Fan and Heater

OPERATING PROCEDURE

 

 

 

The limits are continuously checked during the drying operation. A limit switch open or any other er- ror condition will cause the dryer to shutdown, and the fan will be shut-

down. If a limit opens, or an er- ror condition occurs during dry- ing, the control will lockup in the error display mode. Power must be shut off and back on to the control to clear the error condi- tion--even if the error or limit that caused the shutdown has been corrected. This is to keep the display locked up with the condition that caused the error, allowing the operator time to determine what caused the shutdown.

Programming Set Points

Depressing the "PROGRAM" switch (lower left) causes the dis- play to enter the program mode. Each item below is programmed by using the up and down arrow switches. Holding down these up and down arrow switches for about 2 seconds will cause the numbers to increase/decrease rapidly until the switch is released. When finished programming an item, depressing the "PROGRAM" switch again will cause the new setting to be entered into memory, and the display will ad- vance to the next function to be pro- grammed.

Programming may be done at anytime (unless an error condi- tion exists) even while the dryer is in operation.

Programming a system with

Multiple heaters may be done at any heater control console. The informa- tion programmed is automatically transmitted to all other heaters when the programming is complete.

Hi Limit Set Point--The upper left cursor is flashing indicating the mode. If the plenum temperature increases above this point, the flame is shut off--"OFF-CYCLE" is displayed on screen.

Cycle Set Point--The upper 2nd from left cursor is flashing indicating the mode. If the dryer is not a hi-lo dryer, this function is skipped. If the plenum temperature increases above this point, the flame reduces to "LO-FLAME".

Humidity Set Point--The upper 2nd from right cursor is flashing indi- cating the mode. If the humidity is above this point the dryer operates normally--flame on and off at the high limit and cycle set points. If the humidity is below this point the dryer goes into the "OFF-CYCLE" mode.

Temperature Differential--The upper right cursor is flashing indicating the mode. If the flame shuts off because the temperature is greater than the high limit set point, the temperature must fall below the (Set Point minus Tem- perature Differential) for the flame to come back on.

Programming the high-limit set point.
