Electrostatic Discharge Awareness
Electrostatic
Precautions
Electronic controls contain static-sensitive parts. Observe the
following precautions to prevent damage 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.
To prevent damage to electronic components caused by improper
handling, read and observe the precautions in Woodward manual
82715 , Guide for Handling and Protection of Electronic Controls,
Printed Circuit Boards, and Modules.
Follow these precautions when working with or near the control.
1. 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 charges as much as synthetics.
2. 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:
Do not touch any part of the PCB except the edges.
Do not touch the electrical conductors, the connectors, or the components with conductive
devices or with your 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.

Some degraded performance can occur on RTD and thermocouple
inputs in the presence of radiated energy from transmitters such as
cell phones. This degraded performance is in the form of a slight
change in the accuracy of the measured temperature. It is
recommended that operation of such devices be kept more than 3 m
from the AtlasSC control. This will prevent any degradation.
Installation of the unit in a metal enclosure will also prevent
degradation.

General Information
Introduction
This manual describes the Woodward AtlasSC™ Digital Control. It provides a variety of useful information
for the user ranging from simple basic descriptions to detailed information on wiring, specifications,
programming, and functionality. Included are:
General information on the AtlasSC platform and available versions
A physical description of the control hardware
A description of all AtlasSC modules
A listing of accessories that may be used with the platform
Information on AtlasSC programming, distributed I/O (input/output), and control communications
Installation and maintenance
Troubleshooting information
AtlasSC Control Description
The AtlasSC digital control platform fits a wide range of prime mover applications. These include small
mechanical-drive units with a minimum of complexity on up to small two-shaft gas turbine generator sets
that require unit sequencing and load control. The AtlasSC control is programmed to the specific needs of
the prime mover and its driven load.
At the heart of the AtlasSC control is a 32-bit microprocessor that runs a powerful Real Time Operating
System. This operating system is specifically designed to control the proper timing of all application code
so that dynamic performance of the final control system is absolutely guaranteed. Each piece of the
application code is “scheduled” under a Rate Group structure that ensures execution of the code at a
predetermined time.
Application programming is accomplished via Woodward’s GAP™ Graphical Application Program. GAP is
a pictures-to-code system that provides a high-level programming environment for users who have control
expertise but do not have specific programming skills. Once the application program has been generated
and loaded into the AtlasSC control, the user can view variables and tune the control with the Woodward
Watch Window Standard service tool. Connection to other devices, such as an HMI, is accomplished by
means of serial Modbus®* ports on the control, and the desired information flow is programmed into the
control via GAP. Another serial Modbus port can be used to connect distributed I/O if required.
*—Modbus is a trademark of Schneider Automation Inc.
The hardware platform is based on the industry-standard PC/104 bus structure. In the AtlasSC control,
the backplane is the SmartCore board. The PC/104 modules are “stacked” onto the SmartCore board in
order to add I/O or other functionality. Each of the stacked modules has an on-board DIP switch that is
positioned to the unique address of that particular module. The AtlasSC control uses a second stack
called the Power Bus Stack. This stack is used primarily for power-related I/O. Three serial Modbus
communications ports are available for a variety of uses. The control runs on low-voltage dc power (18–
32 Vdc). AtlasSC field wiring is accomplished via terminal blocks that plug into the control modules.
Control Versions
The AtlasSC control versions are differentiated by anticipated application categories. As such, the I/O
content will vary, and one or more of the optional I/O modules may be required. Table 1-1 shows the
configuration of the modules for the AtlasSC part numbers that are available.

Figure 1-1 shows diagrammatically the physical arrangement of the modules in the AtlasSC hardware.
The hardware uses two stacked-bus arrangements to provide the required structure. The Power Bus
Stack is used for the power-related I/O as well as the discrete output drivers. The PC/104 Stack is used
primarily for the signal I/O. Depending on the part number specified, the AtlasSC control may or may not
have an Analog Combo board or a PowerSense board (refer to Table 1-1 above). The stack arrangement
shown in Figure 1-1 is for the maximum configuration (8273-043).

Control Accessories
The AtlasSC digital control is designed to interface with the Woodward Watch Window Standard and
Watch Window Professional service tools. Watch Window is a configuration and troubleshooting tool that
provides a window into the control system. It runs on a PC and is connected to a serial communication
port on the AtlasSC control. Watch Window is available from the Woodward website
(www.woodward.com/ic) or from a CD-ROM that can be purchased.
Watch Window Standard performs three primary functions:
Initial Control Configuration
Configures the AtlasSC control to specific application or site requirements.
Monitoring and Tuning
Allows the user to view system variables and tune the application software for desired performance.
Management of Configuration and Setpoints
Allows the user to upload or download all tuning and configuration variables to or from the AtlasSC
control.
Watch Window Professional provides all of the functions of Watch Window Standard, plus it provides the
tools to download application code into the AtlasSC hardware.

