Theory of Operation
Normal Level
12VP
Supplies working voltage to the 120/150 in. switch (S29). If not present, check voltage at STM JPT9-6 and see if IL1 is lit.
Key switch closed = +10.8 to13VDC
STM
120/150 inch switch
JPT5-1
HEIGHT 120/150 in. SW (S29)
Supplies B– to circuitry on the STM when the switch is closed. When the switch is open, the lift truck has limited travel speed.
Switch closed = 1VDC Switch open = 5VDC
120/150 in. switch

JPT5-3
DGND
B– for S29, supplied through the STM via B– cable at the TPA.
0.5VDC wrt TP4 (B–)
STM
S29
118
JPT5-5
12VP
Supplies working voltage to the180 in. switch (S25). If not present, check voltage at STM JPT9-6 and see if IL1 is lit.
Key switch closed = +10.8 to 13VDC
STM
180 in. switch
119
JPT5-4
HEIGHT 180 in. SW (S25)
Supplies B– to circuitry on the STM when Switch closed = the switch is closed. When the switch is 1VDC open the lift truck has limited travel speed. Switch open = 5VDC
180 in. switch

JPT5-6
DGND
B– for S25, supplied through the STM via B– cable at the TPA.
0.5VDC wrt TP4 (B–)
STM
S25
121
JPT5-8
12VP
Supplies working voltage to the Lift-Limit Switch (S24). If not present, check voltage at STM JPT9-6 and see if IL1 is lit.
Key switch closed = +10.8 to13VDC
STM
S24
122
JPT5-16
LIFT LIMIT SW (S24)
Supplies B– to circuitry on the STM when the switch is closed. When the switch is open the lift truck has no lift unless the bypass switch (S51) is closed.
Switch closed = 1VDC Switch open = 5VDC
LIFT LIMIT SW
STM
123
JPT5-7
DGND
B– for S24, supplied through the STM via B– cable at the TPA.
0.5VDC wrt TP4 (B–)
STM
S24
124
JPT7-2
12VP
Supplies working voltage to the optional switch. If not present, check voltage at STM JPT9-6 and see if IL1 is lit.
Key switch closed = +10.8 to13VDC
STM
Optional Switch
125
JPT7-1
SPARE IN 3
Supplies B– to circuitry on the STM when the switch is closed. When the switch is open, the lift truck disables the appropriate function.
Switch closed = 1VDC Switch open = 5VDC
Optional Switch
STM
126
JPT7-3
DGND
B– for the optional switch, supplied through the STM via B– cable at the TPA.
0.5VDC wrt TP4 (B–)
STM
Optional Switch
127
JPT5-15
NC
Not connected to any circuitry on the STM.
NA
128
JPT10-2
B+F
Supplies B+ to the key switch on the carriage via the over-the-mast cable. B+ is supplied from FU2 on the STM.
Battery plugged in = B+ battery disconnected = 0V
