Set-Up – Install Hoist BatteriesSet-Up – Install Hoist Batteries
Install the 1st battery opposite to the winch side Secure by locking in pin
Install the hand winch in the battery box with the slot provided
Install the 2nd battery above the hand winch and lock in place with pin
It may be necessary to connect power to drive control and retrieve traveller block from middle of stream
Set-Up – Install HoistSet-Up – Install Hoist
Set-Up –Hoist ExtensionSet-Up –Hoist Extension
Used where operating side platform is ‘high’ above ground level
Minimises OH&S risk from need to lift batteries and hoist to platform during assembly tasks
Needs to be factored into hand control setting prior to gauging (Hornet Plus systems only)
Hand Winch Mounting Box
Attaches to traveller block

Set-Up – Drive Control InterlockSet-Up – Drive Control InterlockInterlock serves 2 main purposes
1. In built ultrasonic proximity sensor prevents traveller block striking drive control cabinet (when activated)
2. In built ‘tilt’ sensor senses horizontal sag angle for auto correction of horizontal distance
Ensure underside of main cable makes contact with BOTH bottom Interlock studs
Set-Up – Attach ADCP to HoistSet-Up – Attach ADCP to Hoist
Open bottom cover on hoist and press button on control box to switch on power to hoist (BLUE L.E.D. is illuminated)
Press Lower to release connector
Remove ‘R’ clip and pin
from connector
Press Lower and pull down on connector

Operation – Initial Power UpOperation – Initial Power Up
Apply power to Drive Control System by connecting portable generator
Switch on Hoist (button on control box)
Switch on Hand Control (blue button in top right hand corner)
Red L.E.D. on the hand control will turn off once communications have been established
Green L.E.D. will flash as the remote control communicates between the Hoist and Drive Control System

Operation – Brief Description of ControlsOperation – Brief Description of Controls
Power + Zero – turns unit On/Off when ‘zero’ is required the user will be prompted with a ‘z’ on the LCD
Traversing Speed – controls speed of traverse (maximum 1 metre per second) constant speed required for ADCP gauging
Forward and Reverse Traversing – forward (from operating to far side reverse (from far side to operating side
Raise and Lower – raises and lowers current meter (constant rate)
Red, Green and Blue L.E.D.’s – red indicates a communication problem green indicates all OK blue indicates pulses from current meter (Hornet Plus only)
Menu navigation – selection made by ‘rotate and press’
Sounder – Hand Control has in built sounder which beeps for each current meter count (Hornet Plus only)
