Sensor plugged in: approx. 8V Sensor unplugged: 10 to 13V
TM
S47A/B
This is a custom input to the TM. Used for special optional inputs. When this is used, the ability to disable lift and reduce travel speed is possible.
Open: >4V Closed: <1V

SENSOR 1
Input voltage to the TM from aisle detect sensor S46A. It is generated by either S46A or B when one or both sensors detect a floor magnet. Sensor 1 is used along with Sensor 2 (JPT24-17) 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 position of the AUTO/MAN switch.
Magnet not sensed: >4V Magnet sensed: <1V

B–F
This connects B–F on the TM to TP4 (B–) through FU6 on the Fuse/Relay Card. These B– provide the return for everything not using DGND or AGND as reference.

+12V_SENSOR 2
12V to the optional End-of-Aisle Sensor (S47A) at S47A-3. It is then routed through the switch module to S47A-4 to S47B-3 to power that switch module also. There is also a circuit detect to verify the end-of-aisle sensor is connected. This voltage is present when the Key switch (S1) is ON.

DGND
This connects DGND on the TM to TP4 (B–) through FU6 on the Fuse/Relay Card. This is the reference for all circuits on the truck that reference DGND.

DGND
B– for the Brake Deadman switch (S2). It is also used as a shield to the BUS communications.
