Magnetically-Mounted Temperature Sensors
The MMTS is connected to the CANbus connectors on the DIN rail. See Figure 5-4 for an
overview to the key parts of the product and Figure 5-30 below for a more detailed look
at the connection points.
CAN High (HI)
CAN 12 V
CAN Ground
CAN Low (LO)
CAN Shield
Due to the inability to reach the MMTS(s) once the transformer is energised,
communication with the sensor must be tested before the transformer is switched on (if
power to the product is available). Refer to the 'Measurement' section of the Intellix™
BMT 330 User Manual and check that the Field Sensors Error for Top Oil is not increasing
by 1 every second and that the respective temperatures in the Field Sensors are within
the expected range.
