3. Compressor Control

W-2WAY ECO-i SYSTEM Control Functions

(2)Current Protection

Inverter compressor current control is composed of primary current control and secondary current control. Current protection control for the inverter compressor is performed by self-protection in the inverter circuit, and does not increase or decrease the compressor capacity.

		Primary current	Secondary current			Control
1	-		75.0A or (302°F)			Inverter compressors stop (HIC auto. protection)
						Inverter compressors stop (When 100ms is detected,
		16.0A~	16.5A			current protection works.)
		14.5A~				Hz decrease in the inverter compressor
			13.5A
		13.5A~
			13.0A		12.5A
				Prohibit Hz increase in the inverter compressor
						12.0A
					Permit Hz increase in the inverter compressor
				80Hz 90Hz

3-6-4. Roadmap Control after Trip

When restarting after the trip stop occurs, the horsepower may increase slowly depending on the trip counter value.

(1)If trip counter =1, the horsepower increases at a speed that is 1/2 of ordinary roadmap control.

(2)If trip counter =2, the horsepower increases at a speed that is 1/3 of ordinary roadmap control.

The trip counter will be cleared if no trip occurs within 10 minutes after operation starts.
