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.

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.

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.

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.

Power Supply

V570-57-T20B, & V570-57-T20B-J requires either an external 12 or 24VDC power supply.

Permissible input voltage range: 10.2-28.8VDC, with less than 10% ripple.

V570-57-T40B, require an external 24VDC power supply.

Permissible input voltage range: 20.4-28.8VDC, with less than 10% ripple.

Anon-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 Ports

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.

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 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).

*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.

RS232 to RS485: Changing DIP Switch Settings

The ports are set to RS232 by factory default.

To change the settings, first remove the Snap-in I/O Module, if one is installed, and then set the

switches according to the following table.

Removing a Snap-in I/O Module

1. Locate the four buttons on the sides of the controller, two on either side.

2. Press the buttons and hold them down to open the locking mechanism.

3. Gently rock the module from side to side, easing the module from the controller.

Re-installing a Snap-in I/O Module

1. Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O Module as

shown below.

2Apply even pressure on all 4 corners until you hear a distinct ‘click’. The module is now installed.

Check that all sides and corners are correctly aligned.

CANbus

These controllers comprise a CANbus port. Use

this to create a decentralized control network using

one of the following CAN protocols:

CANopen: 127 controllers or external

devices

CANLayer 2

Unitronics’ proprietary UniCAN: 60

controllers, (512 data bytes per scan)

The CANbus port is galvanically isolated.

CANbus Wiring

Use twisted-pair cable. DeviceNet® thick shielded

twisted pair cable is recommended.

Network terminators: These are supplied with the

controller. Place terminators at each end of the

CANbus network.

Resistance must be set to 1%, 121R,1/4W.

Connect ground signal to the earth at only one

point, near the power supply.

The network power supply need not be at the end

of the network
