INTRODUCTION
The Clipper Echosounder is supplied complete with display unit,
transducer and alarm. It is intended for 12V ship’s supply operation
although, because of its lower power consumption, it can be run
from an external dry battery.
INSTALLING THE DISPLAY
Select a convenient position for the display on a panel or bulk-
head.
The site must be flat and the cavity behind the panel must remain
dry at all times. (The cable entry is deliberately not sealed to
ensure adequate ventilation. This prevents misting of the display).
Cut a hole in the panel 87mm wide and 67mm deep. Bring the
wiring through the hole in the panel and connect the black wire to
negative and red to positive. (See Figure 1). It is wise to use a fused
supply to provide protection should a fault occur. The current
consumption is very small, so a 1/4 Amp fuse is more than adequate.
The red wire of the alarm bleeper is also connected to the positive
supply, as shown on Figure 1. The black wire of the alarm bleeper
connects to the green wire from the display unit. The alarm bleeper
is not watertight and must be mounted in a protected position.
