All other display conditions constitute either a warning or a fault condition. These conditions are explained in the section titled “Troubleshooting” (page 22) in the charts on Warnings and Faults.

Note 1: The level meter, which consists of the LEDs labeled 20% through 150%, will light according to the current amount of load connected. As the load exceeds one level, the next level will begin to blink, increasing the blink rate as the load increases until that full percentage is reached. For example, if the unit is loaded to 40% of maximum output power the 20% and 40% LEDs will be lit. If another small load is added increasing the load to 45% the 60% LED will begin to blink. If a little bit more load is added so that the total load becomes 50% the 60% LED will blink faster. This will continue until enough load is added to equal 60% of the maximum output power at which time the 60% LED will stop blinking and light continuously.

Note 2: The level meter described in note 1 above also displays the remaining battery time when the unit is in backup mode. If the batteries are fully charged when the unit switches to backup mode the 20% through 100% LEDs will light. As the batteries begin to discharge, the LEDs starting from the top will blink rapidly then slowly and will then turn off as the battery time runs down. For example if the unit has been running on battery power and there is 90% battery capacity remaining the 20% through 80% LEDs will be lit and the 100% LED will be blinking.
