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.
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical,
or other operating limits may cause personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (i) constitute "misuse" and/or "negligence" within
the meaning of the product warranty thereby excluding warranty coverage for any resulting damage,
and (ii) invalidate product certifications or listings.
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.

Intended Use The unit must only be operated in the manner described by this manual. The prerequisite for a
proper and safe operation of the product is correct transportation, storage, and installation as well as careful op-
eration and maintenance.
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. Due to
the large variety of parameter settings, it is not possible to cover every combination. The manual is
therefore only a guide. In case of incorrect entries or a total loss of functions, the default settings may
be taken from the list of parameters in the configuration manual 37224 or from ToolKit and the respec-
tive *.SID file.

Chapter 2.
Electrostatic Discharge Awareness
All electronic equipment is static-sensitive, some components more than others. To protect these components
from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
1. Before doing 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 easily as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cigarette packages, cello-
phane wrappers, vinyl books or folders, plastic bottles, etc.) away from the control, modules, and 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 voltage-free (all connectors have to 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 or with
bare hands.
•When replacing a PCB, keep the new PCB in the plastic antistatic protective 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
antistatic protective bag.
CAUTION
To prevent damage to electronic components caused by improper handling, read and observe the pre-
cautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards, and Modules.
NOTE
The unit is capable to withstand an electrostatic powder coating process with a voltage of up to 85 kV
and a current of up to 40 µA.

Clamp Fastener Installation
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
For installation into a door panel with the fastening clamps, proceed as follows:
1. Panel cut-out
Cut out the panel according to the dimensions in Table 3-1.
Note:
Don't drill the holes if you want to use the clamp fasteners. If the holes
are drilled into the panel, the clamp fasteners cannot be used anymore!

2. Remove terminals
Loosen the wire connection terminal screws on the back of the unit and
remove the wire connection terminal strip if required (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 cutout. Verify that the unit fits correctly in
the cutout. If the panel cutout is not big enough, enlarge it accordingly.
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. (2) Raise the
clamp insert so that it is parallel to the control panel.

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 tighten-
ing torque of 0.1 Nm.

7. Reattach terminals
Reattach the wire connection terminal strip (1) and secure them with the
side screws.

Screw Kit Installation
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
NOTE
Don't drill the holes if you want to use the clamp fasteners. If the holes are drilled into the panel, the
clamp fasteners cannot be used anymore!
In order to enhance the protection to IP 66, it is possible to fasten the unit with a screw kit instead of the clamp
fastener hardware.
Proceed as follows to install the unit using the screw kit:
1. Cut out the panel and drill the holes according to the dimensions in Figure 3-4.
2. Insert the unit into the panel cutout. Verify that the unit fits correctly in the cutout. If the panel cutout is not
big enough, enlarge it accordingly.
3. Insert the screws and tighten to 0.6 Nm (5.3 pound inches) of torque. Tighten the screws with a crosswise
pattern to ensure even pressure distribution.
NOTE
If the thickness of the panel sheet exceeds 2.5 mm, be sure to use screws with a length of the panel
sheet thickness + 4 mm.

WARNING – Protective Earth
Protective Earth (PE) must be connected to the terminal 61 on the back of the unit to reduce the risk of
electric shock. This connection will be made using the screw-plug-terminal. The conductor providing
the connection must have a wire larger than or equal to 2.5 mm² (14 AWG). The connection must be
performed properly.

NOTE
Woodward recommends to use one of the following slow-acting protective devices in the supply line to
terminal 63:
• Fuse NEOZED D01 6A or equivalent
or
• Miniature Circuit Breaker 6A / Type C (for example: ABB type: S271C6 or equivalent)

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.

Voltage Measuring (FlexRange)
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
NOTE
DO NOT use both sets of voltage measuring inputs. The control unit will not measure voltage correctly
if the 100 V and 400 V inputs are utilized simultaneously.
NOTE
Woodward recommends protecting the voltage measuring inputs with slow-acting fuses rated for 2 to
6 A.

NOTE
The 100 V input terminals must used, if parameter 1800 (refer to Configuration Manual 37224) is config-
ured with a value between 50 and 130 V for proper measurement.
The 400 V input terminals must used, if parameter 1800 (refer to Configuration Manual 37224) is config-
ured with a value between 131 and 480 V for proper measurement.
