To avoid damage to the expander, use a voltmeter to verify there is no voltage on the + and - terminals before setting the DIP switch to Analog. 6 Turn on the TV-UCXPIO48's power. See Troubleshooting inputs and outputs (page 22). TruVuTM I/O Expanders Installation and Start-up Guide Carrier Proprietary and Confidential 14 ©2023 Carrier. All rights reserved. To adjust input and output properties An input or output must be assigned to its corresponding point in the control program. This is typically done when the control program is created, but you can adjust the settings at the time of installation in the i-Vu® interface. 1 In the i-Vu® User tab, select the equipment controlled by the TV-UCXPIO48. 2 On the Properties page, select the I/O Points tab. 3 For each point, type the expander's rotary switch address in the Exp field and the number of the expander's corresponding input or output in the Num field. EXAMPLE If UO-01 on the TV-UCXPIO48 (which has a rotary switch address of 1) is used for the point Fan S/S, enter 1:1 in the Exp:Num column for Fan S/S. NOTE Do not assign the same output number to more than one point. 4 Enter the appropriate values for each input and output in the remaining columns. See Input values, Output values, Resolution values and Offset/Polarity values below. CAUTION Do not assign two input microblocks to the same physical input using Dry Contact in one and Binary Input in the other. This results in faulty behavior. 5 If you have not performed the initial download to the attached controller, you must download now to verify inputs and outputs. 6 To verify each input's operation, force each sensor to a known value, then compare it to the Value shown on the Properties page on the I/O Points tab. 7 To verify each output's operation, lock each output to a known condition on the I/O Points tab, then verify that the equipment operates correctly. See Troubleshooting inputs and outputs (page 22) .

This results in faulty behavior. 5 1 The sensor reads a value and sends a corresponding signal (Volt or mA) to the TV-UCXPIO48's physical input. The Analog Input microblock uses the Min and Max values to linearly translate the signal into the engineering value used in subsequent control logic. For example, set Min to 0 and Max to 10 for a 420 mA sensor that measures velocity from 0.0 to 10.0 inches/second so that when the input reads 4 mA, the microblock outputs a value of 0. Similarly, when the input reads 8 mA, the microblock outputs a value of 2.5. 2 You can set up a custom translation table on the driver's Custom Translation Tables pages in the i-Vu® interface. 3 The control program must have one Pulse to Analog Input microblock for each pulse counting input. 4 To improve the accuracy for RTD sensors used with long cables, see Offset/Polarity values (page 19). 5 Binary Input and Dry Contact input types are not interchangeable. Setting an input to Dry Contact applies a wetting voltage to sense a dry contact. Setting an input to Binary Input will not apply a wetting voltage.

Engineering values associated with 4 mA (Min) and 20 mA (Max) 1 Relay Relay/Triac N/A N/A Output 1 The Analog Output microblock uses the Min and Max values to linearly translate its incoming value into a physical output signal (Volt or mA) sent from the TV-UCXPIO48 to an actuator. For example, set Min to 0 and Max to 100 for an Analog Output microblock that receives a 0 to 100% open signal from a PID microblock and that controls a 010 Vdc actuator so that when the PID signal is 100%, the TV-UCXPIO48 output is 10 Vdc. Similarly, when the PID signal is 50%, the TV-UCXPIO48 output is 5 Vdc. TruVuTM I/O Expanders Installation and Start-up Guide Carrier Proprietary and Confidential 17 ©2023 Carrier. All rights reserved. Resolution values Resolution is not particular to a type of input or output, but the driver handles analog and binary inputs and outputs differently. To set these values appropriately, you should understand how the driver uses them. Resolution Notes Analog Input (BAI) Analog Output (BAO) The driver rounds the microblock's present value according to the resolution. EXAMPLE If the calculated present value is 13.789 and you set the Resolution to 0.1, the control program uses 13.8 for any calculations downstream from the microblock. The driver rounds the wire input value to the microblock before performing any scaling calculations. EXAMPLE If the wire input value is 13.789 and you set the Resolution to 0.1, the microblock uses 13.8 for any scaling calculations. TruVuTM I/O Expanders Installation and Start-up Guide Carrier Proprietary and Confidential 18 ©2023 Carrier. All rights reserved. Offset/Polarity values Offset/Polarity is not particular to a type of input or output, but the driver handles analog and binary inputs and outputs differently. To set these values appropriately, you should understand how the driver uses them. Offset/Polarity Analog Input (BAI) Notes Offset value (positive or negative) adds a fine adjustment to a sensor reading after all scaling for calibration. EXAMPLE If a sensor reads 74.9°F when the actual measured value is 73.6°F, enter an Offset of 1.3 to calibrate the sensor to the measured value. RTD inputs require either sensor calibration or an estimated offset correction for wiring resistance. Cable length and size affects RTD sensor accuracy. Use the following information for a 100 ft. (30.48 m) cable as a guideline for entering an offset. For shorter cable, scale the offset linearly. For example, for a 50 ft. cable, use half the offset shown below. RTD sensor Offset for 100 ft. (30.48 m) cable 22 AWG 18 AWG Platinum 1kOhm at 32°F (0°C) (0.00375 -1.5 TCR) -0.59 Nickel-iron 1kOhm at 70°F (21°C) -1.1 -0.43 Platinum TS-8000 1kOhm at -1.5 32°F (0°C) (0.00385 TCR) -0.59 Balco (nickel-iron) TS8000 1kOhm -1.4 at 70°F (21°C) -0.56 Cable resistance for signal and 3.1 ground wires (ohms) 1.24 Analog Output (BAO) You can use the Offset value (positive or negative) to calibrate an output, but you generally do not need to. If used, the driver adds the offset value to the wire input value before performing any scaling calculations to determine the TV-UCXPIO48's output. Binary Input (BBI) Polarity determines the microblock's present value when no signal is received from the equipment. When no signal is received from the equipment, if Polarity is set to: normal--present value is off reversed--present value is on Binary Output (BBO) Polarity determines the TV-UCXPIO48's output based on the control program's signal to the microblock. When the control program's signal to the microblock is on, if Polarity is set to: normal--output is on reversed--output is off NOTE Regardless of Polarity, the output will be off if the TV-UCXPIO48 loses power.
