Most single-loop PID controllers share common setup steps. If you can find any manual for a similar-looking controller (same number of buttons, display digits, I/O terminals), the configuration will likely be 80–90% the same. 9240si loop controller user manual

Typical programming flow:

The 9240SI Loop Controller is a programmable, single-loop PID controller for process control applications. It accepts a standard analog process input, provides PID control with auto-tuning, and offers configurable alarm outputs and a compact panel-mount package suitable for industrial environments. Most single-loop PID controllers share common setup steps
