ES Series Lab Freezer
14
Warning Alarms
Note:
When a unit is first plugged-in and powered on, the High Alarm will sound during the initial pull-down to temperature
set-point. Press the alarm mute button to silence the alarm during pull down.
This Freezer has been designed to provide both an audible and visual alarm should any of the following situations occur:
-
•
Door is left open for a set period.
•
Internal air temperature goes outside the set parameters, either too high or too low.
•
Internal ‘load’ temperature goes outside the set parameters, either too high or too low.
•
Should one of these alarms occur this can be muted by pressing
on the controller.
The ‘load’ temperature is a simulated temperature which is intended to provide an indication of the temperature of the
freezer
’s contents (e.g. a 5ml sample). The temperature of a freezer’s contents will change more slowly (up or down) than
the air temperature within that freezer should there be a fault, or the door is left open.
