Grain Systems PNEG-1935 - Manual (Page 47)

6. Moisture Control Options
PNEG-1935 Vision Hybrid for Portable Dryers 47
Setup Procedure
1. Press the “Stop” button on the control panel if the dryer is running.
2. From the “Setup” screen, select “Drying Mode”, then “Staged Batch”.
3. From the “Drying Mode Selection” screen, select “M/C Setup” to access “Staged Batch Setup”.
4. Select “Temperature” from the “Staged Batch Drying Criteria”. Make sure only the “Temperature”
check box is selected, as it is possible to have “Time” and “Temperature” selected at the same time.
If “Time” is selected, press the “Time” button to de-select it.
5. If desired, enable the “Max Time” safety.
6. Select “Single” or “Dual” plenum.
7. Return to the “Default Operation Screen”.
8. Press the “Temp” button.
9. Set the plenum(s) and grain temperature setpoint(s) to the preferred temperature(s).
10. Return to the “Default Operation Screen”.
11. Set the Cool Timer and Unload Timer to the desired time.
12. Position the “Unload” switch in the “AUTO” position.
13. Press the “Start” button on the control panel.
Time and Temperature Controlled Scheme
When to Use:
This scheme is used when the grain must heat for a minimum amount of time and must reach a desired
grain temperature.
How it Works:
The user should stabilize the dryer with the Unload switch in the “MANUAL” position. It is imperative that the
dryer is outputting the desired moisture content grain before switching the unload to the “AUTO” position.
Single Plenum: The user enters three (3) parameters: Dry Timer, Grain Temperature Setpoint and
Plenum Setpoint(s). The controller will remain in the drying phase at least as long as the Dry Timer. Once
the Dry Timer has expired, the controller will check the grain temperature sensor. It will remain in the drying
phase until the grain temperature setpoint is reached.
Dual Plenum: The user enters six (6) parameters: Hi-Heat timer, Lo-Heat timer, Hi-Temp, Lo-Temp,
Plenum Hi-Temp and Plenum Lo-Temp. The controller begins with the Plenum Hi-Temp as the plenum
setpoint and will remain there until both the Hi-Heat timer and grain Hi-Temp conditions are met. Plenum
Lo-Temp is then used for the remainder of the drying phase. The drying phase ends when the Lo-Heat
timer expires and the grain temperature exceeds the grain Lo-Temp setpoint.
Single and Dual Plenum: Two (2) safeties are available for this scheme: “Max Time” and “Max Grain
Temp”. By enabling this feature, the dryer will shutdown and issue a warning if the drying phase runs
longer than the “Max Time” period, or if the grain temperature exceeds the “Max Grain Temp” value.
