Bernard Position Power Board Electric Actuator Controller Gamx-2004 - China

(1) Automatic control

1 - Input signal: 4-20mA

2 - Output signal: 4-20mA

3 - Automatic control: Standard: 4mA valve close, 20mA valve open.

Reverse direction: 4mA valve open, 20mA valve close.

4 - Interrupt persist: standard：when loss signal, the actuator maintain original position.

Non-standard: when loss signal, the actuator close.

Non-standard: when loss signal, the actuator open.

5 - Dead zone: Through the dead zone potentiometer P3 to adjust.

Dead zone range: 0-3% mean 0-480μA

6 - The machine running automatically: the machine running automatically makes the locator simulate a 4-20mA input signal, making actuator running.

7 - 0% adjustment: locator 0%, makes the actuator receive 4mA close command.

8 - 100% adjustment: locator100%, makes the actuator receive 20mA open command.

(2) Remote control: 1 - The remote control for passive dry contact control, In the case of dry contact control, it can make the actuator receive the pulse remote command.

Complete valve opening and closing.

Remote control prior to the automatic control, when controller in remote position, automatic control were blocked, don't work.

2 - The operation of the actuator

Standard form: Actuators for output shaft clockwise to open it.

Through the dial switch can change control(Change the direction of motor rotation), Make the actuator counterclockwise to open it, Change the limit switch and torque switch direction at the same time.

3 - The electric brake configuration

One phase power(220V AC) Configure electric braking.

Three phase power(380V AC)make the plate electric braking function doesn't work through the dial switch, Actuator electric braking performed by external circuit.

(3)LED indication:

LEDI (green) actuator on LED2 (red) actuator off

LED3 (red) loses 4-20mA signal LED4 (red) over torque switch action

LED5 (red) electric brake works, the brake light flashes instantly

二, Use

1 - Dial switch DIL：

Loss 4-20mA input signal is not failure, also not protected

Electric braking malfunction

When loss 4-20mA input signal, valve close

When loss 4-20mA input signal, valve open

Actuator for reversing, facing the output shaft counterclockwise to open it, Should be exchange sampling switch potentiometer1, 3head at the same time.

That is DXK in the locked position

2 - Slide switch COMV

(Remark: if actuator used with DFD1900, The operator must in automatic position

If the operator in manual position, also the operator use the COMA in spot, can be temporarily removed wiring 34 or 39

Locator working in the automatic position

Locator working in the 0%position

Locator working in the 100%position

Locator working in the machine automatic position, At this point with PI regulation

3 - P1: When adjust PI, clockwise for the valve closed, anticlockwise for the valve open, now COMV must in position 4 - P2: 100% full scale adjustment

5 - P3: Dead zone adjusting ref: adjust p3 make BM point potential is 1.3VDC, dead zone both for 200μA

6 - P4: Working point adjustment: make A point potential is 5VDC±0.001V, Potential point A has been adjusted well before leave the factory, without user adjust.

7 - A short way INV1 4mA valve close, 20mA valve open 4mA valve open, 20mA valve close

8 - Test Point: 1)12V: 12v

2)A: 5V ±0.001V

3)BM: 1.3V

4)D: 1-5V change

5)OV: OV

Remark: GAMK-2004 Outside the panel wiring and GAMXX941 panel wiring are identical.
