Troubleshooting

NOTE: Check all possible remedies before disassembling the system.

Color Change Solenoid Valves

NOTE: Refer to Electrical Schematics, page 36. If the color change valves are not turning on or off correctly, it could be caused by one of the following.

Cause

Solution

 

 

1. Air regulator pressure

Check that air pressure is at least 85 psi (0.6 MPa, 6.0 bar). Do not go above 100

set too high or too low.

psi (0.7 MPa, 7.0 bar).

2. Air or electrical lines

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

Service or replace as needed.

are loose.

 

3. Solenoid failure.

Check the applicable solenoid’s LED; see Color Change Board, page 34. If lit,

 

proceed 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:

 

• In a non-hazardous location, replace the solenoid if voltage is 24 Vdc.

 

• In a hazardous location, replace the solenoid if voltage is between 9–15 Vdc.

 

Test the valves as explained under Maintenance Screen 4 in your PD2K

 

Operation manual. Valves should open and close 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 the air supply has a 5 micron filter installed.

 

• Something is restricting the solenoid or tubing. Check for air output from the

 

air line for the corresponding solenoid when the valve is actuated. Clear the

 

restriction.
