5.
After the Device reaches the set point (indicated when the set point readout is no longer flashing), allow the
temperature to stabilize for an additional 10 minutes.
NOTE: A temperature overshoot will be noted when
testing this way, which is normal.
6.
After 10 minutes, the reading on the temperature sensor should be /-1°C of the set-point temperature.
When measuring temperature, the accuracy and tolerance of the sensor must be taken into account. This will
depend on the type of sensor being used and can range from +/- 0.2°C to +/- 2.0°C. The measurement
tolerance of the sensor must be added to the +/- 1.0°C tolerance for the System to determine the pass/fail
criteria for this test. For example: If the Controller is set to 41°C, and the measurement is being made with a
temperature sensor that has a +/- 1.0°C measurement tolerance, the acceptable range of measured temperatures
will be 39 to 43°C. (i.e. 41 +/- 2°C).
7.
Repeat steps 4-6 for the next temperature setting, if required.
Error Codes: Alerts & Alarms
When an Alarm or Alert condition occurs, the associated error code will remain on the display until the
condition is resolved.
If multiple Alarm or Alert conditions occur sequentially, the code associated with the highest priority Alert
condition will be displayed first, followed by the next highest priority alarm or alert condition until all Alarm
or Alert conditions have been displayed to the user. Once all Alarm or Alert conditions have been displayed,
the display will return to the main operating screen where the error codes will still be present on the screen in
place of the temperature set point.
If a new Alarm or Alert condition occurs, all active Alarm or Alerts will be displayed to the user again sorted
by priority as described above.
To resolve an Alarm, follow the on-screen instructions. Devices will not be active when an Alarm is
occurring.
