Battery: Back-up, First Use, Installation, and Replacement
Back-up
In order to preserve back-up values for RTC and system data in the event of power off, the battery must be connected.
First Use
The battery is protected by the PLC’s bottom and inner door.
The battery is supplied installed inside the unit, with a plastic tab preventing contact. Pull out this tab before using the device.
Battery Installation and Replacement

• **** Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing the battery.

Caution

• To preserve back-up values for RTC and system data during battery replacement, the controller must be powered.
• Note that disconnecting the battery halts the preservation of back-up values and causes them to be deleted.

1. Open the bottom and inner doors.
2. If there is a battery present, remove it.
3. Slide the battery into place.

• **** Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing the microSD card.

1. To install the microSD card slide it into the slot as shown in the accompanying figure, until the card clicks into place.
2. To remove the card, press it into its slot lightly, the spring ejects it.

Wiring

• This equipment is designed to operate only at SELV/PELV/Class 2/Limited Power environments.
• All power supplies in the system must include double insulation. Power supply outputs must be rated as SELV/PELV/Class 2/Limited Power.
• Do not connect either the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to device’s 0V point.
• Do not touch live wires.
• All wiring activities should be performed while power is OFF.
• Use over-current protection, such as a fuse or circuit breaker, to avoid excessive currents into the power supply connection point.
• Unused points should not be connected (unless otherwise specified). Ignoring this directive may damage the device.
• Double-check all wiring before turning on the power supply.

Caution

• To avoid damaging the wire, do not exceed a maximum torque of:
  – All terminal blocks except T42 outputs’ terminal block: 0.5 N·m (4.4 in-lb).
  – T42 outputs’ terminal block (with smaller pitch): 0.2 N·m (1.8 in-lb).

• Do not use tin, solder, or any substance on stripped wire that might cause the wire strand to break.

• Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm² –3.31 mm²)

1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.

Wiring Guidelines
In order to ensure that the device will operate properly and to avoid electromagnetic interference:

• Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.

• Use wires that are properly sized for the load.

• Use shielded twisted pair cables for wiring High Speed and Analog I/O signals.
  Use shielded cables for wiring thermocouple and RTD signals.
  In either case, do not use the cable shield as a signal common / return path.

• Route each I/O signal with its own dedicated common wire. Connect common wires at their respective common (CM) points at the controller.

• Individually connect each 0V point and each common (CM) point in the system to the power supply 0V terminal, unless otherwise specified.

•  Individually connect each functional ground point ( ) to the earth of the system (preferably to the metal cabinet chassis).
  Use the shortest and thickest wires possible: less than 1m (3.3’) in length, minimum thickness 14 AWG (2 mm2 ).

•  Connect the power supply 0V to the earth of the system.

• Earthing the cables’ shield:
  ➢ Connect the cable shield to the earth of the system (preferably to the metal cabinet chassis).
  Note that the shield must be connected only at one end of the cable; it is recommended to earth the shield at the PLC-side.
  ➢ Keep shield connections as short as possible.
  ➢ Ensure shield continuity when extending shielded cables.

NOTE For detailed information, refer to the document System Wiring Guidelines, located in the Technical Library in the Unitronics’ website.
Wiring the Power Supply
The controller requires an external power supply.

• **** In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

Connect the +V and 0V  terminals as shown in theaccompanying figure. Connecting Ports

Note that below, the letters “xx” that is used in the model numbers means that the section refers both to B5/C5 and B10/C10 models.
I/O Connection Points
The IOs for these models are arranged in three groups of  fifteen points each, as shown in the figures to the right.
Top groups
Input connection points
Bottom group
Output connection points
The function of certain I/Os may be adapted via wiring and software settings. Wiring the Digital Inputs
The digital inputs are arranged in two isolated groups:

• I0-I9 share common CM0
• I10-I23 share common CM2
  Each group may be wired together as sink or source.
  Inputs I10-I17 can be configured as either normal digital inputs or as high speed inputs that can receive high speed pulse signals from sensors or shaft encoders.

