to heed a warning symbol could lead to personal injury
and/or damage to the unit or other equipment.
Heed all warning symbols that appear in this document,
the operator’s manual, or on the equipment.
WARNING: Failure to observe this warning may
result in personal injury, death, or equipment
damage.
WARNING: Risk of electrical shock. Failure to

or death or equipment damage.
SystemComponents
See Figure 1. The Pro-Flo Controller automates the
control of Pro-Flo guns. Use the operator interface (3) to
select and define production parameters. The diagnostic
panel (5) displays the system status. Use the LAMP
TEST key (4) to test the lights on the panel. When a
fault is detected, the alarm tower (1) lights and the type
of fault is indicated on the diagnostic panel. The robot
signal indicators (2) on the diagnostic panel light when
signals are received from the robot controller. Under
normal operating conditions, these lights flash on and off
in a specific sequence.

Fault Correction
When a Pro-Flo system fault is detected, the alarm tower
lights and the diagnostic panel indicates where faults
occurred. Select the HELP screen to display a
description of the fault and corrective action.
Bead Size Adjustment
Bead size is an arbitrary number between 1 and 99. The
current bead size is displayed on the bead size indicator.
Use the bead adjustment keys to increase or decrease
the bead size.
Purging
Purge the gun before you use it to remove air from the
material supply hose and nozzle. Press the ON key to
start purging. The purge indicator lights while the gun is
open. Purging will stop after the purge time has elapsed.
Press the OFF key to stop purging immediately.

Set Up
Set the parameters for Pro-Flo dispensing from the
SET-UP screen. Highlight and select SET-UP, then
highlight and select any of the following prompts:
Material Calibration
NOTE: Material is dispensed during this operation.
Place a waste bucket under the gun.
Run a material calibration after the controller is installed
and whenever the type of dispensing material is
changed. Material calibration allows the controller to
learn the material’s shear thinning properties. When this
prompt is selected, the controller runs an automatic
routine for up to 5 minutes while dispensing material.
Purge Gun
Set Dispense Time to determine how long the gun stays
open each time the Purge ON button is pressed. Enter a
Dispense Time from 1 to 60 sec.
Delay Time
The Tool Speed and gun delay times determine how fast
the digital controller reacts to signals received from the
robot controller. Sometimes delays are necessary to
prevent the controller from reacting more quickly than the
robot or gun.
Set Tool Speed to delay the digital controller’s reaction to
robot motion. Enter a Tool Speed delay from 0 to
500 msec.
Set Gun On and Gun Off to delay the digital controller’s
reaction to the gun-on and gun-off signals from the robot
controller. These parameters adjust the start and stop
time of material dispensing. Enter Gun On and Gun Off
delays from 0 to 500 msec.
SPC
Use the SPC (statistical process control) screen to clear
data from the SPC queue or to download it to a PC
running the Nordson DataLink program. Refer to the
Nordson DataLink User’s Guide for more information.
Flowmeter
When a new flowmeter is installed, enter its flow rate (or
K-value) in counts/liter. Enter the K-value stamped on
the side of the flowmeter body.
Material Cut-Off Module
If your gun is equipped with a material cut-off (MCO)
module, it can be disabled or enabled and configured to
extend and retract as the gun turns on and off.
Highlight the MCO Control prompt to enable or disable
the MCO module.
If you enable the MCO module, set the Extend Time and
Retract Time parameters. Extend Time delays the
extension of the MCO plunger for a period of time after
the gun turns on. Retract Time causes the plunger to
retract before the gun turns off. These delays are in
milliseconds. Enter Extend Time and Retract Time
delays from 0 to 500 msec.
DailyOperation
When the controller is powered on, it runs a self-test to
verify that it is operating properly. After the self-test is
complete, begin production operation.
1. Adjust any necessary production parameters from the
SET-UP screen.
2. Purge the gun to remove air from the material supply
hose and nozzle.
3. Set the bead size to the desired value.
4. Display the VOLUME screen to visually monitor the
time, Part ID, and bead size requested and achieved
for each part run.
5. Begin dispensing material from the robot controller.

Back Up Mode
If one of the following faults is detected, you may
continue production in Back Up mode with some sacrifice
to bead dispensing characteristics.
Gun Pressure Transducer
Upstream Pressure Transducer
Flowmeter
Flowmeter Cable
If one of these faults is detected, the HELP screen will
include a prompt to enter Back Up mode. When you
enter Back Up mode, the BACKUP MODE indicator on
the diagnostic panel lights and the alarm tower light shuts
off. You can continue production dispensing without
interruption.
Once the fault is corrected, the BACKUP MODE
indicator light shuts off after the next part is run or the
gun is purged.

Robot Signal Timing
You must adjust the timing sequence of output signals
from the robot controller to suit the Pro-Flo controller.
This is normally done during installation, but may need
readjusting occasionally. Please refer to your robot
controller manual for procedures to set the signal timing
sequences.
