Section 4 - Alarms
4.1 Alarms
The Model 3950 Series incubator is equipped with a sys-
tem 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 cor-
rectly, 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 with-
out 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-sec-
ond 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. The CO
2
alarms are disabled when the CO
2
set
point is 0.0%.

4.2 Sensor Fault Alarms
The microprocessor in 3950 Series incubators continually
scans all available sensors to ensure that they are operating
properly. Should an error be detected, the incubator will sound
an alarm and display the appropriate message. If such an alarm
occurs, contact your local distributor or the Thermo Forma
Service department at 740-373-4763 or 1-888-213-1790
(U.S.A. and Canada) or fax 740-373-4189.
