Applied Load Indicator reading during the “ Load Rising ” status. At
the very end of the piston travel the Applied Load Indicator value
rises almost instantaneously to the “ Pump up to ” load value and then
the “ Reached Piston Limit! ” message is displayed.
Note: This would be the similar to the fault condition “No Sample In the
Pressing Area” – see Section 7, page 68).
The “
Reached Piston Limit! ” message appears on the Display Screen
( 4 ) for a couple of seconds and then the press automatically releases
any pressure that has been applied from the press motor and pump
system indicated from the momentary Display Screen (
4 ) condition
showing the “ Piston Retract ” message in red text . (See Display
Screen step for Release of an Applied Load on page 33.) The Display
Screen (
4 ) will default back to the original start display condition for
any program ( PZ to P6 ) that has been loaded to apply, with an ( ok )
status and after a further period of circa 30 seconds to an ( OK )
condition status.
In effect, ANY program ( PZ to P6 ) that has been loaded and started to
be ( Run ) will be stopped with the release of any partially applied load
(oil pressure in the system), to leave the press in a safe condition when
a “
Reached Piston Limit! ” event has occurred and because the piston
travel has been reached. In such an instance, if the piston has reached
the limit of its travel for any previous pressing operation, it would be
best to start any new pressing application when the (
OK ) status
condition has been reached to allow for more (further) retraction of the
piston back to its start/rest position.
Two-Stage Pressing for Highly Compressible Samples
If a “
Reached Piston Limit! ” status has occurred because the sample
itself is highly compressible and the piston travel has been exceeded
before the “
Pump up to ” load to be set has been applied, any partial
oil pressure stored in the system will be released to allow the piston
face (
7 ) to retract.
