4.
First, check out the traction system.
With the interlock switch closed, select
a direction and apply throttle. The motor should begin to turn in the
selected direction. If it does not, first verify the wiring to the forward and
reverse switches. If the wiring is correct, turn off the controller, discon-
nect the battery, and exchange the motor’s field connections (the
F1
and
F2
cables) on the controller. The motor should now turn in the proper
direction. The motor should turn proportionately faster with increasing
throttle. If not, refer to Section 7.
CAUTION:
The polarity of the
F1
and
F2
connections will affect the operation of emergency reverse. The
forward and reverse switches and the field connections must be configured
so that the vehicle drives away from the operator when the emergency
reverse button is pressed.
5.
If you are using a programmer, put it into the test mode. Observe the
status of the forward, reverse, and mode switches, and—if your applica-
tion has emergency reverse—the emergency reverse switch. Cycle each
switch in turn, observing the programmer. The programmer should
display the correct status for each switch.
If your application has a multiplexer, cycle these switches on the
multiplexer also.
6.
Take the vehicle down off the blocks and drive it in a clear area. It should
have smooth acceleration and good top speed. If not, see Section 5:
Vehicle Performance Adjustment.
7.
Test the braking of the vehicle.
8.
Verify that all options, such as high pedal disable (HPD), static return
to off (SRO), and anti-tiedown are as desired.
9.
On walkies, verify that emergency reverse is working correctly. If you
have the optional emergency reverse check wiring, verify the checking
circuit by momentarily disconnecting one of the emergency reverse
wires. The vehicle should coast to a stop and a fault should be indicated.
10.
Next, check out the hydraulic system.
If you are using a programmer, put
it into the test mode. Observe the status of the Lift and Lower switches.
Cycle each switch in turn, observing the programmer. The programmer
should display the correct status for each switch.
If your application has a multiplexer, cycle the Lift and Lower
switches on the multiplexer also.
11.
Drive the vehicle to a location that will provide enough room for the
hydraulic functions to be tested; if indoors, be sure the ceiling height is
adequate.
