SECTION 3
1750+ OVERVIEW
The AutoJet® 1750+ Spray Control System featuring an HMI Touch Screen Display is a self-contained, electronic/
pneumac panel that provides control of various aspects of a spray system. These systems come in a variety of design
conguraons depending on the requirements of your spray applicaon, therefore, you may or may not have all the
features described in this owner’s manual.
3.1 FEATURES
The Spraying Systems Co.® AutoJet 1750+ Spray Control System is a self-contained unit that can provide you with
precise liquid delivery and spray nozzle control in an aordable easy to use turn-key spray system. The system comes in
a variety of designs and conguraons based on the type of spray nozzle used in your applicaon.
The system can be used with water, oils, lubricants, inks, stains, water-based solvents, and non-abrasive slurries. The
system is designed to spray most non-ammable or non-volale materials. Liquids and materials that ow with
viscosies below 1000 cP at 68°F (20°C) can be sprayed with the correct spray nozzle and controlled with this unique
spray system soluon.
SYSTEM USAGE
• The AutoJet 1750+ Spray Control System is designed to run connuously or intermiently.
• The AutoJet 1750+ Spray Control System features a high-quality HMI touchscreen interface.
— The user can set and control dierent spray ming such as; spray period, start delay, and stop delay mes.
• The controller is designed to run both electric and air actuated spray nozzles.
— Can drive Spraying Systems Co. electric-actuated spray nozzles (3.6 amps. max.) with Pulse Width Modulaon
(PWM). Specically, the PulsaJet® spray nozzle line and the AA250AUH Electric spray nozzles can be used.
— PWM (Pulse Width Modulaon) is a technique used to control ow rate by rapidly pulsing the nozzle on and o
and uses a duty cycle within the spray me. Duty Cycle (DC) is the percent of me of the total cycle me the
nozzle is spraying. If the nozzle is spraying 50% of the me, the DC is 50% thus the ow is ½ that of the nozzle
being fully open.

PRECISION SPRAY CONTROL (PSC)
The PulsaJet® automac spray nozzle is an electrically-acvated hydraulic, atomizing nozzle. This nozzle sprays the
product in a controlled way using a PWM algorithm to control the sprayed amount without aecng the spray angle.
PWM is the fundamental control principle that allows a signicant reducon in ow by regulang the relaonship
between the on/o mes that the nozzle operates.
Short pulses of on-me and longer pulses of o-me produce a spray paern that appears connuous, but actually
reduces the overall ow delivered to the target surface. This provides beer ow control with larger spray ps that are
less prone to clogging. The droplet size is aected by the pressure of the liquid. With PSC, the droplet size and spray
angle are independent of the liquid ow because the nozzle can work at the same liquid pressure for variable liquid
ows.
PSC involves switching the spray nozzle on and o repeatedly at a controlled rate, called the modulang frequency.
The modulang frequency is the number of mes the nozzle is switched on and o in one second and is measured in
Hertz (Hz). If a spray nozzle is switched on and o 10 mes per second, the modulang frequency is 10 Hz. The me
from when the nozzle turns on to the next me the nozzle turns on is called the period, in this case 1/10th of a second.
Within a single period, the nozzle is switched on, then o. The me that the nozzle is on, divided by the total me of
the period, gives a percentage which is called the duty cycle. For example, if the period is 0.10 seconds, and the nozzle
is on for half of that me, then the duty cycle is 50%. For the same period, if
the nozzle is on for 0.08 seconds then the duty cycle is 80%. Therefore, at an
80% duty cycle, the ow will theorecally be 80% of the maximum ow rate
(= 100% ow rate) at a given pressure for the nozzle. Using PSC, the ow rate
for a spray applicaon can be easily controlled without the need to adjust the
spray pressure or spray p.

