POWER CONECTIONS TO HYDRAULIC MOTOR
A basic hydraulic schematic is shown in Appendix C.
Port sizes on the hydraulic motor and minimum hose
sizes are specified in Section 1.3.
The motor has pressure and return ports (bigger)
and a case drain ports. The pressure and return
ports should be connected to a solenoid controlled
valve (not supplied by Maxwell).
After connecting the power lines, spray all ports and
fittings with anti-corrosive waterproof coating, "CRC
3013 Soft Seal" or equivalent.

INSTALLATION OF CONTROLS
The windlass can be operated using:
Deck mounted footswitches
Hand held pendant controller (single or dual
speed)
Helm switch (single or dual speed)
Chain counter
These control accessories are available from
Maxwell customised to suit your windlass.
It is the choice of the designer/builder to use one,
two or all three of these controls. They are wired in
parallel to the directional valve (for hydraulic
windlasses) or to the starter unit (for electric
windlasses). The controls can work on 12 or 24V
power supply.
If footswitches are used, then an isolator switch for
them must be installed in the wheelhouse, to prevent
operating the windlass by someone accidentally
stepping on the footswitch.
Hand held pendant controller is often the most
convenient way of operating the windlass. Maxwell
offers several variations of pendants, including single
speed, dual speed, single pendant for running a pair
of windlasses, pendants with auxiliary buttons which
can be used for starting chain wash system,
hydraulic pump etc. They are supplied with a plug on
the other end of cable and a matching waterproof
socket, which should be installed on a convenient
location on the deck.
All units are supplied with detailed wiring instructions
to assist installation.
Refer to wiring schematics in Appendix C for control
circuits. All control wiring should be done using no
smaller than 1.5mm² wire (AWG 16).
Where applicable, a manually re-settable, ignition
proof 3A breaker or fuse should be installed on the
power supply line for controls, within 1m (40") from
the main breaker/isolator. These requirements are
mandatory to meet USCG, ABYC and NMMA rules.
After connecting the power lines, spray all ports and
fittings with anti-corrosive waterproof coating "CRC
3013 Soft Seal" or equivalent.
