Fluksometer
We will in turn introduce the Fluksometer v3’s ports, button and LEDs. The
Fluksometer v3 is currently available in a single ‘E’ version, a.k.a. FLM03E.
ports
- sensor ports
The screw terminal contains fourteen inputs. A port on the screw terminal
is defined as a pair of adjacent inputs. The port numbers are printed on the
front of the enclosure for easy reference, with the polarity denoted by +
and -.
Ports #1 to #3 are current clamp ports that are tuned to accept Flukso
FLS06-type split-core current clamps. Ports #4, #5 and #6 can be used for
counting pulses. This includes support for the S0 interface (S0 is an open-
collector interface standardized in DIN EN 62053-31) common to DIN-rail
energy meters. Pulse ports accept Flukso water and gas probes as well. Port
#7 can be hooked up to a NTA8130-compliant local P1 port found on Dutch
smart meters. Contrary to the other ports, port #7 has its polarity
indicated by the letters a (tx) and b (rx).
Note
The current FLM03E firmware still lacks the P1 port decoder. This
functionality will be added in a future release.
- ethernet
- Both ethernet ports support a 10baseT/100baseTx interface with auto-
negotiation and auto MDI/MDI-X crossover detection. The right ethernet port
(LAN) is meant for configuring the Fluksometer, while the left port (WAN)
can be used as an internet uplink for the Fluksometer.
- power port
- While the power port can still accepts a 9-15V DC voltage, we now ship all
Fluksometer v3’s with a 9V AC-AC adapter. The AC adapter acts as a power
source to the FLM03 as well as the line voltage sensor.
- USB
- The USB 2.0 type A port on the right side of the Fluksometer can accept a 3G
stick. This allows the FLM to make a direct internet connection, bypassing
the LAN.
LEDs
The Fluksometer has six red LEDs on the top of its enclosure. Together these
LEDs provide an overview of the Fluksometer’s internal functioning, the status
of its network interfaces and its ability to communicate with the Flukso server.
From left to right, these LEDs are:
- Wifi
- If the wifi interface is enabled, the wifi LED will light up when the
wireless connection is succesfully established. Network traffic crossing the
wifi interface will trigger a blinking LED.
- Ethernet
- Both ethernet LED will be on when their respective ethernet links, WAN/LAN,
are established. This can either be a 10baseT or 100baseTX link in full- or
half-duplex mode.
- Globe
- After the Fluksometer has finished its boot sequence, the globe LED will
be on when it can connect to the Flukso server via MQTT/SSL.
- Heartbeat
- The heartbeat LED is positioned right next to the globe led. While the
globe LED informs us about the status of the Fluksometer’s external
communication, the heartbeat LED allows us to monitor the Fluksometer’s
internal health. This LED will be on when the sensor board is running its
firmware. From the moment the flx daemon is started during the boot
sequence, it will ping the sensor board every second. Each ping triggers
a blink of this LED, thus mimicking a real heartbeat. Hence, a ’heartbeat’
is an indication of fully booted Fluksometer, an active flx daemon, a
sensor board running its firmware and proper communication between the main
board and sensor board.
- Power
- The power LED is directly connected to the internal 3.3V supply. A burning
LED indicates that power has been applied to the device and the internal
3.3V voltage regulator is working properly.
