Chapter 1: Operation
1.1 Getting started
This handbook describes how to operate, maintain and install the Raymarine
ST60 Rudder Angle Indicator Instrument. The instrument provides a real-time
indication of rudder position as determined by the associated Rudder Reference
Transducer.
CAUTION: Calibration requirement
The ST60 Rudder Angle Indicator instrument is calibrated to
factory (default) settings when first supplied. To ensure optimum
performance on your boat, this product must be calibrated before
use. Do NOT use the product until it has been calibrated using the
procedures in
Chapter 4, Calibration
.
Displayed information
The ST60 Rudder Angle Indicator pointer shows the rudder position in real-time.
The instrument scale range gives an expanded indication from -40
° to +40°
about zero.
Operation with other instruments
When the ST60 Rudder Angle Indicator is connected to an operational autopilot
via SeaTalk, the instrument acts as slave to the autopilot, which receives data
from the Rudder Angle Indicator Transducer and passes the information via the
SeaTalk bus.
1.2 Normal use
As the ST60 Rudder Angle Indicator operates in real time, very little operator
action is necessary during normal use except to observe the instrument as
required to ascertain the rudder angle.
Note:
If rudder angle information is not available on the SeaTalk bus, the analog pointer
oscillates ±10° about the top of the dial.
The key is the only key used during normal operation (see
Key functions
illustration). The
set, < and > keys are reserved for calibration mode, see
Chapter 4, Calibration
. All key presses called for in this handbook are momentary,
unless otherwise stated.
