1. Congratulations on your wise choice to purchase a T6 programmable sequence controller It s pow erful yet surprisingly easy to program There isn t much that you ll need to learn the T6 uses En glish as its language too Please take some time out to read this short manual Just one wrong con nection could get your project off on the wrong foot The T6 is designed and manufactured in the United States by Trol Systems Incorporated TSI specializes in simplifying industrial automation by devel oping unique products that are easy to understand Our best advertisement is by word of mouth So if you find the T6 to be a product that is simple to use at a great price please tell others about it That will help them out and us too Future development of new products is largely based on our customer s requests and concerns We value any comments and sugges tions that you may have so please let us know Additional information about the T6 including a copy of this manual is avail able on line at www trolsystems com If you should need help with the T6 contact your distributor If you have a technical question that your distributor can t answer we offer free factory direct support from 9AM to 4PM EST Monday through Friday Our techni cal support number is 717 939 7593 Fax 717 939 5831 or E mail Eng trolsystems com You program the T6 by selecting functions that form lines of a page The program looks similar to2. And don t worry all devices in the T6 system use a type of memory that does not require power or batteries If you re concerned that someone might try to mess up your program consider locking the program with a pass word Use the Setup Menu for that Let s take a quick look at the program mer DISPLAY asks you to choose a menu then asks you to make selections from that menu Prompts that end with a mean Aalto RONS that other choices are available ENTER stores the currently dis played selection then proceeds to the next prompt UP DOWN makes choices from the menu The choices will scroll past at a faster rate when the button is held down BACK cancels the last selection Pressing Back again will open the EDIT menu so that you can correct a mis take on any line of your program Pressing back again will return you to the current line in the Program Menu Before we proceed to write a program take a lined sheet of notebook paper and at the top write Page A Then number the lines of the sheet As you program each line remember to write it down This will help you keep track of where you are and how your sequence occurs Then if any changes need to be made editing will be a snap First the programmer must be given power Should you run out of pro gramming time just turn off the power and you will be prompted to finish from where you left off the next time power is applied The progra
