TM
S46A/B
B– to the optional End-of-Aisle Sensor (S47B) at S47B-8. It is then routed through the switch module to S46B-7 to S46A-8. It is connected on the TM through Fuse FU13 to JPS14-3 and 4, and on to TP4. There is no harness wiring connected at this point.
TM
S47A/B
B– for the Main Lift Pressure transducer.
Measure B+ at TP1 to verify connections. B– for the Load Handler Motor Temp Sensor. Then check for <0.5V wrt TP4.

SENSOR 2
Input voltage to the TM. It is generated by either S47A or S47B when one or both of them detect the presence of a floor magnet. SENSOR 2 is used along with SENSOR 1 (JPT12-10) to determine if the truck is in or out of the aisle. This information is used to control travel speed based on truck location and the position of the AUTO/MAN switch.
Magnet not sensed: >4V Magnet sensed: <1V

JPT24-18
MAIN LIFT PRESS.
Analog DC voltage that varies directly with the weight on the carriage. Approx. 1V per 1000 lb. (453 kg). It is necessary to have the TM supply approx. 12V as well as DGND in order for the transducer to function correctly.
Forks Fully Lowered: 1V

JPT24-19
MINI LIFT PRESS.
Analog DC voltage that varies directly with the weight on the mini-mast. Approx. 1V per 1000 lb. (453 kg). It is necessary to have the TM supply approx. 12V as well as DGND in order for the transducer to function correctly.

JPT24-20
BATTERY GATE RT
Input voltage to the TM from the optional Battery Gate Prox 2 (S58). The proximity switch is used to detect the right battery gate is correctly installed. Travel is inhibited when the switch does not detect a correctly installed gate.
Gate installed: <1V Not installed: >4V
