⚙️ Parameter Configuration and Modification Methods

Configuring and calibrating parameters for the IS200TSVCH1AJE terminal board is executed using the GE ToolboxST application software via an engineering workstation.

💻 Connection Setup: Connect the programming workstation to the Mark VIe controller network to establish an online communication link.
📂 Software Navigation: Open ToolboxST, browse the hardware configuration tree, and select the servo control module associated with the TSVC terminal board.
🛠️ Parameter Adjustment: Modify valve calibration constants, null bias currents, feedback scaling factors, and fault trip thresholds to match the specific hydraulic actuator requirements.
📥 Download & Verify: Compile the updated configuration database and download it to the controller. Perform an online valve calibration routine and check diagnostic logs to ensure proper response.

🔄 Manual / Automatic Mode Switching

Operational control modes for servo-driven hydraulic valves are managed seamlessly through the Mark VIe control architecture.

⚙️ Automatic Mode: The controller actively positions the servo valve using closed-loop control algorithms, comparing real-time LVDT feedback against demand references to regulate fuel or steam flow automatically.
🛠️ Manual Mode / Open-Loop Control: Maintenance or commissioning engineers can enable manual control or output forcing via authorized software tools to stroke valves independently for testing.
🔒 Switching Procedure: Transitioning between modes requires proper security credentials and safety interlocks to prevent sudden hydraulic shifts or process upsets.
