Diagnostic Tests

Upon power-up, the TigerSwitch 100 units perform self- diagnostic tests (See Chapter 3). Diagnostic tests similar to those performed on power-up can be run using the Configure button:

1.Use a long press (>2 seconds) to begin function selection. The Status LED will start to flash to indicate that functions may be selected. Use short presses (<2 seconds) to cycle through the status LEDs until the Diagnostic LED lights. Use a long press to initiate diagnostic tests.

System Diagnostic Tests

The diagnostic test sequence is performed in two stages. The first stage is the system diagnostic test. The following table details system level failures, which are indicated in the Select/Link row of the LED array:

	System Failures
