UNPACKING AND INSPECTION
1. Examine the hardware immediately for shipping damage.
2. Notify the nearest Bailey Controls 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
This section explains how to configure and install the TAO ter-
mination unit. The required procedures are fuse installation,
dipshunt configuration, installing the termination unit, cable
connection and termination wiring.
Fuse Installation
Two fuses are installed with every TAO termination unit. Verify
that the fuses are installed in fuse clips F1 and F2 (see Figure
for fuse clip locations). Fuse F1 is a 0.5 amp/250 volt fuse
(Bailey Controls part number 194776A15000) used for 24 VDC
I/O power for the AOM module. Fuse F2 is a 3.0 amp/250 volt
fuse (Bailey Controls part number 1948776A13001) used for
24 VDC I/O power for external devices.
Dipshunt Configuration
The dipshunts select the analog output type (voltage or current)
for the field device connected to the termination unit. Each
channel is independent. The TAO termination unit has precut,
installed dipshunts. The dipshunts are in the voltage position
(position one of the dipshunt matched with position V on the PC
board). To select current, remove the dipshunts, rotate the dip-
shunt 180 degrees and insert the dipshunt (position one of the
dipshunt matched with position I on the PC board).
If needed, configure dipshunts by either cutting straps or leav-
ing straps uncut in certain sequences. Cut the dipshunt straps
using a standard shunt cutting tool (Amp Inc. part number
435862-1). Always cut straps completely and ensure they do
not touch adjacent straps. Install the configured dipshunt into
the desired socket (XU1 through XU8) on the TAO circuit
board. Be careful not to bend any pins during insertions. Table
shows how to cut dipshunts one through eight (analog
outputs one through eight respectively). Refer to
