AUTO RESET TIMING

5

The source qualification timer dictates how long to allow for input and bypass voltages to return to their nominal limits. The default value is 100 with a programmable range of 5-100 minutes. Since a setting of 100 signifies an infinite wait time, the finite range can be set between 5 and 99 minutes.

Normally, 5 minutes is adequate.

Setting the Auto Restart to SYSTEM, automatically changes the setting for Motorized Battery Breaker to “Motorized”. The battery type setting cannot be changed back to Manual once Auto Restart is set to YES. However, if Auto Restart Option is Disabled (Set to NO), battery type can be independently set to Motorized. To access the proper screen, navigate to Configuration, then System Settings, then Options, then Motorized Battery Breaker, and select Motorized.

Once in Auto Restart mode, a new screen will report the progress. (See Figure 104).

AUTO RESTART IN PROGRESS

QUALIFYING INPUT POWER

CANCEL

The message, AUTO RESTART IN PROGRESS will be displayed during the Auto Restart sequence. The text line below this message signifies the condition being checked, and flashes in reverse video while the message is displayed.

The Operator can cancel the Auto Restart operation by selecting and acknowledging CANCEL. When this is done, a message will appear asking, “Canceling will abort Auto Restart operation. Are you sure you want to cancel? The Operator can then select YES or NO”.

Alarm Notifications

At the start of Auto Restart operations, an alarm condition is recorded to log “Auto Restart Initiated”. If during the process Auto Restart is halted as a result of failed condition, a subsequent alarm is recorded as “Auto Restart Failed”. This will be a latched alarm and must be acknowledged and reset by the Operator. See Alarm Messages on page 74 for a complete description of these alarms.

Auto Restart Trigger Condition

Any time the UPS detects and records an EOD (End of Discharge) condition occurring at the same time the input contactor is open, it recognizes that the batteries can no longer support the load. This scenario sets the Auto Restart flag, initiating the Auto Restart sequence.

In a Dual Input system, both Input and Bypass must be available to enable Auto Restart.
