The T2050 is a fixed-sequence control. This means that it executes
all program instructions in order, and it executes all instructions.
If you do not wish to use a function or instruction (such as
steppers), you must program it to a value of 0.
Two types of instructions can be entered with the Data Entry
Panel (DEP).
• The first type is a Sequence instruction. Sequence instructions
control valves and weld heats when the control is initiated.
All sequence instructions are located in the left-hand column
of the DEP.
• The second type of instruction is called a Configuration
instruction
. A Configuration instruction controls global
functions that are common to more than one schedule or
weld heat. All configuration instructions are located in the
right-hand column of the DEP.
To select an instruction to program, press the
E
key directly
under the instruction's column on the DEP (Figure 4 on page 5-
16, Items 5, 6). The LED directly above the column will light to
indicate which column is active (Figure 4 on page 5-16, Items 2,
4). The instruction indicator LEDs in the center of the data entry
panel (Figure 4 on page 5-16, item 3) shows which instruction you
are currently editing. Repeatedly pressing the
E
key under a
column moves the instruction indicator LED down the column,
allowing you to edit new instructions. The numeric display
shows the value of the item you are editing.
