Factory Defaults
E-Flo Plus System Specific Parameters (menu 20
parameters)
All of the E-Flo Plus features are controlled by menu 20
parameters. VFDs are shipped with these parameters
set to default values (refer to Table 2 on page 16 for
more information). Factory defaults can be loaded as fol-
lows:
1.
Disable the drive through Secure Disable (if a Graco
Local Control Box is used, press the red
mushroom-type Secure Disable button).
2.
Navigate to Pr 20.16 and set its value to 1234. At
this time the program defaults will be loaded and
number 1234 will automatically be replaced by 0.
E-Flo Plus Motor Specific Parameters
VFDs are shipped with all motor parameters defaulted to
a Graco UL motor. It is essential to check motor selec-
tion (page 9) and either:
•
if Graco ATEX motor is used, reload motor defaults
(see Graco Motors, page 9)
•
if non-Graco motor is used, set all motor parameters
(see Non-Graco Motors, page 9).
SMARTCARD Defaults
Default Graco parameter values for menus 0 through 22
are saved on SMARTCARD in location #101, as differ-
ences from the drive defaults (Code 4101); see the Con-
trol Techniques manual for further information. Use
Code 6101 to load Graco defaults.
System-related Graco default parameters (menu 20)
may be loaded by navigating to Pr 20.16 and setting its
value to 1234. Note that Pr 20.16 will be automatically
reset back to 0.

of an error in calibration or accidental parameter alter-
ation.
