Operating the Integra 750Plus
2. If the solenoid valve has stopped for more than five minutes, estimate the temperature
of the samples by:
- Estimating the amount of time that the program has been running for.
-
Reading the temperature off from the DeltaT window.
- Pulling off the exhaust fitting and inserting a thermometer (suitable for use to -
200ºC) into one of the exhaust holes.
3. If the samples are above their freezing point, open the door and allow the samples to
warm up.
4. If the samples are below their freezing point, use the COOL override button on the
rear panel of the freezer to go to the final temperature.
5. Following a system lockup, you need to reset the freezer's controller. The reset
button is operated by inserting the tip of a ball-point pen or similar tool through the
hole in the rear panel, located between the manual over-ride button and the AUX
socket. Alternatively, switch off and on again. If the freezer needs to be lifted and/or
rotated to gain access, refer to the Lifting Instructions in
Chapter 2: Installing the
Integra 750Plus System .
6. Operate the freezer through a couple of trial runs to ensure that there is no
permanent fault.
3.3 Alarms
If a fault condition is detected, the freezer will generate an alarm. The alarm is indicated
by a continuous tone from the internal buzzer. An alarm is generated under the following
fault conditions:
·
The current temperature deviates from the expected freezing profile by more than 10 °
C. In this case, the light near the RUN button will remain illuminated indicating that the
run is still in progress.
·
The chamber temperature probe is faulty. In this case the freezing profile will also be
terminated and the light near the RUN button will switch off indicating that the run has
terminated.
