Signal behaviour
:
ENABLE 24V
: This function allows the valve control when voltage power supply interrupts
(Fail save); the output current pressure is not modified.
Servovalve control Interbus input
: This function allows the servovalve piloting to be
done through the Interbus control input (Active High = ENABLE goes to 0V ->): pressure
stays unchanged.
