A- INTRODUCTION
A.1 - Storage Instructions
1. The material has been shipped in good condition,protected against mechanical damage andcorrosion by appropriate packaging. The
consignee/shipyard shall inspect the materialupon delivery and make sure that:
- all items have been delivered as shown on thetransport documents
- no item has suffered any damage duringtransportation and handling
- all parts are free of corrosion.
Once the consignee/shipyard has accepted thedelivery of the goods, the consignee/shipyard willhave to make sure the goods are stored in goodconditions to prevent mechanical damage to and/orcorrosion of the goods. No dirt, dust, humidity or any
other matter must be allowed to penetrate into themechanical devices and/or electric or electroniccomponents.
2. Hydraulic machinery:Hydraulic devices (pumps, servos, valves, etc.)have been tested before delivery. Therefore, they
benefit from a natural internal oil film protection.However, this protection will last no more than 3months in a dry and sheltered environment. If thehydraulic units have been stored for more than 3months, they will have to be run under no-loadconditions, with fresh oil, to flush the entire systembefore the actual start-up. Oil and oil filter will thenbe changed before start-up!
3. If the hydraulic machinery is laid up for anextended period of more than 1 month, an anti-corrosion compound, such as Rust Veto Concen-trateby E.F.Hougton & Co. of Philadelphia, USA,
(or equivalent additive) should be added to thetank oil, and the system run without load for somelength of time, sufficient to circulate the added oilthrough the entire system.

training, (ZF training includes refresher andassessment courses), and is conducted at approvedZF training centres.
The ZF group has installed a network of fully staffedSales and Service Organisation Centres, (SSOCs), atstrategic locations throughout the world so that ourcustomers receive field support close to their geogra-phical location. Repair work carried out at ZF SSOCswill be guaranteed in accordance with the prevailingcontractual conditions.
Note :Damage resulting from work performed by non-ZF personnel and which is deemed by ZF to havebeen conducted in an improper manner, including allfollow-on remedial work, the costs thereof, loss of
vessel operational time and any associated loss ofrevenue including any and all third party liabilities,(consequential damages) are, in their entirety,excluded from the ZF contractual guarantee.
WARNING
Installation and Operation of the equipment, includingunauthorised modification, that is outwith theparameters described in this manual, (plus anypertinent ZF Marine Propulsion Systems technicaldata and the sales contract , including any relevantamendments/revisions), may result in irreparabledamage to, and/or malfunction of the equipment. Such
actions may result in invalidation and rejection ofexisting warranty and any warranty claims, solely atthe manufacturers discretion.
ADVISORY
Should any installation, operation, maintenanceand/or modification work be considered by end users,or any third party then ZF Marine Propulsion Systemsstrongly recommends that such work only beundertaken in full agreement with the expresspermission, in writing, of the manufacturer, ZFMasson S.A.

A.5.1- Mechanical System
The KH type propeller system includes a hydraulically operated controllable pitch propeller and hollow propellershaft or "line shaft", through which it is mechanically linked to a propulsion gearbox.
The gearbox output shaft is rigidly linked to the line shaft, which is a monoblock part running all the way throughthe stern tube to the propeller hub. The propeller hub (i.e. the propeller) is bolted to the propeller shaft.A hydraulic actuator piston inside the propeller hub moves back and forth to swivel the propeller blades so as to
change the propeller pitch, through a yoke and crank assembly.The line shaft and gearbox shaft are hollow to allow oil pressure for propeller pitch adjustment to run through theshafts, from the OD box at the front end of the propulsion gearbox to the actuator cylinder located inside thepropeller hub. The central feeding pipe moves fore and aft with the actuator piston, so that, at the same time, itprovides an accurate indication of the propeller pitch.

A.5.2- Hydraulic System
Propeller actuation is provided through hydraulic pressure acting on the piston inside the propeller hub.
A main oil tank containing the hydraulic fluid supplies the operating fluid to the system. Operating pressure issupplied by an independent, electrically driven variable displacement oil pump (P1) fitted as a part of thehydraulic control unit. An identical stand-by oil pump assembly (P2) is installed in parallel with the mainoperating pump and is controlled through a pressure switch connected to the CPP main hydraulic control block.
Emergency actuation is possible by means of a hand pump (PM).
A pressure regulator (LP1) placed parallel to the oil filter (FLT) sets the maximum operating pressure limit. Oilexiting from the oil filter passes through a flow control valve (LD1) before it reaches the distributor solenoidvalves (D1). The flow control valve determines the speed of the propeller adjustment. It has been set in ourfactory.
The distributor solenoid valves are energised with 24 V DC to direct oil under operating pressure throughpressure outlets (A) or (B) to the propeller pitch servo, as requested by the operator, until the desired propellerpitch is reached.
Hydraulic pressure is carried to the servo chambers through the propeller shaft, where two concentric channelsare formed in the centre of the shaft. Both channels open at the front end of the propulsion gearbox output shaft,into the manifold or O.D. box. In this way, oil under pressure can be supplied from the engine room to either of
the servo chambers in the propeller hub.

CPP Control System MRCS 08/90 General description
The Manual Control of CPP is possible from the local side. Automatic control is possible from the ECR Panel,from Wheelhouse Panels as well as from the WING via a Control Lever.
Change-over from ECR to the Wheelhouse is made by a selector switch LOCAL/REMOTE on the Engine. Thechange over between ECR, W/H Panel and Wings is made by pushbuttons incorporated in the control panels.
This change over is interlocked by the control lever positions UP / DOWN, which must be in similar positions.
The CPP control is possible only if the engine is running (system without clutch), indicated by a lamp installed inthe control panels. Zero position of the CPP is indicated in the panels and will interlock Engine start.
The Electronic Unit is to be installed in the Engine Control Room Console and contains all electronic PCBs forthe CPP Control System MRCS 08/90 .
The Microprocessor controlled System will activate the Hydraulic Solenoid Valves for AHEAD and ASTERNmovement of the CPP. The feedback from the CPP position transmitter is supplied to the control system andregulates the position of the CPP.
The control of CPP is monitored by an incorporated overload detection with Automatic Slow Down.
In the wheelhouse panels a Back-Up control of the CPP is provided by Joystick, which can be activated by a
covered switch.
Indicators for Shaft RPM and CPP angle are installed in or near the Control Panels.
The Engines are to be started locally. After Starting of the Hydraulic System for the CPP, the Engine and CPPcan be operated manually in the Engine Room.

After changing the LOCAL/REMOTE Switch to Remote, the Control can be taken over by one of the ControlPanels or the Wings, provided that the relevant Control Lever is at Zero Position, the Engine is running and theCPP Hydraulic Pressure is available. Take Over is executed by pressing the relevant pushbutton ECR, W/H orWING.
