WARNING
Read this entire manual and all other publications pertaining to the work to be performed before install-
ing, operating, or servicing this equipment. Practice all plant and safety instructions and precautions.
Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown device(s), that operates totally independently of the
prime mover control device(s) to protect against runaway or damage to the engine, turbine, or other
type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gov-
ernor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s),
or the controlled device(s) fail.
CAUTION
To prevent damage to a control system that uses an alternator or battery-charging device, make sure
the charging device is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
•Discharge body static before handling the control (with power to the control turned off, contact a
grounded surface and maintain contact while handling the control).
•Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards.
•Do not touch the components or conductors on a printed circuit board with your hands or with
conductive devices.

NOTE
This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions,
configuration screens and other details described, which do not exist on your unit may be ignored.
The present manual has been prepared to enable the installation and commissioning of the unit. Be-
cause of the large variety of parameter settings, it is not possible to cover every possible combination.
The manual is therefore only a guide. In case of incorrect entries or a total loss of functions, the default
settings can be taken from the enclosed list of parameters.

Electrostatic Discharge Awareness
All electronic equipment is static-sensitive, some components more than others. To protect these components
from static damage, you must tak ectrostatic discharges.
Follow these precautions when
Before performing maintenance on the electronic control, discharge the static electricity on your body to
ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.).
2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials.
Wear cotton or cotton-blend materials as much as possible because these do not store static electric char-
ges as much as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette
packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from
the control, the modules, and the work area as much as possible.
4. Opening the control cover may void the unit warranty.
Do not remove the Printed Circuit Board (PCB) from the control cabinet unless absolutely necessary. If
you must remove the PCB from the control cabinet, follow these precautions:
•Ensure that the device is completely de-energized (all connectors must be disconnected).
•Do not touch any part of the PCB except the edges.
•Do not touch the electrical conductors, connectors, or components with conductive devices with your
hands.
•When replacing a PCB, keep the new PCB in the protective antistatic bag it comes in until you are
ready to install it. Immediately after removing the old PCB from the control cabinet, place it in the
protective antistatic bag.
e special precautions to minimize or eliminate el
working with or near the control.

For installation into a door panel, proceed as follows:
1. Panel cut-out
Cut out the panel according to the dimensions in Figure 4-1.
Installation
2. Remove terminals
Loosen the wire connection terminal screws on the back of the unit and
remove the wire connection terminal strips if required (1).
1
3. Loosen clamping screws
Loosen the four clamping screws (1) until they are almost flush with the
clamp inserts and tilt the clamp inserts down by 45° (2) to remove them
from the housing. Do not completely remove the screws from the clamp
inserts.
12
4. Insert unit into cut-out
Insert the unit into the panel cut-out. Verify that the unit fits correctly in
the cut-out. If the panel cut-out is not big enough, enlarge it accord-
ingly. Ensure that the gasket is placed properly if used.
5. Attach clamp inserts
Re-install the clamp inserts by tilting the insert to a 45° angle (1). Insert
the nose of the insert into the slot on the side of the housing. Raise the
clamp insert so that it is parallel to the control panel (2).

2
6. Tighten clamping screws
Tighten the clamping screws (1) until the control unit is secured to the
control panel (2). Over tightening of these screws may result in the
clamp inserts or the housing breaking. Do not exceed the recommended
tightening torque of 0.1 Nm.

2
7. Reattach terminals
Reattach the wire connection terminal strips (1) and secure them with
the side screws.
1
Note: If the gasket is damaged, it needs to be replaced. Use only the original gasket kit (P/N 3050-1057) for re-
placement.

CAUTION
Terminal 3 must be used for charging voltages exceeding 16 Volts. Connecting the terminals 3 and 4
incorrectly, may result in damage to the unit.
NOTE
The charging alternator D+ acts as an output for pre-exciting the charging alternator during engine
start-up only. During regular operation, it acts as an input for monitoring the charging voltage. Refer to
Firing Speed Detectionon page 56 for more information.
