Piston Travel
There is a maximum piston travel of 24mm and the press motor and
pump will automatically stop when this travel limit is reached. An error
message “
Reached Piston Limit! “ in red text will be momentarily
illuminated as an indicator for the status when a program is running.
Important! If at all possible it is desirable to avoid
running the press piston to the limit of its travel .
In an example (
MOS ) Display Screen ( 4 ) message as shown above, a
custom program ( P4 ) has been created for specific pressing and load
hold time steps. (The first four segment steps ( S1 to S4 ) of the
program are shown. The program has been loaded and started running
after pressing of the start button (
11 ) for the first segment ( S1 ) step.
(“ Pump up to” 15 Tons .) This condition and message status of the
press has been reached because the piston has travelled to its full limit
before the “
Pump up to ” load has been obtained; to be set and
maintained for 0.3 minutes for this specific program sequence.
When using highly compressible samples in an evacuable pellet die, it
may be possible for the maximum travel of the piston to be reached
before the desired “
Pump up to ” load has been applied to compress
the sample accordingly within the die. Usually for this condition to
occur, such that the piston of the press has reached its maximum limit
of travel, will be evident by little or no load being indicated at the
