From 12th April UPS will be implementing a temporary surcharge on all international shipments. See the section on System Menu, below.

Here in Fig. But, if I1 were activated, then Jump relay 1 :1 would activate and the entire second line containing I2 would be skipped and the program would continue at the :1 "contact" marker.

In all cases, I3 would still control output Q3. Up to 8 Text Variables D1 thru D8 can be defined, each of up to 12 characters. The text display in Fig. Permissible displays include actual text as well as variables such as actual values and setpoints of timers, counters, and the time of day. Voltages from analog inputs I7 and I8 can be displayed as actual voltage or as a scaled number representing their function. A text will be displayed whenever that Text Variable D1 thru D8 is activated.

The password may be any number from thru Setting a password of will completely delete a previous password. If a password is set, you cannot view the program. Use the Program menu selection from the Main Menu to enter your password.

An active password prevents: Changing or viewing the program. Copying the program. Changing System paramters. Changing unprotected relay function parameters. Figure 31 shows a typical parameter screen, in this case a timer.

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. If you forget your password, there is no "back door" into the unit: 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.

Press "P ON" to activate. The default is "RUN" and the programmer will likely want to connect a start button to an input to start the machine actually running.

This feature is useful where a machine must remember it's exact place in a continuing process. The Card may be plugged in when the unit is powered up. The unit must be powered up to use it's functions. This is shown in Figure 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.

The Memory Card provides a convenient way to update a program and send the Card to an untrained person in the field for installation.

This way the programmer need not travel to the job-site to make program changes. The Memory Card is also a convenient way to archive a copy of the program in case of damage to the unit.

Side-By-Side Connection: Figure 39 shows a Master unit and a Slave unit mounted side by side, connected by a small plug-connector that is included with the Slave unit. The Remote Connection Unit has terminals to connect wires to the remotely located Slave unit. The connection is made with 2 wires or a single twisted-pair and may have a maximum length of 30 meters, approximately feet. In cases where severe interference is present, a shielded 2-wire cable should be used.

Note: Only models specifically designated as Master or Slave can be used for expansion. Also note that the Series units with 12 inputs also use I7 and I8 as their analog inputs. The Loads may be relay coils, small motors, lights, etc. Wiring for Series units with transistor outputs are identical. Certain "inexpensive" proximity switches need to be connected to a load at all times for them to function properly.

This load serves to drain the charge from the sensor when it wants to indicate the "low" state. Cart 0. See our PLCs catalog. Click here for our related downloads. Press the OK button, for the Main Menu. Figure 2 Main Menu: You may move up and down using the cursor arrows on the large disk, your present selection is blinking. Figure 4 Circuit Diagram: This screen begins as a blank, and you type in your desired program.

This simple program has only one function: If input 1 I1 is activated then output relay 1 Q1 is activated. Basic Programming Figure 5 Circuit Diagram: 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.

Figure 6 Begin with the blank screen and your blinking cursor is in the upper left corner. Note that the screen is 4 columns wide, which allows for 3 contacts plus one coil on the right.

Press OK, and I1 will appear, indicating Input 1. Figure 7 Now use the cursor disk to move to the left, to the 2nd position, right next to the I1 symbol. Figure 8 Now use the cursor to move to the 2nd row, all the way to the left. Here, press the OK button, and I1 appears. Figure 9 Now move down to the 3rd line, and press OK twice to enter I1. Note you may use the same input symbol repeatedly.

Figure 10 Fill in any missing "wires" and you're done! Figure 11 Programming Parameters: Here is a program using a timer. Timers need parameters set for on-delay or off-delay, time, etc. Figure 12 Parameter Display: Shown here is a typical parameter display.

In the case of a timer, the top left symbol indicates type on-delay, off-delay, etc , in this case the X means "on-delay". Below that the "S" indicates "seconds". Available Functions Figure 14 Negation: Relay circuits often require "closed contacts" and this is done with negation. Simply move to any contact on your diagramm and press OK to select it. Then press ALT, and a small line will appear above the symbol. This is now a "normally closed" contact.

