16.2.2 RD4 controller

In the event of equipment failures, when the temperature and / or pressure deviate from the set tolerance
range limits, optical and possibly acoustic alarm messages are given out via the controller.
The alarm messages on leaving the tolerance range are emitted after a configurable delay (chap. 15.2.1,
15.2.2), the others immediately when the fault occurs. The tolerance range alarm is suppressed after
turning on the chamber 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 "coll-
ective alarm" icon is lit.
