Product details
◆ Overview
The OW-XDFD/Q series intelligent manual operator is a device that can replace the operator and servo amplifier in traditional DDZ automation control systems. Adopting on-chip system technology, the structure is simple, the performance is superior, the quality is reliable, and the dual digital and light column triple display is beautiful and eye-catching. It can be used in conjunction with various intelligent regulators or DCS control systems at home and abroad as a backup manual output unit for host faults and maintenance. This series of instruments is divided into: D-type operation, Q-type operation, and hard hand operation.
DThe manual controller is operated by the control signal transmitted by the regulator or DCS and the valve position signal feedback from the actuator, and directly outputs forward and reverse electrical signals to drive the electric actuator, controlling the forward and reverse rotation of the motor, and outputting the valve position signal to the regulator. When the operator switches from automatic to manual mode, the status signal of the switch quantity is output to the regulator as the valve position tracking signal for the regulator.
The Q-type manual controller calculates the control signal transmitted by the regulator or DCS and the valve position signal feedback from the actuator, and outputs a linear current or voltage signal to directly drive the pneumatic valve, control the opening and closing of the valve, and output the valve position signal to the regulator. When the operator switches from automatic to manual mode, the status signal of the switch quantity is output to the regulator as the valve position tracking signal for the regulator. Hard hand operation is controlled by an operator without automatic control, which only receives valve signals and outputs them through human-machine dialogue. The output signals can be forward and reverse electrical signals (D-type hard hand operation) or linear current and voltage signals (Q-type hard hand operation). And by receiving the valve position signal, the valve position is displayed to determine the valve opening.

◆ Characteristics
The input signal can be arbitrarily specified and selected.
● Automatic startup or manual startup first (can preset manual output values).
● Manual state output.
Valve position feedback tracking output.
EM l-process manual function, the initial output value remains unchanged, and after remote manual cancellation, it can remain manual or return to automatic mode.
EM2 manual function, with preset initial values.
Valve position feedback error indication, valve position feedback disconnection can be automatically switched to manual mode.
● Tracking error error indication.
When the main input is disconnected, the control signal automatically protects the motor and outputs a fault signal.
Two channels of 1 6A or 4 1A bidirectional thyristors can be built-in in the table to directly control the forward and reverse rotation of the motor of the actuator.
All setting parameters can be saved and lost up to 10 times.
The system automatically resets without any crashes.
