DRYER CONTROL PANEL
CONTROL POWER
SWITCH
The power to the Electronic Moni- toring Control System is turned on or off with this switch.
OUTSIDE LIGHT
The dryer service light is turned on or off here. It also may be set on auto, which turns the light on while the dryer is running and off if a shutdown occurs.
DRYING MODE SWITCH
This is used to select staged batch or continuous flow drying. The switch will light only after the Elec- tronic Monitoring Control System has been turned on, the safety cir- cuit is okay and the reset button on the control panel has been pressed.
LOAD AUGER SWITCH
This is used to select the opera- tion of the fill auger. In both the auto and manual position the load auger will operate if the dryer is low on grain and will automatically shut off when the dryer is full. In the auto position only, the dryer will shut down after a preset period of time set on the out of grain timer, or if grain flow is interrupted to the dryer. The switch will light when- ever the load auger is operating.
(Note: If the load auxiliary mo- tor overload relay is being utilized in the dryer control panel, this switch will also control the opera- tion of the auxiliary equipment).
FAN SWITCHES
Each fan is turned on or off with this switch. The on position oper- ates the fan continuously during staged batch and continuous flow modes. The auto position operates the fan in staged batch during the dry and cool cycle. The switch will light up whenever the airflow switch is sensing airflow and the dryer is full of grain.
HEATER SWITCHES
Each burner is turned on or off with this switch. The auto position op- erates the burner in staged batch during the dry cycle. The on posi- tion will operate the burner only when the fan is running. The switch will light up only when the flame sensor detects the flame.
UNLOAD SWITCH
The unload switch turns the meter- ing rolls and discharge auger on or off, and selects the operation of the metering rolls.
•In the 2 speed position if the moisture control switch is on, and the drying mode switch is turned to cont. flow, the metering roll speed will alternate between the high speed metering roll potentiometer setting and the low speedmeteringrollpotentiometerset- ting depending on the control signal from the moisture control thermo- stat. The discharge auger will oper- ate continuously.
•In the 1 speed position, if the mois-
ture control switch is on, and the dry ing mode switch is turned to cont. flow, the metering roll speed will op- erate at the high speed metering roll potentiometer setting or turn off de- pending on the control signal from the moisture control thermostat. The discharge auger will operate when ever the metering rolls are operating.
•In both the 1 speed or the 2 speed position, if the moisture control switch is off, and the drying mode switch is turned to cont. flow, the metering roll speed can be manu- ally controlled by adjusting the high speed metering roll potenti- ometer. The discharge auger will operate continuously.
•If the drying mode switch is turned to staged batch, the unload switch should be set to the 1 speed posi- tion. The discharge auger and metering rolls will only operate during the unload cycle of the staged batch operation, and the speed of the metering rolls is ad-
justed using the high speed me- tering roll potentiometer.
(Note: If the unload auxiliary motor overload relay is being uti- lized in the dryer control panel, this switch will also control the opera- tion of the auxiliary equipment.)
LOW SPEED METERING ROLL POTENTIOMETER
This is used to adjust the low speed of the metering roll when the 2 speed automatic moisture control feature of the dryer is in use.
