Battery Reserve
Time Prediction
(J85501F1 L-K1)
This optional feature requires no additional circuit packs, but does
require that a temperature probe be added to provide Galaxy with the
temperature of one of the plant battery strings. Once this probe is in
place and wired, the feature is enabled through software.
Included with the Battery Reserve Time Prediction option are the
following:
• Thermistor Assembly for mounting on a TR (Temperature
Reference) cell of the battery.
• An 85-foot cable assembly and plug for mounting at Galaxy
BJF board.
1. Connect the cable assembly and plug into the Temp Probe
Connector jack of the Galaxy BJF board, routing it from the rear to
the front of the Galaxy through the holes on the right side. See
Figure 3-2.
2. Run and secure the assembly wiring from the Galaxy to the chosen
Temperature Reference cell of a plant battery string. Terminate the
thermistor assembly in a vacant hole of a battery post (KS20472
Round Cell) or wire tie the assembly close to a post or battery case
for other styles of batteries. Protect against the possibility of
shorting out a battery cell during this procedure.
Wiring Options
Rectifier
Sequencing
Internal Rectifier Sequencing is a feature of the Intelligent Control
board, but requires external wiring to ETR/ETRR (BJT TB3-12/13) and
RO/ROR (BJT TB3-14/15) in order to function. This wiring is explained
below and shown in Figure 3-15.
