Siemens Rwf40 - Manual

The RWF40 is engineered for flush panel mounting inside weather-protected control cabinets.

Use the or Down arrows to reach your desired temperature or pressure target. Press PGM to save the value. The display stops flashing. Entering Configuration Levels

If you are looking at the manual and see an option for "SSR" or a wiring diagram showing a connection to a "Solid State Relay," that is the solid feature. It is the controller's ability to precisely modulate power through a modern, non-wearing electronic switch.

Standard current (4-20mA) or voltage (0-10V) transmitter inputs. Control Outputs (Burner Actuator) Terminal Q1 (Common): Power feed for the actuator relays.

IP65 front protection when mounted in a panel cutout. 2. Mounting and Wiring Installation

Returns to the primary operational display loop. Up ( ) & Down (

Eliminates steady-state offset by integrating the error over time. 4. Self-Tuning Feature (Auto-Generation of PID Parameters)

Responds to the rate of change of the error. Prevents overshooting. 5. Self-Tuning (Auto-Tuning) Feature

Adjust numeric values or toggle through menu options. 6. Programming and Parameter Configuration

: Provides technical specifications and functional descriptions for OEM integration.

The RWF40 uses its display to communicate warnings and errors.

Relay outputs for burner control (open/close signals) or continuous analog outputs (0-10V or 4-20mA) for modulating actuators. Enclosure Rating: Front panel protected to IP65 standard. 🔌 Wiring and Terminal Connections
