WARNING
Read this entire manual and all other publications pertaining to the work to be performed before in-
stalling, operating, or servicing this equipment. Practice all plant and safety instructions and precau-
tions. 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.

Table 1-1: Manual - overview
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 oper-
ation 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 enclosed in the configuration manual.

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 charg-
es 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 ar-
ea 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.

Installation
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
For installation into a panel door with the fastening clamps, please proceed as follows:
1.
Panel cutout
Cut out the panel according to the dimensions in the Panel Cutout chapter.
Note: It is not necessary to drill the holes if the fastening clamps are used.
2.
Remove terminals
Loosen the wire connection terminal screws on the back of the unit and
remove the wire connection terminal strip if required.
3.
Insert screws in clamps
Insert the four clamping screws into the clamp inserts from the shown
side (opposite of the nut insert) until they are almost flush. Do not com-
pletely insert the screws into the clamp inserts.
4.
Insert unit into cutout
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 (0.9 pound-force inches).
7.
Reattach terminals
Reattach the wire connection terminal strip (1) and secure them with the
side screws.

NOTE
Please note that the CAN bus must be terminated with a resistor, which corresponds to the impedance
of the cable (e.g. 120 Ohms, 1/4 W) at both ends. The termination resistor is connected between CAN-H
and CAN-L.

NOTE
Please note that the DTSC-200A cannot support a CAN Bus baud rate of 800kBits/s.
Possible CAN Bus Problems
If no data is transmitted on the CAN bus, check the following for common CAN bus communication problems:
•T structure bus is utilized
•CAN-L and CAN-H are switched
•Not all devices on the bus are using identical Baud rates
•Termination resistor(s) are missing
•The configured baud rate is too high for wiring length
•The CAN bus cable is co-routed with power cables
Woodward recommends the use of twisted-pair cables for the CAN bus (i.e.: Lappkabel Unitronic LIYCY (TP)
2×2×0.25, UNITRONIC-Bus LD 2×2×0.22).
Maximum CAN bus Length
The maximum length of the communication bus wiring is dependent on the configured Baud rate. Refer to Table
5-4 for the maximum bus length (Source: CANopen; Holger Zeltwanger (Hrsg.); 2001 VDE VERLAG GMBH,
Berlin und Offenbach; ISBN 3-8007-2448-0).

Table 5-4: Maximum CAN bus length
The maximum specified length for the communication bus wiring might not be achieved if poor quality wire is
utilized, there is high contact resistance, or other conditions exist. Reducing the baud rate may overcome these is-
sues.
