Prime Screen Description -
The Prime screen displays the current Priming parameters and allows control of priming
operations. A user with Supervisor permission is able to change the parameters. The current permission level
determines which push-buttons are available as shown.
The Start and Stop push-buttons control Priming operation while this screen is visible.
Status -
The status indicates the operational state of the system. Refer to section 3.3.9 for an explanation of each
status type.
Volume Primed -
The Volume Primed line shows the total volume dispensed during the current or last priming
operation. This resets to zero at the start of a Priming operation.
Recipe -
The Recipe line shows the current recipe selected in the Recipe screen. "0" indicates values changed since
last "Get Recipe".
Pump -
The Pump line shows the current pump size selected in the Setup C screen. The pump size can be either 4A,
3A, 2A, 1A, B, C, D or NONE.
Prime Direction -
The Prime Direction is the direction of fluid flow through the Pump Module in Prime mode. The
direction is either Forward or Reverse. Forward is typically used to fill the tubing and pump with fluid. Reverse is
typically used to remove fluid from the tubing and pump.
Prime Volume -
The Prime Volume is the amount of fluid to move through the pump and tubing during a prime cycle.
Typically, this should be set to a volume greater than or equal to the volume of the pump and tubing. The range is
based on the pump size as shown in the Pump Minimum/Maximum Chart. The increment is equal to the minimum
volume for the selected pump size. Priming may be terminated early by pressing the Stop push-button.
Discharge Rate -
The Discharge Rate is the rate of the fluid movement in micro liters per second during the dispense
portion of a prime cycle. The range is based on the pump size as shown in the Pump Minimum/Maximum Chart. The
increment is equal to 20% of the minimum rate for the selected pump size.
Intake Rate -
The Intake Rate is the rate of the fluid movement during the load portion of the prime cycle in micro liters
per second. The range is based on the pump size as shown in the Pump Minimum/Maximum Chart. The increment is
equal to 20% of the minimum rate for the selected pump size.
