Installing Optional Sensors/Transducers
12.1.
String Current Transducer
The system can be used with current transducers to measure high string currents such as charge and
discharge currents. When installing this option a specific harness will be included in the installation kit.
One of two standard lengths will be supplied. The 1102-189-12 is a12’ cable and is typically used in
battery cabinet installations and the other is a 50’ cable, 1102-189-50 used for large cell count flooded
type battery installations.
The Transducer itself is a split core design and requires to be installed across one of the battery cables
that will be carrying all of the current going into or out of the battery. There are two dots on the casing
that indicate the direction it needs to be installed. These two dots must always point closest to the
negative end of the battery.
Note
: If the sensor is not installed with the two dots pointing towards the negative end of the
battery, discharge events will not be captured
.
Figure 32 - String Current Transducer Connections
When using a current transducer, connect the 4–conductor shielded cable to the current transducer as
shown in the above figure. Connect the opposite end to the string current connection on UXSM or
UXCM depending on which components are being used. See figure below for an illustration of the
connector arrangement.
