2-position connector serves to connect the VT-Probe to J2 on other VT-Probes in a daisy-chain
fashion described above.
Application
QS873 VT Probes can be used with or without mid-string voltage monitoring. Only one probe is
required to allow the battery slope thermal compensation function to be utilized. Additional
probes for individual battery or multiple string monitoring can be added as desired. The highest
temperature measured from all the probes is utilized by the controller. Although many systems
come with the probes factory installed, probes can be added or replaced in the field. The
following figure depicts monitoring all batteries in a single string without the use mid-string
voltage monitors. Actual cables and connectivity may depend on true system connect

Following are basic steps when installing the temperature probes for Thermal Compensation
without Voltage Monitoring.

Step
Action
1
The QS873A weatherized VT-Probe is provided with 2-pin and 3-pin receptacles and a
1/4-inch ring terminal. Insert the RJ-45 end of the 848719795 wire set into the P5-
SYS AUX PORT on the controller
2
Using voltage monitoring now or in the future?
No - Cut the brown voltage sense wire on the 848719795 at the 3-pin connector.
Yes - Insulate the end of the wire and secure it in the system for future use.
3
Insert the 3-pin connector end of the cable into the receptacle on the VT-Probe closest
to the controller.
