ACCURATE
the position of the servo-
motor is proportional to the control voltage, between 0 and 10
Vdc. The servomotor stops:
- automatically at the end of its travel;
- in the position of equilibrium, corresponding to the control
voltage;
- in the current position, when cutting off power.
OPERATION OF THE MVX52 - 0÷10V SERVOMOTORS
The opening of the valve can be controlled by checking the posi-
tion using the indicator located on the top of the servomotor
EMERGENCY MANUAL OPERATION
