Thermal Compensation Connections - ABB CPS6000 Product Manual

Thermal Compensation Connections

Thermal Compensation
The optional QS837A VT-Probes are used to measure battery temperature for slope thermal
compensation, and to measure battery voltage for battery voltage imbalance detection when the
Voltage Monitoring Module 108958422 card is used. There is a maximum 18 probes.
Note: The number of probes per string is to be defined by the user. Typical installation requires 1
thermal probe per string of batteries.
Refer to Section 11 Peripheral Devices for more details about Voltage/Thermal Probes and the Remote
Voltage Monitoring Module if required.
Note: Do Not mount the VT-Probe under a lug or battery strap. The probe mounts on top of the - lug
or battery strap.
Note: Probes can be mounted prior to making the connections at the controller.
Step Action
1. Is the Voltage Monitoring option being used?
No - Locate the 848719795 Thermal Probe Cable.
Near the 3 Pin connector (Probe end), the volt
2.
sense wire has a 1 Pin connector on the end, cut
and discard this wire and insulate the trimmed
3. Connect the 3 Pin Connector into the 3 position plug on the VT-Probe.
Connect the other end of the Thermal Probe Cable to the controller P5- SYS AUX PORT connector. See
4.
Figure 5-8.
5. Are additional VT-Probes being used?
Yes - Using a interconnect cable connect the 2 pin
connector to the first thermal probe and then
connect the next probe with the 3 pin connector,
daisy chain until all probes are connected. See
6.
Figure 5-8.Two interconnect cables are available;
5 foot cable 848719803
10 foot cable 848719811
Attach probe case to each VT-Probe making sure the case pin inserts into the hole on the probe. Close
the case and verify the case is securely latched. See

Yes - Connect the 848652947 Battery Voltage
Monitor Cable between the ES771A Battery Voltage
Monitor Card and the controller P5- SYS AUX PORT
connector. See Figure 5-10.
No - Complete.
