The SKIPPER Compact speed log family is a set of speed logs designed to have
a minimal footprint on the bridge consoles, but still keeping full functionality. This
manual covers two systems, built up of the same electronic units and wiring
methodology, with one of two sensor technologies.
a) EML224 is a system using electromagnets to generate a current
proportional to speed in the water, in one or two axis.
b) DL1 is a system using a small Doppler sensor, working in the ships axis
to provide speed through water. It use acoustic signals and measures the
Doppler shift of the particles in the water.
The hardware is compatible between systems (excluding sensor) while CD401
displays its version CD401XX-XB or later. However the code (code = software
activation code) will be different and can be supplied from SKIPPER for retrot.
1. The mounting; Either a sea valve or tank. Welded to the bottom of the hull
with the correct orientation.
2. The sensor; A speed sensor device designed to t into the mountings.
3. The Electronic unit (JB60CD); The JB60CD allowing the EML 224
Compact (EML224 Compact = Compact speed log) to be powered and
interfaced to the other navigation systems using digital standards.
4. The CD401XX Compact display; An alphanumeric display unit allowing
the bridge staff to view the data.
The EML 224 Compact (EML224 Compact = Compact speed log) is unique in
its simple, yet exible way to display vital data in almost all conditions.
