Limit Switches (Directly Related To Top)

The total opening/closing function for the top consists of 3 sub-functions:

• Open top (deposit in top compartment) or close top (move toward windshield frame).
• Open/close cloth holding brace.
• Open/close top compartment cover.

Each of these sub-functions has 3 positions signalled by limit switches:

• OPEN, i.e. completely opened.
• CLOSED, i.e. locking pins inserted into locks. The locking operation can start.
• LOCKED, i.e. the associated lock is locked mechanically.

The following limit switches are required for these sub-functions:

• Cloth holding brace OPEN/CLOSED/LOCKED.
• Top compartment cover OPEN/CLOSED/LOCKED.
• Top OPEN/LOCKED.

A limit switch for TOP CLOSED is not required because the front locks are designed differently than the center and rear locks. The TOP UP limit switch is a special feature. After reaching this limit switch the hydraulic cylinders for the top drive are switched over to differential operation (e.g. pressure in cylinder is reduced by approximately 50 percent) during the operation CLOSE TOP.
