Notes:
(1) Signal number shows the interface to the remote control (see 4003−2).
(2) Function:
SLD = Slow down
SHD = Shut down
ALM = Alarm.
(3) Type of signal:
D = Difference in value
F = Failure
H = High
L = Low.
(4) Alternative design.
(5) Not included in standard engine supply range.
(6) Abbreviations:
TC = Turbocharger
SAC = Scavenge Air Cooler.
(7) For the location of measurements and signal numbers, see 8016−1,
paragraph 4 Servo Oil Leakage and 8019−1, paragraph 4 Fuel Leakage
System.
(8) Supply from the board system for control and air spring air through the
pressure reducing valve 35−23HA.
(9) Supply from starting air pipe upstream of the shut-off valve (from starting
air bottles 930-B001 and 930-B002) for control and air spring air through
the pressure reducing valve 35−19HA.
(10) Signal designation changes downstream of the amplifier (on the engine)
from TExxxxA to TTxxxxA.
(11) Alarm has an effect only above 30% engine power.
(12) Alarm has an effect only above 40% engine power.
(13) The alarm and slow-down values shown are the minimum settings
permitted (from the TC manufacturer). To get a warning in a shorter time,
the ALM and SLD values can be increased up to 0.4 bar below the
minimum effective pressure (measured in the full operation range). The
last ALM/SLD setting is found during commissioning / sea trial of the
vessel.
(14) Alarm has an effect only above 40% engine power.
(15) This data is applicable only to engines with a CMCR in the range between:
D more than or equal to 66.0 rpm (CMCR speed ≥ 66.0 rpm) and
less than or equal to 70.5 rpm (CMCR speed ≤ 70.5 rpm)
For these engines an external crosshead lubricating oil booster pump is
installed.
(16) This data is applicable only to engines with a CMCR in the range between:
D more than 70.5 rpm (CMCR speed > 70.5 rpm) and
less than or equal to 75.0 rpm (CMCR speed ≤ 75.0 rpm)
For these engines an external crosshead lubricating oil booster pump is
installed.
(17) The alarm value can be different. For the applicable setting value, refer to
the specification of the damper manufacturer.
