Manual Compaction
The manual compaction keys allow the user increased flexibility.
With manual compaction, the user can start each phase of the
compaction process with a single, specific keypress. The control
unit beeps twice before starting any motion.
The two LED displays show the specimen height (updated each
revolution) and number of gyrations remaining. The lights beside
the manual compaction keys and the control unit screen show the
compaction progress. After each phase, the light beside the next
logical manual compaction key blinks.
Check that the notch on the mold handle is at 6 o'clock. With a
loaded mold properly in the chamber, close the chamber door.
The first phase is lowering the ram. Press 〈RAM DOWN〉.
After beeping twice, the unit lowers the ram. If the mold notch is
not aligned with the pin after the unit begins lowering the loading
head, then press 〈STOP〉, open the chamber door, align the mold,
close the door, and press 〈RAM DOWN〉. If the loading head hits
the top of the mold, the control unit will display the error and the
loading head will retract. Open the chamber door, center the loading
head, close the chamber door, and press 〈RAM DOWN〉 to resume
compaction.
Remember that after completing each compaction phase, the light
beside the next typical compaction key blinks.
When the ANGLE ON light flashes, induce the angle of gyration by
pressing 〈ANGLE ON〉. The unit beeps twice and induces the angle
of gyration.
When the GYRATION ON light flashes, begin gyration by pressing
〈GYRATION ON〉. The unit will beep twice and begin gyratory
compaction.
After the unit completes the full number of gyrations, the ANGLE
OFF light flashes. Remove the angle of gyration by pressing
〈ANGLE OFF〉. The unit will beep twice before moving.
