Manual Analog Override Switch
Initial installation or trouble shooting can be smoother and much less costly by adding the RIBMNA1D0. It
allows you to manually control an analog output without accessing complicated algorithms in a controller.
An indicator is provided for visual confirmation of percentage output. When you are finished, you can switch
back to auto to put the controller back in control.

Self-Calibrating Current Sensors
The self-calibrating current sensor begins its 30 second self calibration process the first time current is applied within
the operating range. This procedure uses the user selected differential to set the trip threshold at a 15% or 25% level.
Selection is completed prior to install using the appropriate DIP switch setting, keeping the installer’s hands away from
possible shock hazard, as well as saving installation time.

Echelon® Thermistor-In Application
24
A thermistor is used to read the temperature of a room or area. That data is fed back to the LonWorks® system. When
the temperature is out of range, the relay is commanded by the network, activating the exhaust fan, heater, or other
device. A current sensor is used to feed back load status to the network. If there is a command and status mismatch,
the network can issue an alarm to the operator’s console.
