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 circuit diagram in Figure 21 shows comparator A1 will “set” output relay Q1, and comparator A2 will “reset” Q1.

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, press the OK button, and I1 appears. Now use the cursor disk to move to the left, to the 2nd position, right next to the I1 symbol.

There are 6 specific analog comparators to work with: The series units have the ability to “jump” to another section of the program, thereby skipping certain portions. This way the programmer need not travel to the job-site to make program changes. In cases where severe interference is present, a shielded 2-wire cable should be used. Certain “inexpensive” proximity switches need to be connected to a load at all times for them to function properly.

In this circuit diagram Clock 1 contact ” 1″ controls output relay Q1 Note there are 2 parameter screens shown, though 4 are possible.

Another application might be to control lights in a home while the owner is away on vacation. See the section on System Menu, below. Figure 39 Figure This screen is not ,anual if a password is set and “active”, you must enter the password first and deactivate it. The contacts can be used like any other contact, however if the input voltage fluctuates slightly, it may be good to use latch relays so as to prevent chattering.


Changing or viewing the program.

Enter the symbols shown at left. Use the up and down cursors to change individual values.

This caution applies to all types of relays, counters, timers, etc. Below that the “S” indicates “seconds”. Use the Program menu selection from the Main Menu to enter your password. Shown here in the circuit diagram, I1 pulses the CC1 counter eqsy512 and the count is incremented by 1 for each pulse. If the password appears as “XXXX” easy52 a previous password had been set and is stored in memory.

More specific information appears in the next section below. Power the unit up, then press the OK button 3 times and you will arrive at the blank screen where you will enter your program. This can make a very handy alternator circuit. An aesy512 password prevents: 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.

The text display in Fig. Figure 11 Programming Parameters: This comparator is activated when the voltage on I7 is less than or equal to a setpoint value.

These are handy manuaal relays which can be used as memory or to extend a row if more than 3 contacts are needed such as in the ILLEGAL example shown at the left. If the password appears as “” then no password is stored. 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.


Also note that the Series units with 12 inputs also use I7 and I8 as their analog inputs. The input I1 and the output relay Q1 are now “wired” together.

Wiring for Series DC units is identical. Relay circuits often require “closed contacts” and this is done with negation. The various menus can be displayed in any of these languages: AC units do not offer analog inputs. These are used to count pulses, usually from inputs. The DC models are able to accept 2 analog volt sensors.

Figure 6 Begin with the blank screen and your blinking cursor is in the upper left corner.

Mamual our main page for Klockner Moeller and Siemens parts. Input I2 activates the “reset” timer coil which will rest the time count back down to zero, if desired. Here are the various types of timers with their parameter symbols: When the TT1 “trigger” coil is activated, the time count begins and the timer’s contacts close when the preset time is reached and then remain closed until power is removed from the trigger coil TT1.
