Troubleshooting
6.1
Heating and cooling process take too long
The device is equipped with strong fans that remove the heat from the heat sink. The air
inlet to these fans is located on the underside of the device. The air inlet may be ob-
structed by soiling or objects such as a piece of paper that is drawn in by the fan’s draft.
If this is the case, the device will not achieve the desired heating and cooling rates.
}
Check whether the air inlet is obstructed by soiling or objects.
}
Frequently use a vacuum cleaner or a brush to remove soiling from the air inlet.
6.2
Automatic restart after power failure
The device has an automatic restart function. In case of a power failure during a PCR
run, the device will resume running as soon as the power supply is reestablished.
In the event of a prolonged power failure (≥30 min) the Freeze program will start auto-
matically: The device will then cool down the sample block to 4 °C. You can then decide
whether to repeat the run or to discard the samples.
After an automatic restart, you have to log in again as a user.
6.3
Automatic restart without an apparent cause
Strong voltage fluctuations may trigger a restart of the device. The reaction of the device
in this case will be the same way as in case of a power failure.
The device will than indicate on the touch screen that a power failure has occurred dur-
ing the run. The text on the screen will mention the time and the step with which the
program was restarted.
To prevent sudden voltage fluctuations, do not connect the device to electrical circuits
also connected to other devices requiring high levels of energy such as freezers or cen-
trifuges.
After an automatic restart, you have to log in again as a user.
