CARE SHOULD BE TAKEN THAT NO SOLUTION GETS INSIDE THE PUMP, AS DAMAGE
TO ELECTRICAL COMPONENTS COULD RESULT. PROLONGED EXPOSURE TO
ALCOHOL OR OTHER STRONG CLEANSERS COULD RESULT IN DAMAGE TO THE
PUMP HOUSING.
calibration
There is no calibration required for the Kangaroo Pet pump.
additional tests
Motor speed can be verified by measuring the time elapsed from when the motor starts
turning, stops, and then starts turning again.
Motor cycle time is as follows:
Time (seconds)
RATE (ml/hr) in backpack NOT in backpack
10
41.040
45.000
50 8.208 9.000
125 9.850 10.800
300 4.104 4.500
400 3.078 3.375
The tolerance for all cycle times is +/— 0.025 seconds when measuring with electronic
instruments. Manual stopwatch measurements are not recommended due to lack of
accuracy and consistency. A tolerance of -/— 0.25 seconds is allowed for-manual
measurement.
Pressing the CLR key while simultaneously turning the pump on with the ON key will result
in the pump’s language setting and software copyright and version number to be displayed
before normal operation begins. The language display text is shown in the language
selection portion of the circuit description of the ambulatory pump.
alarms
Internal Circuit Problem Alarm
The pump will alarm and display '8'8'8'8"” if an internal circuit failure has been detected.
The possible failures for this alarm are loss of microprocessor clock, failure to reset internal
microprocessor watchdog timer, disconnection of the battery pack, or an open or shorted
cell in the battery pack.
No Set Alarm
With no feeding set installed, the pump will alarm and display the “NO SET” message
when START/HOLD is pressed and the rate is not zero.
System Error Alarm .
The pump will alarm and display “SYS ERR” when the pump detects rotor movement when
the rotor is supposed to be stationary. A system error will also be generated if the rotor is
significantly slowed or stopped during a pumping cycle.
