10 CHANGE PAS
: this function allows the user to modify the PASS value
with a new value (from 0 to 1000).
20 BACKLIGHT:
backlight time from 0 (always on) to 255 minutes.
30 MODULES:
the WM30 96 does not support the automatic ackno-
wledgment of the installed modules, therefore this information must be
entered using the “MODULES” menu.
40 APPLICAT.:
this function which enables a simple, quick, clear and
immediate visualization of the instrument measurements, making available
only specific variables (page 4/5) depending on the application of the
instrument.
50 SYSTEM:
this function allows the user to select the type of
electrical system.
60 CT RATIO:
this function allows the user to select the
value of the CT ratio (primary/secondary ratio of the current transformer
being used). Example: if the CT primary (current transformer) has a current
of 300A and the secondary a current of 5A, the CT ratio corresponds to 60
(obtained using the following calculation: 300/5.
70 PT RATIO:
this function allows you to select the value of the VT-PT ratio
(primary/secondary ratio of the voltage transformer being used). Example:
if the primary of the connected VT (voltage transformer) is 20kV and the
secondary is 100V, then the VT-PT ratio corresponds to 200 (obtained car-
rying out the following calculation: 20000/100).
80 DMD:
This function allows the user to select the calculation method of
the DMD/AVG value of the selected variable. 81 TYPE: select the type of
calculation mode to be used for the DMD/AVG calculation FIXED: if, for
example, a time interval of 15 minutes has been selected, the instrument
will calculate the AVD/DMD value of the measured variable and updates its
value every 15 minutes. SLIDE: if for example a time interval of 15 minu-
tes has been selected, the instrument calculates the AVG/DMD value and
updates its value at the beginning after the first 15 values and then after
every minute, thus generating a window whose width is of 15 minutes and
that moves forward every minute. 82 TIME: select the time interval for the
DMD/AVG calculation 83 SYNC: select the synchronization mode, that is
the method that controls the calculation method of the average/demand
according to the selected time.
90 SET POWER:
This menu allows you to set a power value (installed power)
that, in the measuring phase, will represent 100% of the graph indicator.
100 HOME PAGE:
This function allows the user to select the variables to
be displayed on first page (home page). 101 TYPE: A, you can select the
variable for each row. B, you can select a preset combination of variables.
110 FILTER:
Thanks to the digital filter, it’s possible to stabilize the mea-
surements which are too instable when displaying the relevant values. 111
FILTER S: set the operating range of the digital filter. The value is expres-
sed as a %. 112 FILTER CO: set the filtering coefficient of the instantane-
ous measures. By increasing the value, also the stability and the settling
time of the measures are increased
.
Some specific menus display only if the relevant modules are instal-
led
