Inserting the Battery

In order to preserve data in case of power-off, you must insert the battery.

The battery is supplied taped to the battery cover on the rear of the controller.

1. Remove the battery cover shown on page 4. The polarity (+) is marked on the battery holder and

on the battery.

2. Insert the battery, ensuring that the polarity symbol on the battery is:

- facing up

- aligned with the symbol on the holder

3. Replace the battery cover.

Mounting

Dimensions

Note that the LCD screen may have a single pixel that is permanently either black or white.

Panel Mounting

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

1. Make a panel cut-out according

to the dimensions in the figure

to the right.

V570-57-T34 Installation Guide

Unitronics

2. Slide the controller into the cut-

out, ensuring that the rubber

seal is in place.

3. Push the 4 mounting brackets

into their slots on the sides of

the controller as shown in the

figure to the right.

4. Tighten the bracket 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 as shown

below.

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.

Vision™ OPLC™

Unitronics

Wiring Procedure

Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm 2–3.31 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.

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 input lines used over an extended distance. Use

wire that is properly sized for the load.

I/Os

This model comprises a total of 16 digital inputs, 2 analog inputs and 16 outputs.

1. Input functionality can be adapted as follows:

All 16 inputs may be used as digital inputs. All 16 may be wired in a group, via a pin on the

connector, as either npn or pnp. In addition, according to jumper settings and appropriate wiring:

- Inputs 160& 162 can function as either a high-speed counter, as part of a shaft-encoder, or as

a normal digital input

- Inputs 161 & 163 can function as either a counter reset, as part of a shaft-encoder, or as a

normal digital input

- If inputs 160& 162 is set as a high-speed counter (without reset), inputs 161 & 163 can function

as normal digital inputs

2. Output functionality is as follows:

- All 15 (161-175) outputs are pnp outputs

- Output 160 is an npn - High Speed Output

Power Supply

The controller and the digital IO require an external 24VDC power supply.

A non-isolated power supply can be used if a 0V signal is connected to the chassis.

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 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.

Earthing the Power Supply

To maximize system performance, avoid electromagnetic interference by:

Mounting the controller on a metal panel.

Earthing the controller’s power supply: connect one end of a 14 AWG wire to the chassis

signal; connect the other end to the panel.

Note: If possible, the wire used to earth the power supply should not exceed 10 cm in length.

However, it is recommended to earth the controller in all cases.

Communication Port

This series comprises 2 RS232/RS485 serial ports and a CANbus port.

Turn off power before making communications connections.

Caution

Always use the appropriate port adapters.

The serial ports are type RJ-11 and may be set to either RS232 or RS485 via DIP switches, in

accordance with the table shown below.

By factory default, the port is set to RS232, termination ON.

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.

To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC to

the PLC via the programming cable. Note that this is possible only if flow control signals are not used

(which is the standard case).
