SB360

Information

When installing a new series 3A "B" box PCB, Kit EL-37099 into an existing SB-360/MK6 there may be some wiring modifications required.

Changes to be made depend on:

Traverse Type employed
Whether safety feature function is required

Traverse Type

Traverse type can be either:

Type

Description

Action

Rack Shift

These units that have hydraulic motors and a rack and pinion to traverse cranes.

D8 and D15 located near C6 need to be removed from the circuit.

Note: Failure to carry out this small modification may result in damaging the rack and pinion system

Ram Shift

These units that have hydraulic rams to traverse cranes.

None required - diodes can be left installed on board as delivered.

Safety Feature Installation

The replacement PCB has the facility to provide an extra safety feature not available on earlier units. This is an interlock between the arm functions and the stabilizer legs, to decrease the chance of "roll over" due to incorrect deployment of stabilizer legs.

Steelbro recommends that you install the PCB with the extra safety feature.

Installing the PCB with the safety feature

Remove bypass circuit fitted from C5/7/E to C5/15/E by reinstating wires 7 and 15 to C5/7/E and C5/15/E respectively. An extra kit is required, which includes micro switches etc, which would need to be fitted to the Stabilizer Legs.
