Safety Instructions
Please respect all instructions in this manual .
All texts marked with this symbol should have your
special attention. They are an indication of particular
importance regarding the operation of the system
and for your safety.
Good seamanship is essential! The use of the sumlog does not relieve
you of your responsibility for your ship.
Always use your personal seafaring experience when interpreting the
displayed values.
Safety Instructions concerning the installation
The system components should be installed by your shipyard or by a
specialist.
Use adequate working clothes if you install the system yourself. Avoid
loose clothing that may be caught by moving parts. Use a hair net if you
have long hair. Clothing and hair can be caught by moving or rotating
parts.
Remove all metallic or electrically conductive jewellery, such as chains,
bracelets, rings, etc. when working on the on-board electronics.
Disconnect the minus polarity at the battery before starting work to pre-
vent the risk of short-circuiting. Short-circuiting can cause cable harn-
ess fires, battery explosions and damage to other electronic systems.
Please note that all volatile electronic memories will lose their contents,
and will have to be re-programmed if you disconnect the battery. The
VDO instruments are not equipped with volatile memories.
Risk of explosion! Run the engine compartment blower for a certain time
before starting work in a gasoline engine compartment.
Check that there is enough space behind the instrument installation ope-
ning. Pre-drill the opening and complete the opening with a keyhole saw
(respect the safety instructions of the hand tool manufacturer).
When selecting the location for the sending unit check that no stringers
will be damaged and similary furniture, floor boards, cables, etc.
Solvent vapours can be produced by the sending unit sealant. Provide
sufficient ventilation. Respect the instructions of the sealant manufactu-
rer.
SAFETY

25
Use insulated tools if you must work without disconnecting the power
supply.
The electrical outputs of the Sumlog indicating instrument and the
connected cables must be protected against any direct contact or dama-
ge.
Capacitors in the unit can retain their charge, even if the unit is separa-
ted from its power supply.
The cables must have a sufficient insulation resistance or voltage rating,
and touching the contact points should be avoided.
Electrically conductive parts of the connected loads must also be protec-
ted against direct contact by adequate measures. The use of non-insula-
ted wires and contacts is strictly forbidden.
Safety Instructions concerning the maintenance
Repairs to the components of the sumlog system may only be made by
specialists authorized by VDO Kienzle. The system fulfills the applicable
safety regulations.
Capacitors in the unit can retain their charge, even when the unit is se-
parated from its power supply.
The Sumlog sending unit must be cleaned at regular intervals. Dirt pre-
vents or hinders the rotation of the paddle wheel, giving wrong or cau-
sing failure of the readings.
For longer periods of inactivity we recommend the removal of the sen-
ding unit from its hull sleeve.
Close the hull sleeve with the blind plug when removing the
sending unit to guarantee that it remains sealed. The floo-
ding valve integrated in the hull sleeve does not provide per-
manent protection against the entry of water.

The VDO Sumlog
The VDO Sumlog is an advanced speed measuring system, designed
for sport navigation.
The pointer displays the speed on an analog scale when the system is
active. The total distance or the trip distance travelled is shown by the
display in the lower dial section.
The indicating unit has a front pushbutton for the necessary basic set-
tings and for the selection of the displayed value. Using the instrument is
simple.
Up to two repeaters can be connected to the main instrument.

The functions of the VDO Sumlog
The analog indication shows the boat speed, while the display shows
either the total distance or the trip distance travelled, depending on the
selection, when the power is switched on.
The distance is selected by short activation of the pushbutton.
Example:
Indication of the total distance (2312.3 in this example)
or of the trip distance (12.96 in the example)
The units of the indicated speed and distance depend on the selected
calibration factor (see page 29).
The total distance is displayed from 0.0 to 99999.9 and the trip distance
from 0.0 to 999.99, thereafter the counter rolls over to zero again.
The trip distance is reset to zero by keeping the pushbutton pressed for
about 5 seconds when the trip distance is displayed.
Calibration of the VDO Sumlog
After installation of the system your VDO Sumlog must be calibrated to
obtain speed and distance measurements with the maximum accuracy.
Mark two distinct points on the map. The distance between these two
points defines the measuring length (see page 29). During the trip from
one point to the other, the VDO Sumlog measures the covered distance.
In flowing waters it is necessary to make the measuring run in both di-
rections to compensate for the influence of the current.
For indicating units with a simple graduation (12, 30 or 50 without unit in-
dication): Select the desired display unit (knots, mph or km/h) for your
operation prior to the measuring run.
Please note that it is not possible to switch to a different indicating unit
after calibration; this requires a new calibration.
For the indicating unit with twin graduations (50 kn/mph): Select nautical
miles as the unit for the measuring length.
FUNCTIONS / CALIBRATION
23I2.3

29
Make a measuring run at a cruising
speed, which remains as constant as
possible.
Check that the calibration factor is
C=1.00 (as supplied) at the beginning
of the measuring run, and that the trip
distance counter is set to zero.
The following example refers to a measuring run in water without a cur-
rent with a measuring length of 2 nautical miles (nm).
Approach starting point A of the measuring length.
Set the trip distance counter to zero (see page 28) when passing star-
ting point A.
Follow the measuring length on a straight line and note the indicated va-
lue (1.74 nm in this example) when passing end point B.
Calculate the calibration factor C with the following formula:
Effectively covered distance (A-B) 2.00 nm
C = --------------------------------------------------- = -------------- = 1.15
Indication of the display (A-B) 1.74 nm
Enter the calculated calibration factor C (1.15 in the example) as follows:
Keep pushbutton pressed and switch the indicating unit power supply
on. The display shows „CAL“.
Release the pushbutton. The current calibration factor is displayed (as
supplied: 1.00):

