Thank you for choosing this Eaton Logic Controller (ELC) series has

controllers with 10 to 40 embedded I/O points. To ensure proper installation,

operation and maintenance, please read this instruction sheet carefully

before installing ELCB-PB.

This instruction sheet provides only information on the electrical

specification, general functions, installation and wiring. It should be read

and understood before attempting to install or use the unit.

Further information can be found in the ELC series Programming

Manual.

These are OPEN TYPE controllers and therefore should be installed in

an enclosure free of airborne dust, humidity, electric shock and vibration.

Your application may require that the enclosure be locked to prevent

non-maintenance staff from operating the controller (e.g. key or specific

tools that are required for opening the enclosure) in cases where danger

and damage to equipment or personnel may occur.

DO NOT connect AC power to any of the DC I/O terminals; serious

damage may occur. Check all wiring before switching on power.

Ensure that the ground terminal is correctly grounded in order to

prevent electromagnetic interference.

This manual is subject to change without notice.

Installation

Please install your controller in an enclosure with sufficient space around it

to allow proper ventilation, as shown in the figure.

DIN Rail Mounting: When mounting the

ELCB to 35mm DIN rail, be sure to use the

retaining clip to stop any side-to-side

movement of the ELCB and reduce the

chance of wires becoming loose. The

retaining clip is at the bottom of the ELCB.

- 4 -

To secure your controller to the DIN rail, pull the clip down, place it onto

the rail and gently push the clip up. To remove the ELCB, pull the

retaining clip down with a flat screwdriver and gently remove the ELCB

from DIN rail.

Wiring

1. Use 12-24 AWG single-core bare wire or multi-core (stranded) wire for

the I/O wiring. The ELCB terminal screws should be tightened to 3.80

kg-cm (3.30 in-lbs) using 60/75°C copper conductor only.

2. DO NOT wire empty terminals. DO NOT place input signal wires and

power wires in the same wiring circuit.

3. DO NOT drop tiny metallic conductors into the ELCB while installing the

controller or other equipment.

Power Supply

The input power supply for the ELCB-PB controller isAC. When operating

ELCB-PB, please note the following points:

1. The range of the input voltage should be 100 ~ 240VAC. The power

supply should be connected to L and N terminals. Please note: wiring

110VAC or 220VAC to a +24V output terminal or to digital inputs will

result in serious damage to the ELCB.

2. Use 1.6mm wire (or larger) for the grounding ELCB.

3. Apower loss for less than 10ms will not affect the operation of the ELCB.

However, longer power loss or a sustained drop of power supply voltage

will stop the running of the ELCB, and all outputs will turn “OFF”. When

proper power is restored, the ELCB will resume operation. (Please keep

this in mind when you use latched auxiliary relays and registers in your

ELCB program.)

4. Please refer to the electrical specification table for the maximum output

of the +24V power supply output terminal for each controller. DO NOT

connect other external power supplies to this terminal. Every input point

requires 5 to 7mA to drive when powered by rated voltage 24V to 30V

(i.e. 16 input points will require 80 to 112mA to drive). The +24V input on

ELCB-PB is only for digital input points; other external loads are not

supported.

Safety Wiring

In an ELCB control system, many devices are controlled at the same time,

and actions of any device could influence another device, i.e. breakdown of

any device may cause the breakdown of the entire control system.

Therefore, we suggest you wire a protection circuit at the power supply

input terminal. See the figure below.

Mutually exclusive output: For example, Y4 and Y5 control the forward running and

reverse running of the motor, forming an interlock for the external circuit, together

with the ELCB internal program, to ensure safe operation in case of any unexpected

errors.

The output of the transistor module is “open collector”. If Y0/Y1 is set to pulse

output, the output current has to be 0.05 ~ 0.5A to ensure normal operation of the

output.

1. Diode suppression: Used with smaller loads.

2. Diode + Zener suppression: Used with larger loads, and for rapidly switching

applications.

Note: 1. Terminal resistors are suggested to be connected to the master, and the last

slave, with resistor value of 120.

2. To ensure communication quality, please wire using double shielded twisted

pair cable (20AWG).

3. When voltage drop occurs between the internal ground references of two

systems, connect the systems with Signal Ground point (SG) for achieving

equal potential between systems so that a stable communication can be

obtained.
