1 INTRODUCTION

1.1 Model Explanation and Peripherals

Thank you for choosing Eaton Logic Controller (ELC) series products. The analog output module

ELC-AN02NANN can read and write analog output data by using the FROM / TO commands via ELC controllers. The analog output module receives 12-bit digital data of 2 groups from ELC and transforms it into 2 points of an analog output signal (voltage or current). There are 49 CR (Control

Register) in each module and each register is 16 bits in length.

1. The content of CR#0 is model type; user can read the data from the module to know the type of extension module.

2. CR#1 is used to set two inner channels working mode of analog output module. Every channel has four modes to set and can be set individually. For example: setting CH1 to mode 2

(b2~b0=010), CH2 to mode 1(b5~b3=001). It needs to set CR#1 to H000A. The factory setting of

CR#1 is H0000.

5 INSTALLATION & WIRING

1. Installation of the DIN rail

The ELC can be secured to a cabinet by using the DIN rail that is 35mm high with a depth of 7.5mm.

When mounting the ELC on the DIN rail, be sure to use the end bracket to stop any side-to-side motion of the ELC, thus to reduce the chance of the wires being pulled loose. At the bottom of the

ELC is a small retaining clip. To secure the ELC to the DIN rail, place it onto the rail and gently push up the clip.

To remove it, pull down the retaining clip and gently pull the

ELC away from the DIN rail. As shown on the right:

When installing the ELC, make sure that it is installed in an enclosure with sufficient space (as shown on the right) to its surroundings so as to allow heat dissipation.

Notes:

1. Please use 22-16AWG (1.5mm) wiring (either single or multiple core) for I/O wiring terminals. The specification for the terminals is as shown on the left. ELC terminal screws should be tightened to

1.95 kg-cm (1.7 lb-in). Use Copper Conductor Only, 60/75 °C.

2. I/O signal wires or power supply should not run through the same multi-wire cable or conduit.

6 INITIAL ELC START-UP

Lamp display:

1. When power is on, POWER LED will be lit and ERROR LED will be lit for 0.5 second.

2. It is normal that POWER LED should be lit and ERROR LED should turn off. When power supply is lower than 19.5V, ERROR LED will blink continuously till the power supply is higher than

19.5V.

3. When connected to ELC in series, RUN LED on MPU will be lit and A/D LED or D/A LED should blink.

4. After receiving the first RS-485 command during controlling by RS-485, A/D LED or D/A LED should blink.

5. After converting, ERROR LED should blink if input or output exceeds upper bound or lower than lower bound.
