Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING INTRINSIC SAFETY Intrinsically safe equipment that is installed improperly or connected to non-intrinsically safe equipment will create a hazardous condition and can cause fire, explosion, or electric shock. Follow local regulations and the following safety requirements. • Only models with model numbers 24F102-24F115, utilizing the air-driven alternator, are approved for installation in a Hazardous (explosive atmosphere) Location. See Models, page 3.
Warnings WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Important Two-Component Material Information Important Two-Component Material Information Isocyanate Conditions Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates. Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates. Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation in the work area.
Glossary of Terms Glossary of Terms Dose Size - the amount of resin (A) and catalyst (B) that is dispensed into an integrator. Potlife Time - the amount of time before a material becomes unsprayable. Dose Time Alarm - the amount of time that is allowed for a dose to occur before an alarm occurs. Potlife Volume - the amount of material that is required to move through the mix manifold, hose, and applicator before the potlife timer is reset. Dynamic Dosing - Component A dispenses constantly.
Overview Overview Usage The ProMix 2KE is an electronic two-component paint proportioner. It can blend most two-component paints. It is not for use with quick-setting paints (those with a pot life of less than 5 minutes). • Has dynamic dosing capabilities. It dispenses material A, monitors fluid flow, and dispenses material B in doses to cause the mixture to stay on ratio. • Can proportion at ratios from 0.1:1 to 30.0:1. • Will display the last 50 errors with date, time, and event.
Installation Intrinsically Safe Installation Requirements 1. The installation must meet the requirements of the National Electric Code, NFPA 70, Article 504 Resp., Article 505, and ANSI/ISA 12.06.01. Do not substitute or modify system components as this may impair intrinsic safety. For installation, maintenance, or operation instructions, read instruction manuals. Do not install equipment approved only for non-hazardous location in a hazardous location.

Installation Electrical Power Connection (non-IS units only) All electrical wiring must be completed by a qualified electrician and comply with all local codes and regulations. Line Enclose all cables routed in the spray booth and high traffic areas in conduit to prevent damage from paint, solvent, and traffic. The ProMix 2KE operates with 85-250 VAC, 50/60 Hz input power, with a maximum of 2 amp current draw. The power supply circuit must be protected with a 15 amp maximum circuit breaker.
Installation Grounding Air and Fluid Hoses Use grounded hoses only. The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit. Connect the ProMix 2KE ground wire to the ground screw. Connect the clamp to a true earth ground. If wall power is used to power controls, ground electrical connection according to local codes.

Basic Operation Basic Operation Pre-Operation Tasks Non-IS Systems (Wall Power Supplied): Turn the AC Power Switch ON (I = ON, 0 = OFF). Go through the Pre-Operation Checklist in Table 1. Table 1: Pre-Operation Checklist ✓ Checklist System grounded I = ON Verify all grounding connections were made. See Grounding, page 19. All connections tight and correct Verify all electrical, fluid, air, and system connections are tight and installed according to the manual instructions.
Basic Operation Prime the System 8. Open the fluid supply valve to the pump. NOTE: See Run Mode Details, pages 39-41, for further screen information, if needed. NOTE: If using an electrostatic gun, shut off the electrostatics before spraying. 9. If using a gun flush box, place the gun in the box 1. Adjust the main air pressure. Most applications require about 80 psi (552 kPa, 5.5 bar) air pressure to operate properly. Do not use less than 75 psi (517 kPa, 5.2 bar). 2.
Basic Operation Pump Calibration 6. Press NOTE: See Calibration 1 and 2 (Screens 22 and 23), page 46, for further screen information, if needed. to start the calibration on the checked pump (A or B). Press to cancel the calibration. 7. Trigger gun into a graduated cylinder. Dispense a minimum of 200-300cc of material. NOTE: Stop triggering the gun when desired amount is Calibrate the pump: • The first time the system is operated.
Basic Operation 10. After the volume for A or B is entered, the ProMix 2KE controller calculates the new pump factor and shows it on Calibration 1 (Screen 22) and Calibration 2 (Screen 23). If the fluid flow rate is too low: increase air pressure to component A and B fluid supplies or increase the regulated fluid pressure of mixed material. 11. Before you begin production, clear the system of solvent and prime it with material.
Basic Operation Purging Mixed Material There are times when you only want to purge the fluid manifold, such as: • • • • end of potlife breaks in spraying that exceed the potlife overnight shutdown or end of shift before servicing the fluid manifold assembly, hose or gun. 1. Press on Run Mix Spray (Screen 2) or from any screen to put the system in Standby. 9. Trigger the gun to relieve pressure. Engage trigger lock. 10. If spray tip was removed, reinstall it. 11.
Basic Operation 9. Reinstall the Control Box cover. 8. Purge as follows: • • • Purge component A side. Press the manual override on the Dose Valve A solenoid valve and trigger the gun into a grounded metal pail. Purge component B side. Press the manual override on the Dose Valve B solenoid valve and trigger the gun into a grounded metal pail until clean solvent flows from the gun. 10. Shut off the solvent fluid supply. 11.
Basic Operation Pressure Relief Procedure Power down and power back up again to clear the lock and put the new settings into effect. The lock ensures that the selection was intended and prevents the user from attempting to operate with incorrect settings. To reduce the risk of skin injection, relieve pressure when you stop spraying, before changing spray tips, and before cleaning, checking, or servicing equipment. NOTE: The following procedure relieves all fluid and air pressure in the ProMix 2KE system.
Use of Optional USB Module Use of Optional USB Module USB Logs Job Log 1 See example in FIG. 22. The job log records total volumes for each job that the system performs, up to 2000. It records the date, time, user number, job number, total A volume, total B volume, and mix ratio. Job total volumes are in cubic centimeters. A log entry is made when a new job is initiated, which occurs when batch totals are cleared, or when the job number is incremented from Run Job Number (Screen 38).

Setup Mode Details Dynamic Dosing In typical operation (ratios 1:1 and above), component A dispenses constantly. Component B dispenses intermittently in the necessary volume to attain the mix ratio. General Operating Cycle, Dynamic Dosing Overview Dynamic Dosing provides on-demand proportioning, eliminating the need for an integrator and therefore minimizing undesired material contact. This feature is especially useful with shear-sensitive and waterborne materials.

Error Code Indicator FIG. 54.
System Errors System Idle Warning (IDLE) This warning occurs if the ProMix is set to Mix , and 2 minutes have elapsed since the system last received the air flow switch signal (gun trigger). The Gun Idle icon is displayed. This warning is not active in systems with a 45:1 pump ratio, using an airless gun. In applications using the AFS, triggering the gun clears the warning and you can start spraying again. Without the AFS, triggering the gun does not clear the alarm.
