Alarms
The Model 3960 Series incubator is equipped with a system which notifies
the user of an alarm condition inside the incubator. All alarms are
displayed in the control panel message center. The following table contains
information on all possible systems alarms.
To avoid alarms going off in day-to-day use, some alarms are equipped
with a time-delay feature. For this to function correctly, the alarm
condition must exist for the specified length of time before the message
center will display the alarm. This allows for interruptions, such as door
openings, to occur without the incubator going into a continuous state of
alarm.
When an alarm condition exists, the Silence key can be pressed to
temporarily mute the audible alarm. The message center will continue to
show the alarm condition. If the alarm condition is not corrected within a
specified length of time, the alarm will sound again or “ringback” to
remind the user.
When multiple alarm conditions occur, active messages are displayed in the
display center one at a time, updating at 5-second intervals. Pressing
Silence during multiple alarms causes all active alarms to be muted and to
ringback in 15 minutes.
The temperature alarms are disabled when the Temp set point is 10°C.
