SUMMARY OF LED OPERATION

GSMVLP4G Status Display Operation

The GSMVLP4G Status Display has four LEDs used to indicate message and device status (refer to
Figure 5). When installed in the control, the LEDs appear in the following order from top to bottom.
STATUS, green
MESSAGE, yellow
FAULT, red
MINIMUM SIGNAL STRENGTH, green
Each LED can have four different states - ON, OFF, FAST BLINK and SLOW BLINK. Throughout this
document, the key shown in Figure 4 is used to describe LED state:

Minimum Signal Strength LED Operation

The Minimum Signal Strength LED normally displays the module's signal strength. The LED (green
LED) will be lit to indicate that the minimum required signal strength for installation exists between
the module and the receiving tower. Refer to Figure 9.
