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 SKIN INJECTION HAZARD Spray from the gun, leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury. • Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgical treatment. • Do not stop or deflect fluid leaks with you hand, body, glove, or rag.
Installation Installation Installing the Flow Meter • Flow volume can only be measured at the location where the flow meter is installed. Dust and Foreign Matter • Do not use more than 200 ft. (61 m) of cable. Avoid having dust or foreign matter enter the flow meter by taking the following precautions: • Refer to FIG. 1 to locate and install the flow meter, connectors, and fluid shutoff valves. Install a check valve to prevent backflow.
Installation Grounding 2. Never use the flow meter with an electrostatic gun isolation stand. Sensor Connector Pin-out 1. Always ground the fluid supply unit, using one of the following options: 4 a. Mount the meter to a grounded conductive surface, or b. Connect the conductive fluid hose to the meter inlet and outlet. c. Connect a ground wire to the meter’s M6 mounting holes.
Operation Operation Flow Meter Verification Pressure Relief Procedure 1. Turn off the fluid supply to the meter. 2. Shut off all electrical power to the fluid system. 3. Follow the Pressure Relief Procedure for your fluid system dispensing device. Flow Meter Function This is a positive displacement, gear flow meter. The gear flow meter is highly accurate, even with low flow rates. The fluid flowing through the meter rotates the gears. The gear position is monitored by a sensor device.
Troubleshooting Troubleshooting The sensor is not a serviceable part. Replace it if it is malfunctioning. Problem Cause No flow volume displayed at monitor- Flow volume is too low to measure ing unit Fluid is not flowing Fluid is not flowing Damaged cable Improper input voltage to sensor Damaged sensor Clogs in fluid line or in meter Gears worn or damaged 8 Solution Increase flow volume. See Problem: Fluid is not flowing, below. Replace cable. Make sure input power is 10-30 Vdc.
Maintenance Maintenance 4. Follow the Pressure Relief Procedure, then disconnect the fluid line from the solvent supply unit. 5. Reconnect the fluid line to the fluid supply. CAUTION Do not immerse the meter in solvent with the electronic sensor installed. Solvent could damage the electrical components. Air purge is not recommended for any gear-type flow meter. Air purges do not provide the lubrication the meter gears require.
Maintenance 5. Hold the end housing (1) and gently alternately tap on the two screws (2) with a hammer to separate the middle housing (11). 7. Insert the 3-tooth helical gear (8) into the gear bearing (5), making sure the two helical gears mesh with each other. 6. Remove the last two screws (2) and carefully separate the end (1) and middle housings (11) completely. 8. Line up the holes in the middle housing (11) with the helical gears, and carefully slide the housing over the gears. 7.
