4. Press the ENTER key.
The display will show a new screen 
containing the option title 4-20mA INPUT 
on the top line and a 7 digit number with the 
leftmost digit flashing as a prompt for input. 
The 4-20mA input will be converted by the 
controller to pulses, proportional to the span 
of the input, at the rate set in the 
specifications. To set the number of pulses 
required to be input before a sample program 
is started, use the ARROW keys to move 
the flashing prompt until it is over the digit 
requiring change. 
Press a number key (0-9) to replace any 
existing number and advance the flashing 
prompt to the next digit to change. Replace 
digits as required, then press ENTER. 
The display will echo the last entry with 
<ENTERED>. 
Any wrong entries will require re-entry. If 
ENTER has not been pressed, reposition the 
flashing prompt over the incorrect digit and 
replace it. After ENTER has been pressed, 
the entire entry must be redone from the 
beginning (press SET). 
The controller has now been given a new 
value for START DELAY. The new values 
reside in the NEW ENTRIES area of the 
controller memory. To make these changes 
active, press the RESTART key; press it 
again to confirm your choice. The controller 
will then wait until the required pulses have 
been received before starting its sampling 
program
