2.1 FACEPLATE
2.1.1 Light Emitting Diodes (LED)
The lights on the module faceplate are green, yellow, and red. They indicate on-line, off-line, and
fault states respectively. When the module circuitry detects an on-board fault, the red LED (fault)
is lit.
2.1.2 Mode Switch
The Mode Switch supports three positions: Enabl, Diag and Disab. The Mode switch must be in
the Enabl position for the UMI to function properly.
2.1.3 Reset Button
When the Reset button is pressed, the module buffers and registers are cleared, and the module
application program is restarted. The module is taken out of service, and all connections are
terminated.
