2000 ECS-12U Controller J85501E-2
Issue 3 July 1998 Product Description 2 - 17
Power and Sense
Voltage Fusing
Figure 2-4 shows the fuse designations on the fuse board. The
fuse board has 18 fuses to distribute power and sense voltages:
F1-F12 provide battery sense voltage to the regulation leads
of the rectifiers.
F13 provides power and plant voltage sensing to the meter
circuits of the 113B and optional circuit pack CP2.
F14 provides power to the optional circuit packs CP2 and
CP3.
F15 provides power to the rectifier interface circuits on the
113B.
F16 provides power to the controller interface circuits on
the rectifiers.
F17 provides power to the ABS leads of the 113B.
F18 provides regulation battery (Reg Bat) power to the
circuitry on the 113B not powered by F13 or F15.
Major and Minor
Fuse Alarms
The fuse board provides Major and Minor Fuse Alarms to the
controller. A Major Fuse Alarm is generated when any of fuses
F16-F21 open, when a plant distribution circuit breaker trips
open for overcurrent (but not when manually turned off), or
when TB501-2 or TB501-4 is tied to the plant voltage. A Minor
Fuse Alarm is generated when any of fuses F1-F15 open or when
TB501-3 or TB501-5 is connected to plant voltage. TB501-1 is
also a Major Fuse Alarm equipped with a 1000 ohm dropping
resistor for distribution panels that are not so equipped.
Low Power
Distribution
The fuse board may provide low power distribution for customer
applications. Plant voltage is supplied to TB501, pins 6, 7, and 8
via fuses F19, F20, and F21 respectively. These three fuses come
factory equipped with 5-ampere ratings. Lower ampacity fuses
may be used to suit particular applications. Typical applications
include remote monitoring systems, alarm indicator panels,
temperature transducers, or any other equipment that requires
plant voltage at low ampacities. If any of these fuses opens, a
Major Fuse Alarm is generated.
