easy // Programmable Relays are ideal where multiple push buttons, relays and timers are used–car washes, automatic doors, lighting, pump control. The easy and MFD-Titan device series stands out with its user-friendly operation and programming, with particular importance being placed on simple circuit. Eaton Moeller EASY Relay.

The 4 cursor buttons can be used as inputs. Figure 7 Now use the cursor disk to move to the left, to the 2nd position, right next to the I1 symbol.

Combined with the “Random On-Delay” and “Random Off-Delay” timers shown in the previous section, the lights will come on not at the exact same times each day but rather at somewhat variable times, thereby more closely simulating an occupied house.

Figure 3 Program Menu: Units that lack the buttons and LCD Screen will automatically load the program from the card to the unit each time the unit is powered up.

When the preset time is elapsed, then timer contact T1 will activate output relay Q1 The “X” in the upper-left corner easy12 the parameter display indicates the type of timer, in this case “on-delay”. A manhal memory “Card” is available which is used to store the program much in the way one would use a Floppy Disk.

Siemens Sirius and Klockner Moeller Eaton stocking distributor: Permissible displays include actual text as well as variables such as actual values and setpoints of timers, counters, and the time of day. The Loads may be relay coils, small motors, lights, etc. On models that have the clock, the “WE” on the right indicates “wednesday” and below that is the time of day in 24 hour format. A pulse will latch the relay in, then a later pulse will manuak it back out.

Figure 34 Manusl P-Buttons: The clocks are not aware of the year or date, but they do track the day of the week. Relay circuits often require “closed east512 and this is done with negation. Begin with the blank screen and your blinking cursor is in the upper left corner. If you see a “STOP” button, the unit is in run mode, and pressing it will stop processing. The OK button is used to select menu functions highlighted by the cursor.

This comparator is activated when the voltage on I8 is less than or equal to a setpoint value. The number at the top Simply move to any contact on your diagramm and press OK to select it.

If the password appears as “XXXX” then a previous password had been set and is stored in memory. This delay is ,anual 20 milliseconds.

Note the 2 numerical displays show the actual voltages present at the 2 inputs. This means that the parameter screen for this particular timer is available even when a password is active, and one may change the time values but not the function or type.

There are 6 specific analog comparators to ewsy512 with: Available Functions Figure 14 Negation: This screen begins as a blank, and you type in your desired program.

This comparator is activated when the voltage on I7 is less than or equal to a setpoint value. Then press ALT, and a small line will appear above the symbol.

A momentary pulse to the TT1 coil will cause the time to start running, and the contacts switch on immediately, then switch off after the time is elapsed. This can make a very handy alternator circuit. A text will be displayed whenever that Text Variable D1 thru D8 amnual activated.


If a password is set, you cannot view the program. Supply Voltage AC Units: Voltages from analog inputs I7 and I8 can be displayed as actual voltage or as a scaled number representing maanual function.

The unit must be powered up to use it’s functions. Figure 17 Marker Relays: If input 1 I1 is activated then output relay 1 Q1 is activated. If the requirements exceed the 12 inputs and 6 outputs of the series units, it is possible to select a Master and a Slave unit and connect them together, thereby making available 24 inputs and 12 outputs.

Below that the “S” indicates “seconds”.

The input I1 and the output relay Q1 are now “wired” together. The loads must all be 24 Volt DC operated, and you must observe polarity. Enter an incorrect password 3 times, and the program will be deleted and the password removed and you may then put in a new program.

Figure 35 Startup Mode: If the password appears as “” then no password is stored. In this circuit diagram Clock 1 contact ” 1″ controls output relay Q1 Note there are 2 parameter screens shown, exsy512 4 are possible. Figure 12 Parameter Display: Figure 27 Text-Display Variables: Now use the cursor to move to the 2nd row, all the way to the left.

Those 4 letters are mxnual as “channels”. A momentary activation of the reset coil RT1 will stop the timer. Use the Program menu selection from the Main Menu to enter your password. The password may be any number from thru See the section on “marker relays” for the correct method.
