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.

If a password is set, you cannot view the program. Line Fuse should be minimum 1 Amp slow-blow.

Mxnual Q1 is energized when I1 is activated, and drops out if I1 is deactivated. When the preset time is elapsed, then timer contact T1 will activate output relay Q1 The “X” in the upper-left corner of the parameter display indicates the type of timer, in this case “on-delay”. Up to 8 Text Variables D1 thru D8 can be defined, each of up to 12 characters. Wiring for Series DC units is identical.

You can move around the parameter display using only the right and left cursor.

The maximum preset isand maximum count is Certain “inexpensive” proximity switches need ezsy512 be connected to a load at all times for them to function properly. Depending on the proximity switch, there are 3 possible solutions: In cases where severe interference is present, a majual 2-wire cable should be used. Basic Programming Figure 5 Circuit Diagram: If the password appears as “XXXX” then a previous password mqnual been set and is stored in memory.

The text display in Fig. Figure 11 Programming Parameters: Input I1 activates the TT1 timer “trigger” coil, and the time count begins. An obvious application for this would be a “minimum-run” function perhaps for a pumping system, or perhaps to have a cooling fan continue running after a motor has stopped. Here use the up cursor to change the “1” to a “2” and you will have “I2”.

This comparator is activated when the voltage on I8 is greater than or equal to a setpoint value. Figure 42 Connecting AC Inputs: This comparator is activated when the voltage on I7 is greater than or equal to a setpoint value.

If the requirements exceed the 12 inputs and 6 outputs of the series units, it is possible to select a Master and a Slave amnual and connect them together, thereby making available nanual inputs and 12 outputs. The loads must all be 24 Volt DC operated, and you must observe polarity. Figure 39 Figure Figure 10 Fill in any missing “wires” and you’re done!

Figure 20 Clock Controllers ” “: Then press ALT, and a small line will appear above the symbol. Also note that the Series units with 12 inputs also use I7 and I8 as their analog inputs.

Note the 2 numerical displays show the actual voltages present at the 2 inputs. This can make a very handy alternator circuit. 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. More specific information appears in the next section below.

As the preset amount is reached, contact C1 activates output relay Q1 On the parameter display, the left number is the preset amount, and the right number is the running total. Setting a password of will easu512 delete a previous password. A pulse will latch the relay in, then a later pulse will reset it back out.

These are always connected to inputs I7 and I8.

If I2 activates the direction coil DC1, then pulses from I1 will count down I3 can easj512 used to reset the counter back to zero. 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.


The DC models are able to accept 2 analog volt sensors.

Changing unprotected relay function parameters. The various menus can be displayed in any of these languages: Press “P ON” to activate.

Fill in any missing “wires” and you’re done! Output Relay Q Eaxy512 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. Simply move to any contact on your diagramm and press OK to select it. If you see a “STOP” button, the unit is in run mode, and pressing it will stop processing. The Card Menu shown in Figure 41 has 3 options: Figure 27 Text-Display Variables: A momentary activation of the reset coil RT1 will stop the timer dead and the elapsed time will remain at zero.

The password may be any number from thru You may not use the latching coil AND the normal coil of the same relay in the same circuit diagram. The lower picture shows the correct method, using marker relay M1. This is shown as Q3. Another pulse to the TT1 coil while the time is already running will restart the time count and continue running. The time count begins the moment the coil is activated, even if manul coil remains activated.
