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.

3-10 Section 3: Installation

Wiring the Sensors

Refer to Table 1-1 for a list of sensors available for use with the
LTC-MAP 2130 Monitor. Detailed installation information for each sensor is
provided in the referenced documentation.

Some general notes to consider during sensor selection and installation:

• Thermowell RTD sensors require a signal conditioning transmitter to
provide a 4-20 mA output to the monitor.

• Figure 3-4 provides Sensor and Input Connection locations on the I/O
board.

• We recommend using #18 AWG shielded, twisted pair wire for sensor
input connections to the I/O board, unless stated otherwise in the
documentation provided with the sensor. Use of shielded twisted pair
improves noise immunity; the shield should be grounded at one end
only.

February 3, 2000 70055MP Revision D

Section 3: Installation 3-11

Wiring a Tap Position Indicator

OEM Potentiometer s

The OEM potentiometer is a voltage divider containing a resistor string.
Each position on the string represents a tap position. In the examples in
this Section, the potentiometers have thirty three positions containing thirty
two 40-ohm resistors. The actual number of positions and number and
values of resistors may be different on your potentiometer.

The power supplied to the OEM potentiometer depends on the utility. The
variations include:

• -5 to +5 VDC or -10 to +10 VDC.

• 0 to +5 VDC or 0 to +10 VDC.

• No voltage (connect with LTC -MAP power).

Determine the voltage across your potentiometer and follow the
appropriate wiring instructions.

In general, two signals are utilized between the OEM potentiometer and the
LTC-MAP. The signal is a linearly varying DC voltage (+10 V maximum).

For proper tap position recording by the LTC -MAP, the linearly varying DC
voltage from the OEM potentiometer must have a uniform increment for
each tap position. For example, a potentiometer used for a 33 tap device
(16 lower, 16 raise, and neutral) with a 10 Volt drop across the entire bridge
must show a 10V/32 = 0.3125 V change per tap step on the potentiometer
wiper.

70055MP Revision D February 3, 2000

3-12 Section 3: Installation

0 to +5 VDC or 0 to +10 VDC Power

Connect the OEM potentiometer to the LTC -MAP Circuit Board, as follows

Figure 3-7: Typical OEM Potentiometer with -5 to +5 VDC Power

70055MP Revision D February 3, 2000

3-14 Section 3: Installation

LTC-MAP Power

OEM potentiometers that are not powered require power from the LTC ­MAP’s 24 VDC Sensor Power Supply. To use the LTC -MAP supply, you
must:

• Select a Voltage Drop Resistor (Rd).

• Connect the Power Supply wires to the OEM Potentiometer.

• Connect the wires at the Monitor Circuit board.

In order to use this power, you must first calculate the value of the required
voltage drop resistor (Rd). The voltage drop resistor limits the current and
voltage across the potentiometer (see Figure 3-8).

Figure 3-8: Typical OEM Potentiometer Powered by LTC-MAP

To calculate Rd:

1. Determine the value and number of resistors in the potentiometer.

NOTE: LTC -MAP can accommodate any value or number of tap
position resistors.

2. Calculate the String Resistance (Rs) where:
Rs = (Resistor Value) x (Number of Resistors).

February 3, 2000 70055MP Revision D

Section 3: Installation 3-15

3. Calculate the Voltage Drop Resistor value (Rd):
Rd = Rs x 1.4.

4. Select a voltage drop resistor as follows:
Resistance: first standard value greater than the Rd.
Power rating: 2 watts.
Tolerance: 5% or less

As an example, consider a potentiometer with thirty-two 40 ohm

resistors. The calculated string resistance would be:
Rs = (40 ohms) x (32 Resistors) - 1280 ohms.
And
Rd = Rs x 1.4 = 1280 x 1.4 = 1792 ohms.
The next standard resistor value greater than 1792 is 1800 ohms.
Therefore, the selected voltage drop resistor should be an 1800 ohm,
5%, 2 watt resistor.

Connect the wires to the OEM Potentiometer as follows:

1. Connect the designated positive point lead to the OEM Potentiometer
Positive Point.

2. Connect the designated common point lead to the OEM Potentiometer
Common Point.

3. Connect the designated wiper lead to the OEM Potentiometer Wiper.

Connect the wires to the circuit board as follows:

1. Connect one end of the Voltage Drop Resistor (Vd) to a sensor power
supply terminal.

2. Connect the positive point lead to the other end of the Voltage Drop
Resistor (Vd).

3. Connect the common point lead to the designated Sensor Common
terminal.

4. Connect the wiper lead to Sensor Input #8.

NOTE: Tap Position must be calibrated to operate correctly (see Calibrate
Tap Position).

CAUTION: The positive lead must be connected to Sensor Input #5 and the
negative lead to Sensor Common. Failure to comply can damage the LTC ­MAP.

70055MP Revision D February 3, 2000

The LTC -MAP 2130 monitor collects output data from the Control Isolator at
the digital inputs. (See Figure 3-4 for Control Isolator Input terminal
locations.)

NOTE: Refer to Document No. 70062MP for specific information on
the Control Isolator, Part No. 40041MP.

1. Mount the Control Isolator(s) per the guidelines provided in the
documentation provided with the Control Isolator.

NOTE: The control Isolators are provided with a 10 foot cable;
therefore, when selecting a mounting location, be sure it is within 10
feet of the monitor.

2. Connect the output cable of the Control Isolator to the First Control
Isolator Input (digital channels 1-8) as designated on the wiring and
installation diagrams.

3. If there is a second Control isolator installed, connect the output cable
of the Control Isolator to the Second Control Isolator Input (digital
channels 9-16) as designated on the wiring and installation diagrams.
