1.  Turn the disconnect (if applicable) on the control panel to the ON position.  Power is 

applied to the voltage line fuses, line side of the control power switch. 

2.  Turn the control power switch to the ON position.  Power is applied to the 

temperature control, programmable relay and dew point controller.  The valve will 
move to the start position as follows: 

a.  The valve motor rotates until the cam switch makes 2 transitions.  

b.  If the cam switch does not make a transition within 10 seconds, a valve 

motor fault is generated.  “VALVE MTR” is displayed on the relay screen, 
the alarm light is activated.  The valve motor, heaters, and blower shut off.   

To restart the dryer, cycle control power to deactivate the alarm light and 
restart the valve motor sequence. 

c.  The valve will normally complete one full cycle (revolution). 

If the drying process shuts down due to an alarm, the dryer has been setup to 
have the following operational features: 

•  The bed in process at power-down will remain in process. 
•  The bed in regeneration at power-down will remain in regeneration. 
•  The regeneration timing cycle will restart from the beginning. 

3.  Once the control power is on and no fault conditions exist, the dryer will start as 

follows: 

a.  The process/regen blower is started. 

b.  The process heater is turned on and controlled by the E5CN controller. 

c.  The regen heater is turned on and the regeneration timing sequence is 

initiated. For default timing settings for regeneration, see the table below.
