6 ROUTING THE CABLES
6.1 Routing recommendations
If, due to limited space, the cabling has to run around a corner, make sure that the bend is
•
not too sharp as this may cause breakage of the cables;
Make sure the cabling cannot come into contact with moving parts;
•
Route the cables in such a way that twisting and machine movements cannot damage or
•
break them;
Take care not to break, pull, tear or cut the cables.
•
Routing the cables to protect against water in ltrations:
The branch of the cables running to the valves must always be DOWNWARDS at the end
(Fig. 3).
Fig. 3
• Use only the cables provided with the ARAG control box.
• Use of unsuitable cables or cables not provided by ARAG automatically voids the
warranty.
• ARAG is not liable for damage to the equipment, persons or animals caused by
failure to observe the above instructions.

6.2.7 Operating modes
Control boxes can operate in “M” or “P” mode, depending on power cable connection (par.
6.2.8).
• “M” mode of operation:
Section valves are closed or opened from the main switch provided that section valve switches
are set in the appropriate position; in other words, if section switches are set to OFF (lever down),
operating the main switch does not affect the sections. If one or more section valve switches are set
to ON (lever up), opening or closing the main switch opens or closes the section valves as well.
• “P” mode of operation:
section valves are operated independently.
Main switch control functions do not affect section valve opening or closing.
6.2.8 Setting “M” or “P” operation mode
The power cable has an additional wire for operating mode setting (par. 6.2.7).

9 USING THE CONTROL BOX
CAUTION:
The control box is equipped with an internal self-resetting safety device that cuts the
power in case of operational defects or problems.
If the safety device starts up, all the warning lights on the box go out, but since no
other signal is provided for, the operator must pay attention that the box is still active and that when a command is selected on the box the action is performed by the
system. If the control box goes off due to the safety device and the operator wishes
to stop spraying (if in operation), he must do so by acting on the pump.
If the internal safety device starts up, it is necessary to remove power from the box
(by turning off the tractor) and wait at least 20 seconds before restarting.
Should the problem persist, contact the nearest aftersales service.
