E-5D: Sensors connected to RJ45 sensor ports stop working

E-5D: Sensors connected to RJ45 sensor ports stop working

Issue: Sensors connected to RJ45 sensor ports stop working.

Cause: Sensors applied collectively exceed current rating of row (ports 1-5). Fuse protecting ports has opened.

Solution: Disconnect sensors. Power cycle the unit. Reconnect the sensors, ensuring that the load of all 5 sensors per row does not exceed 500mA (i.e. only one keypad). Alternatively, avoid powering down the unit by waiting 10 minutes after disconnecting the sensor to reset the internal fuse.
