2.1 Full Chinese menu
High resolution dot matrix LCD display, with ultra large digital real-time display of valve opening size, full Chinese display of operation menu, and real-time Chinese display of alarm information and working status according to working conditions; The high brightness LED light emitting tube indicates the limit position of the valve's opening and closing.
2.2 Multiple control methods
2.2.1 On site control
When the "mode selection knob" is in "field", the "operation knob" or "infrared setter" can be used on site to control the opening or closing of the valve. On site operation can be set to "jog" or "hold" control mode.
2.2.2 Remote switch quantity control (also known as remote manual control) When the "mode selection knob" is set to "remote", the switch quantity control has three input terminals, namely open valve, close valve, and stop/hold; Switch control can be achieved through external wiring to achieve "hold" or "jog" control.
2.2.3 Remote current control (also known as remote automatic control) (adjustable type)
When the "mode selection knob" is in the "remote" position, users can control the operation of the actuator through a 4-20mA current to achieve precise positioning of the valve.
2.2.4 ESD control
In emergency situations, ESD signals can override any on-site or remote signals, forcing the actuator to either "close" or "open" the valve. ESD can be selected to be effective at high or low levels, and can also choose whether to exceed motor overheating or to exceed intermittent operation control by pressing the stop button.
2.2.5 Fieldbus control (also known as remote digital control)
The FIQ series actuators have the ability to accept fieldbus control. The actuator can meet the control requirements of the Modbus bus. If this feature is required, please specify it when placing an order.
2.2.6 Two line control
The FIQ series actuators have the function of two wire electric operation. Can achieve special control requirements of "open with signal, no signal" and "open with signal, no signal".
2.2.7 Intermittent operation control
Intermittent operation refers to the operation process of the actuator not being continuous, but rather running and stopping. This operation is designed for those who require clearance actions during valve opening or closing. Intermittent operation allows the actuator to perform off/on actions in a pulsating manner, effectively increasing travel time to prevent hydraulic shock and fluid surge.
2.3 Comprehensive protection functions
2.3.1 Valve position limit protection
The actuator automatically stops when it reaches the closing and opening limit positions.
2.3.2 Torque overload protection
Used to prevent torque overload during actuator operation. This function protects both the valve and the actuator itself.
2.3.3 Automatic phase sequence adjustment
The actuator automatically detects the phase sequence of the three-phase power supply connected to the power terminal, and through appropriate logical operations, determines which AC contactor to excite during the actuator operation to ensure the correct phase sequence rotation is connected to the motor. Users do not need to consider the phase sequence of the wiring for the actuator power supply.
2.3.4 Instantaneous reversal protection
When the actuator receives a command to move in the opposite direction, a time delay is automatically added to prevent unnecessary wear on the valve shaft and gearbox.
2.3.5 Power supply phase loss protection
The actuator has a reliable power phase protection function. When the power supply is out of phase, the motor is prohibited from running to avoid overheating caused by out of phase operation.
2.3.6 Action when the valve is stuck
Regardless of whether the actuator operates in the open or closed direction, the torque protection function is temporarily disabled within 0.2-0.3 seconds after the excitation motor signal is sent out; In the fully closed position, the actuator moves in the open direction and temporarily inhibits the torque protection function for 3-5 seconds after sending a signal to excite the motor, thereby achieving the release of valve jamming.
2.3.7 Motor overheating protection
A thermal relay is installed at the end of the motor winding to directly detect the temperature of the motor winding. When the thermal relay detects overheating of the winding, the control circuit will inhibit the action of the actuator.
2.3.8 Electrical isolation protection
The input and output channels of the actuator that are connected to the outside world are all optoelectronic isolated, ensuring the reliable operation of the actuator without interference.
2.3.9 Protection of the box
The box is equipped with an O-ring at the static fit and a skeleton oil seal at the dynamic fit, achieving a protection level of IP67. The explosion-proof box can be suitable for hazardous working environments such as Zone 1 and Zone 2 in IIA and IIB T1-T4 explosive gas environments. If explosion-proof function is required, please specify it when placing an order.
2.4 Absolute Encoding Position Sensor
The FIQ series actuator adopts a multi turn absolute coding position sensor, which adopts photoelectric coding measurement and has strong resistance to electromagnetic interference. After power failure, there is no need for battery support to maintain the valve position unchanged. The valve position is always correct and has extremely high reliability.
2.5 Torque can be displayed in real-time and set arbitrarily
The FIQ series actuator can measure the current torque of the actuator in real time and display it in real time. Users can set torque protection values on site through the menu, effectively protecting the valve.
2.6 Non open cover debugging
Working parameter settings and system status queries can be completed through the operation knob or infrared setter, without the need to open the electrical cover, preventing harmful substances such as dust and moisture from entering the interior of the actuator, greatly improving the reliability of the electrical control part.
2.7 Power failure without loss status indication
The on-site configurable bistable output contacts can indicate various states of the valve (including switch limit, over torque, operation indication, or valve opening to a certain position, etc.), and the output state can remain unchanged even when the system is powered off.
2.8 Self locking
The self-locking design of the worm gear and worm gear prevents the actuator from reversing in the event of power failure or signal interruption.
2.9 Automatic clutch reset
Featuring a unique mechanical manual/automatic switching mechanism, manual operation is achieved by pulling the switching handle. Once the motor receives an electrical signal to start, the clutch can automatically reset and restore the actuator to automatic mode.
2.10 Operating the handwheel
The design of the handwheel ensures emergency operation of the actuator in the event of a power outage.
2.11 Motor characteristics
A single-phase or three-phase fully enclosed squirrel cage induction motor configured according to power requirements, with high starting torque and small moment of inertia.
