Communication
LEDs
There are two pairs of LEDs that indicate communication status for the
Rosemount 2240S Multi-input Temperature Transmitter:
• when a Water Level Sensor (WLS) is connected, two LED signals
indicate that measurement and status information is communicated
over the Sensor bus to the 2240S
• two LEDs indicate that the 2240S communicates over the Tankbus with
a Rosemount 2410 Tank Hub
