Our Electricity Monitoring solution gives you real-time access to your consumption data. The installation is simple and gives you the ability to quickly spot trends in your energy usage and to identify inefficiencies.
This guide will focus on how to install Fludia's LED Pulse Counters. The LED-pulse counters directly relay the power consumption by monitoring an electrical ‘pulse’ emitted from an electricity meter. They are attached to the external face of a meter and use a fixed ratio to convert LED pulses to power consumption.
Remember: We currently do not supply new meters to measure power consumption. This means that we are reliant on an existing, compatible meter being in place to install our LED-pulse sensor.
Step by Step Guide
The sensor(s) you will be installing is FM232e and it will rely on a gateway(s) to transmit pulse counts back to the cloud.
Remember: The gateway will need to be installed before the sensors, for a guide on the gateway install see here.
Pairing FM232e sensors to a gateway
Remember: The F-Link uses the same moulding as the FM232e transmitter box therefore look very similar. The sticker on the device can be used to identify them.
To begin put the Fludia F-Link into pairing mode:
Press twice on the F-Link button located on the side of the device. The yellow LED should start to blink, indicating the pairing mode has been activated. The F-Link will default to standard mode after 5 minutes.
Next initiate pairing mode on the sensors:
Connect the cable between the optical head and the radio/battery box on the FM232e.
Once initiated, the LEDs on the FM232 box will show the progress of pairing:
LED | Status |
Red and Green LED blinking together | Pairing in progress |
Green LED blinking alone | Pairing successful |
Red LED blinking alone | Pairing failed |
If the sensor is already paired
If the LEDs on the FM232e blink green twice, red once, green twice red once and so on, the device is already paired with a F-Link (but not necessarily the one you are trying to pair with now).
To reset the device pairing, remove the batteries from the FM232e, wait 10 seconds, then reinsert the batteries. This will allow the sensor to be paired again with any F-Link.
Pairing complete
When the yellow LED stops blinking on the F-Link, the pairing process has been completed successfully. To pair another sensor, begin the process again from step 1
Sensor Installation
Once the sensors have been paired with the gateway, they can be installed on the required meters.
Locate the LED pulse output on the meter, this would be the one on the right hand side like the image below. Lookout for Wh or kWh.
Remember: do not install on the LED with VARh units as this is the reactive power.
There will be a visible LED light on the front of the meter that the device needs to be placed over.
Apply the self-adhesive mounting bracket
Clean the face of the meter, detach the bracket from the pulse counter using the black thumb-screw and apply the bracket over the LED pulse output on the meter using the self adhesive backing.
The LED must be visible through the bracket for the counter to function correctly.
LED Pulse - Bracket Installation
Re-attach optical counter to bracket
Once the bracket is securely located on the meter, re-attach the optical counter to the bracket using the black thumb screw. Ensure the white cable is connected to the base of the sensor and the battery/transmitter box.
IMPORTANT: Ensure the mode selector switch on the pulse counter is in position B. If this switch is in the incorrect button, the sensor will not work correctly and will need to be re-attended to switch to the correct position.
Pulse counter in mode B. The mode letters are moulded into the plastic casing.
Check pulses are registering
Once installed, the LED on the optical pulse counter should flash red.
The LEDs blink:
A: Calibration: red LED blinks for 20 seconds
B: Validation: green LED blinks every time the meter light blinks
C: After 3 minutes, the green light stops to preserve battery life
The FM232e battery/transmitter box will flash Green-Green-Red. This means it is paired with a gateway.
This will stop flashing after 30 seconds.
