This screen shows the time delay setting for the conveying blower on the MDC. This is the minimum time the MDC will wait before starting another load cycle.

This screen shows how the dryer is set to index the bedplates, on Time "tim"or Dewpoint "dew". To have the selection for indexing on Dewpoint, the PM1 option must be installed. By pressing the + or - keys, the setting can be changed. When the dryer is set to index on Dewpoint, it will index on time (20 min.) for the first 3 indexes so that the desiccant tanks have time to dry out. Then it will index on dew- point. The regeneration cycle will still be 20 min. If at the end of the 20 min. regen- eration cycle the process dewpoint is still below the setpoint the dryer will turn off the regeneration blower and heater and wait for the process dewpoint to reach its setpoint. If, however, the process dew- point stays below setpoint for 2 hrs., the dryer will index automatically.

This screen is the Setback Temperature Band screen. This temperature is the amount the return air out of the hopper has to drop below the activate setback temper- ature before the original process tempera- ture is restored. For example, if the acti- vate setback temperature was 180°F

(82.2°C) and the dryer was in setback. The actual temperature measured at the outlet to the hopper would have to drop below 160°F (71°C)to restore the original process setpoint.
