SECTION 2 - INSTALLATION
INTRODUCTION
This section explains how to install the NTAI06 Analog Slave
Input Termination Unit. For proper operation, read, under-
stand, and complete the steps in the order they appear before
using the NTAI06.
SPECIAL H ANDLING
Observe these steps when handling electronic circuitry:
NOTE: Always use the Bailey Controls Field Static Kit (part number
1948385A1 - consisting of two wrist straps, ground cord assembly,
alligator clip, and static dissipating work surface) when working with
modules. The kit is designed to connect the technician and the static
dissipating work surface to the same ground point to prevent dam-
age to the modules by electrostatic discharge.
Use the static grounding wrist strap when installing and
removing modules. Static discharge may damage MOS devices
on modules in the cabinet. Use grounded equipment and static
safe practices when working with modules.
1. Use Antistatic Bag. Keep the modules in the antistatic
bag until you are ready to install them in the system. Save the
bag for future use.
2. Ground Bags Before Opening. Before opening a bag con-
taining an assembly with CMOS devices, touch it to the equip-
ment housing or ground to equalize charges.
3. Avoid Touching Circuitry. Handle assemblies by the
edges; avoid touching the circuitry.
4. Avoid Partial Connection of CMOS Device. Verify that all
devices connected to the modules are properly grounded before
using them.
5. Ground Test Equipment.
6. Use an Antistatic Field Service Vacuum to remove dust
from the module if necessary.
7. Use a Grounded Wrist Strap. Connect the wrist strap to
the appropriate grounding plug on the power entry panel. The
grounding plug on the power entry panel is connected to the
cabinet chassis ground.

INSTALLATION
UNPACKING AND INSPECTION
2 - 2 I-E96-440A
®
UNPACKING AND INSPECTION
These are steps to follow for general handling:
1. Examine the unit to make sure that no damage has
occurred in transit.
2. Notify the nearest Bailey Controls sales office of any
damage.
3. File a claim for any damage with the shipping company
that handled the shipment.
4. Use the original packing material or container to store the
unit.
5. Store the unit in a place with clean air; free of extremes of
temperature and humidity.
SETUP/INSTALLATION
This section explains how to configure and install the NTAI06.
The required procedures are: setting the jumpers, mounting
the termination unit to the field termination panel and con-
necting the field wiring and termination cables. There are two
revisions of the NTAI06. Revision A hardware (assembly num-
ber 6639364A1) has a fuse F17. Revision B hardware (assem-
bly number 6639364B1) has additional filter capacitors.
Each NTAI06 termination unit has a pair of resistance temper-
ature detectors (RTDs) which measure the local temperature of
the field wire to terminal block connection. This temperature is
used to compensate for the cold junction effect on thermocou-
ple inputs.
When using the built-in cold junction reference, the termina-
tion unit cover should be in place. The cover encloses both the
terminal blocks and the RTDs. It helps maintain the same tem-
perature around the terminal blocks and the RTDs. Maintain-
ing both at the same temperature allows maximum accuracy
for thermocouple inputs. Always keep the cover on during
operation when thermocouple inputs are connected. Refer to
Jumper Settings.
Fuses
Fuses F1 to F16 are shipped installed in fuse clips F1 to F16.
They are 31.25 milliamp, 125 volt fuses, (Bailey part number
1945820A10310). Revision A (assembly number 6639364A1)
also has one fuse F17. It is a 2.0 amp, 250 volt fuse, (Bailey
part number 1948182A32001). The fuse is shipped installed
on the revision A assembly termination units in fuse clip F17.

INSTALLATION
SETUP/INSTALLATION
I-E96-440A 2 - 3
Jumper Settings
Jumpers on the termination unit configure the 16 analog
inputs. See Figure 2-1 and 2-2 for jumper locations and termi-
nal assignments.
Jumpers on the termination unit configure each of the 16 ana-
log inputs to match the signal type of the device connected to
that input. Each channel is independent. The selection
includes: voltage or current input, differential or single ended
voltage, system externally powered, four to 20 milliamp, or 3
wire RTD inputs. Set the jumpers according to the tables in
this section. To enable the input type, short the appropriate
pins together with a jumper.
Figure 2-3 shows a typical input circuit for the NTAI06.
Table 2-1 lists the jumper configurations for the TU. Table 2-2
lists the devices that can connect to the TU. Table 2-3
describes the input types. Jumpers used by each input chan-
nel are listed with the field termination example later in this
section.

Table 2-3. NTAI06 Input Type Descriptions
Input Type Input Description
Single ended voltage This jumper configuration connects the minus (-) input terminal to I/O COM on the
NTAI06. The IMASI03 measures the voltage at the plus (+) input terminal with
respect to the I/O COM terminal. No connection to the C terminal is necessary.
Differential voltage This jumper configuration connects the plus (+) and minus (-) inputs directly to
IMASI03 differential input. Channel to channel and channel to system common signal
isolation is achieved for all voltage input types, including high level voltage, millivolts
and thermocouples. No connection to the C terminal is necessary.
System powered
4 - 20 mA This jumper configuration connects the plus (+) input terminal to system +24 VDC through a fuse on the NTAI06. The minus (-) input terminal connects to a precision
resistor that generates a single ended voltage (1-5 V) for the IMASI03 to measure.
No connection to the C terminal is necessary. INFI 90 must have +24 V (system
power) installed.
External powered
4 - 20 mA This jumper configuration connects the plus (+) input terminal to one end of a precision resistor and the minus (-) input to the other end of the same precision
resistor in the NTAI06. An isolated 1-5 V is generated for the IMASI03 to measure.
No connection to the C terminal is necessary.
3-wire RTD This jumper configuration connects the plus (+) and minus (-) inputs and the COM
input directly to IMASI03 three-wire input. Channel to channel and channel to system
signal isolation is maintained. The two common leads of the RTD element should be
connected across the plus (+) and common (C) terminals, and the third lead should
be connected to the minus (-) terminal.

The NKAS01 and NKAS11 are round, shielded cables that con-
nect the TU to the IMASI03 slave module. The NKAS01 cable
has a PVC jacket and is rated for 80 degrees celsius at 300 volt
(UL rated type CL2). The NKAS11 cable has a non-PVC jacket
and is rated for 90 degrees celsius at 300 volt (UL rated type
PLTC). See Figure 2-5 for the cable connections from the termi-
nation unit to the slave module. Table 2-4 lists the NTAI06
cable applications.
Figure 2-4. Installation for Revision A and B Hardware NTAI06
CAUTION Remove modules (slave or termination) from their assigned slots before installing a cable to that slot. Failure to do so
could result in damage to the module or station.
ATTENTION
Retirer les modules (asservi ou carte de raccordement) de leur
position assignée avant d'installer un câble à cette position.
Des dommages au module ou au poste pourraient résulter d'un
manquement à cette procédure.
