The Bleimo brand of actuator is not responding to what is shown for percentage open on the plenums page on the HMI.
- At the terminals on the Bleimo, check for 24vdc between the red and black wires. Check for 0 to 10 vdc between the white and black wires. This voltage should correspond to the percentage of valve opening as shown on the plenums screen on the HMI.
- The actuator assembly might be bound up. Crack loose the single mounting screw found on the bottom of the box to allow the box and actuator to have a little movement.
- Tower dryers are equipped with drip legs. A drip leg is a vertical pipe, at the lowest level of the plumbing that terminates with a ball valve and a pipe cap. Remove the cap and open the valve to allow any accumulated water to drain out. Close the valve and replace the cap using approved plumbers tape or paste on the threads.
