Major Alarms are indications of a serious failure within the VMX Power Supply,
such as a loss of output voltage or a failed battery charger. Any situation that causes
the output to be off can be considered a Major Alarm. Any Major Alarm, when
encountered, requires immediate action to be taken by the operator to correct the
failure. To correct, simply, follow the Smart Display on-screen instructions.

Minor Alarms indicate a less serious failure, such as defective RTS or loss of utility
power. Corrective action can be delayed for a short time. To correct, simply, follow the
Smart Display on-screen instructions.

Two front panel LEDs indicate the condition and status of the VMX Power Supply.
The green Output LED, when illuminated, indicates the power supply is functioning
normally and supplying output AC to the load. A fl ashing output LED indicates that
a minor alarm has been detected. If the Output LED is off, a major alarm has been
detected.

The red Alarm LED either fl ashes or is off depending on the operating state of the
power supply. A fl ashing Alarm LED indicates that a major alarm has been detected.
This state clears when the alarm is no longer present. Normally, the red Alarm LED is
OFF indicating normal power supply operation.
