GAMX position locator; GAMX series control board
 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 manual. The terminals 34 and 35 are short-circuited for manual closing operation, and the terminals 34 and 36 are short-circuited for manual opening. 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 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.
