Sensor Wiring

Overview

Connect the correct sensor leads to the main board according to the lead locations labeled directly on the

main board.

Rosemount Analytical SMART pH sensors can be connected to the 1066 using either the integrated cable

SMART sensor or a compatible VP8 pH cable.

After completing the wiring of the sensor leads, carefully route the excess sensor cable through the cable

gland.

Separate the sensor and output signal wiring from the loop power wiring. Do not place the sensor and

power wires in the same conduit or near a cable bridge.

Sensor Wiring Details

Sensor wiring should be done in the order shown above.

If the solution ground terminal is left open without doing so, a high reference impedance fault alarm will

continue to sound.

TB4 Preamplifier Power: The power wire from the pH sensor or preamplifier in the junction box is

connected to this terminal to supply power to the preamplifier.

TB1 pH Electrode Input: The pH electrode lead and its shield are located on this terminal as shown.

Smart pH Sensor: The smart pH sensor has a ground wire (not to be confused with the solution ground

wire)

that should be connected to the enclosure ground as shown in the power wiring diagram

Applications 

The SECM70 control platform is suitable for a variety of applications including gasoline and

natural gas engines for power generation, forklifts, forklifts, and on-highway vehicles.

The SECM70 control system is programmed to meet the specific needs of prime movers and the loads they drive.

At the heart of the SECM70 control system is a powerful 32-bit ST SPC563M64 microprocessor running Woodward’s ControlCore operating system.

Application programming is done through Woodward’s MotoHawk application software tool.

MotoHawk is a rapid control system development tool that allows control engineers to quickly create

control software directly in Simulink diagrams and run it on any MotoHawk enabled electronic control module.

Working directly in the Simulink environment, application developers can turn application models into files

that can be programmed directly into Woodward production hardware in a single build step.

MotoHawk provides an advanced programming environment for users with control system expertise

but not necessarily specific embedded programming skills.

Once the application is generated and loaded into the SECM70 controller via the CAN port,

users can view variables and adjust controls using appropriate service interface tools such as Woodward’s ToolKit or MotoTune.

Connectivity to other devices, such as diagnostic tools, can be accomplished through additional CAN ports on the controller.

The required information flow can be programmed into the controller via MotoTune or ToolKit.

The SECM70 controller consists of a rigid printed circuit board that is attached to an aluminum housing with thermal adhesive.

It is then closed and sealed with an aluminum cover. Connection to the controller is made through

a single 70-pin automotive style sealed connector.

The controller can be mounted directly to the engine or frame using vibration isolators pre-installed on the controller or supplied separately.

Outputs:

8 electronic spark triggers for smart ignition coils

9 low-side drivers, 3 lamp drivers

1 main power relay driver to power engine electrical components

2 H-bridge drivers for electric throttle and actuator

1 sensor power (5 V) output

Communication:

2 CAN 2.0b channels

Features and Functionality

Application programming is done on the PCM112 using Woodward’s MotoHawk application software tool.

MotoHawk is a rapid control system development tool that allows control engineers to quickly create control software directly in Simulink diagrams.

The software runs on any electronic control module that supports MotoHawk.

Working directly in the Simulink environment, application developers can convert application models

into files that can be programmed directly into Woodward production hardware in a single build step.

MotoHawk provides an advanced programming environment for users with control system expertise

but not necessarily specific embedded programming skills.

Once an application has been generated and loaded into the PCM112 controller via the CAN port, the

users can view variables and tune the controller using appropriate service interface tools such as Woodward’s ToolKit or MotoTune.

Connections to other devices (such as diagnostic tools) are accomplished through other CAN ports available on the controller.

The required information flow is programmed into the controller via MotoTune or ToolKit.

The PCM112 controller consists of a rigid printed circuit board that is attached to an aluminum enclosure

using thermally conductive adhesive and then closed and sealed with an aluminum cover.

Connections to the controller are made via three automotive style sealed connectors.

The controller can be mounted directly to the engine or frame using vibration isolators.

The 8923-2241 includes the 1751-6685 module and mounting kit.

Woodward also offers a suite of software service-tools to

simplify system troubleshooting and service. These tools

provide high-speed (5 milliseconds) operational and

analytical information such as graphical display of operating

data, historical trending, event logging, X-Y plotting, system

overviews, calibration pages, and other functions.

Expandability

The MicroNet TMR platform is expandable into additional expansion chassis as required by the system size, and will

support any mix of I/O, including networked and/or distributed I/O. Redundant “Real-Time Ethernet” networks are

utilized between main and expansion chassis to ensure a fast and reliable communications. Expansion chassis are

available in 6-, 8-, 12-, or 14-slot models. This TMR architecture allows all remote I/O points to be automatically

shared with each kernel CPU, increasing system robustness and availability.

Communications

The MicroNet TMR platform’s open-architecture allows

users to easily interface with plant DCSs, HMIs, and

distributed I/O devices for system operation, as well as

control programming and service. Multiple

communication ports and protocols are available for

system communications, allowing users to select their

desired communication method and level of

communication redundancy. MicroNet-to-DCS
