Functional Description

9905-708 is a Digital Synchronizer and Load Control Module developed by Woodward. The module is specifically designed for digital synchronization and load control applications, enabling seamless integration into systems. It plays a vital role in synchronizing multiple generators and aligning their frequencies and voltages before connecting them to the grid. This synchronization process ensures a smooth and stable transfer of power, minimizing disturbances and potential damage to the connected equipment.

Features

• With its digital architecture, the module provides enhanced accuracy and reliability compared to traditional analog synchronizers. It utilizes advanced algorithms and precise measurement techniques to achieve accurate frequency and voltage matching between generators.
• The module offers a user-friendly interface for easy configuration and monitoring. Operators can access a comprehensive set of parameters and settings, allowing them to customize the synchronization and load control process according to specific application requirements. The module also provides real-time information and diagnostics, enabling operators to monitor the system's status, identify potential issues, and take proactive measures to maintain optimal performance.
• If you encounter resistance while installing a module, do not force it. Check the connectors for bent contacts or foreign objects after removing the module. Check that the module screws are completely retracted. Forcing a module into place may cause the connector to break or the securing screws to bend.

Unit Location

• Ensure that the MicroNet unit(s) are installed in a dry location, away from water and condensation.
• Check that the ambient temperature of the system location is not below 0 �C (32 �F) or above 55 �C (131 �F), and that the relative humidity is not greater than 90%, non-condensing.
• Provide adequate ventilation to allow the units to cool. Shield the units from heat if they must be mounted near heat-producing devices.
• A 3" (8 cm) air gap above and below the chassis is recommended for proper airflow.
• To ensure EMC compliance, all chassis mounting screws (#8-32 M4) must be installed to properly ground the chassis to the mounting plate.
• Install the units and their connecting wires away from high-voltage/high-current devices and inductive devices. Shield both the system connecting wires and the interfering devices or wires if this is not possible.
• Provide a conductor to a good earth ground if the chosen location does not already have one.
• This equipment is only appropriate for Class I, Division 2 Groups A, B, C, and D or non-hazardous locations. The 24/12 and 16 channel relay modules are only for use in non-hazardous locations.
