Resetting Limits after Power Failure
The MICRO2T records the location of all syringes when they stop. The information is
recalled the next time the MICRO2T powers up. This allows the instrument to resume
operation from the previous state without need to re-enter the syringe’s position. If the
MICRO2T is powered down while a volume delivery is taking place, the location at the
time where power is removed is not recorded. However, the MICRO2T detects that this
occurred and reminds you the next time the instrument is turned on. When you tap the
startup screen to begin operation, the warning appears.
Fig. 52—This warning displays if the controller loses power while a pump is running.
Press OK to continue operation. The message indicates which pump or pumps require
attention. Reset the end stop and syringe limits for the displayed pump or pumps. Until
the limits are reset, the message continues to display on power up.
To reset the end stop, see “Calibrating the MICRO2T System Travel Limits” on page 15.
Grouped Operations
Pumps may be grouped so that they start and stop together. Commanding any grouped
pump to Run initiates all the grouped pumps. However, the pump that is highlighted when
the run command is issued becomes the master pump. The other pump is a slave.
•
If the master pump reaches a mechanical limit before the delivery sequence
completes, then the master and the slave pump stop. A short, high pitch tone is
emitted when a mechanical limit is reached.
• If a slave pump reaches a mechanical limit, that slave pump stops, and the master
pump continues to run until it completes its sequence or until the master pump
reaches a mechanical limit.
1. Complete the operational preparations for each pump that will be grouped. Be sure
to set one of the pumps to Grouped so that they can run simultaneously. Grouped
pumps are marked on the Command screen.
