Abstract

A system for commissioning a controller accepts a different manual input during each of several different phases of the installation and provides the installer with a different detectable cue during each phase. The installer provides the manual input and then operates a switch indicating the input is present. The system stores the manual input present and advances the system to the next phase, and in a preferred embodiment provides a visible cue identifying each phase. The preferred embodiment uses devices controlled by the controller during normal operation and which also have manual position adjustment or set point selection to provide the manual inputs.

Claims

1. A data entry system for accepting manually generated data values, said system comprising:

a) first and second data entry elements respectively providing first and second data entry signals responsive to a manual input applied to the respective data entry element, said second data entry signal encoding a plurality of data values dependent on the manual input;

b) a phase index memory element recording an alterable phase index value;

c) an indicator element receiving the value recorded in the phase index memory element and providing a different, humanly discernable signal pattern indicative of the phase index value;

d) a phase index control element in operating relation to the phase index memory element and altering the phase index value responsive to each first data entry signal; and

e) a data memory receiving the second data entry signals, said data memory having at least first and second memory locations each for storing a data value, and each memory location associated with one of the phase index values, said data memory recording the data value encoded in the second data entry signal in the memory location associated with the current value of the phase index.

2. The system of claim 1, wherein the second data entry element comprises a control element having an output element having a plurality of positions and a position sensor providing a position signal encoding the output element position, wherein the manual input comprises an element for manually positioning the output element.

3. The system of claim 2 wherein the control element comprises a mechanical actuator having an output shaft forming the output element and changing position responsive to positioning power, a shaft position sensor comprising the position sensor, and a manually operated switching element providing positioning power to change output shaft position responsive to operation of the switching element.

4. The system of claim 3, further including an element for testing the phase index value, and responsive to a preselected phase index value, entering an operating control functions mode receiving the data values stored in the first and second memory locations.

5. The system of claim 4, wherein the phase index control element alters the value recorded in the phase index memory element by a first preselected value responsive to the first data entry signals.

6. The system of claim 5, including a third data entry element providing a third data entry signal, wherein the phase index control element alters the value recorded in the phase index memory element by a second preselected value different from the first preselected value responsive to each of the third data entry signals.

7. The system of claim 4, wherein the indicator element comprises

a) a first light source providing visible light responsive to a source voltage;

and

b) a blinking control receiving the phase index value, said blinking control providing to the light source, a number of pulses of source voltage equal to the phase index value.

8. The system of claim 4, including

a) a condition sensor providing a condition signal, said condition sensor in operative relation to a physical parameter controlled by the output shaft, and encoding in the condition signal a value dependent on the physical parameter;

b) a set point error generator for selecting a set point value for the physical parameter, said set point error generator receiving the condition signal and providing an error signal encoding a value dependent on the difference between the set point value and the value encoded in the condition signal; and

c) a data recorder receiving the phase index signal and responsive to a preselected value thereof, recording the value encoded in the error signal in a memory location associated with the phase index value.

9. The system of claim 2, including a

a) a condition sensor providing a condition signal, said condition sensor in operative relation to a physical parameter controlled by the control element, and encoding in the condition signal a value dependent on the physical parameter;

b) a set point error generator for selecting a set point value for the physical parameter, said set point error generator receiving the condition signal and providing an error signal encoding a value dependent on the difference between the set point value and the value encoded in the condition signal; and

c) a data recorder receiving the phase index signal and responsive to a preselected value thereof, recording the value encoded in the error signal in a memory location associated with the phase index value.

10. The system of claim 1, wherein the indicator element comprises

a) a first light source providing visible light responsive to a source voltage;

and

b) a blinking control receiving the phase index value, said blinking control providing to the light source, a number of pulses of source voltage equal to the phase index value.

11. The system of claim 10, including

a) a second light source providing visible light responsive to a source voltage;

and

b) a data test element receiving the phase index value and the second data entry signal, and providing a preselected pattern of source voltage pulses to the second light source responsive to a comparison of the value encoded in the second data entry signal with a prerecorded value dependent on the phase index value.

13. The method of claim 12 further including the step of altering the value recorded in the phase index memory element by a first preselected value responsive to each of the first data entry signals.

14. The method of claim 13 further including the step of altering the value recorded in the phase index memory element by a second preselected value different from the first preselected value responsive to a third data entry signal.

15. The method of claim 14 wherein the step of providing a signal to an indicator element further includes the step of providing to a light source, a number of voltage pulses equal to the phase index value.

16. The method of claim 12 further comprising the steps of:

a) providing a condition signal having a value specifying the state of a controlled parameter;

b) providing a manually adjustable set point signal specifying a particular condition signal value;

c) providing an error signal dependent on the values encoded in the set point signal and the condition signal; and

d) adjusting the set point signal to an extreme value of the condition signal; and

e) responsive to a preselected phase index value, recording the error signal in association with the preselected phase index value.

12. A method for operating a data entry system for accepting manually generated data values, said method including the steps of:

a) providing first and second data entry signals responsive to a manual input applied to the respective data entry element, said second data entry signal encoding a plurality of data values dependent on the manual input;

b) recording an alterable phase index value;

c) receiving the value recorded in the phase index memory element and providing a different, humanly discernable signal pattern indicative of the phase index value to an indicator element;

d) altering the phase index value responsive to a first data entry signal; and

e) recording in a data memory location associated with the current value of the phase index, the data value encoded in the second data entry signal.
