Error codes Sometimes an error code will appear in display sequence 15, 37, 47, 74 and on M-Bus. The error code message can be interpreted using the table below. The error codes consist of three (3) hexadecimal (Hex) digits, e.g. 0 – 15. Each digit can have up to 4 different error codes in combination.
4 Seals, calculator protection The F2/3/4 are tampering protected with seals. To enter the calculator or to enter “Test mode”, “Service mode” or to enter the electronics inside the calculator several seals need to be broken, see placement of the seals below: Fig 4.1, F2 Placement of seals Seals 1.

Zero sequence current When connecting the calculator to input or outputs one need to be aware of the possibility of “Zero sequence current” can cause problems in the input/output systems, such as no signals, error readings, parity errors and in worst case damaged circuits in the system.
6 Calculation F4 calculator is in accordance with EN1434:1997, part 1 and 2, measuring and calculating energy. 6.1.1 Momentary flow calculator fulfils the requirements The momentary flow is calculated at the end of an environmental class C, in accordance with averaging period of 4 seconds, normally set in the EN1434:1997 part 4 calculator.
Calculation of power Storing values The calculated flow, see above is used by the meter The calculator stores the measured values at each dayshift (at 00:00 each day) or when “Save data” to calculate the power and this value is added to the previously stored power values.
7 Testing, programming & service To ensure the functions in the F3/F4 test can be performed. Programming the calculator Display test The calculator parameters can be configured by By selecting display sequence “12” the LCD entering the calculator “Service mode” or “INIT mode”, see Service 7.4.
