SINEXCEL 7-INCH HMI HIGHER LEVEL PASSWORD PARAMETER INTRODUCTION

Parameter
This function is not used for SVG; it can realize capacitive
reactive power compensation.
Enable: then module can do bi-directional reactive power
compensation;
Capacitive
Disable: Module can only do inductive reactive power
Comp.
compensation
LVRT: Low Voltage Ride Through
Enable: If supply voltage drops below 90% of voltage lower
limit for more than 2s that module will stop working.
Disable: The module only works in its entire voltage tolerance
range. Once lower than voltage limit, module will stop
working.
For example, SVG 400V (It's voltage range is 228~456V )
that means when you choose "Enable" to work, when the
LVRT
voltage drops the voltage lower voltage(228V) 90%( below
205, 2V), the time lasts 2s or more, the SVG will stop working
automatically, but within 205, 2V, the SVG still working.
If "Disable" is selected, the SVG will stop working when the
voltage reaches the lower limit (228V).
Note: ① The voltage lower the compensation performance
will be worse. ② Please contact engineer of Sinexcel before
changing this parameter.
This function is not used for SVG.
Grid Voltage Adjust is bind with Target Voltage and Voltage
Upper/Lower Limit (%). If Grid Voltage Adjust function is
Grid Vol. Adjust
Disabled, the settings for the upper voltage and lower voltage
limit are invalid.
Set the voltage target value. When the system voltage falls
below or exceeds the target voltage range, the machine
outputs reactive or perceived power to compensate the
voltage.
Used with "Target Vol", "Vol. Upper Limit (%)", "Vol. Lower
Limit (%)" settings. In order to stable the system voltage
within certain range by outputting inductive/capacitive
reactive power; this function is not commonly used, if there're
sites the voltage fluctuates when there's big motor's starting,
then we can configure with SVG to regulate the voltage.
Note: Please contact engineer of Sinexcel before changing
this parameter.
