Abstract
A system for checking high fluid pressure and low fluid pressure limit switches for valves and fluid supply to a fluid consumption appliance. The system may incorporate one or more pressure sensors at a fluid valve to detect an amount of fluid pressure. The one or more pressure sensors may be connected to a processor. The high fluid pressure and low fluid pressure sensor limit switches may also be connecter to the processor. A display and user control may be connected to the processor.
Claims20
A system for setting up a valve comprising:
- a display screen having a control interface;
- a gas valve having an actuator;
- a pressure sensor at the gas valve;
- a processor connected to the actuator, pressure sensor and the display screen;
- and
- wherein:
- the display screen comprises:
- an indication of current operating pressure;
- a first icon representing a first limit switch;
- a second icon representing a second limit switch;
- and
- a graph revealing an indication of operating pressure over time;
- and
- wherein:
- the first icon is moveable along a bar for testing a low pressure limit setpoint of the first limit switch;
- and
- the second icon is moveable along the bar for testing a high pressure limit setpoint of the second limit switch.
A method for setting up a valve, comprising:
- connecting a display to a processor;
- and
- connecting a pressure sensor to the processor, to sense fluid pressure at a valve;
- and
- wherein:
- the processor constructs a first switch icon on a screen of the display to represent a low gas pressure limit switch, and a second switch icon on the screen to represent a high gas pressure limit switch;
- the processor inserts a first setpoint indicator on the screen for a low gas pressure limit switch, and a second setpoint indicator on the screen for a high gas pressure limit switch;
- and
- the processor places an operating pressure icon on the screen upon which the first and second switch icons are moveable for testing a setpoint for the low gas pressure limit switch and testing a setpoint for the high gas pressure limit switch, respectively.
A mechanism for a valve setup comprising:
- a processor;
- and
- a display showing a screen as a user interface connected to the processor;
- and
- wherein the user interface comprises a slider bar that has a limit icon representing a limit switch that has a pressure setting, and the limit icon can be moved along and past a point representing an operating pressure of fluid to a valve for verifying that a limit switch with that setting, has tripped for locking out a system having the valve for controlling a flow of fluid, and as soon as the limit switch has tripped during a test mode, the pressure setting of the limit switch is automatically set back to an original limit setting.
