Error Messages


How do I respond to error messages?


  • Heracell VIOS 160i

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 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  • The value indicators are no longer updated;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; and
  • 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, CO2, O2, RH or system, Menu key).


  • 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).
Accepting the Failure Message
  1. If the warning triangle is displayed, press any position on the touchscreen.
  2. The Error dialog box appears and the detected error is displayed. The audible alarm is switched off.
Exiting the Error Display

Press the End key [3], and the error message disappears.
