Explanation
The "Sensor stress" value reflects the current level of stress on the sensor
from rapidly changing temperatures and aggressive media (high conductivity
values measured in the high-purity water measurement or elevated reactivity
at high temperatures). When specified limit values are reached, the following
sensor stress alarm conditions are signaled on the JUMO digiLine master:
•
Pre-alarm for sensor stress above sensor stress level 3
•
Alarm for sensor stress above sensor stress level 7
This pre-alarm is generated at a sensor stress level greater than 3.
In addition to the "Sensor stress pre-alarm", this alarm is triggered at a sen-
sor stress level greater than 7 and generates a corresponding signal on the
JUMO AQUIS touch S/P. It can also be queried by a Modbus master (JUMO
mTRON T).
Number of previous CIP cycles identified as having exceeded the CIP tem-
perature
The CIP temperature is set in the configuration data.

perature

On reaching the maximum number of CIP or SIP cycles set for this pre-alarm
signal, this pre-alarm is triggered and generates a corresponding signal on
the JUMO AQUIS touch S/P. It can also be queried by a Modbus master (JU-
MO mTRON T).
The maximum number of CIP/SIP cycles for this pre-alarm is set in the con-
figuration data.

Explanation
The operating hours counter records the total operating time of the JUMO
digiLine electronics to the second. It cannot be configured or reset.
The sensor replacement counter records how often sensors on the JUMO
digiLine CR/Ci were replaced. It provides a history on the PC of archived sen-
sor information and calibration logbook entries for every sensor with which
the JUMO digiLine electronics were operated. The sensor replacement
counter is incremented by the JUMO DSM software.