High Speed Input Modes
Following are the different pin assignments for the high speed channels:

| Channel 1
---|---
I10| I11
Quadrature| Phase A| Phase B
Pulse+Direct ion| Pulse| Direction
Pulse| Pulse| Normal digital
Channel 2

I12| I13
Phase A| Phase B
Pulse| Direction
Pulse| Normal digital
| Channel 3
---|---
I14| I15
Quadrature| Phase A| Phase B
Pulse+Direct ion| Pulse| Direction
Pulse| Pulse| Normal digital
Channel 4

I16| I17
Phase A| Phase B
Pulse| Direction
Pulse| Normal digital

NOTE ▪ Input modes are set both by wiring and software.

NOTE
Use sink input wiring to connect a sourcing (pnp) device. Use source input wiring to connect a sinking (npn) device.
Wiring the Analog Inputs
Both inputs share the common point CM1.
NOTE ▪ The inputs are not isolated.

• Each input offers two modes: voltage or current. You can set each input independently.
• The mode is determined by the hardware configuration within the software application.
• Note that if, for example, you wire the input to current, you must also set it to current in the software application.

Voltage Current
Wiring the Relay Outputs (USC-xx-R38)

• **** To avoid risk of fire or property damage, always use a limited current source or connect a current limiting device in series with the relay contacts

The relay outputs are arranged in two isolated groups:
O0-O5 share the common return CM3.
O6-O11 share the common return CM4.
Increasing Contact Life Span
To increase the life span of the relay contacts and protect the controller from potential damage by reverse EMF, connect:

• a clamping diode in parallel with each inductive DC load,
• a RC snubber circuit in parallel with each inductive AC load

Wiring the Source Transistor Outputs (USC-xx-T42)
Output’s power supply
The use of any of the outputs requires an external 24VDC power supply as shown in the accompanying figure.
Outputs
Connect the +VO and 0VO terminals as shown in the accompanying figure.
O0-O15 share common return 0VO. Installing Uni-I/O™ & Uni-COM™ Modules
Refer to the Installation Guides provided with these modules.

• Turn off system power before connecting or disconnecting any modules or devices.
• Use proper precautions to prevent Electro-Static Discharge (ESD).

Uninstalling the Controller

Notes:

1. Eight of the digital inputs (I10-I17) may be configured to function either as normal, or as high speed digital inputs, that can receive high speed pulse signals from up to two sensors or shaft encoders.

2. The Local Expansion Kits comprise a Base unit, an End unit, and a connecting cable. You must plug the Base Unit into the last Uni-I/O™ module plugged into the controller. If no module is present, plug the Base unit into the I/O Bus connector.

3. Uni-COM™ CB modules plug directly into the Uni-COM Jack on the side of the controller. Uni-COM modules may be installed in the following configurations:
   – If a module comprising a serial port is plugged directly into the controller, it may be followed only by another serial module, for a total of

4. – If your configuration includes a CANbus module, it must be plugged directly into the controller. The CANbus module may be followed by up to two serial modules, for a total of 3. For more information, refer to the product’s installation guide.

5. When replacing the unit’s battery, make sure that the new one has environmental specifications that are similar or better than the one specified in this document.

6. The USB device port is used to connect the device to a PC.

7. The 4-20mA input option is implemented using 0-20mA input range.

8. The analog inputs measure values that are slightly higher than the nominal input range (Input Over-range).
   Note that when the input overflow occurs, it is indicated in the corresponding I/O Status tag as well as by the respective input LED (see LED Indications), while the input value is registered as the maximum permissible value. For example, if the specified input range is 0 ÷ 10V, the Over-range values can reach up to 10.15V, and any input voltage higher than that will still register as 10.15V while the Overflow system tag is turned on.

9. See LED Indications Table for description of the relevant indications. Note that the diagnostics results are also indicated in the system tags and can be observed through the UniApps™ or the online state of the UniLogic®.

10. Step response and update time are independent of the number of channels that are used.

11. Life expectancy of the relay contacts depends on the application that they are used in. The product’s installation guide provides procedures for using the contacts with long cables or with inductive loads.

12. Outputs O0 and O1 can be configured as either normal digital outputs or as PWM outputs. PWM outputs specifications apply only when outputs are configured as PWM outputs.

13. This refers to the CONFIRM button on the controller USB Actions; press it if the indication requires.
