4-8 Setting the Shift on Dew Point

Our dehumidifying dryers shift air flow from the on-line desiccant bed to the regenerated desiccant bed, based on actual dew point demand, not fixed time cycles. After the off-line bed regenerates, the PLC controller waits for a high dew point signal from the process air dew point controller before switching beds. The PLC controller has a four (4) -hour timer override if it does not receive a signal from the dew point control.

„Set the shift on dew point set point to the highest process air moisture content you want to allow before the dryer shifts air flow to the regenerated desiccant bed. The dew point controller is set at the factory for -20ºF (-29ºC).

„To change the dew point setting, press the Up Arrow and Down Arrow buttons to the shift point you want.

4-9 Entering Operating Parameters to Select Modes

To enter the menu display:

1.Press the Display button for one second (keep the pressure on the button for about 1.5 to 2 seconds).

The screen displays .

2.Press the Up Arrow button to toggle through the different modes. The SV readout displays the mode you selected.

3.To switch parameters within a mode, press the Display button once more for about one and a half to two (1.5 to 2) seconds.

The PV readout displays the different parameters within each mode.

4.Use short presses on the Display button to display each parameter within a mode. The SV readout displays the different values for the parameter within a mode.

5.Press Up Arrow and Down Arrow buttons to set the higher or lower the values of a parameter.

6.Press Display button for about one and a half to two (1.5 to 2) seconds to move up a level back into the different modes.

7.Press Down Arrow button until Level 0 displays. Press the Display button for about one to one and a half (1 to 1.5) seconds to go to Operating mode.

4-10 Setting the High Dew Point Alarm

The high dew point alarm is factory set for -10ºF (-23ºC). The high dew point alarm will energize the “High Dew Point” light. Entering the Level 1 operating parameter changes the high dew point alarm setting. Use the following procedure to set the high dew point alarm:

1.Press and hold the Display button to access Level 0. The controller displays Level 0.

2.Press Up Arrow button to display Level 1. Lu-1 displays.

3.Press the Display button to select Level 1.

4.Press the Display button until the controller displays AL-1.
