module has four form C relay contacts numbered 1 through
4. Programmable relay functions (RLY FUNC) for each
relay include AUX, ALRM, BELL, DEAD, WATCH, LDT,
SDT, INST, GND,HLAlm,GFAlm and OFF.
(See Appendix F
for definitions of these settings.)
These options may be
saved for any combination of relay functions and ad-
dresses. The Digitrip 1150 acts as a master to its Acces-
sory Bus network and will light a green LED located in the
upper right corner of the trip unit when transmitting
(See
Figure 1.1 and also Appendix H).
The AUX function can be used as a circuit breaker auxiliary
switch in application. BELL will initiate on any “protection”
trip and can be used as a circuit breaker bell alarm trip
function. The INST function will drive the Accessory Relay
when an instantaneous trip is encountered. Similarly LDT
function will drive the relay on a circuit breaker Long Time
trip and SDT for a Short Time trip. The GFT (Ground Fault)
will operate the Accessory Relay on a ground trip. High
Load alarm will activate with the HLAlm setting. GFAlm is
for a Ground Fault Alarm function. ALRM (alarm) will drive
the Digital Relay in the same way as the assignments of
Relay A. The one exception is the Accessory Bus relay
will not function as a Pulse Initiator. The WATCH (watch-
dog) function, when programmed, can provide a status
monitor of the Digitrip 1150 energizing the programmed
relay and will drop out if an abnormal condition exists
within the Digitrip or if auxiliary power is low voltage. The
DEAD (deadman) function, when programmed, will pick up
the relay if the Module is communicating properly with the
Digitrip 1150. It will drop out if the Module is not communi-
cating properly. This function should be assigned to the
last physical Module in a wiring lineup to verify the
integrity of the wiring.
Accessory Bus is not available on PROTECT firmware
version 8A.00. The settings of INST, SDT, LDT, GNDT
GFAlm and HLAlm will require PROTECT firmware version
8A.05 or higher. Settings OV/UV, OF/UF, RevPwr will
require versions PROTECT 8A.09 and DISPLAY 8B.09 or
greater.

Ground shielding at computer BIM as shown. Where devices
are daisy-chained, interconnect shielding, but do not ground the connection.
100 ohm ½ watt carbon resistor required at last breaker. See T.D. 17-513.
Also insert 100 ohm resistor to terminator at CONI card (via switch on CONI).
See Appendix D-11 for programming INCOM function.
AEM is compatible with Digitrip 1150 with AEM firmware version 7.1and the
Digitrip 1150 set in the DT 910 COMM mode. (See page D-11)
Breaker Interface Module (BIM ) Version 3.12 is compatible with Digitrip 1150
Cat # 1 ****. BIM version 3.20 or greater is compatible with Digitrip 1150
Cat # 1 **** and Cat # 11 ****.
