JUMO dTRANS p35 Manual

The installation direction is arbitrary, but it is necessary to avoid wear at the process connection.

3.2 Installation steps

Manually screw the sensor into the corresponding threaded hole to ensure that the sealing ring (such as O-ring) is in the correct position.

Tighten with a suitable wrench, and refer to the "Process Connections" table on page 17 of the document for torque values (torque varies for different connection forms).

For hygienic applications (EHEDG), the following principles should be followed:

Install with as few cavities as possible.

The connecting socket should be self draining.

When installed on the tank, it must be level to ensure that the cleaning spray directly covers it.

The leakage hole should be clearly visible, with the vertical pipeline facing downwards.

3.3 Special requirements for EHEDG compliance

The document clearly states that the following process connections are applicable to EHEDG: 613, 616 (clamp DN25~50, sealed with Tri Clamp) and 997 (JUMO PEKA, FKM O-ring). During installation, it is necessary to ensure that L<D (cavity depth less than diameter) and regularly check for leakage holes.

Electrical connections and IO Link configuration

4.1 Definition of M12 connector pins

The sensor uses M12 × 1A coded circular plug, and the color coding conforms to the standard cable:

Pin color signal (SIO mode) signal (IO Link mode)

1 Brown (BN) L+(9.6~32V DC) L+(18~32V DC)

2 White (WH) I/Q (OUT2) I/Q (OUT2)

3 Blue (BU) L - L-

4 Black (BK) C/Q (OUT1) C/Q (IO Link)

Potential equalization: Functional grounding is achieved through process connections.

UL application: The cables used must have UL certification (such as AVLV2/8 or CYJV/7) and be suitable for environments above 90 ° C.

4.2 Connection Example

On page 23 of the document, four types of connection diagrams are provided:

IO Link operation+1 switch output (OUT2 as PNP or NPN)

Switch operation+2 switch outputs (PNP or NPN)

In IO Link mode, OUT1 is used for communication, while OUT2 can still be used as an independent switch output. The sensor automatically detects the connection type (IO Link or SIO).

4.3 IO Link Startup Process

Start the IO Link master station hardware and software.

Download IODD file: Visit www.jumo.de, search for "402058", download the ZIP compressed file under "Software", unzip it, and locate the IODD based on the device ID (see nameplate).

Backup address: http://ioddfinder.io-link.com

Import IODD into the configuration tool and update the device directory.

Create a project, establish connections, and perform parameter reading and writing, process data monitoring, and diagnosis.

Detailed explanation of device functions

The configuration parameters of dTRANS p35 are accessed through the index/sub index of IO Link, mainly divided into process data, configuration data, and service data.

5.1 Switching point function

Each switch output can be independently configured into four modes: hysteresis normally open, hysteresis normally closed, window normally open, window normally closed, or closed.

Hysteresis function

The switch point (SP) and release point (rSP) must meet the requirement of SP ≥ rSP.

Output action when the measured value exceeds SP, reset when it is below rSP. Hysteresis width=SP - rSP.

Suitable for single limit monitoring of liquid level, pressure switch, etc.

window function

Defined by window low (FL) and window high (FH), FH ≥ FL.

When the measured value is within (FL, FH), output an action and reset outside the window. The hysteresis of the window is fixed at ± 0.25% range (symmetrical).

Suitable for pressure range monitoring, such as detecting whether the pressure is within the allowable range of the process.

Switch delay

Connection delay (VSP): After the measured value crosses the SP, the delay set time output is closed.

Turn off delay (VrSP): The delay setting time output will only disconnect when the measured value is below rSP.

Range 0-100 seconds, capable of filtering out pressure spikes or disturbances.

5.2 Fine tuning (two-point correction)

When there is a non-linear deviation between the sensor measurement value and the reference value, the fine-tuning function can be used to correct the characteristic curve (offset+gain correction).

parameter

Active: Yes/No

Actual start value - current measurement value of the sensor

Target start value - reference measurement value

Actual end value

Target end value

Operation steps (taking pressure vessels as an example):

Set the container pressure to a low point (such as 20 bar) and record the reference instrument value.

Read the sensor value (such as 15 bar) and input it as the "actual starting value"; Enter a reference value of 20 bar as the 'target starting value'.

Set the container pressure to a high point (such as 80 bar), with a reference value of 80 bar, and the sensor displays 70 bar.

Enter the actual endpoint at 70 bar and the target endpoint at 80 bar.

Activate fine-tuning.

After fine-tuning, the characteristic curve changes, but the data is not stored in the parameter manager (it needs to be reloaded or written through IO Link every time it is powered on). The actual starting/ending values can be quickly set through the teaching function.
