Temperature Sensor Test - 2Nd Generation; 38V/76V With 3Rd Generation Bms - JLG X390AJ-X14J Supplement Manual

Temperature Sensor Test - 2nd Generation

1. Disconnect all temperature sensor connectors
(J1, J2, J3) from the BMS.
2. Check voltage between negative terminal and
sensor pin on connectors
a. If V=0: OK
≠
b. If V 0: Bad Insulation
3. Check sensor resistance values
10000 Ohm at 77°F (25°C)
15000 Ohm at 59°F (15°C)

38V/76V with 3rd Generation BMS

The 3rd Generation BMS can be arranged with one or
two electronic cards. The 38V and 76V BMS for 3rd gen-
eration are interchangeable with software update. The
3rd Generation BMS manages all the functions as
described in the 1st Generation BMS.
