Fault 44: 48 Volt Battery – Undervolt
InfoCenter Display:
Note:
All 48 V devices are connected to the same 48 V bus. If this is a system issue, the primary TEC will
combine all 4 component 48 V Bus Undervolt faults into 1 and fault 44 will report.
Fault Description
This fault is reported when all 4 individual 48 V bus circuit low voltage alerts are active at the same time.
Fault 44 is indicative of low battery power. Individual cutting unit or S/G failures report individually.
Circuit Description
All four 48 V devices are reporting a low voltage fault. The electric reel motors report this fault at 32V and the
S/G reports this fault at 36V. As a result, the bus voltage must be below 32V for the fault to occur.