This works for any type of contact, timers, counters, clocks, etc. Output Q1 is energized when I1 is activated, and drops out if I1 is deactivated. Figure 17 Marker Relays: These are handy internal 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.

The lower picture shows the correct method, using marker relay M1. Figure 18 Counter Relays: These are used to count pulses, usually from inputs. A total is kept, visible on the parameter screen, and when a preset total is reached, the counter's contacts will switch over. Counters can count in either direction, plus or minus. If I2 activates the direction coil DC1, then pulses from I1 will count down I3 can be used to reset the counter back to zero. 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.

Figure 19 Timers: Shown here is a simple on-delay timer circuit and parameter display. Input I1 activates the TT1 timer "trigger" coil, and the time count begins. 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".

Here are the various types of timers with their parameter symbols: On-Delay, " X, " : 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. Figure 20 Clock Controllers " " : Models equipped with a clock can be used to control lighting and other functions on a regular time-of-day and day-of-the-week schedule. The clocks are not aware of the year or date, but they do track the day of the week.

As the clocks run continually, there is no "activation coil", one merely inserts the clock contact " " in the diagram as needed. In this circuit diagram Clock 1 contact " 1" controls output relay Q1 Note there are 2 parameter screens shown, though 4 are possible. These are always connected to inputs I7 and I8.

Analog Comparator Relays are available to process the information. Figure 24 Figure 25 P-Buttons: The 4 cursor buttons can be used as inputs. Figure 26 "if" Jumps: The series units have the ability to "jump" to another section of the program, thereby skipping certain portions. Note: This screen is not available if a password is set and "active", you must enter the password first and deactivate it. See below Figure 29 Figure 30 Figure 31 Password Protection: Setting a system password will prevent tampering with the program in the field and will prevent viewing of the program by unauthorized persons.

If the password appears as "" then no password is stored. If the password appears as "XXXX" then a previous password had been set and is stored in memory. If a password is set but not activated, then the password is stored in memory but is not used. The series units also have these additional languages: Portuguese, Dutch, Swedish, Polish and Turkish.

Setting the Debounce will cause an input to delay activation until a "steady" signal is received. This delay is approximately 20 milliseconds. Figure 34 Activating P-Buttons: The cursor arrow buttons on the unit can be programmed into the circuit for use as inputs, but they must be activated before their function will be available. Figure 35 Startup Mode: The unit can be set to begin running immediately upon power-up, or alternatively to power-up in the "stop" mode, requiring a manual start from the Main Menu.

Figure 36 Retention: The units can be set to "retain" or "remember" the value of various functions thru a power-down and resume running exactly where they left off when powered-up again. This card is a small memory chip that plugs into a little door on the lower right face of the unit, just above the output relay terminals. Expansion Units Figure 39 Figure 40 Expansion Units: 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.

The Master and Slave units can be located side-by-side or remote from each other: Side-By-Side Connection: Figure 39 shows a Master unit and a Slave unit mounted side by side, connected by a small plug-connector that is included with the Slave unit. Shown is a pushbutton on Input I2 and a limit switch on Input I4.

Wiring for Series DC units is identical. AC units do not offer analog inputs. The loads must all be 24 Volt DC operated, and you must observe polarity. A note on AC Inductive Proximity Switches: Certain "inexpensive" proximity switches need to be connected to a load at all times for them to function properly.

Depending on the proximity switch, there are 3 possible solutions: 1 Use input 7 or 8, they draw a greater current and this may suffice. Line Fuse should be minimum 1 Amp slow-blow. Figure 1. Status Screen: this shows the condition of the inputs I and the outputs Q.

Figure 2. Main Menu: You may move up and down using the cursor arrows on the large disk, your present selection is blinking.
