Brief Introduction
Input signal is 4-20ma or passive switch signal(without external contact with the power signal).
output signal is 4-20ma, complete isolation between the input channel and output channel.
When the input signal for the passive contact signal(see picture 6 terminal,34,35,36,39), Which can be controlled electric remote control type of the actuator. There are manual and automatic switch TS on circuit board; when is on manual position, Turning PI potentiometer knob can be operated actuator running.
Logic signal type setting: Jump line RT used to determine,
(1)When on RT position, when loss input signal, the actuator hold original position
(2)When on RT position, when loss input signal, the actuator closed
(3)When on RT position, when loss input signal, the actuator fully-open
Change in the direction of running, running direction determined by key switch IT1&IT2
(1)Actuator leave factory run by a clockwise direction. key switch IT1&IT2 keep original position(Switch in the free state),4ma is vavle closed,20ma is vavle open.
(2) press the key switch IT1&IT2 at the same time(Switches are locked in the press); Actuator counterclockwise running,4ma is vavle open,20ma is vavle closed.
Full adjustment:P2 is full adjustment;
Dead zone adjustment:P3 is dead zone adjusted potentiometer, adjustment range is 0.3-3%,it has been set well when leave factory. It will be adjusted when need again.
·circuit board point A and point D reference point adjustment. Potential of point A and point D has been adjusted well when leave the factory. The user do not adjust, general condition, when input signal is 4ma, an be achieved by adjusting P4 potentiometer that make potential of point A is 5V.DC,the user don't adjust P5
