4.2.4 Aux ReLaY
The programmable Auxiliary Relays in the Digitrip 1150
consist of Relay A (Alarming), Relay B (Blocking), and
Relay C (Latching). If at least one relay function is en-
abled, an asterisk will appear beside the relay letter. The
selection of Relay A, B or C results in further selection of
two "groups" of settings. Relay A, when selected, gives
the option to enable or disable the pulse initiator and
enable kVAh or kWh settings. When PULSE INITIATE is
ENABLED, all groups for Relay A are skipped. When
DISABLED, Groups 1, 2 may be programmed and saved
for Relay A. Relays B and C do not have a PULSE
INITIATE option and are only programmable for Group 1.
(See Appendix D-15 and Appendix F)

4.2.5 ALARMS

Alarm programming functions the same way as other
options. Ten alarm settings exist. A listing of these options
and their settings can be found in Appendix D-16.
The selection of ALARM TO EventLOG setting will enable
both alarm events as well as trip events to be time-
stamped and placed in the three-position EventLOG.

4.2.6 ACCessory BUS (RELAYS)

Available addresses 1 through 4 each have four program-
mable relay functions (RLY FUNC) also numbered 1
through 4. When at least one function of an address is
enabled, an asterisk will appear beside the address
number. Options for each relay function include AUX,
ALRM, BELL, DEAD, WATCH and OFF. These options
may be saved for any combination of relay functions and
addresses. The Digitrip 1150 acts as the master to its
Accessrory Bus network and will light a green LED when
transmitting. See Figure 1.1 and also Appendix G.
Accessory Bus is not available on firmware version 8A.00.

4.2.7 TRIPLINK

Triplink is a means of transferring settings from one
breaker to another. Triplink transfers all protection set-
tings and breaker circuit data. The transfer of these
settings may be useful for cloning a lineup of breakers,
cloning a breaker's settings for replacing the breaker with
its clone for maintenance purposes, or for making com-
mon settings for a test program.
