2.3 PROTECTION SETTINGS
All 24 output contacts (Protection Settings 2001 to 2024) in the LPS-D are configurable. They can be driven by
any one of the functions as described by an index number provided in the Index Number Tables on pages 2–52
to 2–54. Each of the contacts has a default setting shown in Table 2–8: PROTECTION SETTINGS GUIDE on
page 2–61. The default settings are established through an Xpression Builder file that is downloaded to the
LPS-D in the factory. Any of the settings can be changed by modifying this logic via the Xpression Builder pro-
2
gram, by settings changes through the ALPS-Link program, or by settings changes with the keypad. Note that
any index number settings that are changed through the keypad or ALPS-Link will be reflected in the config-
urable logic file, while any settings that are changed through the configurable logic will be reflected in the set-
tings file.
2001: T1 - T1 Contact
2002: T2 - T2 contact
2003: T3 - T3 Contact
2004: T4 - T4 Contact
2005: T5 - T5 Contact
2006: T6 - T6 Contact
2007: A1 - A1 Contact
2008: A2 - A2 Contact
2009: A3 - A3 Contact
2010: A4 - A4 Contact
2011: A5 - A5 Contact
2012: A6 - A6 Contact
If other than the default setting is to be for any of these Protection settings, change the configurable logic or
select an index number reflecting the function by which the contact is to be driven.
2025: CONFTRIP - Initiate Three Pole Trip
The CONFTRIP setting allows tripping to be initiated through the trip output contacts that are used by the
scheme logic. CONFTRIP can be driven by any one of the functions as described by an index number provided
in the Table 2–7: INDEX NUMBERS – scheme, recloser, & programmable logic on page 2–54, or separate
logic can be designed using the Xpression Builder program.
2026: CONFOSC - Trigger Oscillography
The CONFOSC setting allows oscillography data capture to be initiated by the operation of selected signals
within the LPS-D logic, or via external input through a contact converter. Regardless of the setting of CON-
FOSC, oscillography data capture will always occur when the LPS-D issues a trip output. Care should be taken
to ensure that the signals chosen; if one of the selected triggers can operate frequently, trip oscillography data
may be overwritten and lost. CONFOSC can be driven by any one of the functions as described by an index
number provided in Table 2–7: INDEX NUMBERS – scheme, recloser, & programmable logic on page 2–54, or
separate logic can be designed using the Xpression Builder program.
