Note : Counter or totaliser reset may also be achieved by pressing the 'Enter' key (press for 3 seconds). External reset is almost instantaneous.
Note : The "special" (SP) input is normally configured for potentiometer input. It can however be configured to order as per customer's requirements.
Note : For 2- wire NAMUR sensors, the proximity switch must be able to operate from 5V supply.
Place hardware links as shown in the diagrams.
Remember : Configuring this instrument requires two steps. (1)
Select the correct hardware links as shown. (2) Program the
instrument with the programming chart on page 8 & 9.
