•
If subsequent racks are run after the first rack has begun, the system will only run the same
program for the other racks.
•
The user must wait until a rack is picked up from the Load Station.
•
When a rack is already running and a new slide rack is inserted into the Load Station, the
software must determine the optimal schedule to run all racks simultaneously. This
processing may take several seconds so a "Please Wait..." message will appear on the screen.
Please note that the stainer will finish any current motions before the scheduling calculation
begins.
•
When a new slide rack is inserted and the stainer is in the middle of processing an existing
rack in a station marked as critical (Step Criticality=Yes), the scheduling of the new rack may
be delayed. Once the existing rack has exited the critical station the new rack will be
scheduled as usual.
•
Running multiple racks at the same time is more efficient than waiting until each rack is
completed before starting the next one. However there are situations when there is
insufficient time to process additional racks and not adversely affect the racks already in
progress. In those situations the new rack may not start processing immediately and its
processing may be delayed until the completion of the racks currently being processed. It is
recommended that each user analyze the set of steps that will be run and the desired
throughput to determine the maximize number of racks to run at one time.
•
The user should remove the processed racks as soon as possible to avoid delays and
extension of station times for the remainder of the racks.
•
The Compass Stainer can process up to four (4) racks simultaneously. It will not allow the
user to start a fifth rack while other four racks are being processed. The rack # on the display
will increment with each additional rack up to '4' and then return the counter to '1' if
subsequent racks are added.
To add another rack, the user has to place the new rack at the LOAD station, press the RUN key and
follow the prompts on the display.
