TERMINATION UNIT CONFIGURATION (NTCS02)
INTRODUCTION
A - 2
I-E96-207A
®
For example, analog input number 1 field wiring is attached to
screw terminals 9 (-) and 10 (+) of terminal block number 1.
Dipshunt XU1 conditions analog input number 1. If analog
input number 1 is a powered 4-20 mA input, XU1 is configured
as follows: straps 2, 4, and 5 are cut, straps 1, 3, 6, 7 and 8 are
left intact. The dipshunt is now configured for a power 4-10 mA
input and it matches the input from the field wiring. Module
configurations for other types of inputs are given in the figures
and tables in this section.
Mounting
The TCS mounts on the field termination panel (FTP) in the
INFI 90/Network 90 cabinet by two screws in the panel mount-
ing slots. Since it can be mounted on either the left or right
side, it is VERY IMPORTANT to observe the orientation of the
dipshunts and sockets for the location of pin number 1.
Figure
shows the Termination Unit (NTCS02). Table
lists the dipshunt configurations and Table
lists the termi-
nal block assignments.
Configuring Dipshunts
There are two methods for breaking desired dipshunt straps:
1. With dipshunt in socket: use an Amp, Inc. Tool P/N 435862-1
or equivalent and push down in the middle of the strap.
2. With dipshunt out of socket, turn it over with its leads up
and break the desired strap as in step 1. Or lay it on a piece of
1/4 in. square key stock or similar material to support the dip-
shunt while breaking straps.
Use either method, but always ensure that the strap is completely
broken and that shorts to adjacent straps have not occurred.
Dipshunt Assignments
NOTES:
1.
Analog output mode (current or voltage) is dependent on the
COM configuration. The outputs can be both voltage, both current, or
one voltage and one current. Refer to Table
for the configurations.
2.
For schematic configurations refer to Figures
,
and
3.
XU8 provides a position feedback for electric control drives.
Analog input 3 provides the feedback to the bypass SAC cabled to
P2 on the TCS. Analog input 4 provides the feedback to the bypass
SAC cabled to P3 on the TCS.
4.
The feedback signals are used only for electric control drives
and should not be connected if signals other than drive position are
used on these inputs. The signal settings on the SAC must match
the setup of dipshunt XU8.
