An example of the first display screen is shown below:
SYSTEM STATUS
The system status information line is used to provide
details on the controller status and any faults that are
currently present. Below are the statuses that can be
displayed:
Healthy
- System is healthy and there are no faults
present
Feedback Fault
- Feedback signal is in fault
Command Fault
- Command signal is in fault
Common Fault
- External common fault is present
Pump Fault
- Pump is in fault
Overrun Fault
- Pump has run continuously beyond its
maximum allowable time
Low Level Fault
- Pump reservoir level is below the
level switch set point
High Temp Fault
- Pump reservoir temperature is
above the temperature switch set point
Acc Press Fault
- Accumulator pressure signal is in fault
Low Press Fault
- Accumulator pressure is below
minimum allowable pressure
High Press Fault
- Accumulator pressure is above
maximum allowable pressure
Low Supply Press
- Supply pressure is below minimum
allowable pressure
Supply Press Flt
- Supply pressure signal is in fault
ACTUATOR STATUS
The actuator status information line is used to provide
details on the current movement of the actuator. Below
are the statuses that can be displayed:
Stayput - Actuator is stationary
Opening
- Actuator is opening
Closing
- Actuator is closing
Open Limit
- Actuator is fully open
Close Limit
- Actuator is fully closed
Pump Output
- Pump is running
ACTUATOR POSITION
Provides the current actuator position based on the
analogue signal. If the signal is in fault 0.0% will be
shown.
COMMAND
Provides the demanded actuator position. If in 4-20mA
command control the 4-20mA signal will be displayed. If
in remote command control the remote command signal
will be displayed. If the signal is in fault 0.0% will be
shown.
CONTROL INPUT
The control input status line is used to indicate what is
currently driving the actuator and aims to show why the
actuator is in its current state. Below are the list of
possible control inputs:
None - There is no control input so the actuator will be
stationary
4-20mA Cmd Ctrl
- Modulating based on the 4-20mA
command signal
Remote Cmd Ctrl
- Modulating based on the remote
command signal
Remote Open
- Opening due to a digital signal
Remote Close
- Closing due to a digital signal
Override Open
- Opening due to a digital signal and is
overriding a fault
Override Close
–
Closing due to a digital signal and is
overriding a fault
Manual Open
- Manually opening using the switch
Manual Close
- Manually closing using the switch
Fdbk Fault Open
- Faulting open due to a feedback
fault
Fdbk Fault Close
- Faulting close due to a feedback fault
Fdbk Fault Stop
- Faulting last due to a feedback fault
Fdbk Fault Stay
- Faulting last due to a feedback fault,
but the standard fault position is either open or closed.
Cmd Fault Open
- Faulting open due to a command
signal fault
Cmd Fault Close
- Faulting close due to a command
signal fault
Cmd Fault Stop
- Faulting last due to a command signal
fault
