WARNING
•This Instruction Sheet only provides descriptions for electrical specifications, general specifications,
installation & wiring, troubleshooting and peripherals. Other detail infromation about programming and
commands is compatible with ELC-PC/PA/PH series; please see ELC Application Manual. For more
information about the optional peripherals , please see individual product 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.
•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 . Do NOT touch terminals when power on.
•Battery replacement: use UL component type: TDRTL-2150/S lithium battery. Refer to following table for
battery life. (NOTE: RTC should be reset after changing battery).

•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.

1 INTRODUCTION
1.1 Model Name Explanation and Peripherals
Thank you for choosing Eaton Logic Controller (ELC) series products. The ELC-PA series is a 10-point (4DI+2DO+
2AI+2AO) controller unit. ELC-PA uses the same commands and functions as ELC-PA series, 2-CH 12-bit analog
voltage/current input and 2-CH 12-bit analog voltage/current output are all bipolar. There is also built-in, 2-digit
7-segment display corresponds to internal register directly to display ELC station or user-defined code.

6 INSTALLATION & WIRING
6.1 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.

6.2 Wiring
22-16AWG
<1.5mm
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.
3. DO NOT store the ELC in an atmosphere that is dusty, smoky, with
metallic debris or high temperature or high humidity.
4. DO NOT install the ELC on a shelf or on an unstable surface.
6.3 Power Input Wiring
1. When DC voltage is supplied to the ELC, make sure the power is at terminals 24VDC and 0V (power range
is 20.4VDC~28.8VDC). When voltage is lower than 20.4VDC, ELC will stop operating, all outputs will turn
OFF and the ERROR LED will flash continuously.
2. If the power-cut time is less than 10ms, the ELC still operates unaffectedly. If the power-cut time is too long
or the power voltage drops, the ELC will stop operating and all the outputs will be Off. Once the power is
restored, the ELC will return to operate automatically. (There are latched auxiliary relays and registers inside
of the ELC, please be aware when programming.)

■Preparation
1. Prior to applying power, please verify that the power lines and the input/output wiring are correct. And be
advised not to supply AC110V or AC220V into the I/O terminals, or it might short-circuit the wiring and
would cause direct damage to the ELC.
2. After using the peripheral devices to write the program into the ELC and that the ERROR LED of the ELC
is not on, it means that the program in use is legitimate, and it is now waiting for the user to give the RUN
command.
3. Use ELC-HHP to execute the forced On/Off test of the output contact.
■Operation & Test
If the “ERROR” LED of the ELC is not blinking, use RUN/STOP switch or the peripheral devices (ELC-HHP or
ELCSoft) to give the RUN command, and the RUN indicator will then be on. If the “RUN” LED is not on, it indicates
that there is no program inside the ELC.
ELC-HHP could be utilized to monitor the settings and the registered values of the timer (T), the counter (C) and the
data register (D) during operation, and moreover, to force the output contacts to conduct the On/Off action. If the
ERROR LED is on (but not blinking), it means that the setting of the user’s program has exceeded the preset
overtime limit, thus users have to double check the program and perform the On/Off function again. (The ELC is at
this moment back to STOP automatically)
■ELC Input/Output Reaction Time
The total reaction time from the input signal to the output operation is calculated as follows:
Reaction Time = input delay time + program scan time + output delay time
Input delay time 10ms (factory default), 0~20ms adjustable. Refer to the usage of special
registers D1020~1021.
Program scan time Please refer to the usage of special register D1010.
Output delay time Relay module: 10ms. Transistor module: 20~30us.
■Basic Commands and Application Commands of the ELC:
1. The basic commands and the application commands of the ELC of this series are totally applicable to the
ELC. Refer to the ELC Technique Application Manual for relevant basic commands and application
commands.
2. The ELC-HHP handheld programming panel and the ELCSoft (Windows version) editing program of the
ladder diagram are both good for use with the ELC. Also, the ELC could connect with the
ELC-PA10AADR/T through specific transmission wire to execute the program transmission, the ELC
control and the program monitoring.

9TROUBLESHOOTING
When the ERROR LED is on (not blinking), users should make a judgment from the special relay M1008 of the
ELC. If it is On, it indicates that the execution time of the program loop has exceeded the time-out setting (set by
D1000). Please turn the ELC RUN/STOP switch to STOP, and find out the address of the time-out program by
special data register D1008. ”WDT” command can be used to solve the problem.
Output LED indicates if the output signals are On or Off. Please check the following items when the LED On/Off
indication does not correspond to the commands: 1. Output contacts may be melted and stuck together due to a
short circuit or current overload. 2. Check wiring and verify that the screws are tight.
If incorrect programs are input to the ELC, or that the commands and the components exceed the allowable
range, the indicator will blink. At this moment, the user should check both the error codes saved in the ELC data
register D1004. The address that the error occurs will be stored in data register D1137 (the address saved in
D1137 is invalid in case of common loop error).
There is a “POWER” LED at the front of the ELC. When the ELC is powered On, the green LED light will be on.
If the indicator is not on when the ELC is powered up and with the input power being normal, it is an indication
that the ELC is out of order. Please have this machine replaced or have it repaired at a dealer near you.
The On/Off signals of the input point could be displayed through the “Input” LED, or the status of the input point
could be monitored through the device monitoring function of ELC-HHP.
Identify the status of the ELC. When the ELC is in operation, this light will be on, and users could thus use
ELC-HHP or the editing program of the ladder diagram to give commands to make the ELC “RUN” or “STOP”.
When the battery voltage is low, the “BAT.LOW” LED will be on, and the battery should be replaced as soon as
possible; otherwise the user program and the data in latched area will be lost. (On the unplugged ELC, please
change the battery within 3 minutes to retain the ELC’s internal user programs and data).
“RS-232” LED will light when RS-232 is receiving data, “RS-485” LED will light when RS-485 is transferring
data.
Judge the errors by the indicators on the front panel. When errors occurred on ELC, please check:
“ALARM” LED will blink if AD/DA conversion data exceeds usage range when PA MPU is RUN.
A D LED indicator. A D LED will blink if PA MPU is RUN.
