12.1.2 Operations When an Error Occurs
When an error occurs, the averaging converter operates as follows.
When a channel-specific error occurs:
1) The power to the heater of the corresponding detector is removed.
2) On the multi-channel display, a red error code is indicated under the relevant channel
and an error icon flashes in the switch indication area (Figure 12.1).
3) On the single-channel display, a large error code is indicated in the oxygen concentra-
tion data area and an error icon flashes in the switch indication area if the display
shows the relevant channel (Figure 12.2). If not, only a flashing error icon is indi-
cated.
4) The relevant channel is dropped out of the averaging group. The averaging outputs
continue with exception of the channel.
5) The corresponding individual analog output is put into the status specified in the
Output Hold Setup display. No other individual analog outputs are affected.
6) The red lamp turns on in the status display lamp on the relevant channel.
7) The individual error contact and common error contact are activated.
