10.2.3The structure of the cleaning and calibration programs

The cleaning and calibration program is configured via the local display. Customer-specificprograms can be created by Endress+Hauser specialist staff. Programs are divided into
steps, sequences and programs.
Steps• Certain actions concerning sensor cleaning and/or calibration are divided into individual
steps.
A step defines:• The state of the outputs (valves, DO).
• The state of the inputs (DI).
• Steps 1-16 are preconfigured, while steps with IDs 17-26 can be tailored to customer
requirements.
Sequences
The sequences comprise the order and duration of the steps. User-specific sequences canbe defined. Predefined sequences can be integrated into the user-defined sequences.
Predefined sequences are preconfigured on delivery.
Programs
A program is a sequence that has been assigned to a specific channel.
Schedules
You can assign a schedule to the programs; the program is then executed automatically ata defined frequency based on this schedule.

1

Service Position

Sets the valves of the implicit channel to move thesensor to the service position.
End condition: the step ends when it is possible todetect that the service position has been reached.
A timeout should trigger an error.
The timeout can be configured under Application/
Operating type and units/Measuring Point 1 or

Measure Position

Sets the valves of the implicit channel to move thesensor to the measure position.
End condition: the step ends when it is possible todetect that the measure position has been reached.
A timeout should trigger an error.
The timeout can be configured under Application/
Operating type and units/Measuring Point 1 or

3

H2O + Service Pos.

Switches the water valve on and sets the valves of theimplicit channel in such a way that the sensor is
moved to the service position.
Switches the water valve off once the sensor has
reached the service position.
The preconfigured step switches the outputs off again.
The preconfigured step cannot be edited.
A timeout should trigger an error.
The timeout can be configured under Application/
Operating type and units/Measuring Point 1 or
Measuring Point 2

4

H2O + Measure Pos.

Switches the water valve on and sets the valves of theimplicit channel in such a way that the sensors are
moved to the measure position ("sealing water").
Switches the water valve off once the sensor has
reached the measure position.
A timeout should trigger an error.
The timeout can be configured under Application/
Operating type and units/Measuring Point 1 or

5

Hold On

If the HOLD function is switched on, this causes themeasured values to "freeze" or a predefined measured
value to be displayed. This concerns the analog andfieldbus outputs.
This makes sense during a calibration.
The HOLD behavior can be configured.
