5.6 Type 04−B: fuses for the pilot solenoids
The pilot solenoid coils of the valve terminals of type 04−B are
fused separately with (quick acting) 0.315 A fuses. These
fuses are situated on the printed circuit board (behind a
cover) in each manifold sub−base. Each single−solenoid mani
fold sub−base is fitted with one fuse; each double−solenoid
manifold sub−base is fitted with two fuses.
Replacing defective/burnt through 0.315 A fuses
In order to replace burnt through fuses, proceed as follows
(note also Fig. 5/8).
1. Switch off the compressed air supply and the power sup
ply (connections 1 and 2).
2. Open the cover of the manifold sub−base.
3. Carefully remove the defective/burnt through fuse from
its base (see diagram).
4. Insert a new (quick−acting) 0.315 A fuse.
5. Close the cover.
