equipment
and static safe practices when working with static sensitive
devices.
1. Use Static Shielding Bag. Keep the module in its static
shielding bag until you are ready to install it in the system.
Save the bag for future use.
2. Ground Bags before Opening. Before opening a bag con taining an assembly with static sensitive devices, touch it to
the equipment housing or ground to equalize charges.
3. Avoid Touching Circuitry. Handle assemblies by the
edges; avoid touching the circuitry.
4. Avoid Partial Connection of Static Sensitive Devices.
Verify that all devices connected to the modules are properly
grounded before using them.

6. Use an Antistatic Field Service Vacuum. Remove dust
from the cards if necessary.
7. Use a Grounded Wrist Strap. Connect the wrist strap to
the appropriate grounding plug.
8. 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 ABB Automation 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 Installation
NOTE: Refer to Appendix C for information about replacing an IMASI03 mod ule or Appendix B for an IMASI13 with an IMASI23 module.
Before applying power to the ASI module, make these checks:
1. Check that the module address is set correctly.
2. Check that the jumpers on the module are set correctly.
3. Be sure the dipshunts in the module mounting unit's I/O
expander bus are installed correctly.
4. Check that the jumpers on the termination units are set
correctly.
5. Verify I/O cabling connections
6. Verify there is sufficient logic and field power for the modules in the module mounting unit.
Address Selection Switch (S1)
The ASI module must have an address to communicate with
the controller. The ASI module can have any one of 64
addresses (address 0 to 63) on the I/O expander bus. This
address identifies the ASI module to the controller and must be
the same as the address set in the controller configuration data
(FCs 215 and 216, specification S1).
Set the address with the eight position address dipswitch S1
(Fig. 3-1). The six right switch positions (three through eight) of
S1 set the six-bit address. Positions one and two must remain
closed (set to zero) for normal operation (Fig. 3-2).
