maintenance assumes familiarity with

industrial control systems and basic electrical repair techniques, but not necessarily programmable controllers. Fault

isolation is accomplished by using module substitution techniques.

The Industrial 14 Controllers are programmed by either of two methods: Either on-line with the VT14
Programming Terminal using relay ladder diagram symbology, or off-line with a computer. Operating and
programming instructions for the VT14 are presented in the VT14 User's Manual. The Industrial 14 Software
Manual contains instructions for programming the 14's by computer.

Reference documents for the Industrial 14 Controller are listed in Table 1-1.
