At power-up, the level is read
and indicates less than full.
Upon initiation of fill, two
"clicks" are heard. The
Control Module tries to fill (the
pump can be heard), but no
water is ingested. Pads are connected to
the patient lines,
preventing suction from
being applied to the fill
tube. Disconnect all pads.
At power-up, the level is read
and indicates less than full.
Upon initiation of fill, two
"clicks" are heard. The
Control Module tries to fill (the
pump can be heard), but no
water is ingested. Pads not
connected. Vacuum leak in a
patient line manifold
valve. See Low Water Flow.
At power-up, the level is read
and indicates less than full.
Upon initiation of fill, one or
no "clicks" are heard. The
Control Module tries to fill (the
pump can be heard), but no
water is ingested. Both the
BV and FILL LEDs on the I/O
Card illuminate. Bypass or Fill Valve
fault Check the I/O Manifold connector
at the I/O Card. Replace the I/O
Manifold assembly, if necessary.
Recalibrate upon completion.
Control Module will not fill
At power-up, the level is read
and indicates less than full.
Upon initiation of fill, one or
no "clicks" are heard. The
Control Module tries to fill (the
pump can be heard), but no
water is ingested. Only one
or neither of the BV and FILL
LEDs on the I/O Card
illuminate. Electronics fault. Call Medivance Service.
The probe and cable have not
been tested on another
Control Module. An open circuit exists
in either the probe or
cable. Replace the probe and cable in
turn, or try each on another
Control Module, to determine
which is at fault. Flex the cable
and probe, particularly near
connections to determine whether
there is an intermittent
connection. No patient temperature is
displayed even though a
probe is installed.
The probe and cable have
been shown to work on
another Control Module. Electronics fault. Call Medivance Service.
At power-up, no alarm occurs. The patient
temperature channel is
out of calibration. Calibrate the Control Module. A patient temperature is
displayed, but no probe is
installed.
At power-up, no alarm occurs.
Recalibration unsuccessful. Electronics fault Call Medivance Service.
The Control Module is
noisy. The noise is present at all
times and emanates from the
Power Module. A cooling fan is failing. Replace the Power Module.
