- In the box: radio chain counter; fastening kit (1 bracket with 2 screws); power adaptor for charging the lithium-ion battery; receiver power unit; magnetic sensor; magnet; horizontal-shaft windlass sensor support; instructions.
Magnet & Sensor
- Some windlasses come with sensor and magnet already fitted (chain counter setting): skip this step.
- Drill a 6.5 mm (~1/4") hole, 8 mm (5/16") deep, in a gypsy tooth outside the chain's path; on horizontal-shaft windlasses, in the outer circumference of the gypsy.
- Make sure the protruding magnet cannot hit the base or sensor as the gypsy turns.
- Insert the metal part of the magnet, leaving the protected part about 2 mm proud; fix with two-component epoxy for metals or silicone, marine grade.
- Horizontal-shaft windlasses: drill a 4 mm (~3/16") hole in the cover for the sensor cable; fit support Part A with its two screws over the O-ring; cut Part C to length with a hacksaw; glue Part C and the sensor in place with two-component epoxy for plastic or silicone.
- Set the sensor about 3 mm (~1/8") from the magnet.
Chain Counter & Receiver
- Place the chain counter where the display is easy to read, out of direct sunlight; secure it with the bracket and two screws.
- Wires at least 1.5 mm²; 5 A fast fuse on the battery positive. Do not power it from the engine battery set.
- EMC (EN55022) distances: 30 cm (~1 Ft) from the compass, 50 cm (~1.5 Ft) from radio equipment, 2 metres (~6.5 Ft) from radio transmitters and from the radar beam.
Junction Box Connections
| Pin | Signal |
|---|---|
| 1 | + battery |
| 2 | − battery |
| 3 & 7 | Magnetic sensor |
| 8 | UP command |
| 10 | DOWN command |
| 9 | − battery |
From the wiring diagram (version 4.00): UP and DOWN go to the windlass control box B2/B3 with C as common, a 5A fuse and switch on + battery, optional external remote switches in parallel.
Operation & Menus
- Three keys: ON (display on, enables the other keys, enters and confirms menus), UP (hoist) and DOWN (cast). Releasing UP or DOWN stops the windlass.
- Main page shows STATUS, SPEED (m/min or ft/min), COUNT (chain out), MONITORING (instrument and boat supply voltage) and direction/fault icons.
- Hold ON for six seconds for the setting menu; DOWN/UP to move, ON to select and confirm, Exit to go back.
- Backlight goes off 30 seconds after the last command (adjustable). Changing the language restarts the remote.

Enter the gypsy circumference in the Sensor Calibration menu; factory setting 33,0. Values are indicative; for an accurate figure the manual refers to a formula based on the R value and the chain internal length (printed incompletely as "(G value) = * R value* Chain Internal Length").
Troubleshooting
| Display | Fault | Corrective action |
|---|---|---|
| No Sensor | UP or DOWN pressed but no signal from the magnetic sensor for more than 5 seconds | Check the sensor connections and the sensor itself (replace if faulty); check sensor and magnet position and their 3 mm gap; check the electrical installation and the windlass. |
| Low Voltage | Supply voltage below 10Vdc | Check the battery charge and the electrical system. |
Warranty: 2 years.
