•
After this wait time the display reading changes to “
B A C K
”. Now shift the travel lever backward
to start the surge current measurement in reverse.
•
During the measurement the actual current is displayed (display value = current in mA).
•
After completion of the measuring process in reverse the display will show
O K
again.
•
The travel lever must now be returned to braking position.
•
Once both surge currents have been learned correctly and the travel lever is in “braking position”,
the display shows the reading “
D O N E
”, the values are saved and the function is completed. Now
the machine can be operated again with the travel lever. The new surge current values for the travel
system are valid from the next start.
•
The teach function can at any time be aborted by operation of the emergency stop or the ignition
switch.
5.4.2 Procedure with software version 1.07 and 1.08
•
The speed selection switch must be in position ECO.
•
If necessary enter code number
9 9 9 9
to access the service mode.
•
Then enter
1 0 9 0
. This code number activates the function “Automatic detection of surge currents
in the travel system”; the display now shows the reading
0 0 0 0
with the first digit flashing. This
code number must be entered to be able to perform the following steps.
•
From this point the machine can no longer be operated with the travel lever! The travel lever
will only be in function again after the teach function has been completed or the machine
has been restarted.
•
Both measurements (forward/reverse) must be started by entering a code number. The code num-
bers for both travel directions are:
Determine surge current for control forward
1 0 9 1
Determine surge current for control reverse
1 0 9 2
•
After entering one of the above code numbers the measurement will only start after moving the
travel lever to the respective travel direction.
•
During the measurement the actual current is displayed (display value = current in mA).
•
Teaching is required for both travel directions.
•
When returning the travel lever to neutral position after the two measurements, the display will show
O K
for 3 seconds and the averaged values will be saved.
•
Once both surge currents have been measured the machine can be operated again with the travel
lever. The new surge current values for the travel system are valid from the next start.
•
The teach function can at any time be aborted by operation of the emergency stop or the ignition
switch.
The ASC fault indicator light will come on during the teach process. In this
case this is of no relevance. The warning will disappear when restarting
the machine.
