6.3 System Values
Feedback
Value indicating the actual actuator position based on an analogue signal
Command Signal
Value indicating the required command position based on a 4-20mA analogue signal
Remote Command
Value indicating a user specified required command position
Open Limit
Value indicating the position at which the actuator is deemed to be fully open
Close Limit
Value indicating the position at which the actuator is deemed to be fully closed
Open Static
DZ
Value indicating how much the command signal must be greater than the feedback position,
when the actuator is static, before it starts to open
Open Moving DZ
Value indicating how much the feedback signal must be less than the command signal, when
the actuator is opening, before it becomes static
Open Pulse Zone
Value indicating how much the feedback signal must be less than the command signal, when
the actuator is opening, before it starts pulsing the open solenoid
Close Static DZ
Value indicating how much the command signal must be less than the feedback position, when
the actuator is static, before it starts to close
Close Moving DZ
Value indicating how much the feedback signal must be greater than the command signal,
when the actuator is closing, before it becomes static
Close Pulse Zone
Value indicating how much the feedback signal must be greater than the command signal,
when the actuator is closing, before it starts pulsing the close solenoid
Accum Pressure
Value indicating the accumulator pressure based on an analogue signal
Low Pressure SP
Value indicating the pressure at which a low accumulator pressure fault will be raised
Pump Start SP
Value indicating the pressure at which the pump starts to run in order to build pressure in the
accumulator
Pump Stop SP
Value indicating the pressure at which the pump is stopped due to the correct pressure being
present in the accumulator
High Pressure SP
Value indicating the pressure at which a high accumulator pressure fault will be raised
Supply Pressure
Value indicating the hydraulic supply pressure based on an analogue signal
Min Supply Px SP
Value indicating the pressure at which a low supply pressure fault will be raised
