READINGS

STOWED* (Stowed Star):
Lift is operating normally and the Controller (FIG. 72-1) is receiving the interlock signal
from the vehicle. The platform has folded, passed the stow switch, and is stowed. The
hydraulic system pressure is above 900 PSI and the Lift interlock signal is being sent to
the vehicle.
STOWED.* (Stowed Dot Star): Lift is operating normally and the Controller (FIG. 72-1)
is receiving the interlock signal from the vehicle. The platform has folded, passed the stow
switch,and is stowed. The hydraulic system pressure is below 900 PSI. When the Con-
troller recharges hydraulic system pressure every 5 minutes, the dot (.) will go away and
Controller (FIG. 72-1) will read STOWED*.
STOWED (Stowed): Lift is operating normally and the Controller (FIG. 72-1) is receiving
the interlock signal from the vehicle, but the Lift interlock signal is not reaching the vehicle
interlock. The platform has folded, passed the stow switch, and is stowed. The hydraulic
system pressure is above 900 PSI. If vehicle interlock uses the absence of the Lift in-
terlock signal to prevent vehicle from being moved when lift is not properly stowed, then
vehicle will not be allowed to move until it receives interlock signal from the Lift.
Corrective Actions:
1. Make sure the Stow switch is adjusted correctly.
If required, do the STOW SWITCH ADJUSTMENT in this manual. When the plat-
form is resting on the latches, the STOW switch must be closed.
2. If the adjustment does not solve the problem, then check the wire that sends Lift
interlock signal to the vehicle interlock (see ELECTRICAL SYSTEM DIAGRAM).
The Controller (FIG. 72-1) may display any of the following readings while the Lift is
operating. Some of the readings indicate normal operation, but some indicate trouble with
the Lift or vehicle.
