Model: ESH044

Prerequisites

• Necessary hardware: 
  • EG4xxx or newer eGauge meter
  • Supported powered environmental sensors, EV1000 high voltage Sensor or eGauge compatible CTs
  • If powering away from the eGauge meter, a 5 Vdc power source is needed.

Important Installation Notes

• Power input: +5Vdc to the power terminal or 5V USB when using powered sensors (RJ-11 connections). Other voltages will cause damage.
• If extending CTs: do not install the Sensor Hub inside a distribution or breaker panel, only the CTs should be inside.
• CTid Sensor LEDs remain OFF unless temporarily activated through the CTid configuration page in the meter interface. This is expected behavior.
• If multiple Sensor hubs powered away from the eGauge are needed for an install, read: Powering multiple Sensor hubs for important installation considerations.

Instructions: 

Before beginning, check that you have all of the included parts: 

Assembling the Sensor Hub for use with powered CTid sensors:

If the Sensor Hub is located more than a few feet away from the eGauge, it should be powered by 5Vdc using the 2-pin port or an external USB power supply. For multiple Sensor Hubs powered from several sources please read: Powering multiple Sensor hubs for important installation considerations.

Step 1: Connect sensors to the appropriate ports on the Sensor Hub. Powered Sensors should connect to the RJ11 port, AC CTs should be connected to the green 2-pin port.  Refer to the Diagrams section under Additional Resources at the end of this article for example wiring diagrams.

Step 2: For each port used, move the selection switch to the left for a powered sensor or RJ11 connected DC CT or to the right for a standard 2-pin CT. Only one side of each port can be used at a time.

Step 3: When using powered sensors, the Sensor hub must be supplied with 5 Vdc. This can be supplied by either the included Mini-USB cable OR via the 2-pin 5 Vdc input. Do not use both inputs and do not supply more than 5 Vdc or damage to sensors may occur.

Step 4: If the distance between the eGauge and the Sensor hub is 1 foot or less, connect the included breakout cable to the RJ45 port of the sensor hub and connect the 2-pin plugs for each used port to available sensor ports on the eGauge. 

The breakout cable wiring is color coded to match the Sensor Hub port coloring to easily identify where each connected sensor plugs into the eGauge.

If the Sensor Hub is located farther away from the eGauge, a CAT5 cable wired to T568B may be added between the breakout cable and the Sensor Hub using the included Ethernet coupler.

Step 5: If using CTid sensors to read external signals such as the Pulse Sensor (EPS) or the 4-20 mA Sensor (EC420) refer to the sensor's product page for specific wiring information.

Step 6: Finally, configure the sensors that were connected. Please see this article for information regarding configuration of CTid enabled sensors.

Troubleshooting and Tips

• Issue: CTid is not detecting my sensor
  • Solution: Check that the selector switch for the port is in the correct position.
  • Solution: Check that the correct port is being scanned. Refer to the diagram in this article for breakout cable coloring for port identification.
     
• Issue: The light on the Sensor Hub is not lighting
  • Solution: Check that 5 Vdc is being applied to the Sensor Hub.
     
• Issue: The LED on my CTid sensor is constantly lit.
  • Solution: Has more than 5 V been applied to the sensor? Damage may have occurred.
