Secondary Control Panel
The secondary control panel (Figure 3-1) is located on the lower right side of the
COBE 2991 and is accessible by opening the right panel door. The secondary
control panel has the following controls:
• PUMP RESTORE RATE control (in mL/min)
• CB1 through CB5 circuit breakers
• AUDIBLE ALARM ON/OFF switch
• RED CELL OVERRIDE control (in seconds)

PUMP RESTORE RATE (in mL/min)
The PUMP RESTORE RATE control sets the rate at which the hydraulic pump is
driven in the reverse (downward) direction to its home (starting) position. The
hydraulic pump returns to its home position during the Agitate/Wash-In operation,
or after the STOP RESET button is pressed (if the pump is not already in its home
position). This can affect the minimum agitate time, because the COBE 2991 will
not advance from the Agitate/Wash-In operation until the hydraulic pump is at its
home position. On COBE 2991s, serial numbers 2000 and above, the rate is
adjustable between 0 and 700 mL/min. On COBE 2991s, serial numbers lower
than 2000, the rate is adjustable between 0 and 450 mL/min.
Warning:
Only trained
technical
personnel
should open the front and
right panel doors. Only
qualified service personnel
should open the left and
rear panel doors. A special
tool may be required to
open the panel doors.
