Outputs
The TV-UCXPIO48’s universal outputs can be set as analog or binary on their two DIP switches. The expanders’ outputs return to their unconfigured state if they are removed from the program or the program is deleted from the controller. Also, outputs time out and return to their unconfigured or off state after two minutes of inactivity. The unconfigured state results in: · Not running control programs that are due to download · Losing power to the controller, but not the expander NOTE This does not apply to outputs that have been locked in the i-Vu® application.

Analog outputs
Outputs set up as analog can be used for: · 0-10 Vdc devices · 0-20 mA devices
WARNING Do not apply voltage to any output whose DIP switch is set to Analog.

If output controls a… 010 Vdc device 020 mA device

Resistance to ground must be… 500 Ohms minimum 500 Ohms maximum

NOTE The device must share the same ground as the expander.

Binary outputs
The outputs have a built-in relay and provide a dry contact so an external voltage source must be wired to one of the two terminals.
Outputs set up as binary can be used to switch external devices and relays up to 1A, 30 Vac/Vdc.

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.

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
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.

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.

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.

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.

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.

To use an output’s Hand-Auto-Off switch
You can control an output using the Hand-Auto-Off switch.

Set the switch to… Hand
Auto Off

To…
· Turn on a binary output.
· Allow an analog output to be controlled by the AO Hand Override
potentiometer. Let the control program control the output
Turn off the output

The AO Hand Override, located below the Hand-Auto-Off switch, allows you to manually control the output level of an analog output. Place the Hand-Auto-Off switch in the Hand position, then turn the potentiometer counterclockwise to reduce the output, or clockwise to increase the output.

The control program can monitor the status of a Hand-Auto-Off switch and display the status on the control program’s Properties page > I/O Points tab in the i-Vu® interface. The Value of the point monitoring the HandAuto-Off switch shows Off if the switch is set to Auto, and On if the switch is set to Hand or Off.
To monitor the position of the manual Hand-Auto-Off switch
1 Insert a BACnet Binary Input microblock in the control program. 2 On the microblock’s Properties page in the i-Vu® interface, set the I/O Type field to H-A-O Status Feedback. 3 In the Input Number field, type the number of the output you want to monitor.

To monitor expander communication
You can add an analog input in a control program that will provide the communication status of the TV-UCXPIO48. If the input reads a value of 85, the expander is communicating. If the input reads 0, the expander is not communicating. To have the input provide the TV-UCXPIO48’s status, define the following properties for the input. Expander: The expander number you want to read Input Number: 1 Input Type: Special
To replace the TV-UCXPIO48’s fuses
The TV-UCXPIO48 has 2 fuses:

Symptoms of a blown fuse: Expander’s power fuse – The expander’s Pwr LED is not lit.

If you suspect a fuse is blown, remove the fuse as described below, and use a multimeter to check it. If the fuse is blown, try to determine why it blew before you replace it. Check the power wiring polarity of the TV-UCXPIO48 and any other devices that share the power supply. Use the same polarity for all of them.
