WARNING
•
This Instruction Sheet only provides descriptions for electrical specifications, general
specifications, installation & wiring, troubleshooting and peripherals. For more information about
the optional peripherals, please see ELC Application Manual.
•
This is an OPEN TYPE Controller. The ELC should be kept in an enclosure away from airborne
dust, humidity, electric shock risk and vibration. Also, it is equipped with protective methods
such as some special tools or keys to open the enclosure, so as to avoid the hazard to users
and the damage to the ELC. Do NOT touch terminals when power on.
•
Never connect the AC main circuit power supply to any of the input/output terminals, as it will
damage the ELC. Check all the wiring prior to power up. To avoid any electromagnetic noise,
make sure the ELC is properly grounded .
•
Warning – Do not disconnect while circuit is live unless area is known to be non-hazardous.
•
Power, input and output (I/O) wiring must be in accordance with Class 1, Div. 2 wiring methods -
Article 501-10(B)(1) of the National Electrical Code.
•
Suitable for use in Class 1, Division 2, Groups A, B, C, D or Non-Hazardous locations only.
•
Warning – Explosion hazard - Substitution of components may impair suitability for Class 1,
Division 2.
•
Warning – Explosion Hazard - Do not disconnect equipment unless power has been switched
off or the area is known to be Non-Hazardous.
1 INTRODUCTION
1.1 Model Explanation and Peripherals
Thank you for choosing Eaton Logic Controller (ELC) series products. The analog input module
receives external 4-point analog signal input (voltage or current) and transforms it into 14 bits digital
signal. The analog input module of ELC-AN04ANNN can read/write the data of analog input module
by using commands FROM / TO via ELC program. There are 49 CR (Control Register) in each
module and there are 16 bits in each register.

Give CH1 setting for example:
Reset to factory setting and set 1. When b0=0, user can set OFFSET and GAIN value of CH1 (CR#18,
#33 H 4021 O R/W characteristics adjustable
CR#24). When b0=1, inhibit user to adjust OFFSET and GAIN value of
priority
CH1 (CR#18, CR#24).
2. b1 means if characteristic register is latched. b1=0 (factory setting,
latched), b1=1 (not latched).
3. When b2 is set to 1, all settings will reset to factory setting.
