Operation

3.2.7Alarm Limit Settings Screen

Go to the Master Menu and move the highlighted cursor to LIMIT SETTINGS. Press the Select pad and the Limit Settings screen is displayed.

The Alarm Limit Settings screen has Security Access to enable an authorized Liebert field-service engineer to adjust the UPS system alarm limit settings.

! CAUTION

All alarm limit settings are application matched and factory-set. They should not be changed casually. Contact Liebert Global Services for changing the alarm limit settings.

Overload Alarm (SCC and Modules): This alarm setting initiates an alarm message on the display screen warning the operator that the UPS system output current has exceeded the specified limit. This condition only activates an alarm. The UPS does not shut down, but a separate control circuit will transfer the critical load to bypass if the current and time of the overload condition exceeds sys- tem capability.

DC Overvoltage (Modules Only): This setting limits the maximum permitted level of the DC bus voltage. When this setting is exceeded, an alarm indication appears on the module display screen. The UPS module is taken off-line (the module output circuit breaker is tripped open) and the input and battery circuit breakers trip open.

Battery Discharging (Modules Only): When the battery voltage on the DC bus falls below this limit for 5 seconds, a Battery Discharging alarm message is displayed on the module screen. This means that the battery is discharging due to an input voltage sag or interruption or a module output overload.

Low Battery (Modules Only): While the battery is discharging, this alarm warns the operator that the Battery Shutdown level is approaching. This is generally set for a reserve time of approximately 5 minutes (typically 10 volts above the 60-Minute Battery Shutdown voltage), based on full load opera- tion.

Battery Shutdown (15 Minutes) (Modules Only): When the battery voltage decreases to this limit for five seconds during the first 15 minutes of the discharge, the battery circuit breaker opens to prevent overdischarge. Note that the rated battery reserve time at your site may be other than 15 minutes.

Battery Shutdown (60 Minutes) (Modules Only): During extended outages or deep sags of more than 15 minutes, the shutdown voltage limit will ramp up gradually to this 60-minute limit to prevent lengthy discharge and possible battery damage. The battery circuit breaker opens when the battery voltage and the shutdown limit are equal for five seconds. See the Battery Time screen for more infor- mation. Also refer to the battery manufacturer’s manual, available on the manufacturer’s Web site.

Battery Rating (100%) (Modules Only). This setting is the full load discharge rating of the battery in kilowatts for the rated backup period. A typical rating might be 500 kW for 15 minutes.
