Function Test
Pump's housing
Display and Barleds
Check that all parts are in place. Clean with an agent listed on pg.
Switch the pump on, check that all display segments and all
barleds are on during the initialization test, check that all numbers
on the display appear sequentially on all 4 seven segment
display.
AC icon
Connect the pump to mains, the AC icon shall appear on the
display. Disconnect the pump from mains. Check that the AC icon
disappears. When the pump is battery operated the numbers on
the display will flush.
Air sensor
Load a primed administration set into the pump. Use an
oscilloscope. On JP8 P4 should be a pulse greater than 3.8v.
(pick to pick).
Load a set with air. On JP8 P4 should be a pulse smaller than
0.8v (pick to pick).
Load a stiff tube with air into the pump. Check on the testing
connector JP8 P5 pulse is smaller than 0.8v.
In case that the pulse pick to pick on JP8 P5 is greater than 1v,
use the potentiometer P1 to reduce amplifier.
Check pulse on JP3 P5 if the current is more than 180 MV. If less
replaced sensor.
Check on JP8 P4 if zero level is less than 0.8v continuously 1
msec.
Motor sensors
Check, using oscilloscope, motor sensor channel 1 on JP8 P2.
Rotate manually the encoder and check the sensor in position 1
and zero.
Check motor sensor channel 2, same procedure as above, on
JP8 P3.
Input 5v
Switch pump on. Check using an avometer the voltage on JP8
P7. The allowed values are between 4.9 to 5.1v.
12V Input
Check on JP8 P8 the 12v input. Values allowed are 11.5 to 12.5v.
