Cylinder Setting 

The  first  screen  displays  the  essential 
functions of the EPS 02 and ties the actuator 
specific  parameters  to  the  sensor  unit.  In 
most  cases  the  following  parameters  are 
already  factory  set.  Starting  at  the  left  hand 
corner: 

Cylinder  max  Stroke:

  Nominal  stroke 

length  of  the  purchased  actuator  in 
millimeters. 

Number of Motor Turns for max Stroke:

 

This value represents the number of rotations 
at the EPS 02 sensor head to account for the 
full nominal stroke of the actuator. 

Clockwise 

or 

Counter 

Clockwise 

Direction: 

The  physical  location  of  the 

EPS02  position  sensor,  in  the  “A”  or  “D” 
accessory housing, “C” design or number of 
stages in the utilized gearbox if so equipped, 
decides the direction of rotation at the sensor 
head  in  relation  to  the  stroke  direction.  A 
counting  direction  will  be  selected  with  the 
radio buttons. 

External  Reference  Function: 

If  an 

external  reference  switch  is  used,  this 
selector  box  will  be  enabled.  The  positive 
edge of the external reference switch will set 
the absolute position to 0mm. 

Input Status Display Windows: 

The below 

six input status display windows indicate the 
binary input channel conditions: 

 

 
-  Push Button S1, S2 (EPS02 only) 
-  Input 1, 2; Time Delay Extend /  
                     Retract 
-  Input 3; External Reference Switch 
-  Over Temperature Switch

 

Set  Zero Position: 

In the center of the 

screen,  below  the  angular  rotation 
display,  the  set  zero  push  button  is 
located.  By  pushing  this  button  the 
absolute position will be set to 0mm and 
stored  in  the  battery  backed  up  RAM. 
The factory set zero position represents 
the physical retracted end position. This 
position should never be reached under 
normal operating conditions.  

Sensor Misaligned: 

If the distance or alignment between the 
sensor  head  and  the  rotating  magnet  is 
out of range the normally gray field will 
turn purple. 

Speed 0 RPM:

 Displays the RPM value 

on the sensor head. 

Read  Parameter  Block  /  Send 
Parameter  Block: 

By  pressing  the 

button read or send parameter block, the 
upload  or  download  RACO  Tool 
software  function  will  be  initiated  and 
all parameters will be exchanged via the 
USB  and  /  or  TTL  communication 
interface between the EPS 02 and  the
