LOAD PERCENTAGE
The actual load is indicated by LEDs as a percentage of the nomi-
nal load.
• All LEDs off => Actual load = 0 - 10%
• Green LED 20% cont. illumin. => Actual load = 10 - 30%
• Green LED 40% cont. illumin. => Actual load = 30 - 50%
• Green LED 60% cont. illumin. => Actual load = 50 - 70%
• Green LED 80% cont. illumin. => Actual load = 70 - 90%
• Green LED 100% cont. illumin. => Actual load = 90 - 100%
• Red LED 125% cont. illumin.
=> Actual load = 100 - 125%
