EN50160 External Controls
To access these controls, double-click the Controls grouping object on the EN50160
tab in a default Power Quality Vista diagram.
Enabling the EN50160 Calculations
EN50160 statistics (counters N, N
1
, etc.) monitoring and logging are enabled when:
External Boolean module "EN50160 Enable" is ON (=1) (the default).
Sag/Swell module’s "Nominal Voltage" setup register has a value > 0. By default,
this register is set to 0. You can set this value from the meter’s front panel as well
as in Designer.
In addition to the above, EN50160 parameter logging (logging of the EN50160
voltage measurements themselves) is enabled when:
External Boolean module "PQ Prm Rc Enbl" is also ON (=1). To conserve
memory, parameter data logging is disabled (OFF) by default.
Double-click this control object to enable EN50160 parameters to be logged.
EN50160 Reset
EN50160 statistics (counters) and parameter data are cleared from the meter when
the External Pulse module "EN50160 Reset" is triggered:
Double-click this control object to clear the External Pulse module, or use the
Setup Menu in the meter’s front panel.
The logged EN50160 quantities (data logs) are preserved.
EN50160 Synchronization Mode & Synchronization Timing
These control objects allow you to choose a Free or Scheduled synchronization
mode for the EN50160 data acquisition. If you select Scheduled, then you can opt
for Synchronization Timing to start at midnight of the present day, or at midnight
of the coming Saturday. If you select Free, then EN50160 statistics and data start
accumulating after the first EN50160 Reset (see above).
By default, all cumulative EN50160 parameters are scheduled to synchronize every
Saturday at midnight. You can alter these settings through links to two External
Boolean modules:
PQ Sync Mode (External Boolean 23)
PQ Sync Tdy/Sat (External Boolean 24)
