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.

Two-speed hoists are available for 208, 230, 460, and 575 volt three-phase power supplies. The two-speed

hoists can only be connected to the specified serial plate voltage.

Three-phase single-speed hoists are available and re-connectable for 208, 230, and 460 volts. Single-

phase single-speed hoists are also available with 115 volt one-phase power supply.

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. There are two holders identified as position F100 or F101. The supply voltage

determines which location the fuse is inserted. 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.

The control fuse for the Single-Phase 115V control panels is located in a fuse holder attached to the din rail

beside the contactor. See Figure 3 Section 2.7. The top of the fuse holder flips open so that a fuse can be

removed or installed.
