Hydrological Services Pty Ltd Sydney, Australia

1. Hydrological Services Pty Ltd Sydney, Australia Hornet Cableway Gauging Systems Set Up and Use Department of Primary Industries and Water Hobart, Tasmania 31st August 2009

2. Hornet V Hornet Plus Comparison

3. Hornet (Basic) System • Suitable for ADCP only • Used for positioning only • No airline / wetline correction feature • Variable traversing speed (maximum 1m/sec) • Wireless hand-control

4. Hornet Plus System • Suitable for ADCP OR conventional current meter • Auto-correction of distance and depth (air / wetline) • Variable traversing speed (maximum 1m/sec or 3.28ft /sec) • Wireless hand- control • Depth Measurement Resolution (0.01m OR 0.01ft) • Built-in Signal Processor for Mechanical Current Meters

5. Set-Up – Install Hoist Batteries It may be necessary to connect power to drive control and retrieve traveller block from middle of stream 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

6. Set-Up – Install Hoist

7. Set-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) Battery Mounting Boxes Extension located between traveller block and hoist Hand Winch Mounting Box Attaches to traveller block

8. Set-Up – Install Hoist

9. Set-Up – Drive Control Interlock Interlock serves 2 main purposes • In built ultrasonic proximity sensor prevents traveller block striking drive control cabinet (when activated) • 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

10. Set-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 and pull down on connector Remove ‘R’ clip and pin from connector Press Lower to release connector

11. Set-Up – Attach ADCP

12. Operation – 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

13. Operation - Hand Control Features LCD (view Distance, Angles of Sag/Drift, Speed, Voltage & Status) Variable Speed Control Power & Zero Button (turns power On/Off & ‘Zeroes’ distance/depth when prompted) Navigate Menus (rotate to scroll through menus and press to select options) LED’s - RED indicates an error - GREEN flashes while communicating Traveller Switch (forward/reverse) Hoist Control Switch (raise/lower weight)

14. Operation – 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)

15. Operation – Brief Description of Controls (continued) LCD + backlight –backlight can be always OFF, ON or for several seconds horizontal distance data displayed (Basic Hornet) Current meter Input and Output – Hornet Plus only Operating Frequency – system uses 915MHz licence free radio band

16. Operation – Brief Description of Controls (continued) NiMh Battery charging – charged by either mains charger or 12VDC ‘cigarette lighter’ charger provided alkaline batteries can be used (ensure that charger is NOT connected

17. Operation – Menu Operation

18. Operation - Horizontal Distance Correction • Inclinometer attached to main cable measures ‘angle of sag’ • Trigonometry used to constantly correct ‘raw’ horizontal distance to ‘true’ horizontal distance ‘W = L Cos θ’ • Both ‘raw’ and ‘corrected’ distance displayed on hand control W θ L ← 10.30m 0.53m/s ↨ 3.72m R[ ] H[ ]

19. Operation - Airline / Wetline Correction • Inclinometer inside hoist constantly measures ‘angle of drift’ • Trigonometry used to correct ‘raw’ airline and wetline depth to ‘corrected’ depth • Both ‘raw’ airline / wetline depth, ‘corrected’ depth and ‘corrected depth to current meter’ displayed on hand control as shown • Corrected depth calculated in accordance with USGS ‘Measurement and Computation of Stream Flow Vol.1, Water Supply Paper 2175’ Main Cable θ Airline A 3.75 W 2.53m CTD 2.51m 5.5° Corrected Depth Wetline Water Flow

20. Operation - Current Meter Signal Transmission (Hornet Plus only) • In-built current meter signal processor (i.e. filters signal) • Continuous signal counting (regardless of communication status) • Any type of current meter counter can be used To current meter counter Radio Communications

21. Operation - Drive Control System Control Box (front view) Drive Control ‘Inter-lock’ Control Box (side view) Portable Generator (240V or 110V) AC Electric Motor, Encoder & Controller
