Table 30 Ð Variable Frequency Drive (VFD) Display

DISPLAY			ACTION
Fref	Not used.
Fout	Displays the output frequency at which the VFD is cur-
	rently operating. This is a display only function. The user
	cannot change this displayed value.
lout	Displays the level of output current that the VFD is cur-
	rently producing. This is a display only function. The user
	cannot change this displayed value.
kWout	Displays the output power that the VFD is currently pro-
	ducing. This is a display only function. The user cannot
	change this displayed value.
F/R	Sets the rotation direction of the motor when a run com-
	mand is given.
Montr	Press	ENTER	to access the monitor parameters
	(U-01 through U-13).
Accel	Not used.
Decel	Not used.
Vmtr	Sets the rated voltage of the motor.
V/F	Sets a preset V/f pattern or allows a custom V/f pattern
	to be set.
Fgain	Sets the frequency reference gain for the analog fre-
	quency reference.
Fbias	Sets the frequency reference bias for the analog fre-
	quency reference.
FLA	Sets the full load amps used for detecting motor over-
	load. When FLA is set to 0 it is disabled.
PID	Enables or disables the PID.
kWsav	Enables or disables the energy saving function.
PRGM	Allows parameter programming.

SERVICE

Service Access Ð All unit components can be reached through clearly labeled hinged access doors. These doors are equipped with tiebacks, but if heavy duty servicing is needed, it is recommended that the doors be removed or propped open.

Each door is held closed with 3 latches. The latches are secured to the unit with a single 1¤4-in. 220 x 1¤2-in. long bolt. See Fig. 50.

To open, loosen the latch bolt using a 7/16-in. wrench. Pivot the latch so it is not in contact with the door. Open the door. To shut, reverse the above procedure.

NOTE: Disassembly of the top cover may be required under special service circumstances. It is very important that the orientation and position of the top cover be marked on the unit prior to disassembly. This will allow proper replace- ment of the top cover onto the unit and prevent rainwater from leaking into the unit.

IMPORTANT: After servicing is completed, make sure door is closed and relatched properly, and that the latches are tight. Failure to do this can result in water leakage into the indoor-air section of the unit.

REMOTE Mode indication LEDs. The LEDs light when REMOTE Mode has been selected.
