This screen shows status of the air pressure within the plenum, the status of the “Fuel Train Components” as well as the position of the “Modulating Motor” controlling fuel volume to the burner.
Here the Temperature and time setpoints are entered for operational limits of the burner. Any rectangular bordered box allows operational input. By clicking on the box you will view a pop-up calculator to enter set values.
Plenum Temp Setpoints
Minimum Temp Setpoint: is the minimum Plenum temperature allowed to be set by the operator.
Maximum Temp Setpoint: is the maximum Plenum temperature allowed to be set by the operator.
Maximum Plenum Shutdown Temp: is the maximum Plenum temperature set to be allowed by the controller which will result in a burner shutdown.
Plenum Temp Band
Over Band: is the maximum degrees over the set operational Plenum Temperature that the controller will allow before burner shutdown.
Under Temp Band: is the maximum degrees under the set operational Plenum Temperature that the controller will allow before burner shutdown.
Burner Time to Achieve Setpoint: is the time set for the burner to reach the operational set Plenum Temperature before burner shutdown. NOTE: Colder outside ambient temperature may require more gas pressure to achieve set plenum temperature. If inadequate gas pressure exist then burner potentially would never reach set Plenum Temperature. This timer will alert the operator of the condition.
Midgrain Temperature
Maximum Midgrain Temperature: is the Maximum grain temperature that is set to be allowed by the controller. This (RTD) Remote Thermal Device is located half way down the heat section of the dryer and imbedded in the column of grain to measure actual grain temperature.
High Midgrain Shutdown Timer- is the time allowed for the midgrain to be at or above the Maximum Midgrain Temp before burner shutdown.
Cooldown
Here you can select how you want to manage the cooldown time for the dryer. Operator can select for the controller to cool down to a set Grain Temperature or to cool down for a set time.
Cooldown Timer Setpoint: if time is chosen then the set time is entered in this window
Cooldown Temp: If Temperature is chosen then the set temperature is entered in the applicable pop-up window.
