Liebert 1000kVA manual Modem Baud Rate, Maximum Auto-Retransfer Attempts

Operation

Modem Baud Rate

This sets the transmission rate at which the system relays data to a terminal through the modem.

To change the modem baud rate, do the following at the SCC:

1.From the System Configuration screen, press the Up or Down pad to move the highlighted cursor to Auto Dial.

2.Move to and select the Modem Baud Rate.

3.Press the Up or Down pad to display the desired baud rate.

4.Press the Select pad to set the baud rate and to return to the System Configuration screen.

Maximum Auto-Retransfer Attempts

When a UPS output overload condition exceeds a pre-programmed current-versus-time window (based on the SCC current rating), the UPS automatically transfers the critical load to the bypass line. After the overload condition has been corrected, the UPS attempts to automatically retransfer the critical load to the UPS output (unless zero attempts is selected). The Maximum Auto-Retrans- fer Attempts limits the number of times (0 to 5) that the UPS attempts to retransfer the load back to the UPS within a one-hour time period.

If more than the selected number of overloads occurs during one hour, the critical load remains on the bypass line and must be manually retransferred to the UPS system. Note that you should determine the cause of any overload condition.

Note that automatic retransfers are initiated only if the critical load was transferred to the bypass line because of a system overload. If an automatic transfer to bypass occurred for any other reason, an automatic retransfer will not be initiated. Refer to 3.5.3 - Automatic Retransfers to UPS.
