Electrical Junction Boxes - Analogue

The figure below shows the location of the electrical junction boxes on the Sidelifter. The state of the LEDs in the E box, and the C and D boxes can be used for initial fault finding.

Junction Box B

This is the main junction box containing most of the fuses and relays.

• Relays are lit with a GREEN LED when energised.
• Fuses are lit with a RED LED when they are blown.

Junction Box E

• Junction Box E is a simple junction box located between the B box and the powerpack.
• It also houses R33 which is the engine start relay.

Junction Boxes C & D

• These simple junction boxes are located on crane modules. They connect sensor inputs and hydraulic valve controls on the crane modules to the multicore cable running back to the main control box (B).
• They contain no fuses or relays.
