following. Remember to re-cycle the Key Switch if you make any changes to the chopper’s
configuration.
1) Select the Options required. See Chapter 5.4.
2) Select and set the Battery Voltage. See Chapter 5.4.
3) Confirm correct installation of all wires. Use the Console’s TESTER function to assist.
4) Perform the accelerator signal acquisition procedure using the Console “PROGRAM
VACC”. Procedure is detailed on Chapter 6.3.
5) Perform the steering potentiometer signal acquisition, using the parameters in "Adjust-
ment" menu (see Chapter 5.4).

6) Set the maximum steering angles, right and left direction; use the parameters in "Ad-
justment" menu (see Chapter 5.4).
7) Set the "MAXIMUM CURRENT” Current, using the table on Chapter 4.5 , 4.6.
8) Set the Acceleration Delay requirements for the machine. Test the parameter setting in
both directions.
9) Set the FREQUENCY CREEP level starting from level 0.6 Hz. The machine should just
move when the accelerator microswitch is closed. Increase the Level accordingly.
10) Set the Speed Reductions as required. Make adjustments to “CUTBACK SPEED”
Check the performance with the accelerator pedal totally depressed. If the machine is a
forklift, check the performance with and without load.

pedal. Adjust the level to your requirements. If the machine is a forklift, check the perfor-
mance with and without load.
12) INVERSION BRAKING. Operate the machine at 25% full speed. Whilst traveling IN-
VERT the Direction Switch. Set a soft Level of Inversion Braking. When satisfactory,
operate the machine at Full Speed and repeat. If the machine is a Forklift, repeat the
tests and make adjustments with and without load. The unladen full speed condition
should be the most representative condition.