Installation
Introduction
This chapter provides the general information for mounting location selection, installation, and wiring of
the AtlasSC™ control. Hardware dimensions, ratings, and requirements are given for mounting and wiring
the control in a specific application.
General Installation
When selecting a location for mounting the AtlasSC control, consider the following:
Protect the unit from direct exposure to water or to a condensation-prone environment.
The operating range of the AtlasSC control is –20 to +70 °C
(–4 to +158 °F).
Provide adequate ventilation for cooling. Shield the unit from radiant heat sources.
Do not install near high-voltage or high-current devices.
Allow adequate space around the unit for servicing and wiring.
Do not install where objects can be dropped on the terminals.
Ground the chassis for proper safety and shielding.
When installing on a generator set package, provide vibration isolation.
Shipping Carton
Before unpacking the control, refer to the inside front cover and page vi of this manual for WARNINGS
and NOTICES. Be careful when unpacking the control. Check for signs of damage such as bent or
dented panels, scratches, loose or broken parts. If any damage is found, immediately notify the shipper.
The AtlasSC control was shipped from the factory in an anti-static foam lined carton. This carton should
always be used for transport of the control when it is not installed.
Mounting
Figure 1-2 shows the AtlasSC control layout and mounting pattern. The AtlasSC digital control is to be
mounted in an appropriate enclosure for the installed environment. This equipment is designed for
installation within a control room panel or cabinet.
The standard AtlasSC package must be mounted to allow sufficient room for wiring access. Eight front
panel mounting holes permit secure mounting. Depending on its configuration, the AtlasSC weighs
between 3.4 and 4.5 kg (7.5 and 10 pounds), and has an operating range of –20 to +70 °C ambient air
temperature. A minimum of 25 mm (1 inch) of clear space around the outer surfaces of the AtlasSC is
adequate for ventilation, however approximately 75 mm (3 inches) of space may be required for wiring,
depending on wire size.
Environmental Specifications
Operating Temperature
The AtlasSC Control Platform operates in a specified ambient temperature of
–20 to +70 °C (–4 to +158 °F).
Continuous operation with insufficient airflow or higher operating
temperatures will lead to reduced reliability and possible damage to
the control.

Storage Temperature
The AtlasSC Control Platform is designed to be stored without applied power at the temperature range of
–40 to +105 °C (–40 to +221 °F).
Shock
The AtlasSC Control Platform was designed to meet the shock requirements specified by MIL-STD-810C
procedure 516.2, procedure 1 (30 Gs, 11 millisecond half sine pulse). During Shock, relay bounce shall
be limited to less than 100 ms.
Vibration (Random)
SAE J1455 (10–2000 Hz @ 0.04 G²/Hz, 8.2 Grms PSD)
Vibration (Sine)
Lloyds Register Test Specification No. 1 Vibration Test 1 (5–13.2 Hz, ±1 mm; 13.2–100 Hz, 0.7 g)
Audible Noise Emission
The AtlasSC Control Platform does not emit an audible noise above 70 dBA as measured 1 meter away,
with or without a fan.
Electrical Connections
Most inputs and outputs to the AtlasSC control are made through “CageClamp” terminal blocks.
For noise suppression, it is recommend that all low-current wires be separated from all high-
current wire.
The pluggable terminal blocks on the I/O modules are screwless CageClamp style blocks. The spring
clamp can be actuated by using a standard 2.5 mm (3/32 inch) flat bladed screwdriver (see Figure 2-1).
The AtlasSC pluggable terminal blocks accept wires from 0.08–1.1 mm² (28–18 AWG). Two 0.5 mm² (20
AWG) wires or three 0.3 mm² (22 AWG) wires can be easily installed in each terminal. Wires for the
pluggable I/O terminals should be stripped 8 mm (0.3 inch).
Most of the AtlasSC control’s terminal blocks are designed to be removed by hand. After AtlasSC input
power is disconnected, the terminal blocks can be removed one at a time by pulling them straight out. Be
careful not to pull the plug out at an angle, as this will fracture the end terminal.
Method #1
Free Hand (holds spring open)
Method #2
Bench (momentarily opens spring
while force is applied)
Figure 2-1. Spring Clamp
The AtlasSC fixed terminal blocks used for the power supply input accept wires from 0.08–1.1 mm² (28–
18 AWG). Two 0.5 mm² (20 AWG) wires or three 0.3 mm² (22 AWG) wires can be easily installed in each
terminal. Wires for the fixed mounted power terminals should be stripped 5 mm (0.2 inch).
