c. Proportional Card Settings
• Control Signal Selection
Control signals are selected with the INPUT switch shown in Figure 13. Proportional electric

selection can be made according to Table 4 by changing the pins of the INPUT switch.
• Output Signal (Feedback) Selection
Output signal selection is made with the OUTPUT switch shown in Figure 14.
Proportional electric actuator is set to 4 - 20 mA output signal as factory setting. Output
signal selection with OUTPUT switch is shown in Table 5.

• Error Positions
When the input control signal connected to the proportional electric actuator is interrupted
for any reason, the actuator behaves according to the pre-set action with the SETTINGS
switch. In the loss of signal, there are 3 different settings: keep the valve in its position,
open the valve and close the valve. As the factory setting, the valve is set to remain in its
