2301A 9907-018 WOODWARD 正向动作速度控制

The 9907-018 model is a low-voltage model, it operates as a single actuator system, and is not offered with a deceleration ramp. The model is also a forward-acting control and operates on an actuator current of 0-200 mA and is CE approved. The voltage source of a low-voltage model is in the range of 20-40 Vdc. 

With the low voltage model be sure that when connecting shields to the control you absolutely under no circumstances use terminal zero, non-use is indicated on the front of the frame of the control.  The contact used to give the prime mover a positive dc source is terminal sixteen, this terminal is also interlocked with terminals fourteen, seventeen, eighteen, nineteen, and thirty, these terminals are also the dc supply and positive connecting point.

The actuator compensation potentiometer on the control is typically used as a means to stabilize the control and prime mover. If during use there is an extreme instability or the control is unusually overactive decrease the actuator compensation by very slowly turning the potentiometer clockwise. The actuator compensation potentiometer can be set fully counterclockwise if needed, but be cautious when doing so not to over-torque the pot.

If during operation you are adjusting the gain potentiometer and there is a temporary change in speed on the prime mover the adjustment was likely made too quickly, to fix this make sure that the adjustment is made slowly instead.
