Section 4 Alarms
The Model 310 Series incubator alarm system is shown in the table below.
When an alarm is active, the message appears in the LED message center.
Pressing Silence disables the audible alarm for the ringback period.
However, the visual alarm continues until the incubator returns to a
normal condition. The alarms are momentary alarms only. When an alarm
condition occurs and then returns to normal, the incubator automatically
clears the alarm condition and the message center.
When multiple alarm conditions occur, active messages are displayed in
the message center one at a time, updating at 5 second intervals. Pressing
Silence during multiple alarms causes all active alarms to be silenced and to
ring back in 15 minutes.
The temperature alarms are disabled when the Temp set point is 10°C.
The CO
2 alarms are disabled when the CO2 set point is 0.0%.
