Troubleshooting

See FIG. 4 and FIG. 5 to troubleshoot the 2KS and 3KS solenoids. Also see the System Electrical Schematic on
pages 24 and 26.

If the dispense or purge valves are not turning on or off correctly, it could be caused by one of the following.

Table 2: Solenoid Troubleshooting

Cause Solution

1. Air regulator pressure set too
high or too low.

2. Air or electrical lines damaged or
connections loose.

Check air pressure. 80-90 psi (550-630 kPa, 5.5-6.3 bar) is commonly used.
Do not go below 75 psi (0.5 MPa, 5.2 bar) or above 120 psi (0.8 MPa, 8 bar),

Visually inspect air and electrical lines for kinks, damage, or loose connec­tions. Service as needed.

3. Solenoid failure. Check the applicable solenoid’s LED (see F

with the following checks. If not lit, go to Cause 4.
Remove the connector for the applicable solenoid and measure voltage

across the pins on the board. If voltage is between 9-15 Vdc, replace the
solenoid.

Manually operate the valves by removing the color change module cover and
pressing and releasing solenoid valve override buttons. F

Valves should snap open and shut quickly. If the valves actuate slowly, it
could be caused by:

• Air pressure to the valve actuators is too low. See Cause 1.

• Solenoid is clogged. Make sure air supply has 10 micron filter installed.

• Something is restricting the solenoid or tubing. Check for air output from
air line for corresponding solenoid when valve is actuated. Clear restric­tion.

• A dose valve is turned in too far. See ProMix 3KS Operation manual for
settings,

• Fluid pressure is high and air pressure is low.

IG. 7 and Table 4). If lit, proceed

IG. 2.

4. Fluid station control board or
cable failure.

If there is no voltage across the pins on the board or it is less than 9 Vdc,
check LEDs D9 and D10 (see F

IG. 7 and Table 4). If both are lit and function-

ing properly, or other solenoids in the module are working properly, replace
the color change board.

If D9 and D10 are not lit:

• Check if the cable is disconnected or damaged.

• Check the fluid station control board (see the ProMix 2KS Repair-Parts
Manual).
