Error messages
The error detection system is an integral element of the device-internal control system. It monitors the
control loops and their sensors. If an error is detected in the system, the alarm relay switches and issues
the following signals and messages:
• An audible alarm sounds,
• The main menu is overlaid by a flashing warning triangle and the pertinent icon; the value
indicators are no longer updated,
• the detected error is listed in the error table,
• the event is entered into the event display,
• When an error condition persists although it has been acknowledged, that error can be redisplayed
by pressing a red key (T, CO
2
, O
2
, RH or system, Menu key).
Response to an error message event
If the alarm relay was switched due to a user action, the switching state can be reset by accepting the
error message (e.g. for the manual cancellation of the steri-run decontamination routine).
If the alarm relay was switched due to a technical defect, the switching state remains active until the
defect has been corrected (e.g. low water level in workspace).
1. To accept the failure message:
• If the warning triangle is displayed, press any position on the touchscreen.
• The
Error
dialog box appears and the detected error is displayed,
• the audible alarm is switched off.
2. To exit the error display:
• Press the
End
key [3].
• The error message disappears.
