To get the unit into the editor mode, perform the dual-key
operation [Shift][Setpt.] The PROCESS window will have the
message EDIT displayed and the SET window will have a
XXXX displayed signifying the program number to be edited.
At this point any of the 200 programs can be called into the
edit space using the arrow keys to change the necessary digits.
That is, the [left arrow] or [right arrow] keys can be used to
select the digit to be changed and the [up arrow] or [down
arrow] keys can be used to select 0 through 9.
Next, press the [Enter] key once more to begin entering or
modifying the program. The PROCESS display will show step
01. The OPCODE character is also displayed in the PROCESS
display while the SET display will show the DATA line in
various formats depending on the OPCODE character. To
advance through each step of the program use the [Enter] key;
to move backwards in the program use the [Shift] key.
At any point, a step can be inserted or deleted. To insert a
step, press Control Parm, this forces the OPCODE at step 19 to
be lost and a -(NOP) will appear. To delete a step, press
[Alarm Set key], this causes a - NOP to be pulled in at step 19.
Use the [left arrow] or [right arrow] keys to determine whether
the OPCODE or DATA is to be changed. If a data character is
flashing move left or right in the data by using the arrows. If
the OPCODE needs to flash press the [left arrow] until the
OPCODE character flashes the [right arrow] does not allow
access to the OPCODE. If the OPCODE is to be changed, the
[up arrow] or [down arrow] keys can be used to scroll through
the OPCODES alphabetically. If either the "up arrow" or
"down arrow" keys are held down, the OPCODEs will
automatically be displayed with each flash of the display.
When entering data, the "up arrow" and "down arrow" keys
can be used to select 0 through 9 (or negative sign, if
applicable).
