MECHANICAL END-STOP ADJUSTMENT
The mechanical end-stops can be adjusted by acting on the two grub screws accessible through the holes 1 and 2
(26) in the support plate of the control unit container.
To access the two long adjustment grub screws, completely unscrew the two short grub screws that lock the long
grub screws.
Referring to figure 26, the grub screw 1 acts as closing mechanical end-stop, while the grub screw 2 as opening
mechanical end-stop.
Tightening the grub screw 1 you anticipate the moment it will meet the mechanical end-stop of the operator during
closing stopping its motion (the boom will close less).
Loosening the grub screw 1 you delay the moment it will meet the mechanical end-stop of the operator during
closing stopping its motion (the boom will close more).
Tightening the grub screw 2 you anticipate the moment it will meet the mechanical end-stop of the operator during
opening stopping its motion (the boom will open less).
Loosening the grub screw 2 you delay the moment it will meet the mechanical end-stop of the operator during
opening stopping its motion (the boom will open more).
It is advisable to make the adjustments by tightening/loosening the grub screws 1-2 turns at a time to prevent
undesired and excessive effects.
It is advisable to use LOCTITE 243 (light) to guarantee stability of the long grub screws.
Remember to refit the short grub screws.
The mechanical end-stops must be after the end of motion to which the electrical limit switches are adjusted
(obligatory), therefore, the mechanical end-stops must be positioned slightly beyond the actual desired point of end
of motion.
CONTROL UNIT INSTALLATION
• Check that the power supply voltage and frequency are compatible with the control unit.
• Do not solder the ends of the cables that will be fitted in the terminal boards of the control unit.
The control unit is housed in a plastic container 1 (27) and is secured on the upright of the operator with four
•
screws 2 (27).
At least one hole must be made in one of the four pierceable areas 3 (27) to run the cables through.
•
• It is recommended to use appropriate cable ducts.
The control unit container must be closed with the cover 4 (27) using the screws 5 (27).
•
• Refer to the control unit manual for the electrical connections, use and programming.
Figure 28 shows the cables leading from the operator.
