12.2.2 Reprogramming the setpoint range, final
positions and control direction
Setpoint range
In the factory settings, the setpoint range is set to
4-20 mA.
To change from 4-20 mA to 0-20 mA:
1. Disconnect the power to the servomotor.
2. Hold the SET and R buttons down.
3. With the buttons held down, switch the supply
voltage on.
To change from 0-20 mA to 4-20 mA:
1. Disconnect the power to the servomotor.
2. Hold the SET and L buttons down.
3. With the buttons held down, switch the supply
voltage on.

Final positions
In the factory settings, the left (max.) final position is
set to 100 % stroke at 20 mA and the right (min.)
final position to 0 % stroke at 4 (0) mA.
To reprogram the left final position:
1. Set the Man/Auto DIP switch to "Man".
2. Use the L/R buttons to approach the required left
final position.
3. Press the SET button (blue LED flashes) and then
press the L button within 3 seconds.
– The newly set left (max.) final position at 20 mA
has now been programmed.
To reprogram the right final position:
1. Set the Man/Auto DIP switch to "Man".
2. Use the L/R buttons to approach the required
right final position.
3. Press the SET button (blue LED flashes) and then
press the R button within 3 seconds.
– The newly set right (min.) final position at
4 (0) mA has now been programmed.
Effective control direction
In the factory settings (or after the final positions
have been programmed), the left final position is set
to 100 % stroke (or the newly programmed max. final
position) at 20 mA and the right final position to
0 % stroke (or the newly programmed min. final
position) at 4 (0) mA.
To reverse the effective control direction to 0 (4) mA
at the left final position and 20 mA at the right final
position:
1. Set the DIP switch to the "inv" (inverse) position.
To reset the effective control direction to 20 mA at
the left final position and 0 (4) mA at the right final
position:
1. Set the DIP switch to the direction opposite to
"inv" (not inverse).
Completing programming work
1. To complete programming work,
set the Man/Auto DIP switch to "Auto".
2. Close the hood again and tighten the hood
screws.

12.2.3 Error message

• Error message output: Terminals 56, 57
• Maximum permissible load: 125 V
• Red LED lights up if a contact is open.
The error message contact opens in the following
instances:
• If there is a setpoint violation: I
mode 4-20 mA).
• If the "Manu/Auto" switch is set to the "Manu"
position (controller in programming mode).
• If there is no operating voltage.
