Endress+Hauser 11

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

Product description Ceraphant PTC31B, PTP31B, PTP33B IO-Link

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.

5.1 Mounting dimensions

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

5.2 Installation 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, 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.

A0022252

5.3 Influence of the installation position

Any orientation is possible. However, the orientation may cause a zero point shift i.e. the measured value does not show zero when the vessel is empty or partially full.

6.1.2 Supply voltage

Supply voltage IO-Link: 10 to 30 V DC at a DC power unit

IO-Link communication is guaranteed only if the supply voltage is at least 18 V.

6.1.3 Current consumption and alarm signal

Intrinsic power consumption Alarm current (for devices with analog output)

≤ 60 mA ≥21 mA (factory setting)

Maximum current consumption: ≤ 300 mA

1) Setting min. alarm current ≤3.6mA can be ordered via the product order structure. Min. alarm current ≤3.6mA can be configured at the device or via IO-Link.

6.2 Switching capacity

• Switch state ON

: Ia ≤ 200 mA

• Switch cycles: >10,000,000

• Voltage drop PNP: ≤2 V

• Overload protection: Automatic load testing of switching current;

– Max. capacitive load: 1 μF at max. supply voltage (without resistive load) – Max. cycle duration: 0.5 s; min. ton: 40 μs – Periodic disconnection from protective circuit in the event of overcurrent (f = 2 Hz) and

"F804" displayed

; switch state OFF: Ia ≤100 μA

6.3 Connection data

6.3.1 Load (for devices with analog output)

In order to guarantee sufficient terminal voltage, a maximum load resistance RL (including line resistance) must not be exceeded depending on the supply voltage UB of the supply unit.

The maximum load resistance depends on the terminal voltage and is calculated according to the following formula:

1) 100 mA can be guaranteed over the entire temperature range for the switch outputs "2 x PNP" and "1 x PNP + 4 to 20 mA output". For lower ambient temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. 200 mA can be guaranteed over the entire temperature range for the "1 x PNP" current output.

2) Larger currents are supported, thus deviating from the IO-Link standard.

7.1.1 IO-Link

IO-Link information

IO-Link is a point-to-point connection for communication between the measuring device and an IO-Link master. The measuring device features an IO-Link communication interface type 2 with a second IO function on pin 4. This requires an IO-Link-compatible assembly (IO-Link master) for operation. The IO-Link communication interface enables direct access to the process and diagnostic data. It also provides the option of configuring the measuring device on the fly.

Physical layer, the measuring device supports the following features:

• IO-Link specification: version 1.1

• IO-Link Smart Sensor Profile 2nd Edition (supports minimum scope of IdentClass)

• SIO mode: yes

• Speed: COM2; 38.4 kBaud

• Minimum cycle time: 2.5 msec.

7.1.2 Operating concept

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

User role Meaning

Operator (display level)

Maintenance (user level)

Operators are responsible for the devices during normal "operation". This is usually limited to 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.

Service engineers usually work with the devices in the phases following device commissioning. 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.

operating errors.

7.2 Operation with local display

7.2.1 Overview

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" →  73). 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.

7.2.2 Information on the operational states

Operational states Function of status-LED and onsite display

Operation • Status LED is lit green

• LEDs of switch output 1 and switch output 2 signal the status of each switch output

• No activity of LED for switch output 2 if current output is active

• White background lighting

Problem • Status LED lit steady red

• Red display background

• LED of switch output 1 and switch output 2 off (switch output is deactivated)

Warning • Status LED flashing red

• White display background

• LEDs of switch output 1 and switch output 2 signal the status of each switch output

For Device Search • The green LED is lit (= operational) on the device and starts to flash with increased

luminosity. Flash frequency

• LEDs of switch output 1 and switch output 2 signal the status of each switch output

• Display background depending on the device status

IO-Link communication

• Status LED flashes green as per IO-Link specification (regardless of measuring operation, error or warning). Flash frequency

• Display background depending on the device status

• The state of switch output 1 is also indicated via the LED of switch output 1 at the same time as the process data are displayed

7.3 General 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.

7.4 Navigation and selection from list

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

7.5 Locking 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.

7.5.1 Disabling 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.

7.5.2 Locking and unlocking parameter settings

The device settings can be protected from unauthorized access.

COD parameter: define the locking code

0000 Device is permanently unlocked (factory setting)

0001-9999 Device is locked

LCK parameter: unlock parameter locking (enter the COD)

If parameters are locked, the word "LCK" appears on the local display as soon as an attempt is made to change a parameter.

Examples:

Locking the device with a customer-specific code

1. EF → ADM → COD

2. Enter a COD not equal to 0000 (value range: 0001 to 9999)

3. Wait 60 seconds or restart the device

4. Parameters are locked (protected against changes)

Changing a parameter when the device is locked (taking the example of STL)

1. STL, LCK is displayed
