TROUBLESHOOTING

Review the symptoms below for operating difficulties. With each problem there are one or more possible causes to investigate.

NOTHING HAPPENS - If absolutely nothing happens when trying to cycle the Dispense Valve, check the electric and pneumatic power. Check the foot switch or cycle start switch for proper connection.

HEAD CYCLES, NOTHING DISPENSED - (1) Check to see that there is enough air pressure to the reservoir, and to the Dispense Valve 70 psi (4.8 bar). - (2) Check to see that the Stroke Adjustment Collar (1 in the illustration) cycles properly. - (3) Perhaps material has “set up” in the reservoir or needle path; examine and clear or replace as necessary. - (4) An air bubble could be near the check valve. Cover the check-valve end with fingertip and cycle; or point check-valve end UP and cycle. - (5) Remove the check valve and inspect the seat and spring.

IRREGULAR VOLUME DISPENSED - Faulty material will cause irregular dispensing. The material must be a smooth (homogeneous) mixture, without any air trapped in it. A second cause could possibly be that the material is not filling the metering rod chamber fully and in time. Check the reservoir pressure; it may be too low for the type of material being dispensed and/or the cycle time may be too fast. Cycle time is a function of the air supply controller. To adjust, follow the directions found in the controller operating manual.

SLOW OR SLUGGISH CYCLE TIME - This may be due to inadequate lubrication of the piston walls. Refer to the Periodic Maintenance section of this manual.

HEAD DROOLS OR OOZES - This can result from air trapped in the material being dispensed, or worn seals. First, check the valve seals for excessive wear. Seal kits are available and the proper kit for your valve is noted on the assembly drawing. Refer to the Periodic Maintenance section of this manual.

NOTE: If this is a .188 inch rod diameter valve, be sure that the plastic washer and o-ring above the outlet check valve is firmly seated.

DISPENSE VALVE LOCKS UP - First, check to see that you are using unlubricated air; It is possible for oil to build up in the valve piston when using lubricated air. Refer to the Periodic Maintenance section of this manual.
