Control Indicator
Status Indicators
| FAULT Indicator
|
Illuminates in one of the following cases: |
| |
- Power Supply malfunction
(voltage or frequency)
- Internal malfunction (hardware).
|
| |
|
REMOTE Indicator |
lluminates 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. |

| 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 |
The parameter which is selected by the DISP. Softkey is |
|
Indicators |
marked by the pertinent LED. The LEDs
are arranged in two |
| |
rows.
Switching between parameters is
carried out in a |
| |
cyclic manner
by sequentiaaly pressing the DISP. Softkey. |
|
| |
| 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
|
Pressing this softkey
will switch the Power Analyzer
into the |
|
Indicator |
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 |
Illuminates when the PROGRAM mode is selected (the LED |
|
TIME |
illuminates), or the elapsed time mode is selected.
Elapsed Time Mode: Using the arrow softkeys, enables determination
of the elapsed time. The elapsed time since the last INTEGR. RESET
is shown on the display in three different modes (the arrow softkeys
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. softkeys simultaneously for at least three seconds. |
|
| |
| Arrow Softkeys |
During PROGRAM/ ELAPSED TIME mode, these softkeys are used to |
| |
ncrease or decrease the value of the selected parameter (Program mode) or to select the elapsed time (Elapsed mode). |
|
| |
| INTEGR. RESET |
This softkey is used to reset the elapsed time (when MWh is |
| |
selected). This operation is performed by pressing this softkey for at least three seconds. |
|
| |
| PHASE Softkey |
This softkey selects the
phase to be used as control and |
| Indiacators |
measurements reference. When a phase is selected, the pertinent indicator illuminates. |
