Rev A MNL-6555.docx 8 of 18
3INSTALLATION
3.1 RECEIPT
Kobelt offers the 6555 control head in several configurations
(reference section 2.3). Upon receipt of the device ensure
that the model number and serial number are noted on the
table in page 2 of this manual. The serial number can be
found in the location noted at right. This model number will
determine what spare parts are applicable.
3.2 MECHANICAL
The control head must be mounted on a flat surface strong
and stiff enough to withstand the operating forces imposed during normal use without excessive flexing.
Choose a location that has sufficient room for the handle to swing to both extreme positions. Use the
template at the back of this manual to make the correct cut-out on the mounting surface.
The control head is equipped with (4) four clearance holes for #10 (M5) screws or bolts inserted from
underneath for direct mounting to the dash. Ensure the unit is securely fastened, preferably with an
anaerobic thread locker such as Loctite 243. Before securing the screws, ensure that the control head is
facing the correct direction by referencing the scales. This will ensure that the potentiometer output
increases towards the forward position.
3.3 ELECTRICAL
The standard control head has two 4 foot [1.0 m] long 3C/22AWG shielded cables for external
connections. Connect them to a 6505-2000, 6505-3000 or 6510 remote panel as required.
The potentiometers are wired as per the table below:

3.4 FUNCTIONAL TEST
After installation, test that the potentiometers provide minimum reading at full astern. Ensure that the
friction adjustment is adequate to hold the handle position at all angles. Adjust if necessary (reference
fig 1).
Do not put the vessel into service until the control
head has been tested. The Functional Test should be
carried out while the vessel is safely secured.
4MAINTENANCE
4.1 PREVENTATIVE MAINTENANCE
•Monthly
oLubricate the detent track (reference section 4.2)
•Quarterly (4 times per year)
oEnsure that the friction adjustment is adequate.
•Every 2 years
oInspect detent plate. Replace if necessary (reference section 4.3)
•Every 5 years
oReplace potentiometers
4.2 CALIBRATION
When replacing the potentiometer or if the
setting has become disturbed, follow these steps
to center the output:
1. Remove the control head from the
console
2. Locate the potentiometer in need of
centering.
3. Connect a multimeter to the Pot+ (white
wire) and the Pot Wiper (red wire). Set
the meter to read resistance.
4. Position the handle in the center (neutral)
position.
5. Loosen the two locking set screws on the pinion gear with a 1/16-inch Allen key.
6. Using a short flat head screwdriver, rotate the potentiometer shaft until the meter reads half of
the rated output (2500 ohms for a 5K potentiometer).
7. Compare the output between the wiper and Vref+ to wiper and Vref-. Adjust the shaft until the
two readings are equal.
Figure 2: Potentiometer centering

Rev A MNL-6555.docx 10 of 18
8. Tighten the two locking set screws and reinstall the control head.
4.3 LUBRICATION
The track the detent runs along on the cam must be lubricated to prevent premature wear. Use a
grease with MoS2 additives for best results. The following greases are approved:
Table 4: Approved Lubricants
EP Grease Brand
CHEVRON DELO MOLY 5% EP2
MOBIL XHP-322
SHELL S3 V460
4.4 RECOMMENDED SPARE PARTS AND KITS
The spare parts kept on hand will depend on the severity of the service. The User should monitor the
condition of their control head to predict necessary spare parts and ensure they are on hand when
needed. As a minimum Kobelt recommends keeping the following parts for each brake in service:
