5.2 Temp Controller Failure TEMP CNTRL ERROR
In addition to other safety features designed into Steri-Cult
incubators, a thermostat is provided to monitor the cabinet tem-
perature. In the event of a temperature control failure, the ther-
mostat will turn off all heaters at a cabinet temperature of
160°C (±5%). This is intended to be a safety feature to protect
the incubator, and is not intended to protect the cell cultures or
the equipment inside the chamber should a temperature control
failure occur. Should such a failure occur, contact the Technical
Services Department or your local distributor.
5.3 RH System Fault
This alarm occurs if the humidifier has been detected as
being on for an abnormal length of time. Possible causes are:
1. RH calibrated too low.
2. Humidifier tubing pinched or disconnected.
3. Access port is plugged.
4. Ultrasonic humidifier has heavy build-up. See Section
6.3, Cleaning the Humidity System.
5. If none of the above, contact the Services department.
5.4 Sensor Fault Alarms
The microprocessor in Steri-Cult 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. Contact the
Technical Services Department (1-888-213-1790) or your local
distributor.
5.5 Gas Guard Alarms
If the Gas Guard option is installed, the choice of tank is
available in Configuration mode. If the tank in use goes low,
the unit automatically switches to the other tank. However, an
audible alarm and warning light activate indicating the low tank
condition. Pressing Silence clears the alarm condition and does
not ringback. The warning light on the display remains activat-
ed until the tank is replaced and both tanks are normal.
If the tank not in use goes low, the warning light is activat-
ed. If both banks go low, the audible alarm and warning light
are activated.
5.6 Water Level Alarms
When the water level in the bottle falls to approximately
3 inches (7.6cm), a visual alarm with display message “WATER
LOW” occurs. Pressing Silence clears the alarm condition and
does not ringback. The blue backlight on the water bottle flash-
es until the bottle is filled.
If the water bottle is not refilled and the bottle becomes
empty, an audible alarm with display message “WATER
EMPTY” occurs. Pressing Silence mutes the audible alarm but
it rings back in 15 minutes. The blue backlight on the water
bottle flashes until the bottle is filled.
If the water level inside the humidification system is not as
required, yet the water level in the bottle is not low, then an
audible alarm with display message “NO WATER FLOW”
occurs. Pressing Silence mutes the audible alarm but it rings
back in 15 minutes until the condition is resolved.
5.7 Door Open Alarm
When the door is opened on the Steri-Cult incubator, heat
and CO
2
injection are disabled. The door must be securely
latched for heat and CO
2
injection to resume after a door open-
ing.
If the door is latched, yet the display still shows Door Ajar,
the door switch could be faulty. Call Technical Services.
