14.1 Alarm messages
WARNING: If customer should use a chamber running in non-supervised continuous opera-
tion, we strongly recommend in case of inclusion of irrecoverable specimen or samples to
split such specimen or samples and store them in at least two chambers, if this is feasible.
In the event of equipment failures, when the temperature deviates from the set tolerance range limits,
optical and possibly acoustic alarm messages are given out via the controller. A zero-voltage relay alarm
output (9) (chap. 14.4.7) permits transmission of the alarm e.g., to a central monitoring system.
The alarm messages door open and leaving the tolerance range are emitted after a configurable delay
(chap. 13), the others immediately when the fault occurs. The tolerance range alarm is suppressed after
opening the chamber door or turning on the freezer until the setpoint is reached and then for the selected
delay time.
In Normal display a text message indicates the alarm cause. The “collective alarm” icon flashes. If
the audible arm is activated, the buzzer sounds.
If more than one alarm signal is sent simultaneously, they are displayed in a cycle.
Press the OK button to confirm the alarm and mute the buzzer. If the alarm cause is still valid, the “collec-
tive alarm” icon is lit.
