GAMX-2007 Bernard Electric Actuator
Position locator isolation module instruction manual

First, the  main technical parameters
1, input signal: 4-20mA 2, input resistance 250 ohms
3, the output signal: 4-20mA, the input signal and the output signal are isolated, the user does not need to isolate the module
4, output resistance: 0-500 ohms (special need 0-750 ohms)
5. Feedback potentiometer: 0-1K ohm 6. Basic error: ±1%
7, dead zone: 0-3% adjustable 8, power supply voltage: 220V ± 10%
9, ambient temperature: -25 ° C - +55 ° C 10, relative humidity: ≤ 90% (no condensation)
Second, the  main function
1.  Operation mode: Forward: 4 mA valve is closed, 20 mA valve is open Reverse: 4 mA valve is open, 20 mA valve is closed.
2.  Interrupt hold: When the signal is lost, the actuator can remain in the home position, closed or open, and the interrupt signal setting actuator remains in the home position at the factory.
3.  Manual operation of the machine: The manual operation of the machine is to make the positioner simulate a 4-20 mA input signal, so that the actuator can be manually adjusted to fully open or close.
4,  0% position: positioner 0%, so that the actuator is fully closed.
5,  100% position: the positioner is 100%, so that the actuator is fully open.
6.  When the terminals 19 and 34 are shorted , the automatic control is turned off, and the manual is turned into the short circuit. The terminals 34 and 35 are manually turned off, and the short terminals 34 and 36 are manually opened. Remote control takes precedence over automatic control. When the controller is in the remote control position, the automatic control is blocked and does not work. The remote control is jog.
7,  actuator running direction:
In standard form : the actuator (for the output shaft) is turned clockwise
The DIP switch can be used to change the control (change the direction of motor rotation) to turn the actuator counterclockwise and change the direction of the limit switch and torque switch.
      8, electric brake configuration: GAMX-2005 module 220VAC and 380VAC universal
Single phase power supply ( 220VAC) with electric brake
The three-phase power supply ( 380VAC) makes the electric brake function ineffective through the dial switch, and the actuator electric brake is completed by the external circuit.
9,  LED instructions:
LED1 ( red) power indicator      LED 2 (green) actuator on        LED3 (red) actuator off
LED4 (red) loses 4-20mA signal LED5 (red) over torque switch
LED6 (red) electric brake works, the brake light flashes instantly
10.

Use of DIP switch DIL

11,

Slide switch COMV implements four states

12,  P1 : adjust P1 clockwise to adjust the valve to close, counterclockwise to open the valve, at this time COMV must be in theMAN position
13,  P2 : 100 % full scale adjustment. Adjust the feedback current clockwise to increase, at this time COMV is in the AUTOposition.
14,  P3 : dead zone adjustment reference value: clockwise adjustment P3 , dead zone increase, low sensitivity, counterclockwise adjustment P3 dead zone reduction, high sensitivity, actuator in the automatic adjustment state, adjust the P3 potentiometer to make the actuator The best state is when the vibration is not oscillated and the highest sensitivity is reached. At this time, theCOMV is in the AUTO position.
15,

Short circuit sub- INV1

Third, the debugging method:

The actuator works in the machine to automatically adjust the working state, use the remote control terminals 34 , 35 , 36 to fully close the actuator, adjust the position potentiometer, make the feedback current 4mA , make the actuator fully open, adjust the full potentiometer P2 makes the feedback current 20mA , repeat the above operation several times, until the actuator is fully closed corresponding to the feedback current 4mA , fully open corresponding to the feedback current 20mA .
