3.2.1Calculating the pressure

Devices with ceramic process isolating diaphragm (Ceraphire®)

The ceramic sensor is an oil-free sensor, i.e. the process pressure acts directly on the robust ceramic process isolating diaphragm and causes it to deflect. A pressure-dependent

Endress+Hauser

11

Product description	Ceraphant PTC31B, PTP31B, PTP33B

change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm. The measuring range is determined by the thickness of the ceramic process isolating diaphragm.

Devices with metallic process isolating diaphragm

The process pressure deflects the metal process isolating diaphragm of the sensor and a fill fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

5Installation

5.1Mounting dimensions

For dimensions, see the "Mechanical construction" section in the Technical Information.

5.2Installation conditions

•Moisture must not penetrate the housing when mounting the device, establishing the electrical connection and during operation.

•Do not clean or touch process isolating diaphragms with hard and/or pointed objects.

•Do not remove process isolating diaphragm protection until shortly before installation.

•Always tighten the cable entry firmly.

•Point the cable and connector downwards where possible to prevent moisture from entering (e.g. rain or condensation water).

•Protect housing against impact.

•For devices with gauge pressure sensor and M12 or valve plug, the following applies:

NOTICE

If a heated device is cooled in the course of a cleaning process (by cold water, for example), a vacuum develops for a short time causing moisture to penetrate the sensor via the pressure compensation element (1).

Device could be destroyed!

In the event of this happening, mount the device in such a way that the pressure compensation element (1) is pointing downwards at an angle or to the side, if possible.

2Shutoff device

Pressure measurement in vapors

For pressure measurement in vapors, use a siphon. The siphon reduces the temperature to almost ambient temperature. Preferably mount the device with the shutoff device and siphon below the tapping point.

Advantage:

•defined water column causes only minor/negligible measuring errors and

•only minor/negligible heat effects on the device.

Mounting above the tapping point is also permitted.

Note the max. permitted ambient temperature of the transmitter!

Take the influence of the hydrostatic water column into consideration.

7Operation options

7.1Operation with an operating menu

7.1.1Operating concept

Operation with an operating menu is based on an operation concept with "user roles" .

User role	Meaning
Operator	Operators are responsible for the devices during normal "operation". This is usually limited to
(display level)	reading process values either directly at the device or in a control room. Should an error occur,
	these users simply forward the information on the errors but do not intervene themselves.
Maintenance	Service engineers usually work with the devices in the phases following device commissioning.
(user level)	They are primarily involved in maintenance and troubleshooting activities for which simple
	settings have to be made on the device. Technicians work with the devices over the entire life
	cycle of the product. Thus, commissioning and advanced settings and configurations are some
	of the tasks they have to carry out.

7.2Structure of the operating menu

The menu structure has been implemented according to VDMA 24574-1 and complemented by Endress+Hauser-specific menu items.

User role	Submenu	Meaning/use
Operator (display	Display/operat.	Display of measured values, fault and information messages
level)
Maintenance (user	Parameters on	Contains all the parameters that are needed to commission
level)	the topmost	measuring operations. A wide range of parameters, which can be
	menu level.	used to configure a typical application, is available at the start. After
		making settings for all these parameters, the measuring operation
		should be completely configured in the majority of cases.
	EF	The submenu "EF" (Extended Functions) contains additional
		parameters which allow more accurate configuration of the
		measurement, conversion of the measured value and scaling of the
		output signal.
	DIAG	Contains all the parameters that are needed to detect and analyze
		operating errors.

For an overview of the entire operating menu, see the → 47

7.3Operation with local display

7.3.1Overview

A 1-line liquid crystal display (LCD) is used for display and operation. The local display shows measured values, fault messages and information messages and therefore supports the user through each operating step.

The display is fixed to the housing and can be electronically rotated 180° (see parameter description for "DRO" → 62). This ensures optimum readability of the local display and allows the device to be mounted upside down also.

During measuring operation, the display shows measured values, fault messages and notice messages. In addition, it is possible to switch to menu mode via the operating keys.

7.4General value adjustment and rejection of illegal entries

Parameter (not numerical value) is flashing: parameter can be adjusted or selected.

When adjusting a numerical value: the numerical value does not flash. The first digit of the numerical value starts to flash only when the key is pressed by way of confirmation. Enter the desired value with the or key and press the key to confirm. Following confirmation, the data are recorded directly and are active.

–Entry is OK: value is accepted and shown for one second on the display against a white background.

–Entry is not OK: the message "FAIL" appears for one second on the display against a red background. The value entered is rejected. In the event of an incorrect setting which affects the TD, an diagnostic message is displayed.

7.5Navigation and selection from list

The capacitive operating keys are used for navigation in the operating menu and to select an option from a picklist.

Operating key(s)		Meaning
		• Navigate downwards in the picklist
		• Edit the numerical values or characters within a function

7.6Locking and unlocking operation

The device features

•Automatic key locking

•Parameter settings lock.

Key locking is indicated on the local display by "E > 2".

Locking of the parameter settings is indicated as soon as an attempt is made to change a parameter.

7.6.1Disabling the key lock

The keys are locked automatically if the device remains at the topmost menu level (display of pressure measurement value) for 60 seconds.

Call up the key lock function (KYL)

1.Press the key for at least 2 seconds and then release it

2.By confirming with "ON" is displayed

3.Use and to toggle between "ON" and "OFF"

4.Key locking is disabled as soon as is pressed to confirm "OFF"

The display changes to the main value level (topmost menu level) if the key is pressed briefly. The display changes to the key locking if the key is pressed for at least 2 seconds.

If in the case of "KYL", "ON" or "OFF", more than 10 seconds elapse without a key being pressed, you return to the topmost menu level with active key locking.

The function can be accessed anytime outside the main measured value display and within the operating menu, i.e. if the key is pressed for at least 2 seconds key locking can be performed anytime at any menu item. Locking is effective immediately. If you quit the context menu, you will return to the same point from which key locking was selected.
