Section 1: Introduction
Product Overview
The LTC-MAP 2130 Monitor (Figure 1-1) is an on-line maintenance
action planner (MAP) for load tap changers (LTC). It continuously
monitors performance data from various types of sensors, such as
temperature and current. It stores this data in non-volatile memory for
downloading to a personal computer.
Figure 1-1: LTC -MAP 2130 Monitor
70055MP Revision D February 3, 2000
1-2 Section 1: Introduction
LTC-MAP 2130 Monitor is a multi -input data storage and analysis
system. Each system features:
• Seventeen (17) analog input channels.
• Sixteen (16) digital input channels (via optional Control Isolator).
• One (1) serial port/modem line.
• Two annunciator relay outputs (form C contacts).
LTC-MAP 2130 uses state of the art technology to process, analyze,
and store data into a configurable profile. A built-in microprocessor
compares, computes, and relates stored data to set parameters.
Alarms are generated when data levels exceed the set parameters.
NOTE: Parameters are set via the SAGE host software package.
Refer to the SAGE Product Manual, Part No. 70057MP, for details
on parameter configuration and data retrieval and analysis.
Data profiles and alarm events are stored in non-volatile randomaccess memory. The stored information is then downloaded to a
personal computer, either directly through the serial port or via an
optional modem. The SAGE host software package allows data
retrieval and analysis.

Typical Application
A transformer utilizing an LTC-MAP 2130 monitor is illustrated in Figure
1-2. The monitor is mounted on the transformer. Analog sensors
mounted on the transformer are connected to the monitor. Refer to the
example typical wiring diagram in Section 3 to determine specific
sensor input connections.
Figure 1-2: Typical LTC -MAP 2130 Application
70055MP Revision D February 3, 2000
1-8 Section 1: Introduction
A typical system may include several monitors, one for each
transformer at the site, multiplexed together. The multiplexer is
typically located at the on-site substation. (See Figure 1-3). Data from
all monitors on site may then be downloaded to a remote personal
computer (PC). SAGE host software installed on the PC allows for
data retrieval and analysis.

Front Cover Layout
There are three indicator lights on the front cover of the LTC-MAP 2130
Monitor (see Figure 2-1):
• The yellow POWER indicator illuminates whenever the monitor is
receiving power.
• The red ALARM1 indicator illuminates whenever a configured
contact relay alarm is activated.
• The red ALARM2 indicator illuminates whenever a configured
contact relay alarm is activated.
The fasteners on the right side of the front cover allow access to the
inside face panel of the monitor.

Serial Port
CAUTION: The serial port and the modem cannot function
simultaneously. When using the serial port for communications, the
internal modem (if installed) must be disconnected at JP8; otherwise
the serial port will not function.
The serial port is a 9-pin male DB-9 connector. This port allows direct

and a portable computer for data transfer. Data transfer rate is
19.2 kbps.
The serial port does not support dumb terminal operation. In order for
communications to take place:
• A null modem cable must be installed between the monitor serial
port and personal computer serial port.
• SAGE host software must be installed on the personal computer.
NOTE: A null modem cable is available (Part No. 10101MP ).
