: A shorter reference for quick installation and electrical specifications. Core Programming Guide The EASY512 uses a simplified Ladder Diagram (LD)
language. You can program it directly on the unit using the LCD and pushbuttons or via a PC. 1. On-Device Navigation The unit has 4 main buttons ( DEL, ALT, ESC, OK ) and a cursor disk: 3 times from the power-up screen to enter the program area. Control Parts Adding Elements : Use the cursor to move to a blank spot. Press to add an input (e.g., ) and move to the far right to add an output coil (e.g., Control Parts
to toggle the line-drawing tool, then use the cursor arrows to "wire" inputs to coils. Control Parts button to remove specific elements or entire circuit rungs. 2. Available Functions Inputs/Outputs : 8 digital inputs (I1–I8) and 4 relay outputs (Q1–Q4). Internal Relays (Markers) : 16 internal "M" relays for complex logic. Timers and Counters
: 8 timers (T) and 8 counters (C). Parameters like delay time or preset values are set in the Real-Time Clock : Set the system time and day under to use time-based triggers. Control Parts Wiring and Electrical Setup Power Supply : L and N terminals require Acotron Electrónica Industrial : Inputs I1–I8 respond to 230V AC signals. Proximity Switch Tip Wire the Timer:
: For AC inductive proximity switches, use inputs 7 or 8 as they draw higher current, or use a 2k ohm "pulldown" resistor. Control Parts
: Relay contacts are volt-free switches that can handle up to 8A. Acotron Electrónica Industrial Software Option Klockner Moeller EASY 512 Programming Instructions
The Moeller (Eaton) EASY512-AC-RC is a DIN-rail mounted intelligent control relay featuring 8 digital inputs and 4 relay outputs (8A), with programming capabilities via on-device keypad or easySoft software. The device supports 128 lines of logic, including a real-time clock and 100-240V AC power supply, with detailed operational procedures outlined in the official documentation. For comprehensive programming instructions, refer to the official Eaton manual at Moeller's EASY-512-AC-RC Programmable controller with real
This is a practical, need-to-know guide for programming the Moeller (now Eaton) easy512-AC-RC, focusing on real-world usage since the original manual is over 400 pages.
You want Q2 to turn on 5 seconds after I2 is pressed.
| Symptom | Probable cause | Fix |
|---------|----------------|-----|
| Outputs stay on after power loss | No retentive settings | Use M marker or set block as retentive in PARAM |
| Counter resets unexpectedly | Power cycle clears it | Set counter retentive: C01 → Edit → Retain=Yes |
| RTC schedule not working | Battery dead or not set | MENU → Clock → Set date/time, replace CR2032 if old |
| Program won't transfer | Wrong cable or baud rate | Use 9600 baud, 8N1, easySoft cable (not standard USB-RS232) |
| Input reads ON when nothing connected | Sinking/sourcing mismatch | Check common (C0) connection: Connect C0 to N (AC) or 0V (DC) |
The easy500 uses circuit diagram programming – similar to relay ladder logic but displayed as connections between contacts and coils. 4 relay outputs
| Problem | Likely cause | Solution |
|---------|--------------|----------|
| No outputs | STOP mode | Press RUN button |
| Input LED off but voltage present | Wrong input type (DC vs AC) | Check model: AC only |
| Program lost after power cycle | Not saved | Save before exiting PROG |
| "Overflow" error | Too many connections per rung | Break into multiple rungs |
| "No end coil" | Missing END coil | Add END coil at last page |
