Make sure the process air filter is clean. Clean or replace if 
necessary.  
Make sure all the hose connections and all the components of 
the dryer have proper seals on them (i.e. desiccant tanks, heater 
box, filters, after-cooler). Tighten the connections and replace 
any damaged seals. 
Make sure the regeneration timing cycle matches the specs. If 
not, contact the Service Department.  

High Dew Point 

 
 

The dew point 
reading has 
exceeded the 
dew point alarm 
set point. 
 

Desiccant may be contaminated and blocking the air flow. Check 
desiccant, replace if necessary.  

- Process blower ON. 
- Process heaters ON. 
- Regen heaters ON. 
- Alarm Message ON. 
- Alarm horn is OFF. 

Make sure the process filter is clean. Clean or replace if 
necessary. 
Double check the alarm set point is at 35° F.  
Check the positioning of the thermocouple inside the air inlet of 
the drying hopper. The tip of the thermocouple should be 
centered in the tube, and not touching any metal part of the tube.  
The drying temperature set point is lower than dryer capabilities. 
Check the dryer specs.  
Make sure all the hose connections are tight.  

 

Process High 

Temp 

The process 
temperature 
has exceeded 
the alarm set 
point. 

Make sure the regeneration timing cycle matches the specs. If 
not, contact Service department.  

- Process blower OFF. 
- Process heaters OFF. 
- Regen heaters OFF. 
- Alarm light is ON. 
- Alarm horn is ON. 

Valve Positioning 

Fault 

The limit switch 
on the valve 
may not have 
been wired 
correctly. 

The switch is indicating the incorrect desiccant tank is in 
regeneration. Check the wiring of the switch against the wiring 
diagram. Make sure all the wire connections are tight. 

Limit switch may be out of position. Re-adjust the switch so it 
trips when it is at the high position, and avoids touching the cam 
when it is at the low position.  

 

Valve Motor 

Override 

The valve has 
made enough 
rotations and 
the correct 
position of the 
valve was not 
detected. 

Limit switch may be faulty. Replace the switch and make sure 
the wires are connected correctly.  

- Process blower OFF. 
- Process heaters OFF. 
- Regen heaters OFF. 
- Alarm light is ON. 
- Alarm horn is ON.
