D-Tec Vaporizer
August 2001
O & M Manual Part No. 1107-0622-000
3.3.4
Low Agent Level
The amber LOW AGENT light flashes accompanied by a
long tone operation of the auditory alarm which is a
repetitive 1.5 seconds ON and 0.5 seconds OFF. The
alarm indicates that there is less than 60 ml of agent
remaining in the sump.
Pressing the
mutes the auditory alarm for a period of 120
seconds to allow time to fill the vaporizer to above 60 ml.
If a LOW AGENT condition occurs during normal
operation, the alarm is activated but the green
OPERATIONAL light remains illuminated.

No Output
The NO OUTPUT alarm is activated if any one of the
following occurs:
1.
The agent level decreases to below 20 ml.
2.
The vaporizer is tilted.
3.
A power failure of longer than 10 seconds duration occurs.
4.
An internal malfunction is detected.
The alarm consists of a flashing red NO OUTPUT light
accompanied by short tone operation of the auditory alarm
which is a repetitive 0.5 seconds ON and 0.5 seconds OFF.
The alarm indicates that the vaporizer has closed down and
is no longer delivering any vapor.
Fig. 8 No Output
If the NO OUTPUT alarm occurs while the vaporizer is in use, the vaporizer dial must be turned to
q
. This
mutes the auditory alarm and illuminates the red light continuously. Either an alternative vaporizer or an
alternative method of anesthesia must be used.
If the NO OUTPUT alarm is activated as a result of a power failure and
the dial is at
q
when the power supply is restored, the alarm and
display test is activated and then the vaporizer returns to either the
WARM-UP or the OPERATIONAL mode.
If the dial is not at
q
when the power supply is restored, the NO
OUTPUT alarm continues and can only be cancelled by turning the dial
to
q
. In this condition the alarm and display test is not activated and
the vaporizer returns to either the WARM-UP or the OPERATIONAL
mode after a 10 second delay.
3.3.6
Alarm Battery Low
The amber ALARM BATTERY LOW light continuously illuminates to
indicate that the alarm battery voltage is low. A new battery must be
fitted within eight hours to support the NO OUTPUT alarm in the
event of a subsequent mains failure condition. There is no auditory
alarm in the ALARM BATTERY LOW condition.
