Professional FAQ

How do I handle an I/O pack mismatch after replacement?
The module supports auto-reconfiguration; ensure the 'Auto-Reconfigure' setting is enabled in the ToolboxST Component Editor before powering up the new unit.

What is the purpose of the manual stroke testing mode?
Manual stroking allows engineers to isolate hydraulic issues by validating mechanical movement against electrical command signals without full system startup.

Is the front-facing infrared port used for field calibration?
No, the infrared port on the faceplate is not utilized; all configuration and diagnostics are performed via the Ethernet interface and ToolboxST software.

Selection Guide: How do I ensure compatibility with my TSVO terminal board?
Always cross-reference your TSVO hardware revision with the IS220PSVOH1B datasheet to ensure impedance matching for your specific servo valve type.

Why should I use the trend recorder during servo tuning?
The trend recorder captures high-speed response data that can reveal jitter or hydraulic lag, which are often invisible to standard diagnostic status indicators.
