of the slope to automatic or individual.
04.
If you select “Individual”: The nominal slope and the min/max limits can be entered.
05.
In the
Message
menu item, select whether and how an exceeded limit is to be displayed:
Off
No message, but the parameter is still shown on the sensor diagram.
Failure
A failure message is shown in off-limit conditions; the corresponding NAMUR icon
is displayed.
Maintenance
A maintenance required message is shown in off-limit conditions; the corresponding NAMUR icon
is displayed.
06.
Set the sensor monitoring details for other sensor data, e.g. zero point, Sensocheck, response time,
sensor wear, or sensor operating time.
07.
Using the
left softkey: Back
, confirm the sensor monitoring settings and adjust further parameters.
or
Using the
right softkey: Back to Meas.
, confirm the sensor monitoring settings and end the func-
tion check (HOLD).
CIP/SIP Counters
Note:
A CIP counter is available for the SE740 oxygen sensor.
An SIP counter is available for amperometric Memosens oxygen sensors.
CIP/SIP cycles are used to clean or sterilize process-wetted parts in the process. Depending on the
application, either one chemical (alkaline solution, water) or several chemicals (alkaline solution,
water, acidic solution, water) are used.
• CIP temperature > 55 °C/131 °F
• SIP temperature > 115 °C/239 °F
The cleaning (cleaning in place) and sterilization (sterilization in place) cycles are counted to measure
the load on the sensor, e.g., in biotechnology applications.
Note:
If measurements are generally taken at high temperatures (> 55 °C/131 °F), the counters should
be switched off.
When a CIP/SIP counter is switched on, a maximum number of cycles can be entered. As soon as the
counter has reached the specified value, a maintenance required message is triggered and the NAMUR
icon
is displayed.
Note:
A CIP or SIP cycle is only entered into the logbook 2 hours after the start to ensure that the cycle
is complete.
Note:
With Memosens sensors, an entry is also made in the sensor.
