CARE AND MAINTENANCE
The NetThings Energy Manager and Display require no regular maintenance. Do not spray with water or any cleaning
products, which may damage the surfaces or cause a risk of electric shock.
SERVICE AND REPAIR
This equipment is NOT user serviceable.
Please do not dismantle the unit. For alterations to the connected utilities please consult a suitably qualified electrician.
In the unlikely event of a fault developing please refer to www.netthings.co.uk.
VERIFICATION OF PULSES
Any of the following could prevent NetThings Energy Manager recording use of energy on the pulse connections.
•
Faulty secondary equipment not supplying any pulses
•
Reversed polarity on the interconnecting cables from meters to Energy Manager. Pulses generated by a transistor
logic (TTL) output should have their polarity observed and maintained. Meters with mechanical pulse outputs are not
polarity dependant.
•
Breaks in the interconnecting cables from meters to Energy Manager
•
Installing cables exceeding the distance specified in IEC-62053-31 (100meters)
•
Installing incorrect pulse cable type (Belden 9501 or similar is recommended)
•
Incorrectly connecting pulse inputs to CT connections and vice versa
M-BUS DATA
M-Bus data received is processed and presented to the user under the following circumstances:
Consumed energy readings are collected every minute and updated every minute in the historical charts.
Power/ Instantaneous Consumption values are updated differently depending on the meter:
•
Netthings Supported Heatmeters:
Values are read directly from the meter at the same time as the energy readings.
•
Water Meters & Unsupported Heatmeters:
The value is a rolling average of the past 15 minutes of energy measurements.
