BATTERY THERMAL RUNAWAY SYSTEM OPTION SECTION
System Schematic:
Figure 1 shows a schematic of the power supply and temperature sensor
PCB and the connections. The schematic shows a two temperature sensor
board system with four temperature probes connected to each monitoring board
but there are many other different possible configurations. Dry contacts are setup
for normally open configuration. Contact rating: 0.5 Amps @ 277VAC maximum.

Description of Operation
The Thermal Runaway System monitors each of the battery temperatures
individually and annunciates an alarm if one of two conditions occurs.
1) If any of the connected battery temperature probes measure a
differential rise greater than 40°C between the measured battery
temperature and the ambient temperature as measured from a
temperature sensor on the Temperature Sensor PCB.***
***Note: The Temperature Sensor PCB Modules must be mounted in
proximity to the batteries that are being measured. Never lengthen or
splice the supplied battery temperature probes to move the Temperature
Sensor PCB further from the measured batteries.
2) If any of the connected battery temperature probes measure an
absolute temperature greater than 80°C.
