If the value entered is lower than the minimum value or higher than the maximum value,
the backlight of the display flashes and the value entered is replaced with the minimum or
maximum value, or with the last value validated.
Press the
key to access the next programming step.
If no keys are pressed for 5 minutes, the unit switches to the simulation screen,
“5.27.-
SIMULATION SCREEN”
.
5.23.- CURRENT x I THD ALARM
In this point the thresholds above which the alarm
for the percentage of the value of the current x
ITHD (
E09
) is activated can be configured.
The alarm must be enabled (
“5.19.- ENABLING
ALARMS”
)
The programmed values are useful for the 3
phases which the unit measures.
Press the
key to enter editing mode. It is
identified by the
symbol and the blinking of
the digits to be modified.
The value to be programmed in this alarm corresponds directly to the value of the total
harmonic current to be considered as the setpoint.
For example:
If you want to program a
Lo
setpoint value when exceeding a harmonic current of 200 A measured by the regulator, program
00200
directly in this section.
The parameters to be configured are:
The
Lo
value:
when the unit exceeds this value for 30 minutes, alarm
E09
is
triggered, and if alarm
E11
is enabled
,
the
Controller MASTER control VAR FAST
unit
enters
No Connection
status and activates
alarm
E11
.
The
HI
value:
if the unit exceeds this value for 30 seconds, alarm
E09
is triggered,
and if alarm
E12
is enabled, the
Controller MASTER control VAR FAST
unit enters
the
Disconnection
status and activates
alarm
E12
.
If the unit falls back under the
Lo
value for 10 minutes, it deactivates the alarms and returns
to the normal operating status.
In the
No Connection
status, the unit does not connect the stages, but also does not
disconnect them if the operation requires it.
In the
Disconnection
status, it disconnects all the stages and does not allow them to connect.
The
key increases the digit value.
