Page 8: Chapter 1. Introduction
Chapter 1. Introduction The SECM70 is a full authority engine control module capable of withstanding the environment within the engine compartment and either on or off engine mounting. The 4 mounting feet on the controller are designed to accept specific rubber grommets and aluminum bushings to provide both vibration isolation as well as electrical isolation of the module case from chassis ground. -
Page 9: Chapter 2. Environmental Requirements
The SECM70 is designed for engine mount operation with the vibration isolators. If the SECM70 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 SECM70 product, causing premature failure of the module. -
Page 10: Temperature
Customers can verify the temperature in the desired mounting location by placing a thermocouple in the air near the operating SECM70. If the external ambient conditions are not worse case, this needs to be taken into consideration when measuring the SECM70 package temperature. If the measured air temperature when operating at worse case (fastest) engine speed and worse case (hottest) ambient conditions is less than 105 °C, the mounting location thermal stress is acceptable for the SECM70. -

Washer Grommet Bushing Figure 3-1: SECM70 Isolators The isolators must be inspected for wear at least once per year. For on-engine mounting, Woodward recommends replacing the vibration isolators once a year or sooner if wear is observed. -

Page 13: Orientation
SECM70 Digital Control Orientation The SECM70 has been validated for high pressure spray and steam cleaning, however it is not recommended to mount with the connector facing up or with the harness routed upward directly from the module (Figure 3-5). This orientation can allow moisture to run down the harness to the wire seals in the connectors. -
