Alarms following deviations from the tolerance range or door opening
If the actual value, after having reached the setpoint, deviates by more than the set tolerance range value
and longer than 10 min. from the setpoint or the temperature doesn’t reach the tolerance range within 3
hours from turning on the chamber or closing the door, after the configured interval (e.g., “Temp range
alarm delay”) an alarm is triggered. It is visually indicated in Normal display. If the alarm buzzer is activated
(chap. 11.4) there is an audible alert. The zero-voltage relay alarm output (chap. 11.6) switches to transmit
the alarm. The alarm is shown in the list of active alarms (chap. 11.3).
