4.5.2
SMART FLO CONTROLS:
(For units equipped with a Smart-Flo Control
Panel only)
Each customer is responsible to provide the appropriate
control panel and power supply to the machine. It is
recommended that the customer have a licensed electrician
provide the power per ANSI/NFPA70 Standard and all
applicable local codes when providing power to the motor.
The Smart Flo System can be wired into a large control room
away from the machine.
Be familiar with the specific control box system before
starting.
1.
SMART FLO CONTROL PANEL:
a. Start:
This green two-position push-button switch is used to
turn power ON to the VFD. Depress the switch to turn
power ON. When the button is depressed, the blower
running light will illuminate, then after a 30 second
delay, the A/L running light will illuminate.
b. Stop
This red two-position push-button switch is used to
turn power OFF to the VFD. Depress the switch to turn
power OFF. When the button is depressed, the A/L
running light will turn off, then after a 30 second delay,
the blower running light will turn off.
c. Kill Button:
The kill button immediately stops the blower and the
airlock, regardless of external commands.
d. Airlock Running:
This light is illuminated when the airlock is running,
and turns off when the airlock stops.
e. Blower Running:
This light is illuminated when the blower is running,
and turns off when the blower stops.
IMPORTANT !
The blower is designed to run for approximately
30 seconds before the airlock turns on, and will
continue for 30 seconds after the airlock shuts
down. This insures the lines are empty before
turning off all air flow.
f. Auto/Manual Selector:
This 2 position selector switch is used to select the
running mode of the Smart Flo panel. Auto allows the
system to adjust the blower speed based on product
volume, condition, and conveying distance. Manual will
allow a preset speed to be set, causing the smart flow
system to run at exactly that speed. The system
should always be set in auto unless the system is
running poorly.
g.
Speed Selector:
This 3 position selector switch is used to select different
blower speeds. Low, medium, and high set the idling
speed of the blower. Generally, the low speed position
will work at all times, however if plugging occurs select
medium or high. This selector only effects the blower
speed when the system is in auto.
h.
Speed Dial.
This variable position dial allows the blower speed to be
set when the Smart Flo system is in manual.
2.
RESET PROCEDURE:
If the Smart Flo panel is receiving an external run signal
(starts and stops from a drier), and the kill button is
depressed, a reset procedure needs to be followed.
Release the kill button
Press the start button
Press the stop button
The external signal will now control the blower and airlock
again.
3.
POWER
DISCONNECTS:
The system is
designed with
switches close to the
machine that allow the
operator to disconnect
the power to the
respective motors as
required. Turn the
switch to its vertical
configuration to
provide power to the
motor, and horizontal
to disconnect power.
