Figure 4.7 - Operating Schedule: Fixed Cycle
Notes:
Shaded areas show when a given input or output device is energized. Input and output devices are described in Figure 4.6.
If the dryer has two stage regeneration (optional), input I1.0 will always be on.
If the dryer is equipped with the demand cycle option, input I0.7 will always be on.
If the dryer is equipped with the demand cycle option, output Q2.1 will be on when the right tower is drying.
Descriptions of each step are given in Figure 4.9; alarms are described in Figure 4.10.
If the dryer has one stage regeneration (standard), the program will skip steps 10 through 13.
