This section explains the front panel indicators and startup
procedures for the IMDSI13, IMDSI14, and IMDSI22 Digital
Input Modules.
The DSI modules have point (input) status LED indicators on
the front panel to aid in system test and diagnosis. There are
16 LEDs divided into two groups of eight (group A and group
B). The location of the LEDs is shown in Figure 4-1. Each indi-
cator represents a digital input. A red LED indicates an ener-
gized input. A blank LED indicates a nonenergized input.
