7.10 Control Changes and Fuses
The control panel components are assembled onto a Printed Circuit (PC) Board. The layouts and wiring
diagrams found within this section are for standard hoist controls. The hoist motor brake rectifier is an
integral part of the Printed Circuit (PC) Board.
Stepless hoists are available for the 460 volt three-phase power supplies. The stepless hoist can only be
connected to the specified serial plate voltage.
7.10.1 Control Circuit Fuses
The control fuse for three-phase control panels is located in a vertical, cylindrical fuse holder mounted to the
printed circuit board. The fuse holder is identified as position F100. See Figure 20 for a typical panel view.
The top rotates loose for replacement. There is only one top; therefore, the fuse is located in the position
with the top.
