6.If the dryer has an aftercooler, make sure there is proper flow of cooling water flow through the coil, and any trapped air has been bled from the system.

7.Make sure the damper on the hopper air inlet tube is about 50% open.

8.Remove the lower end of the 2½" flex hose from the tube stub on the lower drying hopper. Carefully adjust the damper valve on the return line back to the filter to achieve approximately 200 cfm air flow out of the flex hose.

9.Set the process setpoint on the temperature controller.

10.After the proper pre-drying time for the initial hopper fill has elapsed, fully open the drying hopper slidegate.

To allow proper residence time during continuous processing, the material level in the hopper should be maintained at the midpoint of the air trap assembly.

5-3 Shutdown

•Turn off the conveying system supplying the drying hopper.

•When processing is complete, close the hopper slide gate and shut down any in-line companion equipment, i.e. an aftercooler.

•Push the Start/Stop button. After both blowers have shut down and regeneration is complete, turn the On/Off selector switch "OFF".

•Empty the drying hopper, if desired.

•For maintenance or long-term shut down, open (de-energize) the electrical disconnects at the dryer and in the power drop.

5-4 Setting the Process Air Temperature

To Change Process Air Temperature Set Point:

•

Press

to raise the Setpoint.

•Press to lower the Setpoint.

5-5 Setting the High and Low Temperature Alarms

To Change the Process Air High Temperature Alarm Setting:

1. Press for at least two seconds to access the level 1 parameters.

2. When the PV LED display shows

, use

and

to set the desired high

temperature alarm value.

 

 

 

The high temperature alarm value is a deviation of the process air temperature set point. The alarm value will track the set temperature. If the high temperature alarm is set to "25", a high temperature alarm occurs if the process air temperature rises more than 25°F above the process air temperature setpoint.

3. Press

until the PV LED shows

. Use

and

to set the desired low

temperature alarm value.
