5-2 Dryer Operation Procedures

Controller Operation (Without Optional Alarm Horn & Reset Button)

1.Turn the disconnect on the control panel to the ON position. Power is applied to the voltage line fuses, line side of the control power switch and the temperature controller.

2.Turn the control power switch to the ON position. Power is applied to the programmable relay and dew point controller. The valve will move to the start position as follows:

a.The bed switch 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. “VM” 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.

Note: The relay screen which contains the Alarm Display Messages is located inside the controller enclosure. For a list of Alarm Display Messages, see Page 39.

WARNING! Do not attempt to check the Alarms on the Controller located within the unit enclosure unless you are a qualified electrician!

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, turning the OFF-ON-START switch to the START position will start the dryer as follows:

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

b.The process & regen blowers are started.

c.The regen heater is turned on and the regeneration timing sequence is initiated. The regen heater is controlled by the E5CN controller. For default timing settings for regeneration, see the table below.

4.If either the left or right bed safety temperature switch opens, a regen heater fault is generated. “RS” is displayed on the relay screen. The alarm light is activated. The process heater, regen heater, and process/regen blowers are turned off.

Turn the OFF-ON-STARTswitch to the START position to deactivate the alarm light and restart the dryer. If either switch is still open, the dryer will not restart.
