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.

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.
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 is AC. 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 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. A power 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 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 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. - 4 -

1 DC power supply 2 Emergency stop 3 Circuit protection fuse 4 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. 5 Mutually exclusive output: For example, and Y4 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.

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. - 7 -
