If the value entered is lower than the minimum value or higher than the maximum value,
the backlight of the display ashes 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.
