CIP/SIP Counters, p. 94
D110 CIP Counter Configured number of CIP cycles exceeded: As required, recalibrate/read-
just sensor or replace.
D111 SIP Counter Configured number of SIP cycles exceeded: As required, recalibrate/read-
just sensor or replace.
D112 Autoclaving Counter Configured number of autoclaving cycles exceeded: As required, recali-
brate/readjust sensor or replace.
D113 Sensor Operating
Time
Sensor operating time exceeded.
Replace the sensor.
D114 Membrane Body Re-
placement
Replacement of the membrane body required.
Replacement of the membrane body must be confirmed in the Mainte-
nance menu. ➜
Maintenance Functions for Oxygen Sensors, p. 134
D120 Wrong Sensor If sensor check is active: An impermissible sensor is connected to the
device.
- Replace sensor.
- Change the process variable.
D121 Sensor Error
(Factory Settings)
The digital sensor indicates an error. The sensor no longer works properly.
Replace the sensor.
D122 Sensor Memory (Cal
Data)
The digital sensor indicates an error. The calibration data are defective:
Recalibrate/readjust sensor.
D123 New Sensor,
Adjustment Required
A new digital sensor was connected. It must now be adjusted.
D124 Sensor Date The date of the sensor is implausible.
e.g., calibration data “from the future”: Check and, as necessary, adjust the
configuration.
D200 Temp O2 Conc/Sat The temperature is outside the valid range for oxygen concentration/
saturation.
