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: February 3, 2000 • Thermowell RTD sensors require a signal conditioning transmitter to provide a 4-20 mA output to the monitor.
Section 3: Installation 3-11 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.
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 (refer to Figure 3-6): 1. Connect the OEM Potentiometer Wiper to Sensor Input #8. 2. Connect the OEM Potentiometer 0 VDC Common Point to Sensor Common.
Section 3: Installation 3-13 -5 to +5 VDC or -10 to +10 VDC Power Connect the OEM potentiometer to the LTC-MAP Circuit Board, as follows (refer to Figure 3-7): 1. Connect the OEM Potentiometer Wiper to Sensor Input #8. 2. Connect the OEM Potentiometer Center Point to the Sensor Common.
3-14 Section 3: Installation LTC-MAP Power OEM potentiometers that are not powered require power from the LTCMAP’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).
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.
3-16 Section 3: Installation After-Market Use the following procedure to wire an After-Market Tap Position Indicator. 1. Verify that the signal output is one of the following: • - 5V to + +5 VDC • -10 to + 10 VDC, • 0 to +5 VDC, or • 0 to +10 VDC. 2. Connect the signal output to Sensor Input #8. 3. Connect the signal reference to a Sensor Common Terminal. NOTE: Tap Position must be calibrated to operate correctly (see Calibrate Tap Position).
Section 3: Installation 3-17 Wiring the AC Voltage Inputs Connect voltage signals to the designated terminals (Voltage Input #1, #2, #3, #4) on the wiring and installation diagrams. Refer to Figure 3-5 for terminal location. NOTE: The signal specification range for Voltage Inputs #1, #2, #3, and #4 are 0 to 300 Vrms. If your signal input is different, contact Support Services as noted on back cover. Wiring the AC Current Inputs There are two types of current inputs - powered CT and unpowered CT (e.g.
3-18 Section 3: Installation Wiring the Annunciator Outputs Wire the alarms by connecting the alarm activation signal to the Alarm normally opened or Alarm normally closed contacts. Refer to Figure 3-5 for Alarm Contact (Annunciator Output) locations. NOTE: The signal specification range for the Alarm Inputs are 120 VAC @ ¼ HP, 240 VAC @ 10 A, or 150 VDC @ 10 A. If your signal is different, contact Support Services as noted on back cover.
Section 3: Installation 3-19 Wiring the Internal Heater The monitor’s internal heater requires 110 VAC power input. Refer to Figure 3-9 for Heater Terminal locations. WARNING: Do not bridge the heater power terminals to the monitor power supply terminals if DC is used to supply the monitor. The heater is AC only. Wiring Power The LTC-MAP 2130 is factory configured for either 120 VAC or 240 VAC operation per the customer order. Refer to Figure 3-9 for the location of the Power Input Terminals. 1.
3-20 Section 3: Installation Establishing Communications The SAGE 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 LTC-MAP. 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 SAGE .
Section 3: Installation 3-21 Serial Port Communications To establish communications via the front panel serial port: 1. Be sure the modem, if installed, is disconnected at J8. 2. Be sure the SAGE host software is installed on the personal computer. 3. Connect a null modem cable between the front panel serial port and the serial port on the personal computer. See Figure 3-10 for serial port location. 4. From within the SAGE host software, set the serial port rate to 19200 bps.
3-22 Section 3: Installation Modem Communications To establish communications via a modem: 1. If not already installed, mount the modem inside the monitor using the supplied Velcroattachments. 2. Connect the modem per the instructions supplied with it. See Figure 3-11 for modem mounting location and typical connections. 3. Set JP12 on the I/O board to select the modem power supply. Refer to Modem Power Supply Configuration earlier in this section. 4.
