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.

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 SAGEä host software package.  
Refer to the SAGEä 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 random-  
access memory. The stored information is then downloaded to a  
personal computer, either directly through the serial port or via an  
optional modem. The SAGEä host software package allows data  
retrieval and analysis.

Communications  
The SAGEä host software installed on a personal computer allows for  
data retrieval and analysis. Communications with the LTC-MAP 2130  
must be established in order to download data to the PC or upload  
configuration information to the terminal. Communication between the  
PC and the monitor can be established:  
·
Directly via the front panel serial port and a null modem cable  
to a personal computer running the SAGEä host software.  
NOTE: SAGEä host software must be installed on the PC for  
proper communication to take place. The front panel serial  
port does not support dumb terminal operation.  
·
Over phone lines using an optional modem installed inside the  
monitor.  
·
Over phone lines via a phone multiplexer installed in the  
control house and connected to several LTC-MAP 2130  
monitors. Refer to Document No. 70061MP for detailed  
information on the phone multiplexers available from Reuter-  
Stokes, Inc.  
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 J8; otherwise  
the serial port will not function.

This Section includes procedures for installation, configuration, wiring,  
setting up communications, and initial start-up of the LTC-MAP 2130  
Monitor.  
Selecting a Location  
The LTC-MAP 2130 is enclosed in a weatherproof stainless steel box that  
can be mounted indoors or outdoors. When selecting a mounting location  
for the monitor, verify that:  
·
The mounting surface is able to support a minimum of 25 pounds (11.3  
kg).  
·
The mounting surface allows ample space for mounting the stainless  
steel box and allows for a 12-inch (305 mm) door clearance (see Figure  
3-1).  
·
·
·
·
Sensors are located nearby to minimize cable length.  
Wiring and cables can access the monitor gland plate.  
The face panel display is at a readable level.  
An operating temperature of 0 ºC to +60 ºC (+32 ºF to +140 ºF) can be  
maintained at the monitor location.  
NOTE: With the heater option installed, an operating temperature of  
-40 ºC to +º60 C (-40 ºF to +140 ºF) must be maintained at the  
monitor location.  
CAUTION: Select a mounting location that assures an operating  
temperature of 0 ºC to +60 ºC (+32 ºF to +140 ºF), otherwise system operation  
could be interrupted.

Cable Installation  
After securely mounting the LTC-MAP 2130 monitor, route the input and  
output cables back to the gland plate.  
CAUTION: Do not apply power to the LTC-MAP 2130 until all input and  
output cables are connected.  
The removable gland plate on the bottom of the LTC-MAP 2130 Monitor has  
pre-punched conduit holes (see Figure 3-2) and strain relief cable  
connectors. Weep holes are provided to allow drainage of excess  
moisture.  
Additional holes can be drilled into the gland plate if required. Remove the  
plate by removing the two nuts and washers securing it to the monitor. The  
nuts are accessed from inside the monitor.  
CAUTION: Do not drill additional holes into the gland plate while it is installed  
on the monitor. Metal chips can damage the circuit boards.

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.

Wiring a Tap Position Indicator  
OEM Potentiometers  
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.

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 (R ).  
d
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 (R ). The voltage drop resistor limits the current and  
d
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).

Download from Www.Somanuals.com. All Manuals Search And Download.  
Section 3: Installation  
3. Calculate the Voltage Drop Resistor value (Rd):  
3-15  
R = R x 1.4.  
d
s
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:  
R = (40 ohms) x (32 Resistors) - 1280 ohms.  
s
And  
R = R x 1.4 = 1280 x 1.4 = 1792 ohms.  
d
s
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 (V ) to a sensor power  
d
supply terminal.  
2. Connect the positive point lead to the other end of the Voltage Drop  
Resistor (V ).  
d
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.
