KEYPAD FUNCTIONS BY KEY
(Cont’d)
MAN: The MANUAL key, a dual-function key which functions as a pause control when the
mill is in automatic mode, or as a manual override when the mill is in stop mode. Pushing this
key when the mill is stopped, or the liquid nitrogen level is too low for regular operation,
activates the coil for about three seconds. This brief running period can be used to test the coil:
place an empty vial with impactor in the coil, and if the coil is functioning, the typical rattling
noise will be heard for several seconds when the MAN button is pressed.
↓: DECREASE key. Can be used to decrease programmed values for impact frequency,
cycles, grinding time, cooling time, and pre-cooling time.
CYC: The CYCLE key is used to program the number of grinding + cooling periods per
grinding cycle.
T1: TIME 1 key, for programming the time of a grinding period.
T2: TIME 2 key, for programming the time of the cooling period between grinding periods.
T3: TIME 3 key, for programming the pre-cooling period prior to actual grinding.
1 through 0: These NUMERIC keys are used only in program mode, where in conjunction with
the CYC, T1, T2, and T3 keys they can be used to input the program settings. The INCREASE
(↑) and DECREASE (↓) buttons can also be used to increase or decrease program settings.
↑: INCREASE key. Can be used to increase programmed values for cycles, grinding time,
cooling time, pre-cooling time, and impact frequency.
ENT: Pressing the ENTER key locks current settings in temporary memory.
MULTIPLE-KEY FUNCTIONS
ENT + 0: STORE. When these keys are pressed simultaneously, the current program settings
are placed in permanent memory. (Display = “STO”)
Note: any newly entered program setting will displace the prior setting in temporary memory
when the ENT key is pushed. Temporary program settings are stored only as long as power to
the mill is on. When power is switched off and then on, the program will revert to the settings
in permanent memory.
Both temporary and permanent memories have room for only one set of numbers.