Press the pushbutton to increment up to the calculated calibration value.
Each press increments the value by 0.01. Incrementing is automatic if
you keep the pushbutton pressed.
The calibration factor setting range is from 0.50 to 2.50. On reaching
2.50 the counter rolls over to the calibration factor 0.50 again.
The set calibration factor is stored if the pushbutton is not activated for a
further 5 seconds. The display then automatically changes to display the
total distance.
The calibration factor also applies to the speed indication.
In the case of a measuring run in flowing water repeat the same distance
measuring steps in the opposite direction (measuring length C-D).
The calibration factor is calculated with the following formula:
Effectively covered distance (A-B) + (C-D)
C = ------------------------------------------------------------
Indication of the display (A-B) + (C-D)
Do not use the GPS navigator as a reference for VDO
Sumlog calibration. The GPS Navigator indicates speed
over ground (SOG), but the VDO Sumlog measures speed
through water.

- Check fuses in fuse box.
- No Sumlog function - Check free movement of
- Pointer stays at zero at speed paddle wheel,remove dirt de-
posits, replace paddle wheel
if necessary.
- Wrong indication - Check paddle wheel shaft for
wear, replace paddle wheel if
necessary.
- Paddle wheel direction not
optimised,check installation.
- Recalibrate unit.
Maintenance of the VDO Sumlog
The indicating unit is maintenance-free. Use a humid, lint-free or antista-
tic cloth for cleaning. Do not use cleaning detergents.
On the sending unit, check the paddle wheel and the paddle wheel shaft
for wear once per season. Both paddle wheel and paddle wheel shaft
must be replaced together if the clearance is excessive (see page 36).
Check the two O-rings on the sending unit and the two O-rings of the
blind plug for wear, brittleness or damage at regular intervals (twice per
season). Even the slightest wear requires O-ring replacement.

INSTALLATION
Installation of the VDO Sumlog system
Please read the safety instructions on pages 24 and 25 prior to
the installation.
Installation of the indicating unit
- Drill a hole, 86 mm dia., at an suitable location.
- Clean the material and remove any chips before inserting the indi-
cating instrument.
- Thread the indicating instrument cables from behind the moun-
ting hole through the housing mounting nut.
- Place the supplied black rubber ring on the instrument back.
- Make the electrical connections of the indicating unit per circuit
schematically (see „Electrical Installation“) and insert the
instrument into the installation hole.
- Secure the instrument by tightening the housing nut.
At d= 0.5 to 6.5 mm, installation A.
At d= 6.5 to 16.5 mm, installation B.
- The housing nut should only be tightened by hand.
Install the indicating instrument with studs and bracket (see
page 33) if you expect strong vibrations at the location whe-
re the instrument is to be installed (e.g. high-speed boats).

Installation of the sending unit
The sending unit must be installed in a turbulence-free zone in the hull. If
an echo sounder is installed, the Sumlog sending unit should be instal-
led at the same height and to the side of, or laterally offset to the echo-
sounder. Check for sufficient distance to stanchions, stringers,
bulkheads, etc. when drilling the hull.
Do not install the sending unit close to external valves, an-
odes, etc. to avoid influences by turbulence.
On sailing boats the sending unit should always be installed in front of
the keel, as close to the longitudinal ship axis as possible. On boats with
a long keel the installation should be at the end of the first third of the
hull, but not at the widest location of the hull.
On powerboats the sending unit should be installed at about the first
third of the hull and never towards the stern in a zone of strong turbu-
lence or up front, where strong disturbances by air induction must be

expected.
An ideal installation is near the longitudinal axis of the ship and in the
zone of the first stringer, directly in front of the engine compartment if
possible. At higher speeds this is the only location where a disturbance-
free operation can be expected.
Make a hole 39 mm dia., at a suitable location. The wall thickness can
be up to 30 mm. Camber the hole out at 45 degrees for good sealant
distribution during the assembly. To install the hull sleeve and the sen-
ding unit proceed as follows:
1. Put salt-water resistant sealant on the hull sleeve flange and intro-
duce the sleeve from the outside into the hole.
2. From the inside, install the black sealing ring on the hull sleeve,
then the white one, and screw the fixation nut down.
Lightly hand-tighten the fixation nut at first. After letting the sealant
harden, tighten the nut another ¼ turn by hand and check the hull
feedthrough for leaks.

3. Put the loop of the control rope around the hull sleeve and knot the
loose end of the rope to the blind plug.
4. Screw the flood valve to the hull sleeve until an audible click indi-
cates secure seating, is heard.
5. Insert the sending unit from the top and secure it with the nut.
Note the correct direction when inserting the sending
unit. The pointed side of the sending unit loop must be
directed towards the bow as soon as the sending unit
has been inserted.
Removal of the sending unit
Loosen the union nut and pull the sending unit from the sleeve by rota-
ting it slightly. Immediately insert the blind plug.
Never pull on the cable to remove the sending unit. Always
use the loop. Always insert the blind plug when the sending
unit has been removed.

INSTALLATION
Replacement of the paddle wheel
The paddle wheel of the sending unit is rota-
ted by the flow of water. The rotational
speed of the paddle wheel is measured
without contacts, and transmitted to the indi-
cating instrument.
Use a screwdriver to replace the paddle
wheel and its shaft.
Carefully lift the paddle wheel shaft upwards
to remove it from the sending unit.
Insert the new shaft into the new paddle
wheel and install shaft and wheel, again
using the screwdriver.
Check the correct installation direction when
replacing the paddle wheel. The spoon-sha-
ped leading surface of the wheel (A) must
be directed towards the pointed side of the
loop (S).
The pointed side of the loop must be direc-
ted to the bow when the sending unit is ins-
erted in the hull sleeve.
