2.3 PROTECTION SETTINGS
1840: DELTAVBLK - Block Synch Check by DELTAV
DELTAVBLK can be set to YES or NO and establishes whether the synchronism check function is allowed to operate. Set
DELTAVBLK = YES to block the synchronism check function, otherwise set DELTAVBLK = NO.
Up to eight of the signals listed in the Index Tables given at the end of this section can be used to produce a non-critical
2
alarm signal (Index Number 52). This signal, when produced, will always be reported as an event and it can also be pro-
grammed to drive one of the output relays if an external alarm is required.
1901: NCAIN1 - Non-Critical Alarm Input #1
1903: NCAIN3 - Non-Critical Alarm Input #3
1905: NCAIN5 - Non-Critical Alarm Input #5
1907: NCAIN7 - Non-Critical Alarm Input #7
Set these Protection Settings to one of the available Index numbers given in the Table 2–10: INDEX NUMBERS –
SCHEME, RECLOSER, & PROGRAMMABLE LOGIC on page 2–52.
All 24 output contacts (Protection Settings 2001 to 2024) are configurable. They can be driven by any one of the functions
as described by an index number provided in the Tables at the end of this section. Each of the contacts has a default setting
(see Table 2–11: PROTECTION SETTINGS GUIDE on page 2–57). The default settings are established through an Xpres-
sion Builder file that is downloaded in the ALPS at the factory. The settings can be changed by modifying the logic via
Xpression Builder, ALPS-Link, or through the keypad. Note that any index number settings changed through the keypad or
ALPS-Link will be reflected in the configurable logic file, while any settings changed through the configurable logic will be
reflected in the settings file.

Note: Settings 2005, 2006, and 2015 to 2018 are for Single Phase Tripping models only.
If other than the default setting is to be used, change the configurable logic or select an index number reflecting the function
by which the contact is to be driven.
The following contact output assignments are recommended when the phase identified channel scheme (HYBRIDP) is
used. Note that KT3 and KT4 only need to be assigned for the four channel scheme.
