Pressure display - calibration mode
If the pump is operating on AC mains supply, the pressure
transducer on the front door assembly sensor may be calibrated, so
you see this parameter:
A B C D
The bottom line of this screen shows four fields, marked on the above
example as A, B, C and D. They are described in the table below:
Field Range Comment
A 0 to 1919 Represents motor position. It shows ‘unref’ if
unref the motor cam position is unreferenced. It shows
or * * in the first position if a motor stall was detected.
B 0 to 1919 Represents the position immediately before the
last motor “home” position realignment. If there is
no significant motor slippage, expected display
values are between 0 and 40 or 1880 and 1919.
C 0 to 255 Raw analog-to-digital pressure reading from the
display board. This value is read and the Message
Display value updated at least twice per second.
This permits occlusion alarm calibration to a
known pressure by adjusting two potentiometers,
see Occlusion alarm adjustment on page 8-15..
D 1, 0 or
-
Represents the pressure plate position
switch, where:
1 = cassette-in-position
0 = no cassette present
- = communication error when switch
is read.
Pressure transducer calibration screen
The default rate is 25 mL/h. To adjust the rate:
• Press Rate and enter a rate with the number keys. The run light
flashes whenever a rate can be entered using number keys.
To accept the entered rate:
• Press Run . The rate appears in the rate display.
To toggle the motor direction:
• Press Primary . If the motor is running backwards, the pumping
indicator shows a minus sign. If the motor is running (forward or
backward) the run light is continuously lit.
To stop the motor.
• Press Hold . When the motor stops the hold light is lit.
