Abstract

An apparatus and system for permitting dual-mode configuration of an appliance control board preferably in conjunction with an external electronic programming device or by means internal to the appliance. Preferably, a set of selection switches are provided in an interior space of the appliance that are used to select desired operating parameters. By changing the setting of the switches, the operator may configure the appliance for many specific modes of operation. In addition, the appliance can be electronically reconfigured by use of a hand held data probe.

Claims

1. A method of programming operating parameters for a machine'"'"'s mechanical subsystems, the machine having a user interface, comprising the steps of:

providing a programmable controller having a first input, a second input, a third input and an output;

the first input communicating with the user interface and the output communicating with the mechanical subsystems of the machine;

providing a first programmer communicating with the second input of the programmable controller, the first programmer capable of generating a first signal when it is activated;

providing a second programmer communicating with the third input of the programmable controller, the second programmer capable of generating a second signal when it is activated;

monitoring the second and third inputs of the programmable controller;

activating one of the first programmer and the second programmer;

detecting an input signal at one of the second and third inputs;

generating operating parameters in response to the detected signal at one of the second or third inputs;

storing the operating parameters in memory;

detecting a signal at the first input from the user interface;

determining whether the signal at the first input satisfies the operating parameters stored in memory;

generating a control signal if the signal at the first input satisfies the operating parameters stored in memory; and

sending the control signal to the output of the programmable controller to energize the mechanical subsystems of the machine.

2. A method according to claim 1 further comprising the step of ignoring a signal detected at the second input if a signal has been detected at the third input.

3. A method according to claim 1 wherein the third input is an optical transceiver.

4. A method according to claim 1 wherein the first programmer comprises a plurality of switches located on the machine.

5. A method according to claim 1 wherein the second programmer comprises a hand-held probe.

6. A method according to claim 1 further comprising the steps of changing the operating parameters stored in memory by activating one of the first and second programmer to generate one of a first and second signals.

7. A method according to claim 6 further including the step of ignoring the first signal if a second signal has been received.

8. A system for programming operating parameters of an appliance'"'"'s mechanical subsystems, the appliance having a user interface for receiving inputs from a user, comprising:

a second programmer generating operating parameter signals; and

a programmable controller having a first input, a second input, a third input and an output;

the first input communicating with the user interface, the second input communicating with the first programmer, the third input communicating with the second programmer and the output communicating with the mechanical subsystems,

wherein the programmable controller detects an input from one of the first and second programmers and stores the operating parameter signals, the programmable controller determining in response to an input from the user interface whether the input from the user interface satisfies the operating parameter signals programmed in the programmable controller; and

if so, generates an output signal to energize the mechanical subsystems.

9. A system according to claim 8 wherein the first programmer comprises a plurality of switches located on the appliance.
