Frequently Asked Questions - PY2006 IFM

How do I install the PY2006 pressure sensor?

Before installation, ensure no pressure is applied and no medium is in the pipe. Use a suitable process connection (e.g., G1 Aseptoflex Vario) and tighten to 35 Nm. Do not exert axial leverage on the rotatable filter cover. Align the cover for proper drainage.

What are the electrical connection options?

The sensor supports 2-wire and 3-wire operation. In 2-wire mode, OUT2 provides the analogue signal (4...20 mA). In 3-wire mode, OUT1 is IO-Link and OUT2 is analogue. Connect according to the wiring diagram using brown (BN), white (WH), blue (BU), and black (BK) wires per DIN EN 60947-5-2. Power supply must be SELV/PELV.

How can I configure the sensor parameters?

Parameters can be set via IO-Link using a PC with IO-Link software (e.g., LINERECORDER DEVICE) and an ifm interface. Alternatively, use a memory plug (ifm storage module) to transfer settings. A teach button (E30425) allows zero-point calibration.

What is IO-Link and how does it benefit me?

IO-Link is a communication interface that provides direct access to process data, diagnostic information, and parameter settings. It enables remote monitoring, configuration, and fault detection. The device supports IO-Link with fully bidirectional communication.

Can I scale the measuring range?

Yes, the measuring range is scalable to up to 20% of the final value. Set [ASP2] for the start point (4 mA) and [AEP2] for the end point (20 mA). The minimum distance between ASP and AEP is 20% of the measuring span.

How do I set damping for the output?

For the analogue output, set parameter [dAA] (rise time 10...90%) between 0.000 and 4.000 seconds. For the switching signal (IO-Link process data), set [dAP] (t value 63%) in the same range. Damping filters out short pressure peaks.

What does the fault indication mean?

If a fault is detected, the analogue output goes to 21.5 mA (Namur indication). This indicates a malfunction. Read parameters via IO-Link or contact the manufacturer to identify the issue.

How do I clean and maintain the sensor?

Clean the ventilation diaphragm immediately with plenty of lime-deficient splash water if soiled. Avoid contact with liquids when the sensor is cooling. Replace the filter cover if damaged or as needed (versions: E30142, E30148, E30139). Follow the orientation guidelines for the GORE diaphragm.

What spare parts are available?

Spare parts include the filter cover with GORE diaphragm (E30142), closed filter cover (E30148), tube fitting version (E30139), and accessory set (E30467). Also available: sealing rings (EPDM, FKM, PEEK), memory plug, and teach button (E30425).

Is the sensor suitable for hygienic applications?

Yes, when used with certified adapters (3A or EHEDG), it meets hygienic standards. Ensure self-draining installation and use leakage ports. Not suitable for 3A standard E1.2/63-03 criteria. Observe temperature and material resistance limits from the data sheet.

5.4 Ventilation diaphragm with protective cover

5.4.1 Function ventilation diaphragm

The ventilation diaphragm enables the relative pressure measurement since barometric and temperature-dependent pressure fluctuations between the measuring cell and the environment are compensated for.

The ventilation diaphragm is protected against damage by a screwed cap with circumferential ports.

For a correct functioning of the diaphragm please take the following into account:

▶ Remove soiling and cleaning agents immediately using plenty of lime-deficient splash water.

If the sensor is in a cooling stage:

▶ Avoid contact of the diaphragm with liquids to avoids negative pressure in the measuring system resulting in a slightly falsified measured value and additional strain on the diaphragm.

5.4.2 Orientation of the filter cover

The filter cover is freely rotatable around the sensor's axis and thus adaptable to the environmental conditions.

When the sensor is mounted in a vertical position, the condensate escapes through the ports in the protective cap due to gravity.

When the sensor is mounted in a horizontal position or similar, the filter protection cap must be rotated towards one of the two lateral faces to bring the GORE diaphragm into a vertical position. This guarantees the optimum drainage for liquids.

To ensure an optimum function of the pressure compensation element, align the filter cover as shown in fig. 1.
