Page 14: User Groups
5.3 USER GROUPS The system contains four preloaded users (username and password sets) that are the factory (default) settings. Users can choose to use (or edit) these existing users or create new users as they see fit. Each of these default users has a different level of user rights to interact with the system based on their selected User Group. -
Page 15: Supply Air 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. -
Page 16: Application Settings
SECTION 7 APPLICATION SETTINGS Application settings are related to your spray application, and will allow you to customize the spray parameters to achieve the desired spray coverage and flow rates. These settings will also allow you to configure certain 1750+ accessories, such as the trigger interlock and remote duty cycle if they are included in your specific configuration in later chapters of the text. - Page 17 DISTANCE BASED SPRAY TIMING The fixed and variable spray length timing modes have an alternative in which distances are used instead of time. These modes are called fixed spray distance and variable spray distance. In these modes, delays are expressed in distance units.
- Page 18 PARAMETERS—ADVANCED NOZZLE SETTINGS For custom applications, it is possible to change the properties of the nozzle manually. These settings should only be modified by instruction from qualified SSCO personnel except for the nozzle cycle count. WARNING: Incorrect settings can permanently damage the spray nozzle! Negative Pulse: Pulse time in milliseconds •...
- Page 19 CYCLE SPEED The maximum frequency parameter (f ) 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.
-
Page 20: Recipe Settings
7.2 RECIPE SETTINGS Recipes are an optional feature that can be added with a fee to your 1750+. A recipe is a pre-configured set of parameters that allows you to change to a different production batch quickly. These parameters cover most of the timing and spray settings. -
Page 21: Spray Timing Modes
7.3 SPRAY TIMING MODES Timing modes are selected by going to the HMI settings page and selecting the “Timing” button. The system will spray for a predetermined time depending on the timing mode selected. The spray controller allows for accurate time-based control over the spray nozzle based on an external trigger signal. When there is a start delay value of 0 sec., the spray will start immediately after the trigger signal is sent to the 1750+, and if the stop delay is set to 0 sec. -
Page 22: Fixed Spray Time
7.4 FIXED SPRAY TIME This timing mode is used to create a delayed spray pulse for a fixed predetermined amount of time. The system will spray after a trigger, then stops until next trigger event occurs. For every trigger, there is a single spray event. Set parameter value to 0. - Page 23 SPECIAL CASE: MULTIPLE TRIGGERS WITH SPRAY OVERLAP Occurs if the system receives multiple start events (rising edge of trigger signal) before a spray cycle is finished. If the time delay between two successive start events (or trigger pulses) is lower than the spray time, then there is an overlap of two successive spray pulses.
-
Page 24: Variable Spray Time
7.5 VARIABLE SPRAY TIME The system will spray for a period based on the detected length of a product. Instead of entering a fixed spray period, an upper limit can be configured. The resulting spray period will be determined by the detection of the start and end of a trigger signal, with a fixed start and end delay. - Page 25 MULTIPLE TRIGGER EVENTS DURING SPRAY If the system receives multiple start events before the spray cycle is finished, they will be added to a queue and executed according to the given delay times. Variable spray period—multiple triggers OVERLAPPING SPRAY EVENTS If spray events overlap, the overlapping event will be ignored, and the system will continue to spray to ensure the objects are sprayed correctly.
- Page 26 OBJECTS TOO SMALL If spray events overlap, the overlapping event will be ignored, and the system will skip the small object. This situation may occur when the following is true: • Stop delay < Start delay • Object size < (start delay - stop delay) Variable spray period—small objects Variable Spray Period—Objects too small DISTANCE DELAY, MAXIMUM SPRAY PERIOD...
-
Page 27: Duty Cycle
7.6 DUTY CYCLE Duty cycle represents the ratio of the spraying "on" time to the "off" time, which results in some percentage of the maximum possible (continuous) flow through the nozzle. The duty cycle settings allow you to select the source and enter sensor default values. -
Page 28: Trigger
7.7 TRIGGER If you have an external trigger source, select the correct and corresponding option for your external trigger from the drop down list. Toggling the “Inverted” option to the On position will allow the use of a trigger that sends a signal when off rather than when on. -

Page 33: Diagnostics
SECTION 10 DIAGNOSTICS The diagnostics screen is a tool to help with system troubleshooting. This screen groups together real-time readings from connected digital and analog inputs and accessories and displays all of the read-only values in one location. These values can help to diagnose the cause of any faults. See Faults and Troubleshooting section for more information. - Page 34 HMI COMMUNICATION FAULT You will see small yellow triangles on the screen. Note this error occurs if the HMI is not communicating with the gun driver control board. Reboot the controller and if this does not fix the issue then consult with the factory. HMI communication fault FAULTS AND SOLUTIONS: ...
- Page 35 Controller will not operate spray nozzle. — Ensure that there is proper fluid pressure supplied to the nozzle. — Ensure that system is recognizing your trigger input. This is a common problem. If remote trigger/sensor is being used and button on the setup screen is set to “local”, the system cannot be recognized, the system trigger needs to be set to something other than “local”.
