Programming 

 

a.

 

Programming Overview 

The programming ring can be rotated from the Neutral center position to 
Position 1 and Position 2. The following actions are possible: 
 
A – Display of parameters with Position 1 (simultaneous display of the 
set parameters) – 

Turn the programming ring left to Position 1 to begin 

cycling through these programming parameters: Switching points S1 and 
S2, Hysteresis direction of S1 and S2, Hysteresis Hyst 1 and Hyst 2, Code 
(allows editing of additional parameters), Filter, Units, Output, 4 mA Value 
and 20 mA value. See following pages for detailed programming 
instructions. 
 

B – Editing with Position 2 

Turn the programming ring to the right to 

Position 2 and a flashing cursor appears showing the position to be 
changed. With repeated turning to Position 2, the values are increased. By 
turning to Position 1, you obtain the next position. Each position can be 
edited in this way. If there is no action within 5 seconds, the device 
returns to the normal display section without the change being 
accepted, and you will have to cycle through the program again. 
 

C – Saving the change with Position 1 

Turning one time toward Position 

1 after quitting the last value signifies acceptance of the change. 

 

b.

 

Programming Protection 
The programming ring can be pulled off, inverted, and replaced. This will 
prevent further programming resulting from turning the ring in either 
direction. (See Protecting your Programming Parameters section.)
