IP65 / NEMA 4X front panel protection against dust and water jets. Input Capabilities The 9240si features universal input slots that support: Thermocouples: Types J, K, T, E, R, S, B, and N. RTDs: Pt100, Ni120 (2-wire or 3-wire configurations). Linear DC: 0–20mA, 4–20mA, 0–5V, 1–5V, and 0–10V. 2. Installation and Mounting
Connect line voltage to Terminals 1 (Line/Live) and 2 (Neutral). Connect ground to the dedicated chassis terminal if provided. Sensor Input:
Set to rEV (Reverse) for heating applications (output decreases as temperature increases). Set to dir (Direct) for cooling applications.
Displays the target Setpoint Value or parameter codes in green digits. LED Status Indicators: OUT1 / OUT2: Illuminates when control outputs are active.
Store in a cool, dry place within the provided protective case. 4. Where to Find the Official 9240SI Manual
Internal EEPROM error. The unit has suffered a memory write failure. Cycle the main power. If the code persists, factory defaults must be reloaded via the Engineering Menu. Preventative Maintenance Checklist
When an internal diagnostic check or system hardware monitoring loop fails, the upper display flashes an error code. Error Code Potential Root Cause Recommended Corrective Action oPEn Sensor break or disconnected loop input. Check input wiring; replace damaged thermocouple or RTD. HHHH Input value exceeds high limits (Over-range).