5.3 USER GROUPS
The system contains four preloaded users (username and password sets) that are the factory (default) sengs. Users
can choose to use (or edit) these exisng users or create new users as they see t.
Each of these default users has a dierent level of user rights to interact with the system based on their selected User
Group. It is very important to pay close aenon to the selected User Group for each current and created user. The
table below shows the factory default users, user groups, and user rights. The minimum password length for all user
groups is four (4) characters, and all user groups have access to basic spray control panel features.
USER GROUP:
Operators
These users can trigger the system and put it in standby mode. Operators can change the duty cycle setpoint. All other
funcons are disabled or read-only for users in the operator user group.
• The factory sengs user “operator” is a member of this user group.
Cust_admin
These users have full control over all system sengs and can edit or create new users.
• The factory sengs user “admin” is a member of this user group.
Admin
There is a fourth factory sengs user “SSCO” that is included with the system in User Group admin.
This user is included as a backup opon to reset User Group cust_admin passwords if they are lost.
Do not use the “SSCO” user for daily operaon of the unit. User Group admin and User Group cust_admin have the
exact same access rights.
ATTENTION: A system restart is required to apply any changes made to user sengs.
DEFAULT USERNAME:
Inial startup and all reboots of the system will load into the factory sengs “default” user prole.
Under factory sengs, the user “default” is within the user group default, which has the exact same level of access as
user group cust_admin.
• With factory sengs, this user has full control over the system and can edit or create new users.
• Users can edit this user to change its access level.
• Can be changed to user group “operator” to remove edit access.
• Can set an Inacvity logo me to require someone using the system to log in with their personal credenals aer
a set period of me.

SUPPLY AIR TO THE SYSTEM
6.1 ADJUSTMENTS AND OPERATIONS
1. Turn the red valve on the air inlet valve/regulator/lter clockwise to the on posion. Turn regulator that is on top of
the air lter to an air pressure between 40-100 psi (2.8-6.9 bar). Air pressures higher than this will shorten the life
of the pump.
2. Adjust the regulated air pressures (regulators on front panel).
• If applicable, depending on your spray system you may have anywhere from Liquid Pressure regulaon only to
Liquid Pressure; Pump Air (preset); Atomizing Air (drop size); Fan Air (spray angle/paern).
 Each air control line is equipped with a manual air pressure regulator. The regulators can be adjusted by rst pulling
up on the knob to unlock the regulator and then turning clockwise to increase and counterclockwise to decrease
the pressure.
 When the proper air pressure is reached, press down on the knob on the regulator to lock it in place.
Note: Your system is equipped with cylinder air for air actuated spray nozzles. Cylinder air pressure is equal to the
inlet air pressure to the system. It is not regulated; therefore, you must provide a minimum of 45 psi (3.1 bar) to the
system. It must be above 45 psi (3.1 bar) to actuate air actuated nozzles like Spraying Systems Co.® 1/4JAU series.
5. Adjust the Liquid Pressure regulator. For pump version ensure that the pump inlet air valve is in the “open”
posion. The regulator can be adjusted by rst pulling up on the knob and then turning clockwise to increase and
counterclockwise to decrease the pressure. When the proper liquid pressure is reached, press down on the knob to
lock it in place.

Applicaon sengs are related to your spray applicaon, and will allow you to customize the spray parameters to
achieve the desired spray coverage and ow rates. These sengs will also allow you to congure certain 1750+
accessories, such as the trigger interlock and remote duty cycle if they are included in your specic conguraon in
later chapters of the text. This Applicaon Sengs secon explains the Spray Nozzle Sengs, Conguraon, Duty
Cycle, Trigger, and Tank Level Sensor Sengs.
Note: Applicaon Sengs and Recipe Sengs are the same. Use recipe funcon to congure most sengs if the recipe
feature is included in your system conguraon.

DISTANCE BASED SPRAY TIMING
The xed and variable spray length ming modes have an alternave in which distances are used instead of me.
These modes are called xed spray distance and variable spray distance. In these modes, delays are expressed in
distance units. These are the units that were chosen when calibrang the frequency input.
The ancipator me in this mode has a special behavior, it is converted to a distance using the maximum speed,
meaning that it is a minimum ancipator me. At speeds below the maximum speed, it will be longer.
ANTICIPATOR/FOLLOWER TIME
The system will start spraying when it receives a “trigger” signal and stop when the trigger signal is removed.
If your system is equipped with an air atomizing nozzle the 1750+ will switch the air output on before it starts spraying
to allow the spray paern to develop fully. When the system stops spraying, the air will connue for a short period
aer to guarantee no large droplets can drip o of the nozzle. These mes always reference from the spray ming.
Max me for both is 10 s.
Note: The ancipator me must not be shorter than the start delay me set in the ming sengs.
When a spray paern is generated where the o me < (ancipator me + follower me), the air output remains on
for the duraon of this paern.

