: Document the values exactly as shown on the screen onto your regulatory maintenance tracking release sheets. Calibration, Quality Assurance, and Field Troubleshooting Required Calibration Intervals 9240si loop controller user manual
Connect the positive lead to the positive terminal and the negative lead to the negative terminal. Use the correct compensation wire extension.
High-visibility dual LED display (Process Value and Setpoint). Leave at least 20mm of clearance around the
Once completed, the LED turns off. The new Pb , ti , and td constants save automatically to the non-volatile memory.
Adjusts numerical values or changes selections within a sub-menu. Input Capabilities The 9240si features universal input slots
used to measure and verify the integrity of fire detection loops on various aircraft models, including those from Bombardier Micro Precision Calibration Core Measurement Features Continuity Mode : Measures sensitive core continuity from 1 to 99 with a precision of 1% of the full scale. Insulation Mode
The controller will force the system through a series of controlled oscillations to measure the process lag and thermal inertia. Once complete, it calculates and stores the optimal Pb (Proportional Band), ti (Integral Time), and td (Derivative Time) values. Manual PID Tuning Adjustments
