9240si Loop Controller User Manual (2024)

Cause: The input sensor circuit is open, or a thermocouple wire is severed.

Displays the target Setpoint Value or parameter set values. LED Status Indicators: OUT1 : Flashes when the primary control output is active. ALM1 : Illuminates when the Alarm 1 threshold is breached. AT : Flashes continuously during the PID auto-tuning cycle. Key Operations

: Rotate or toggle the mode selector interface to CONTINUITY . Press the start button. Read the digital metric value on the display. Values exceeding the maximum airframe threshold (typically above

By referring to this user manual and appendices, users can maximize the capabilities of the 9240SI loop controller and achieve optimal performance in their industrial processes.

Top red LED display shows current sensor readings.

Understanding the hardware limits ensures safe and accurate operation. 100–240 VAC, 50/60 Hz, or 24 VDC optional. Power Consumption: 15 VA maximum.

The your system uses (Relay, SSR, or 4-20mA).

To get stable control without manual tuning, use the built-in auto-tuning function. ALM1 : Illuminates when the Alarm 1 threshold is breached

Connect the AC/DC power supply to the designated terminals. Always use a fuse or circuit breaker.

Understanding the hardware limits and electrical capabilities of the 9240si ensures a safe installation and reliable long-term operation. Environmental and Electrical Limits

Sensor loop is broken or disconnected. Check the thermocouple or RTD wiring for loose terminals or fractured wires.
