This chapter introduces the operation of the power distribution LCD, procedures of adding loads and rectifiers.
5.1 Power Distribution LCD Operation
LCD Operation Of PD380/400AFH and PD380/630AFH AC distribution cabinet and DC distribution cabinet
The power distribution LCDs can display AC/DC power distribution data of communication power supply system.
They are mounted on the front door of AC and DC distribution cabinet.
Six keys are positioned below the LCD.
▲,
▼
: Scroll the screen.
◄, ►: Adjust the display brightness.
ESC: Exit language switch interface without changing the language.
ENT: confirm the language switch.
There are 20 levels of display brightness for adjustment and the displayed contents vary depending upon the different
distribution forms.
If left idle for about 8mins, the backlight will be off and the display will switch to the original screen. When you set
parameters for the power distribution cabinet through the controller, the display will switch to the original screen if the
currently displayed parameters are changed.
The LCDs of AC distribution cabinet are shown below:
Screen 1:
ESC to Quit
To Chinese
ENT to Run
Screen 2:
AC Distri 1
Stat: Run Normal
Ctrl Mode: Manual
Light Stat: On
The possible state of AC Distri 1: run/backup, normal/power failure/imbalance
The possible indications of Ctrl Mode: manual/automatic
The possible indications of Light Stat: off/on
Screen 3:
AC Distri 1
Ua: 380V
Ub: 402V Over
Uc: 180V Under
or
AC Distri 1
Uab: 380V
Ubc: 402V Over
Uca: 180V Under
or
AC Distri 1
Volt: 90V Under
The possible indications of AC 1 voltage: 3-phase line voltage, 3-phase phase voltage or 1-phase phase voltage
The possible indications of AC voltage corresponding state: over/under/phase loss
When the LCD displays 3-phase or 1-phase phase voltage, the AC voltage alarm corresponds to the displayed phase
voltage. When the LCD displays 3-phase line voltage, if the Ua voltage exists phase loss there will display phase loss
at the back of Uab voltage; if the Ub voltage exists phase loss there will display phase loss at the back of Ubc voltage;
