e-Fan Cooling System Controllers
with J1939 Interface
Module Connection Descriptions
Sensor #1 Input (emc-1P & emc-1V)
This input is designed to allow non SAE J1939 connected zones to be measured if required. The input
accepts a standard NTC thermistor. This input should be referenced to the Signal Ground (0V) on the
connector. The GUI is used to select / de-select and set-up the signal from this additional input and how it
effects the fan speed control. Note: Use Pin 8 for signal ground as the reference for temperature sensor
#1.
Sensor #2 Input (emc-1V only)
This input is designed to allow non SAE J1939 connected zones to be measured if required. The input
accepts a standard NTC thermistor. This input should be referenced to the Signal Ground (0V) on the
connector. The GUI is used to select / de-select and set-up the signal from this additional input and how it
effects the fan speed control. Note: Use Pin 9 for signal ground as the reference for temperature sensor
#2.
SAE J1939 High
This is the High side of the J1939 CAN Bus communication port. The cable used should be suitable for
this type of data connection. Reference, SAE J1939/01 3.1.8, J1939/11 and J1939/31, Please observe
proper Bus protocol including correct termination.
NOTE: The emc1P & emc-1V DO NOT have terminating resistors fitted – these must be system
supplied by others.
SAE J1939 Low
This is the Low side of the J1939 CAN Bus communication port. The cable used should be suitable for
this type of data connection. Reference, SAE J1939/01 3.1.8, J1939/11 and J1939/31, Please observe
proper Bus protocol including correct termination.
NOTE: The emc1P & emc-1V DO NOT have terminating resistors fitted – these must be system
supplied by others.
Power Supply Input
This terminal is the Main +Supply Voltage input on the controller. To provide the best possible noise
resistance and current capability, this input should be taken directly to battery Positive or the power
supply +V output using a large current capacity cable. An ACG 5, ATO 5 or compatible fuse should be
installed as close as practical to the originating power source.
Range – 9 to +32VDC
Note: Failure to install a proper fuse in-line with the controller will void the
warranty.
