Page 7: Sensor Connections
To ensure intrinsic safety is maintained it is required that the installer follow these guidelines when connecting sensors to the SignalFire node. See pictures for proper wire routing examples. Strip the wires so that there is minimal exposed un-insulated wire when inserted into the screw terminal. - Page 8 Optionally a “Level Cutoff” setting can be set for the product and/or level readings. Any reading at or below the configured cutoff setting will be reported as zero. This is useful as the float cannot reach the actual bottom of the tank due to the weight and required spacing.
