| Status
Indicators |
| FAULT Indicator |
Illuminates in one of the following cases: |
| - Power Supply malfunction (voltage or
frequency) |
| - Internal malfunction (hardware). |
| REMOTE Indicator |
illuminates when the PA is controlled by a
computer (REMOTE mode
where all soft keys are disabled). |
| RELAY Indicator |
Illuminates when the relay is connected. |
| GEN. Indicator |
Illuminates when energy flows from the load to
the network (generally,
this occurs when generator is being used, and the
active power flows in the opposite direction). |
| ELSPEC Logo Indicator |
Illuminates to indicate mains supply to the
Power Analyzer. |
| |
| Display
Controls |
| |
| 7-Segment Display |
Comprises four 7-segment LEOs. |
| CAP/IND. Indicators |
Illuminates when the power factor is within the
capacitive and
indicative ranges respectively. |
| Note |
The CAP. and IND. Indicators are used only for
power factor (cosq» and reactive power (Q)
measurements. |
| DISP. Softkey |
Selects the parameter to be displayed |
| Display Parameter
Indicators |
The parameter which is selected by the DISP.
Soft key is marked by the pertinent LED. The LEDs are
arranged in two rows. Switching between parameters
is carried out in a cyclic manner by sequentially
pressing the DISP. Soft key. |
| HARM.# Softkey |
Selects the harmonic number (3,5,7, 9, or 11)
when measuring H , H or H |
| NORM./MIN./MAX. |
Selects one of the following display modes |
| Soft key |
- NORM. Real-time normal
display.
- MIN or MAX Minimum or maximum
accumulated value displays are displayed
respectively. |
| |
| Mode of Operation Controls |
| |
| INTEGR. Soft key and
Indicator |
Pressing this soft key will switch the Power
Analyzer into the integration mode and the indicator
will illuminate. In the integration mode the cosq>
value is determined according to the average power
factor which is measured during elapsed time (the
elapsed time, is defined by the period of time
between the programmed time and current time). |
| MODE Softkey |
Selects one of the following modes of operation
| LOAD 1 |
Is selected. |
| LOAD 2 |
Is selected. |
|
| PROGRAM / ELAPSED
TIME |
Illuminates when the PROGRAM mode is selected
(the LEDTIMEilluminates), or the elapsed time mode
is selected. Elapsed Time Mode: Using the arrow
soft keys, enables determination of the elapsed time.
The elapsed time since the last INTEGER. RESET is
shown on the display in three different modes (the
arrow soft keys ca.n change same by scrolling)
day/hour, hour/min or min/sec. Program Mode: used to
set box parameters, such as current transformer
ratio, voltage etc. Note: Parameter Settings can be
accessed by pressing HARM. + DISP. soft keys
simultaneously for at least three seconds. |
| Arrow Softkeys |
During PROGRAM/ ELAPSED TIME mode, these
softkeys are used to increase or decrease the value
of the selected parameter (Program mode)
or to select the elapsed time (Elapsed mode). |
| INTEGR. RESET |
This soft key is used to reset the elapsed time
(when MWh is selected). This operation is performed
by pressing this soft key for at least three seconds. |
| PHASE Softkey
Indiacators |
This soft key selects the phase to be used as
control and measurements reference. When a phase is
selected, the pertinent indicator illuminates. |
