Voltage/Thermal Probes
The QS873A Voltage/Thermal Probes (VT-Probes) are used to measure battery temperatures
for slope thermal compensation, and to measure battery voltage for battery voltage imbalance
detection. They convert temperature measurements into serial data and transmit them to the
system controller using the 1-Wire® bus from Maxim. They can also send battery voltage
measurements to the system controller when used with the ES771A Remote Voltage Monitor.
All probes are provided with a ptc device to protect against accidental short circuit during
voltage measurements. Note: The CPS6000 system cannot use the thermal probes that are
used with other Lineage Power systems, e.g., CPS4000. The QS873A VT-Probes have a case
that is used for weatherproof installs.

J2
This 3-position connector serves to connect the VT-Probe to the Distribution Module using
the H569-470GB (848719715) cable. It may also be connected to the ES771A Remote
Voltage Monitor Module or be connected to other VT-Probes in daisy chaining using either
the H569-470GC (848719803, 5-ft) or the H569-470GD (848719811, 10-ft) cable.
This connector also serves to connect the VT-Probes to the ES771A in making voltage
measurements by using the H569-470GF (848719829) cable. This cable terminates on one
end in a right-angled snap-fit connector and on the other end with a connector pin-socket. The
pin-socked end of the cable is to be inserted into either of the two unused pin housings of the
connector. See Installation Instructions for more details.

This 2-position connector serves to connect the VT-Probe to J2 on other VT-Probes in daisy-
chaining them together.
