Serial number- displays serial number and it is unique for each regulator.
Firmware version – displays actual regulator firmware version.
Date (regulator) – it indicates the real time running inside the regulator (date part).
Time (regulator) – it indicates the real time running inside the regulator (time part).
Note:
Regulator real time is backed up with a built-in lithium battery, so it runs even if the regulator power
supply is turned off.
Date (client) – it displays the real-time running on the PC (date part).
Time (client) – it displays the real-time running on the PC (time part).
INPUT SETTINGS TAB
In this tab you may set measuring inputs, multi-purpose ANDI inputs and configure digital temperature
sensors.
Note:
The ANDI multi-purpose inputs are an extension of FB input functionality from older WATTrouter models
that only worked as S0 pulse counter.
Common settings for Measurement input settings and ANDI input settings:
Label – used to assign a label for the relevant input. Label may contain a maximum of 16 characters
in ASCII encoding. For ILx inputs it cannot be modified.
Function – is used to select proper function for the input. For ILx inputs it cannot be modified. The
ANDI inputs may perform following functions:
a.
Power measurement – default function. Connect WATTrouter-compatible external current
transformers (e.g. another current sensing module or other compatible current measuring
transformers). Do not overload the ANDI inputs with bigger primary currents than 15A (which
corresponds to secondary current 15mA);
b.
S0 pulse counter – connect impulse output S0 of an external meter, which meets the parameters
specified in the technical specification and its output signal provides information about the
measured electrical energy;
c.
NTC – connect analog temperature sensors of NTC type;
d.
PT1000 - connect analog temperature sensors type PT1000.
Current orientation - it is used to change the sign of measured powers, if the current sensing module is
fitted in reverse position, or in cases for example, when it is desirable to pass the wire through the
module in reverse direction.
Phase - it is used to set the physical phase to given input when its function is set to power
measurement. Assign the phase so that the measured currents are in phase with voltage. Check the
assignment using a control oscilloscope and a purely resistive (thermal) load on the given phase.
Note:
The Phase parameter replaces the "Phase Order Setting" menu from older WATTrouter models and
allows you to set any phasing for all inputs with the power measurement function.
Ratio for external CTs - set this ratio only if you use additional external current transformers (CTs),
whose secondary coils are shorted with a wire passing through measuring coils of the current sensing
module, as specified on figure 7. If you use standard connection for WATTrouter device that is, the
facility or household supply wire is passing directly through measuring coils as specified on figure 3,
then this ratio should be 1:1 (however, this ratio can also be used to calibrate current measurement
