Maximum, Minimum Ve Demand Menus - WEG MMW03-CH User Manual

ATTENTION!
L1, L2, L3 LEDs blink simultaneously and very slowly (per second)
Any/All of L1, L2, L3 LED(s) blink(s) slowly (per 0.5 second)
Any/All of L1, L2, L3 LED(s) blink(s) quickly (per 0.2 second)
ATTENTION!
When the product is mounted on a panel which consumes power, active power (P) must be positive. If active power (P1, P2 or
P3) display is blinking in L-H and/or instantaneous menu, operator should cross connect k-l leads of the current transformer.
ATTENTION!
999 000 000"(999 MEGA) is the highest number that can be displayed in 7 segment displays of the product.
If this number is exceeded:
- Related "k", "M" LEDs will turn on (flash constantly).
- "888" number will be monitored in the related 7 segment display. This phenomenon applies for "Instantaneous" and "L-H"
menus.

3.2 MAXIMUM, MINIMUM VE DEMAND MENUS

Minimum and maximum values are calculated and stored in the non-volatile memory for below parameters.
„ Voltage (phase-neutral, phase-phase)
„ Neutral current
„ Frequency
„ CosØ
„ Power factor
„ THDV
„ THDI
Besides maximum and minimum values, demand values are calculated and stored in the non-volatile memory
for below parameters.
„ Current
„ Active power
„ Reactive power
„ Apparent power
Use the left or right arrow keys to display the max. and min. measurements and demand values within the
measurement menus. Table 3-1 shows the menu movements. Table 3-2 shows the indicated values and active
LEDs in the corresponding menu.
