If the LCD elements are incomplete dismantle the display and clean the zebra
elastomer and contact surfaces (see Section 4.13).
If the LCD is entirely blank check the power supply output voltages.
Confirm the power supply voltages conform to the table (see Section 3.1).
If the voltages are correct then check the fit of the EPROM into the socket. If this
does not correct the fault, then replace the processor PCB assembly. If the voltages
are not correct then replace the power supply assembly.
Alternatively the whole controller may be returned to the Kendall Service
Center for repair.
3.3 COMPRESSOR
If the compressor is not operating check that the controller is not in the standby
condition by pressing either the RUN . STOP Patient LEFT or the RUN . STOP
Patient RIGHT buttons.
Confirm the power supply for the compressor is at line voltage.
If the line voltage is correct then remove the compressor from the controller and
return it to the Kendall Service Center for a compressor exchange. If the line voltage
is not correct then replace the
power supply assembly .
Alternatively the whole controller may be returned to the Kendall Service
Center for repair.
3.4 IMPULSE CONTROL VALVES
If the controller is not impulsing air from either air hose socket, press both the RUN .
STOP Patient LEFT and the RUN . STOP Patient RIGHT buttons, check that the
LCD shows that the controller is impulsing and listen for air issuing from the patient
outlets. If air is not heard check the compressor performance (see Section 2.5.6).
Additionally the valve function can be checked by switching the controller OFF and
ON, and listening for the sequence of multiple clicks as the valves are cycled during
the start up routine.
If the clicks are not heard, check that the electrical connections to the valve driver
PCB assembly and from the valve driver PCB to the valve coils are secure. If the valves
still do not operate, disassemble the valves and clean them (see Section 4.8).
Alternatively the whole controller may be returned to the Kendall Service
Center for repair.
