E-Flo Plus Features

Drive Active (System ON) Output

Drive Active Pr 10.02 is mapped to the VFD relay out-
puts available at terminals 41 and 42. The relay contacts 
are open when the motor is not running (Pr 10.02 = 0, 
which means the drive is inactive). The relay contacts 
are closed when the motor is running (Pr 10.02 = 1, 
which means the drive is active).

Jog Mode

Jog mode allows the user to run the pump at the slow 
speed and to stop it at a desired position. Note that park 
angle allows easy access to the stand-side lower. Jog 
mode can therefore be used to stop the pump at an 
angle which will allow easy access to the motor-side 
lower. Jog speed is equivalent to the following flow rates:

2000cc lowers: 2.7 gpm (10.2 lpm)

1500cc lowers: 1.9 gpm (7.3 lpm)

1000cc lowers: 1.4 gpm (5.4 lpm)

Jog Mode in Local Control

Hardware

Jog mode requires a momentary, normally open switch. 
Graco offers a control box with jog switch installed. If 
local control box is used and Local/Remote switch is set 
to Local, jog mode can be initiated by pressing momen-
tary “Jog” switch. Digital I/O #6 (Pin #29) is configured 
for the Jog mode (see System Electrical Diagrams
page 36). Normally open (N.O.) position of the switch 
disables jogging and closed position of the switch (Pin 
#29 connected to common) enables jogging.

Operation

To initiate Jog mode, press and hold the jog button. Jog 
mode will stay active as long as the jog button is 
pressed. When the jog button is released, the system 
will stop.

Jog Mode - Keypad / Modbus Control

Parameter Pr 20.01 is allocated to control system 
modes. Jog mode is mode #2. In order to initiate jog-
ging, navigate to Pr 20.01 and set its value to 2. At this 
time the system will enter the Jog mode.

When the pump has reached the desired position, stop 
the system using one of the following methods:

Put the system in Park by setting Pr 20.01 to 3, or

Initiate the Stop command by using the red 
Stop/Reset button or via Pr 20.25 (see Running the 
Pump
 on page 18 for details).

Park Mode

Park mode allows you to park the pump in a position 
allowing easy access to stand-side lower.

Park Mode in Local Control

Jog button has a dual function – Jog and Park. To 
access the Park mode, press and release the switch in 
less than 1 second. 

Park Mode – Keypad / Modbus Control

Parameter Pr 20.01 is allocated to control system 
modes. Park mode is mode #3. To initiate parking, navi-
gate to parameter Pr 20.01 and set its value to 3. The 
system will enter the Park mode. See Jog Mode instruc-
tions.

IMPORTANT: Once system is stopped and jogging 
is no longer required, change Pr 20.01 back to 0.
