If the number you have entered does not match the IMPAX unit’s access code, the display will
show “ACCESS DENIED” for a few seconds, followed by the production counter. If the display
shows “LOAD STD PRGM?”, you have entered the correct access code, and you may now
check and/or modify the unit’s Channel Definition.
If you press Enter/Yes, the Default Channel Definition will be loaded for you to use as a starting
point in customization. Use caution however, because loading the Standard Program
permanently erases custom changes which were previously set into the IMPAX, and may be
difficult to reconstruct. If you press Next/No, the following steps will show you how the unit is
currently programmed.
The display will now say “DEFINE CHAN 1?”. If you wish to define Channel 1, press
Enter/Yes.
To operate on a different channel, press Back/Review or Next/No until that Channel Number is
displayed, then press Enter/Yes. There are sixteen channels, numbered 1 through 9 and A
through G.
These channels are software channels. All IMPAX monitors with Version 58 have sixteen
channels which means that you can define a sensor in more than one configuration. For
example, you can monitor the high limits on one channel and the low limits in a different
channel. There are many configurations which can be developed to make your IMPAX unit
better equipped to your particular machine and application.
When you have pressed Enter/Yes to select a channel, IMPAX will display “CHAN ENABLED”
or “CHAN DISABLED”. Press Next/No if you wish to change this, then press enter. If you
disable the channel, it will simply not exist in the operation. The channel definition program will
go on to the next channel number automatically.
If the channel is enabled, you must set up all of its operating parameters. The display will first
say “FORCE LINE - ”, asking which force sensor is to be assigned to that Channel. There may
be as many as 8 force sensors installed in the machine but only 1 can be selected for each
channel. Enter the number of the sensor you wish to select for this channel and the press
Enter/Yes.
The next display is “PEAK” or “INTEGRATE” ; this pertains to how the force measurement is
interpreted. When you select INTEGRATE, IMPAX will consider many observations during
each forming stroke. By considering all of the readings it establishes a number which represents
the total area under the curve. When you select PEAK, IMPAX will consider many observations
but will establish the number which represents the highest value in all of the readings. PEAK or
INTEGRATE may be selected by pressing Next/No, but should not be changed without good
reason. Press Enter/Yes to lock in your choice.
PTG/IMPAX recommends that INTEGRATE be used unless there are unusual circumstances
such as a very erratic reading from a sensor.
