Figure 18. Power supply board with control voltage fuse
The control voltage fuse (1) is on the chain hoist power supply board, on the brake side of the
chain hoist.
1. Disconnect the chain hoist from the main power supply network.
2. Remove the fuse gently from its holder.
Make sure that you do not damage the other components.
3. Check the condition of the fuse.
Glass fuse
3.1 Check the fuse for burn marks.
If burn marks can be found, the fuse is blown. Replace the fuse.
3.2 Check the filament.
If the filament is inconstant, the fuse is blown. Replace the fuse. If the filament is
constant and there are no burn marks on the fuse, the fuse is in good condition.
Ceramic fuse
If a ceramic fuse is used, use a continuity checker, a multimeter, or an ohmmeter to check
the condition of the fuse.
▶
Continuity checker: Connect the leads to both ends of the fuse. If you cannot hear a
beep, the fuse is blown.
▶
Multimeter or ohmmeter: Connect the leads to both ends of the fuse. Set the meter at 1
Ω. If the meter shows a value that is close to 1 Ω, the fuse should be in good condition.
If no value is shown, the fuse is blown. Replace the fuse.
4. If the fuse is blown, replace it with a new one.
Check the correct rating for the new fuse from the blown fuse.
5. Place the new fuse gently to the holder.
6. Connect the chain hoist to the main power supply network.
