Step Action
1 Insert one RJ-45 end of the 848652947 wire set into the P5-SYS AUX PORT on the
controller and the other end to the first ES771A Remote Voltage Monitor module.
2 Follow the steps for installing a probe described in the previous section to attach a VT
probe to the negative post located at the center of the string as depicted in Figure 7.4.
Do not cut the brown wire.
3 Dress and attach the snap fit connector on the brown wire to the appropriate snap fit
pin on the ES771A (J1-J3).
Note: exercise care when attaching the battery voltage sense wire onto the J1, J2, and
J3 pins of the ES771A pins. These push-on clips can be deformed if excessive force at
an incorrect angle of insertion resulting in a non-optimum connection. The contact
should not be bent more than 10 degrees.
4 Verify that the controller automatically registers the number of ES771A modules (1) at
the front panel location: MenuStatusBatteriesNum Mid-String V
Note: Modules will only be recognized when there is actual potential applied through
the VT probe to the ES771 module.
5 Connect another ES771A to the controller by connecting an additional 848652947 wire
set from the first module to the RJ45 receptacle on the second module.
Verify the number of modules (2) registered with the controller with command:
MenuStatusBatteriesNum Mid-String V
6 Repeat Step 5 until all modules are installed. Verify that all probes are also
automatically detected by the controller at the front panel at:
MenuStatusBatteriesNum Temp Probes
7 If the LEDs on the module(s) are not illuminated green on or are red or if the number
of registered modules does not agree with the number used: Check integrity of all cable
connections
8 Issue the Clear Events command: MenuControl/OperationsClear Events. If the
LEDs are still not lit green or if the number of registered modules still does not agree,
call your local field representative.
The system is now set to monitor both voltage and temperatures to support the batter string
voltage imbalance and slope thermal compensation features. Figure 6-5 depicts a reserve system
where every battery in the string being monitored for temperature. Again, the highest temperature
measured will be used for battery thermal management. Only one temperature probe is required
for thermal compensation features.
