BAD PROBE
While in
AUTO CONTROL MODE
, if the patient probe indicates only a
direct short in the probe circuit this message occurs. As this message is
displayed, the trouble alarm sounds and the unit shuts down. This alarm
can be silenced using the SILENCE ALARM button. The operator then has
5 minutes to fix the probe. If after that time the condition has not been fixed,
the system will trouble alarm again, even though the SILENCE ALARM
button has been previously pressed. During this condition, the seven-
segment displays will both be blank.
While operating in
MANUAL CONTROL mode
, if a bad patient probe
develops, the heating/cooling system remains on, but the seven-segment
PATIENT display blanks.
While operating in the
MONITOR ONLY mode
, if a bad patient probe
develops,
the BAD PROBE message displays, the audible alarm sounds
and t
he “PATIENT” temperature display blanks. The audible alarm can be
silenced using the SILENCE ALARM button. The operator than has 5
minutes to fix the probe. If after that time the condition has not been fixed,
the system will trouble alarm again, even though the SILENCE ALARM
button has been previously pressed. Inserting a working probe in range
should clear the error message and return the unit to normal operation in
MONITOR ONLY mode
.
LOW WATER
This message occurs when the float switch senses that the water in the
reservoir is below a preset level or the float switch is defective. The trouble
alarm sounds, the seven-segment displays will be blank, the low water
symbol LED will flash, and the heater, compressor and pump will turn off.
The LCD display shall display the scrolling message “LOW WATER” for 5
seconds followed by “REPLENISH RESERVOIR” for 5 seconds followed
by “PRESS Δ TO CONTINUE” and scroll between them until the increment
key is pres
sed. The operator can silence this alarm using the “SILENCE
ALARM” button. The condition can also be satisfied if the operator adds
water to the reservoir and it reaches the proper level and the increment key
has been pressed to clear the scrolling ”LOW WATER” followed by
“PRESS Δ TO CONTINUE” message. Once the LOW WATER condition is
satisfied, the SETPOINT/ STATUS display changes to show CHECK
SETPT. The trouble alarm should still sound. In order to proceed, the
operator must once again go through the operating mode button sequence.
If the alarm is silenced, the operator has 5 minutes to add water. If after
that time the condition has not been cleared, the system will trouble alarm
again even though the SILENCE ALARM button has been previously
pressed.
LOW FLOW
This message is displayed when the flow out of the unit to a blanket is
reduced below 6 ± 3 GPH after an acceptable flow has been previously
detected. Along with this message, a trouble alarm will sound. The
operator can silence this alarm using the SILENCE ALARM button. The
operator has 5 minutes to fix the condition. If after that time the condition
has not been cleared, the system will trouble alarm again even though the
SILENCE ALARM button has been previously pressed. The condition can
also be satisfied if the flow increases above 6 ± 3 GPH.
CHECK FLOW SWITCH
This message will be displayed after the indicators are tested if the flow
switch is closed upon initial power up of the unit. This indication results
from a stuck flow switch. The audible alarm shall sound continuously for 30
seconds. After 30 seconds, the message will clear and the alarm will stop
sounding. Pressing the SILENCE ALARM key while the alarm is sounding
shall silence the alarm and clear the message. A unit with a bad flow switch
is still operable; however, a LOW FLOW alarm will not sound when flow
through the blanket is blocked.
