TERMINOLOGY

• Auto-setup Function
A function that automatically set the position that keeps constant thrust load at low-end (closed) with a single operation.
Auto-setup can be performed by following 3 types: Switching DIP SW, PU-2x, and PC configurator software (USB-Type-C).
Even if a leak occurs, the closed position can be changed in 0.1 mm.

• Modbus communication
Operation status of the actuator can be monitored during normal operation for ensuring safe operation of the product and supporting equipment maintenance.
Via Modbus communication, the following data can be monitored to grasp the operation status of the actuator.
- No. of times of start actions of the stepping motor
- No. of times of reverse actions of the stepping motor
- Accumulated operating time of the stepping motor
- Accumulated operation distance of the output stem
- No. of times of restart when an excessive thrust error occurs
- Excessive thrust error

•Excessive thrust monitoring
Function to stop the stepping motor when an excessive thrust is detected. Specifically, the unit constantly monitors the position of the output stem while the stepping motor is driven. When the unit detects that the output stem is not following the position detecting value of the potentiometer, tries to operate with max value of set thrust. If the output stem does not follow the motor after two times, an error of excessive thrust occurs and the stepping motor is stopped (alarm signal). To release the alarm signal, turn off the power voltage.

• Deadband
Linear resolution

• Hysteresis
The output stem reciprocates i.e. moves up and down according to the input signal.
Hysteresis is the difference between the two curves of ascending and descending directions, which is expressed in percentage.

• Linear Characteristics
The output stem reciprocates i.e. moves up and down according to the input signal. In theory, the output stem moves by a distance proportional to the input signal. In the case of MSP, the difference between the theoretical value and the actual distance that the output stem actually moved is expressed in persentage.

• Restart Limiting Timer
This function prevents the output stem operates frequently when the input signal is unstable.
To prevent the output stem operates frequently, it does not operate at the moment the input signal changes, but after a set period of time.

• Coil spring (thrust buffering function)
Coil supring is incorporated in the unit (output stem position).
Elasticity of the coil spring buffers thrust that affects to the valve system.

• Output stem operation distance
20 mm type means maximum operation distance.
Use 40 mm type if 21 mm of operation distance is required.
40 mm type also means maximum operation distance.
Both 20 m type and 40 mm type are max lower-end position.
Operation distance cannot be extended longer than 40 mm.
