Front Panel Warning/Alarm LED Messages <br />The Warning and Alarm LEDs on the front of the VSFC unit will blink when a fault is detected. The time between <br />blinks in an alarm or warning message is 0.5 second. If there is more than one warnings/alarm message, each <br />message is separated by a 2 second space. A single message or a multiple message sequence will continue to <br />repeat until the fault(s) is corrected and the Reset button on the front of the unit is pressed.
