Abstract
A method for automatically testing a relay is provided. The method includes applying power to a testing device for automatically testing the relay, determining a position of a selector switch based on a user selection for testing, selectively energizing the relay based on the position of the selector switch, detecting, by a hardware processor, an energize status signal from the selector switch, testing, by the hardware processor and based at least on the energize status signal, a control coil or a contact of the relay to generate a test result, and displaying, using display, the energize status signal and the test result.
Claims18
A method for automatically testing a relay, the method comprising:
- applying power to a testing device for automatically testing the relay;
- determining a position of a selector switch based on a user selection for testing;
- selectively energizing the relay based on the position of the selector switch, comprising:
- determining a position of an AC/DC switch based on a further user selection for energizing the relay, and
- applying a control voltage to the relay based on the position of the AC/DC switch;
- detecting, by a hardware processor, an energize status signal from the selector switch;
- testing, by the hardware processor and based at least on the energize status signal, a control coil or a contact of the relay to generate a test result;
- and
- displaying, using display, the energize status signal and the test result.
A testing device for testing a relay, comprising:
- an ON/OFF switch for applying power to the testing device for automatically testing the relay;
- an energize test selector switch for selectively energizing the relay based on a position of the energize test selector switch, wherein the position of the energize test selector switch is determined based on a user selection for testing;
- an AC/DC switch for selectively applying a control voltage to the relay based on a position of the AC/DC switch, wherein the position of the AC/DC switch is determined based on a further user selection for energizing the relay;
- a processor and a memory coupled to the processor, the memory storing instructions, when executed by the processor, comprising functionality for:
- detecting an energize status signal from the energize test selector switch;
- and
- testing, based at least on the energize status signal, a control coil or a contact of the relay to generate a test result;
- and
- a display for displaying the energize status signal and the test result.
A non-transitory computer readable medium (CRM) storing instructions executable by a computer processor for testing a relay, the instructions, when executed by the computer processor, comprising functionality for:
- applying power to a testing device for automatically testing the relay;
- determining a position of a selector switch based on a user selection for testing;
- selectively energizing the relay based on the position of the selector switch, comprising:
- determining a position of an AC/DC switch based on a further user selection for energizing the relay;
- and
- applying a control voltage to the relay based on the position of the AC/DC switch;
- detecting an energize status signal from the selector switch;
- testing, based at least on the energize status signal, a control coil or a contact of the relay to generate a test result;
- and
- displaying, using a display, the energize status signal and the test result.
A method for automatically testing a relay, the method comprising:
- applying power to a testing device for automatically testing the relay, wherein the relay comprises 11 pins;
- determining a position of a selector switch based on a user selection for testing;
- selectively energizing the relay based on the position of the selector switch;
- detecting, by a hardware processor, an energize status signal from the selector switch;
- testing, by the hardware processor and based at least on the energize status signal, a control coil or a contact of the relay to generate a test result;
- and
- displaying, using display, the energize status signal and the test result.
