Operation of the Programming Interface ETA25PS

Solder lugs, 5-PIN, Contact
Spacing 2,54mm

Programming Procedure:

A. Before you connect the supply voltage:

1. Configure DIP-Switc h 1: Chose supply Voltage (5V (24V / 3.3V)). (*) In case that 24V supply
voltage version was ordered it is not allowed to switch DIP switch 1 to 3.3V position.

2. Configure DIP-Switc h 2: Chose sense of rotation (rising output signal in CW or CCW direction
 please see drawing on the right hand)

3. DIP-Switches 3 and 4 must be set both in OFF-Position

B. Program m ing the start- and end position:

1. Connect power supp l y voltage

2. Switch DIP-Switch 3 to ON-Position (programming mode)

3. Put the shaft to start position and set DIP-Switch 4 for > 1s to ON and then back to OFF

4. Put the shaft to the end position and set DIP-Switch 4 for > 1s to ON and then back to OFF

5. Switch DIP-Switch 3 to OFF-Position (measuring mode)

- The change of the sense of rotation (CW / CCW) and the supply voltage (5V / 3.3V) can be

- The programming switches 3 and 4 are out of function after programming.

The adjustment of the start- and end position by means of the DIP-Switch programming
procedure can be proceed only once (OTP).
