4.1 Starting up
The chain counter features a graphic display and three keys: (ON), (UP) and (DOWN). There
is also a buzzer that indicates the pressing of the keys or attracts the user’s attention in particular conditions
(alarm triggering). The ON key switches on the display and enables the other two keys. It must be used to
access the parameter setting menus. For selecting the parameters to be modified and to confirm the values
set. The display backlight will switch off 30 seconds after the last command given (adjustable default time – see
“Light Time”).
The UP key commands the hoisting of the anchor and the DOWN key casts it. When the key is released, the
action is stopped. During parameter setting, the two keys allow the User to move around the menu and vary
parameter values.
When switched on, the instrument will make a beep and the following page will appear for a few seconds:
Once the initialisation procedure is complete, the main page will appear.
Where:
STATUS: indicates the status of the instrument and any failure.
SPEED’: indicates the chain speed during hoisting or lowering in meters per minute or feet per minute.
COUNT: indicates the measurement of the chain lowered (in metres or feet).
MONITORING: indicates the power supply voltage of the instrument and the power supply voltage of the boat.
ICONS: this is the part of the display bearing the icons that indicate the hoisting or casting of the anchor and any failure.
When the instrument is turned on for the first time, it will set up as programmed in the factory (see table).

3.3 Installing the chain counter
For instructions on making electrical connections, see Chapter 7- WIRING DIAGRAM. The wires must have a minimum cross section
size of 1.5 mm². Install a 5 A (ampere) fast safety fuse on the positive (+) wire of the battery. Do not use the voltage generated by the
engine battery set to provide power.
Series resistor recommended for >5m sensor cable length.
The instrument complies with EMC standards and must be positioned at a distance of:
- 30 cm (~1 Ft) from the compass; -50 cm (~1.5 Ft) from radio equipment;
- 2 metres (~6.5 Ft) from radio transmitter equipment; -2 metres (~6.5 Ft) from the radar beam.
- Transmission frequency 433MHz
The chain counter must be positioned so that the
display will be easy to read. It should not be exposed
to direct sunlight. Secure the instrument in place
with the cradle provided, tightening the two
screws using a cross screwdriver.
