INSTALLATION
8.2 Connecting the control unit valves
• Use ARAG valves: use of unsuitable valves not provided by ARAG automatically voids the warranty.
ARAG is not liable for damages to the equipment, persons, animals or things caused by failure to observe the above instructions.
• All valve connectors must be provided with seals before being connected (Fig. 12).
• Make sure the seals are correctly fitted to avoid water infiltration when using the control unit.

Connector 1 shall control the valve which in turn is
connected to the boom section 1, and so on with
the other valves.
Connect
"connector 1" to "valve 1", and then the
other connectors, with rising numbers from left to
right:
the boom section 1 is the left one looking
the machine from the rear side (Fig. 11).
Fig. 12
Fix the connectors to the relevant valves according
to the initials indicated in your assembly general
diagram (Par. 6.1 System recommended
composition).
• Remove the protection cap ( 1, Fig. 12) from the
electric valve.
• Place the seal (
2) onto the connector (3) and push
the connector fully on ( 4): be careful not to bend
the contacts upon insertion on the valve.
• Tighten the screw (
5) fully home.
If the number of monitor switches is greater than the number of section valves, connect cables as specified in Tab. 3.

• ONLY FOR SEQUENTIAL VERSION:
CAUTION!
The section valves and main valve connected to the computer must be the 3-wire type (valve code ends with letter "T").
When there are less than 13 section valves to be connected, always begin by connecting section 1 and then proceed in
sequence until connecting the last section.
Example:
- Connection sequence for 8 valves: sect. 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8
- Connection sequence for 11 valves: sect. 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 etc.
