User Settings

The User Settings choice allows you to adjust the user-accessible switch settings. Access is limited to qualified personnel via system security.

To access the User Settings dialog box:

1.Select CONFIG.

2.Select USER SETTINGS from the pop-up menu.

The User Settings dialog box is displayed. See Figure 67. The top six buttons access a series of secondary dialog boxes to configure the various settings.

Source Setpoints

The Source 1/2 Setpoints allows you to configure trigger points for each input source (1 or 2) for the STS2/PDU via a keypad dialog or HI/LO dialog box. The source numbers do not designate the source as the preferred or alternate source. The numbers simply identify the input source. See 10.2 - Man- ual Transfer / Preferred Source Selection to set the preferred source.

The Setpoints are based on values in relation to the nominal voltage required for the STS2/PDU. UV refers to under voltage, meaning the amount of voltage below the nominal voltage. OV refers to over voltage or the amount of voltage over the nominal voltage.

•Fast UV Setting (%) — if the voltage drops below this set percentage of the nominal voltage, the STS2/PDU transfers from the current source to the opposite source.

•Slow UV Setting (%) — if the voltage remains this set percentage below the nominal voltage for the period of the slow detection delay, the STS2/PDU transfers from the current source to the opposite source.

•Slow UV detection delay — the number of cycles that the source must remain below the Slow UV Setting before the STS2/PDU transfers.

•OV Setting (%) — if the voltage exceeds this set percentage of the nominal voltage for the period of the OV detection delay, the STS2/PDU transfers from the current source to the opposite source.

•OV Detection Delay — the number of cycles that the source must remain above the OV Setting before the STS2/PDU transfers sources.

•I-PK Xfer Lockout — if current from the source exceeds this threshold, the STS2/PDU disables source transfers and has to be reset either manually or automatically. The type of reset is config- ured under the User Settings.
