COMMUNICATION ARRANGEMENTS
Communication Type
Single Device RS232C
Description
A direct connection to an RS-232C compatible device where the IQ-2000 acts as a slave.
A COM 21 Communicatton Card plugs directly onto the Processor Module.
Communication to
any computer A Local Area Network, INCOM” is formed by 2 or more IQ-2000s connecting to a Trans-
later Box. The Translator Box is a slave to the main computer. In this arrangement the
COM 22 Communication Card is plugged into the Processor Module of each IQ-2000.
These cards are wired together using a shared non-shielded twisted pair to form a local
area network. The twisted pair is wired to a Translator Box containing a COM 23 Com-
munication Card which provides an RS-232C port.
Communication to an IBM- A Local Area Network, INCOM IS formed by 2 or more IQ-2000s connecting to a per-
compatible personal computer sonal computer via a shared non-shielded twisted pair of wires. The personal computer
acts as a master. In this arrangement the COM 22 Commumcation Card plugs into each
Processor Module. A COM 25 Communlcatlon Card is used in an expansion slot of the
personal computer.

remain stored through power outages or until new program-
mung entries change the values.
The IQ-2000 is factory-shipped in any of the following ways:
Mounted in the low-voltage compartment of the
Ampgard”‘ enclosure
For Installation by an original equipment manufacturer
In a new motor command system
For Installation by the Westmghouse Engineering Serv-
ices Department into an existing motor starter
For installation by an end user in a motor starter
1.1 Features and Options-A list of features and benefits
is given in Table l.A. Since the IQ-2000 is a standardized pack-
age, there are very few optrons. Those currently available are:
RTD Module optron, whrch is required if resistance tem-
perature devices are used to monrtor motor and load or
motor bearing temperatures. The RTD Module is offered
for lo-ohm, loo-ohm, and 120-ohm applications.
Ground Fault Transformer option, which provides input
current signals. (Its ratio is always 50:5.)
Potential Transformers optron, whrch provides incom-
rng AC ltne phase and level Information.
Communication options, whrch provrde communication
of motor data to a remote device such as a computer or
programmable controller. The communication options are
described in more detail in publication number TD-11-730.
In all cases a Communication Card will be installed in-
srde the IQ-2000. Table 1.B lists and describes the 3 types
of communrcatron arrangements available.
1.2 Specifications - The specifications for the IQ-2000
motor command system are lrsted in Table 1.C.
1.3 Hardware Familiarization - The purpose of this Para-
graph is to familiarize the user with the main hardware
features of the IQ-2000. A complete description of the Oper-
ator Panel and the functions of each pushbutton IS given in
Chapter 4.
The IQ-2000 mounts in an optional enclosure, as shown in
the typical installation of Figure 1.2. Observe the Figure and
note the following explanation keyed to the callouts of the
Figure:
1. The enclosure is a Type 1
2. Cable connecting the Processor Chassis to the Oper-
ator Panel
3. Terminal block TB-A
4. Terminal block TB-B
5. Terminal block TB-R for connections to optional RTD
Module
AC line fuse
Terminal block TB-P for the Pl, P2, and P3 AC line
connections
Additional terminal block. When the IQ-2000 is in-
stalled by Westinghouse, this is assigned the desig-
nation TB. The TB terminal block IS not part of the
IQ-2000 hardware.
The various components of the 02000’s Processor Chas-
SIS are shown rn Figure 1-3. Observe the Figure and note the
following:
l The front cover of the IQ-2000 consists of a hinged ac-
cess door. (A screw secures it to the Chassis.)
