Page 9: Chapter 1. General Information
The SECM112 is designed for engine mount operation with the vibration isolators. If the SECM112 is mounted on a bracket not provided by Woodward, the bracket needs to be evaluated in the application. It is possible for a bracket resonance to be incompatible with the SECM112 product, causing premature failure of the module. -
Page 10: Figure 1-1. Location Of Accelerometer To Measure Mounting Vibration
Customers can verify the temperature in the desired mounting location by placing a thermocouple in the air near the operating SECM112. If the external ambient conditions are not worst-case, this needs to be taken into consideration when measuring the SECM112 package temperature. If the measured air temperature when operating at worst-case (fastest) engine speed and worst-case (hottest) ambient conditions is less than 105 °C, the mounting location thermal stress is acceptable for the SECM112. -
Page 11: Secm112 Installation
SECM112 Installation Isolators The SECM112 has 4 mounting feet and Figure 2-1 illustrates the isolator assembly pre-assembled on the module. All variants of the module come from the factory with the grommet and bushing pre-installed. Washers must be used and are provided by Woodward (default) or the user (upon request). -

Page 13: Figure 2-3. Preferred Secm112 Mounting Orientations
SECM112 Digital Control Orientation The SECM112 connector is rated for high pressure spray to IP6K9K; however, it is not recommended to mount with the connector facing up or with the harness routed upward directly from the module. This orientation can allow moisture to run down the harness to the wire seals in the connectors. The module must be mounted with the heat fins facing outwards to maximize airflow over the fins. -

Figure 2-6. Harness Clearance Connector Information The SECM112 mating connectors, terminals, wire cap (backshells), and wire plug part numbers are listed in Table 2-1 below. Note that the center grey connector has the opposite orientation to the others. All unused pins must be plugged with the proper wire plugs to maintain environmental integrity.
