Reaper Mechanical and Electrical Operations

Version 1.29 Last revision 26 Jan 2008

This document describes the installation, operation and maintenance of mechanical

and electrical equipment onboard the Reaper.

All aboard should be familiar with the contents so we can minimise the consequences

of Mr Cock-up, should he come aboard. An Engine Room Log is kept aboard

please use it for routine events such as running hours, fuelling, oil/coolant top-ups andthings that you break, fix or change. Daily and Weekly maintenance schedules will

accompany the log (specimens attached). Comments and updates are most welcome

(to [email protected], mobile 07764 161891).

Engine

The Reaper is powered by an 8 litre Daewoo L136 (serial no. 404807ENCKM) diesel

engine. It generates 160 HP at 2200 rpm into a DMT70T 3.46:1 reduction gearbox

(serial no. 04061129). The manual states a fuel consumption of 32 litres / hour.

Hydraulic and pneumatic power is taken from a Dong-I E087A/D Take Off (serial no.

01070035).

Operation

START UP

1) Ensure gearbox in neutral.

2) Key to ON.

3) Key to START.

4) Monitor engine panel and ensure cooling water is discharging.

SHUT DOWN

1) Press OFF button.

2) Key to OFF.

3) In case of fire the fuel valves may be remotely closed using the two toggles

next to the bunks in the aft cabin. This may result in the need for the fuel

system to be bled.

Bilge pumping

A bilge alarm float switch is located just above the electric bilge pump, close to the

base of the air compressor. Two switches on the Bilge Control Panel (a midships of

the 24v Control Panel) control whether the siren and/or the strobe light on the mitch

are in armed.

There are four ways of pumping the bilges.

Giljector

Engine cooling water passes through a Venturi system which uplifts bilge water

which is discharged, together with the cooling water, to the port side. Note that such

permanent discharge of bilge may be in contravention of harbour bye-laws.

Deckwash

Pump 2 is engaged via an electric clutch operated by a 24Vcircuit breaker (a flashing

LED signals when the clutch is engaged). This normally pumps sea water from the

port seacock up through to the deck wash hose. The end fitting of the deck wash may

connect to the fire hose fitting. However valves 4 and 5 can be set so that water is

drawn instead from the fore and/or aft bilges (see Figure 2). If valves 4 and 6 are left

in a half open position a back siphon can form which will flood the bilges and sink

the Reaper. Thus always ensure that valve 5 is fully closed when the bilges are not

Batteries

There are two separate 24V banks of lead acid batteries a starter set and a 150 Ah

AGM deep cycle lighting set. Both are charged by the alternator through a diode

splitter they are thus electrically independent. Alternator current is monitored bythe ammeter. The voltmeter can be switched to either battery or to off.

When shore-side power is on or the diesel generator is running, the batteries can also

be charged by the (110V input) Centaur 16A battery charger. This is an intelligent

charger which means two things. First, whilst not good practice, it will not be harmed

by starting the engine while charging. More importantly, it can be left on indefinitely

without harming the batteries. Furthermore, the two outputs of the charger are

of switch S2. As a safety feature, this switch is centre-off and therefore isolates the

two supplies. Thus, in theory, both shore-side and generator could be energised at the

same time without causing a bang - only one can be brought into circuit at any onetime. The voltage of whichever source is chosen is shown on the voltmeter (V1).

The 110-240V transformer may be switched in circuit to provide 240 V to run the

fridge, toaster and lifes other little essentials and also the emergency submersible

pump. However power tools or other heavy loads should be run directly from shore-

side power socket mentioned above. The key to the Anstruther shore-side power

distribution box is in the fwd cabin.

How to leave the Reaper

See Figure 3.

110V. Switch off shore side power by toggling the leftmost switch in the shore-side

power panel to Off (up).

24V. Switch off lighting battery set Isolator Switch (S1 vertical is Off). This

means that the gas alarm is also switched off and will bleep, and must be reset, when

the Isolator Switch is switched on again.
