Communication parameters can only be changed after the key number has been entered. Special version with three-key operation is available. The actuator version with three-key operation allows the set point to be changed and displayed on the start screen in 'PID controller' and 'Temperature closed-loop control upon input signal failure' applica- tions.
Design and principle of operation 3 Design and principle of operation The Type 3374 Electric Actuator is linear actuator, which is used in combination with SAMSON valves in industrial plants as well as in heating, ventilation and air-conditioning systems. The force of the stepper motor is transmitted to the actuator stem over gearing and a ball screw drive.

Appendix A (configuration instructions) 16 Appendix A (configuration instructions) 16.1 Key number To change parameters in the configuration level, a key number can be activated in the actuator over Code c94. When the key number function is activated, the key number must be entered before the parameter setting can be changed. If a code is selected without entering a key number beforehand when the key number function is activated, LOCK is displayed and the parameter settings cannot be changed.
Appendix A (configuration instructions) Example: Two valves regulate the process medium in one common pipeline to achieve a large rangeability. For example, one valve opens with a 0 to 5 V input signal, while the second valve also opens when the input signal increases further (5 to 10 V) and the first valve remains open.
Appendix A (configuration instructions) 16.4 End position guiding Direction of action: increasing/increasing – Value above limit (end position guiding) (c35): The actuator stem moves the valve to the top end position if the input signal reaches the 'Value above limit (end position guiding)'.
Appendix A (configuration instructions) – Inactive (c11 = NONE): No function is assigned to the binary input. – Priority operation (c11 = PRIO): The priority operation is triggered and the actuator stem moves to the position entered in Code c34 as soon as the binary input changes to the active switching state.

Appendix A (configuration instructions) – Fixed positioning value (c43 = FIX): The actuator switches to the manual mode and moves the actuator stem to the Fixed positioning value for restart. – Stop in manual level (c43 = STOP): The actuator switches to the manual mode and sets the last positioning value to be the same as the manual positioning value. Code Description Default...

The dead band represents the sum of the positive and negative hysteresis. After the actuator has been stationary, the input signal must change by at least half of the dead band to cause the actuator stem to move again.

For example, a set point deviation of 5 °C and a proportional-action coefficient of 2 results in a travel of 10 %.
