Page 5: Introduction
Where needed, there are references to detailed information and fig- ures contained in the WorkHorse Technical Manual. WorkHorse Sentinel deployments are most often Self-Contained but can be Real-Time. Typically, deployments are considered to be Self-Contained when the ADCP is remotely deployed and powered using internal batteries. -
Page 6: Workhorse Sentinel Adcp Applications
WorkHorse Sentinel User's Guide WorkHorse Sentinel ADCP Applications The WorkHorse Sentinel ADCP is designed so that it can be used as a fully self-contained system. This means that it contains its own battery for power and internal recorder for the storage of all data that you have set it up to col- lect. -
Page 7: Table 2: Workhorse Real-Time Application Guide
WorkHorse Sentinel User's Guide The WorkHorse Sentinel ADCP is also able to be used in real time applica- tions that either take advantage of the internal battery power, or external battery power, and can be used to collect data internally as well as exter- nally. -
Page 8: System Overview
WorkHorse Sentinel User's Guide System Overview The Sentinel ADCP system consists of an ADCP, cables, battery pack, flash memory card, and software. Both battery capacity and memory can be in- creased with upgrades for longer deployments. The Sentinel can also be used for direct-reading current profile operation. -

WorkHorse Sentinel User's Guide I/O Cable Overview Always remove the retaining strap on the end-cap underwater-connect cable and dummy plug when disconnecting them. Failure to do so will break the retainer strap. Do not apply any upward force on the end-cap connector as the I/O cable is being disconnected. -
Page 11: Battery Pack Overview
WorkHorse Sentinel User's Guide Battery Pack Overview WorkHorse Sentinel ADCPs require +20 to 60 VDC to operate. The stan- dard AC Adapter runs on any standard AC power and supplies +24 VDC to run the Workhorse when the batteries are not connected. -
Page 12: Flash Memory Card Overview
WorkHorse Sentinel User's Guide CAUTION. The Workhorse Sentinel battery pack is held in place by four sets of washers, lock washers, and wing nuts. If the wing nuts are not tight, the assembly of washers and wing nut can become loose and eventually fall onto the PIO board. -
Page 13: Workhorse Care
WorkHorse Sentinel User's Guide WorkHorse Care This section contains a list of items you should be aware of every time you handle, use, or deploy your WorkHorse. Please refer to this list often. General Handling Guidelines • Never set the transducer on a hard or rough surface. The urethane faces may be damaged. -
Page 14: Deployment Guidelines
WorkHorse Sentinel User's Guide • Place a light amount of DC-111 lubricant on the end-cap connector pins (rubber portion only). This will make it eas- ier to connect or remove the I/O cable and dummy plug. • Do not connect or disconnect the I/O cable with power ap- plied. -
Page 15: Setup The Workhorse Sentinel Adcp
WorkHorse, use WinSC’s Auto Detect, which searches for the WorkHorse’s current serial port and baud rate. . The WorkHorse Sentinel is normally set for RS232, but it can be RS422 changed to RS422 by changing a switch setting. The switch is in plain view on the top circuit board, near the cable connectors. -

Page 24: Compass Calibration
WorkHorse Sentinel User's Guide Compass Calibration The main reason for compass calibration is battery replacement. Each new battery carries a different magnetic signature. The compass calibration al- gorithm corrects for the distortions caused by the battery to give you an ac- curate measurement. -
Page 25: Compass Calibration Procedure
WorkHorse Sentinel User's Guide can be vertical (it can rest on its end cap), or it can be tilted (it could rest on a transducer face). Whatever its tilt, the tilt must remain constant as you rotate the WorkHorse. When prompted, rotate the WorkHorse smoothly and slowly. -
Page 26: Figure 8. Compass Alignment
WorkHorse Sentinel User's Guide e. The second rotation requires the WorkHorse to be tilted on an adjacent beam. Follow the on-screen instructions to orient the unit correctly. Tilt an upward-looking WorkHorse with a block under one side of the end cap. -
