5.9 Controls
5.9.1 General
Three-phase, two-speed hoists are available for most three-phase power supply voltages. The controls of
two-speed hoists
cannot be connected to more than one power supply voltage.
The control panel layouts and wiring diagrams found in this manual are for standard hoist controls. The hoist
motor brake rectifier is part of the PC (printed circuit) board assembly.
5.9.2 Control Fuses
The control fuse for Three-Phase control panels is located in a vertical, cylindrical fuse holder labeled
F100. This is mounted to the printed circuit board. The top rotates loose for replacement. See Section
5.10 for location.
The control fuse for the Single-Phase 115V control panels is installed as an in-line fuse holder on a wire.
The in-line housing separates for replacement. See Section 5.12 wiring diagrams for wire location.