PARAMETERS—ADVANCED NOZZLE SETTINGS
For custom applicaons, it is possible to change the properes of the nozzle manually. These sengs should only be
modied by instrucon from qualied SSCO personnel except for the nozzle cycle count.
WARNING: Incorrect sengs can permanently damage the spray nozzle!
Negave Pulse: Pulse me in milliseconds
• Used to speed up the closing of the electric spray nozzle, duraon is dependent on nozzle model and supply volt-
age.
Gun (Nozzle) Oset: Oset me in milliseconds
• The dierence in the opening and closing me of the PulsaJet nozzle can be corrected by using the oset value.
The default value is 0ms. For example: If the oset value is set to -1ms, the on period will be decreased by 1ms
and the o period will be increased by 1ms.
If a nozzle wear cycle count alarm has been acvated, the counter must be reset in this screen aer the nozzle has
been replaced.

CYCLE SPEED
The maximum frequency parameter (fmax ) determines the maximum speed of the nozzle at 50% duty cycle and is
entered as a number of cycles/minute. This parameter can be found in the datasheet of the electric spray nozzle being
used.
The spray control panel will calculate the cycle speed to conform to the following requirements (in this order):
• As slow as possible to prevent wear of the spray nozzle.
• Correct duty cycle this means ON-me / (ON-me + OFF-me) = duty cycle.
• OFF me lower or equal than the maximum on/o me parameter. This prevents striping and very low
frequencies at low duty cycles.
• ON me lower or equal than the maximum on/o me parameter. This prevents striping and very low frequencies
at high duty cycles.
• Frequency of the signal higher than the PWM minimum cycles/min seng. This can be used to keep the frequency
constant for a large range of duty cycles.
• ON and OFF me higher than or equal to the minimum pulse width of the gun. This ensures that the nozzle is able
to open and close at the same speed as the signal.
Cycle speed sengs allows for the eding of the minimum and maximum cycles per minute, as well as the spray
thickness. Maximum cycles speed is 7,500 cycles/min, minimum range is 0-60 cycles/min.
• Maximum cycle speed: Maximum speed that the nozzle should switch at for this applicaon. This entry will be
limited by the type of nozzle selected.
• Minimum cycle speed: Minimum cycle speed for the 1750+ is recommended for this applicaon.
Note: If you want a constant cycle speed, enter a large spray thickness, and use the minimum cycle speed as your
required cycle speed entry. The 1750+ will then cycle at this speed whenever possible.
Cycle Speed Example:
For a nozzle that can achieve 10,000 cycles/min, the minimum pulse width is 3ms. This ensures that the combinaon
of duty cycle and cycle speed falls within the triangle curve of the PulsaJet® electric spray nozzles (See gure below).
The triangle is the approximate operang range of the nozzle. As long as operang parameters (duty cycle and
frequency) are inside this triangle, the nozzle will operate normally. If the operang parameters are outside the
triangle, the nozzle will not operate.
Example:
Spray Nozzle: AAB10000AUH-03
• Maximum cycle speed: 10000 cycles/min
• Minimum cycle speed: 0 cycles/min (= disabled)
• Minimum pulse width: 3ms
Objecve:
• Maximum on/o me: 0.010 s or 10ms
• Duty cycle: 30%

7.2 RECIPE SETTINGS
Recipes are an oponal feature that can be added with a fee to your 1750+. A recipe is a pre-congured set of
parameters that allows you to change to a dierent producon batch quickly. These parameters cover most of the
ming and spray sengs. Recipes can be accessed quickly from any screen by selecng the recipe secon of the top
bar, as shown in the image below.
The recipe sengs secons contains four tabs. The drop down list near the top of the page allows you to select which
recipe you would like to view, edit, or apply as the current spray parameters. The 1750+ is capable of storing up to 20
user-created recipes.
GENERAL TAB IN RECIPES
You can change the name of the recipe and create a recipe descripon using the blue pencil icon. This can allow
operators to easily dierenate between dierent recipes when changing spray parameters is required.
