Panel Mounting

Before you begin, note that the mounting panel cannot be more than 5 mm thick.

UL Listed Models: To meet the UL508 standard, panel-mount the device on the flat surface of a Type 1 enclosure.

1. Make a panel cut-out of the appropriate size:
   • V130/V350/V130J/V350J: 92x92 mm (3.622"x3.622").
   • V430J: 122.5x91.5 mm (4.82"x3.6").
2. Slide the controller into the cut-out, ensuring that the rubber seal is in place.
3. Push the mounting brackets into their slots on the sides of the panel.
4. Tighten the bracket's screws against the panel. Hold the bracket securely against the unit while tightening the screw.
5. When properly mounted, the controller is squarely situated in the panel cut-out.

Wiring

• ❗ Do not touch live wires.
• Install an external circuit breaker. Guard against short-circuiting in external wiring.
• Use appropriate circuit protection devices.
• Unused pins should not be connected. 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 0.5 N·m (5 kgf·cm).
• 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 3.31 mm² –0.13 mm² wire (12-16 AWG):

1. Strip the wire to a length of 7±0.5mm (0.270–0.300“).
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.

Additional wiring notes:

• Input or output cables should not be run through the same multi-core cable or share the same wire.
• Allow for voltage drop and noise interference with I/O lines used over an extended distance. Use wire that is properly sized for the load.
• The controller and I/O signals must be connected to the same 0V signal.

Power Supply

The picture is for illustration only.

The controller requires an external 12VDC or 24VDC power supply.

Requirements: The power supply must include double insulation. Outputs must be rated as SELV/PELV/Class2/Limited Power.

• ❗ Use separate wires to connect the functional earth line (pin 3) and the 0V line (pin 2) to the system earth ground.
• Install an external circuit breaker. Guard against short-circuiting in external wiring.
• Double-check all wiring before turning on the power supply.
• Do not connect either the 'Neutral' or 'Line' signal of the 110/220VAC to the device's 0V pin.
• In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

Diagram Description: Shows two connection diagrams for power supply: one for 24VDC with circuit protection, and one for V130/V350 with circuit protection.

Earthing the PLC+HMI

To maximize system performance, avoid electromagnetic interference by:

• Mounting the controller on a metal panel.
• Connect each common and ground connection directly to the earth ground of your system.
• For ground wiring, use the shortest and thickest possible wire.

Communication

V130/V130J: These models comprise a built-in RS232/RS485 serial port (Port 1).

V430J/V350/V350J: These models comprise built-in ports: 1 USB and 1 RS232/RS485 (Port 1).

Note that physically connecting a PC to the controller via USB suspends RS232/RS485 communications via Port 1. When the PC is disconnected, RS232/RS485 resumes.

RS232/RS485 Port

• ❗ Turn off power before making communications connections.
• ? Caution: Always use the appropriate port adapters.
• ? Caution: Signals are related to the controller's 0V; the same 0V is used by the power supply. The serial port is not isolated. If the controller is used with a non-isolated external device, avoid potential voltage that exceeds ± 10V.

Usage:

• Use RS232 to download programs from a PC, and to communicate with serial devices and applications, such as SCADA.
• Use RS485 to create a multi-drop network containing up to 32 devices.

Pinouts

The pinouts below show the PLC port signals.

* Standard programming cables do not provide connection points for pins 1 and 6.

** When a port is adapted to RS485, Pin 1 (DTR) is used for signal A, and Pin 6 (DSR) signal is used for signal B.

It is possible to establish a PC to PLC connection using RS232 even when the PLC is set to RS485 (this eliminates the need to open the controller to set jumpers). To do so, remove the RS485 connector (pins 1 & 6) from the PLC and connect a standard RS232 programming cable. This is possible only if DTR and DSR signals of RS232 are not used.

Setting RS232/RS485 Communication Parameters, V130/V350/V130J/V350J

This port may be set to either RS232 or RS485 via jumper. The accompanying figure shows the jumper factory default settings.

Jumpers:

• Set communications to RS485, by setting both COMM jumpers to '485’.
• Set RS485 termination, by setting both TERM jumpers to 'OFF'.

To access the jumpers, you must open the controller according to the instructions on page 8.

Diagram Description: Shows jumper configuration for RS232/RS485 Select (COMM jumpers) and RS485 Termination (TERM jumpers).

Setting RS232/RS485 Communication Parameters, V430J

This port may be set to either RS232 or RS485 via DIP switches. The table shows the DIP switches factory default settings. Use the table to adapt the settings.

* Default factory setting.

** Causes the unit to function as an end unit in an RS485 network.

USB Port

? Caution: The USB port is not isolated. Make sure that the PC and the controller are grounded to the same potential.

The USB port may be used for programming, OS download, and PC access.

Opening the Controller (V130/V350/V130J/V350J Only)

Before performing these actions, touch a grounded object to discharge any electrostatic charge. Avoid touching the PCB board directly. Hold the PCB board by its connectors.

1. Turn off the power supply, disconnect, and dismount the controller.
2. The back cover of the controller comprises 4 screws, located in the corners. Remove the screws, and pull off the back cover.

Changing Communication Settings (V130/V350/V130J/V350J Only)

1. To access the communication jumpers, hold the Power supply PCB board by its edges and steadily pull the board off.
2. Locate the jumpers, and then change the settings as required, according to the jumpers' settings shown on page 7.

Closing the Controller (V130/V350/V130J/V350J Only)

1. Gently replace the board. Make certain that the pins fit correctly into their matching receptacle. Do not force the board into place; doing so may damage the controller.
2. Replace the back cover of the controller and fasten the corner screws.

Note that you must replace the back cover securely before powering up the controller.
