2.C Individual changes to the micro - speed control for A or B ports.
For certain valves the micro-speed can be less well defined, due to non-symmetry in the valve,
hydraulic system or in the crane / machine. If this is the case, the final speed of the micro-
speed can be changed and adjusted (i.e. for max. lever position) for A or B port for all
movements.
Note.: After the completed adjustment of the micro-speed :
The remaining micro-speed's "reduction steps" will be proportional to the setting.
Example:
After installation and test running it is found that the 3rd and 5th lever/movement
final speed, with micro-speed, needs to be increased or decreased for A or B ports.
DO AS FOLLOWS !
1. Remove the battery pack. Connect the cable between the control unit and electronicbox and
test run the crane's movements. Then press the emergency stop on the control unit and
emergency stop on the crane.
2. Twist up the emergency stop on the control unit and on the crane.
3. Press the control unit's ON/SIGNAL/FREQ.-SHIFT button.
(The red LED should light continuously).
4. Produce impulses in very quick succession with spring return switch MICRO to RIGHT in
the OFF direction until the control unit gives a long beep signal. Wait approx. 12 seconds
until the next long beep signal then continue with item 5.
Note 1. The red LED will be extinguished each time the control unit gives a beep signal.
Note. 2. If you do not receive the first long beep signal, start again from item 1 and execute items 3. and 4.
quicker. Items 3. and 4. must be executed within max. 5 seconds.
5. Now press ON/SIGNAL/FREQ.-SHIFT four (4) times.
( The control unit's built-in beeper will give four short beeps once every 5 seconds to confirm that the items
above have been done correctly. If any other beep signals are heard you must restart from item 1 again ).
Now you can easily change the micro final speeds for A or B ports, see item 6.
6. Now you can operate the crane. Move the 3rd manoeuvre lever just enough to start the
crane moving in for example the A direction. Give switch MICRO impulses to the LEFT in
the ON direction if the micro-speed is to be increased. Give switch MICRO impulses to the
RIGHT in the OFF direction if the micro-speed is to be reduced. Do the same for the B
direction.
Move the 5th manoeuvre lever to its maximum in for example the A direction. Give switch
MICRO impulses to the LEFT in the ON direction if the micro-speed is to be increased.
Give switch MICRO impulses to the RIGHT in the OFF direction if the micro-speed is to
be reduced. Do the same for the B direction.
7. Press the emergency stop on the CONTROL UNIT.
Programming is now completed and the crane is operating with the speeds YOU decided in
item 6.
If you are not satisfied with any start speeds repeat these as above. See item 1.
