Connect the compensated wire to Terminal 13, and the remaining identical wires to Terminals 14 and 15.
Connect the single-colored wire to Terminal 13. Connect the two identical-colored wires to Terminals 14 and 15.
— Look for a full nameplate: manufacturer, model, serial, power rating. Any logo or FCC ID? Search that exact text.
The P/N 9240SI model has been discontinued. ECA GROUP has replaced it with P/N 20549SI, a new loop controller that is fully backward compatible and offers enhanced features. 9240si loop controller user manual
Always disconnect the main power source before performing any wiring operations to prevent electrical shock.
Typical programming flow:
Sets the deadband value to prevent alarm chattering when the process variable hovers near the threshold. 6. Loop Tuning and Optimization Connect the compensated wire to Terminal 13, and
As Jack pored over the manual, he stumbled upon a section on "PID tuning." It explained that the 9240si used a Proportional-Integral-Derivative (PID) algorithm to adjust the process variables. Jack realized that the unstable readings were likely due to incorrect PID settings.
The default view displaying the Process Value (PV) on the top screen and the Setpoint Value (SV) on the bottom screen.
Avoid areas with high mechanical vibration or strong electromagnetic fields (EMI). 3. Wiring and Electrical Connections — Look for a full nameplate: manufacturer, model,
The easiest way to configure PID parameters is via the built-in Autotune feature:
Since it’s not readily online, try these practical steps:
A formalized troubleshooting sequence from an A320 TSM demonstrates its practical use:
