Frequently Asked Questions - PM2063 IFM

How to install the PM2063 sensor?

First mount the adapter (B) on the sensor with grease on the sealing chamfers. Then fasten the sensor and adapter onto the process connection using a nut or flange. Tighten to the stop without forcing.

How to electrically connect the sensor?

Use an M12 connector: pin 1 (BN) for L+, pin 2 (WH) for analog output, pin 3 (BU) for L-, pin 4 (BK) not connected. Observe TBTS/TBTP standards.

How to adjust the measuring range?

Set ASP (value at 4 mA) and AEP (value at 20 mA). The minimum difference between ASP and AEP is 25% of the span. Use the EPS-RS232 interface or PC software.

What happens if the pressure exceeds the measuring range?

The output signal exceeds 20 mA until saturation. Below the range, the signal can go down to 3.2 mA. Avoid pressure peaks.

How to clean the filter cover?

Unscrew the cover (B) with plastic pliers. Clean it carefully without compressing residues towards the vent (A). Screw the cover back on.

How to calibrate the zero point?

Use parameter COF to shift the working value by -5 to +5 % of the span. To reset to zero, use CAr.

Is the sensor compatible with the EPS-RS232 interface?

Yes, sensors with EPS-RS232 interface (option) can be connected to a PC via the E30066 interface. The E30069 software allows programming.

What is the required supply voltage?

The supply must be 14 to 30 V DC. With the EPS-RS232 interface, the minimum voltage is 15.5 V DC.

How to check proper operation after installation?

After mounting, wiring and adjustment, apply pressure and check the analog output (4-20 mA) and the display if present.

What to do in case of malfunction?

Check the supply, wiring and parameters. Consult the manual for possible error codes. Contact ifm support if necessary.

Safety instructions

Read the product description before installing the unit. Ensure that the product is suitable for your application without any restrictions.Non-adherence to the operating instructions or technical data can lead to personal injury and/or damage to property.In all applications check compliance of the product materials (see Technical data) with the media to be measured.

Function and features

The pressure sensor detects the system pressure and converts it into an analogue output signal (4 ... 20mA). The measuring range can be scaled to up to 25% of the value of the measuring range ( page 19). It is also indicated:

• System pressure above the measuring range: output signal > 20 mA.
• System pressure below the measuring range: output signal drops to max. 3.2mA (depending on the scaling).

Avoid static and dynamic overpressure exceeding the given overload pressure.

Even if the bursting pressure is exceeded only for a short time the unit can be destroyed (danger of injuries)!

The unit is ready for operation when delivered.

Factory preset: not scaled (ASP = 0 bar; AEP = 100% of the final value of the measuring range).

2 Use with factory setting

Installation

Before mounting and removing the sensor, make sure that no pressure is applied to the system.

The unit is adaptable for various process fittings. ifm adapters to be ordered separately as accessories.

Mount adapter (B) to the sensor first, then sensor + adapter to the process connection by means of a nut, a clamping flange or similar (A).

If it is not possible to slide the fixing element (A) down over the top of the sensor: slide it up over the bottom of the sensor before the adapter is mounted.

Note: Sensor and adapter are only to be mounted once.

Mounting of the adapter Step 1

Grease thread and sealing chamfer of the sensor and of the adapter with the greasing paste supplied.

The greasing paste is food-grade (USDA-H1 84-201).

Make sure that the O-ring (C) is correctly positioned.

Step 2

Screw the sensor into the adapter. Avoid mechanical influence on the sealing chamfers.

Step 3

Clamp sensor and adapter into a clamping device (D). The sealing chamfers (E) must not be damaged. Tighten the sensor with a spanner until you can feel the end stop.

Note: If you continue to turn, this can have adverse effect on the sealing.

Electrical connection

The unit must be connected by a suitably qualified electrician.

The national and international regulations for the installation of electrical equipment must be observed.

Voltage supply to EN50178, SELV, PELV.

Disconnect power before connecting the unit as follows:

Installation and set-up / operation / maintenance

After mounting, wiring and setting check whether the unit operates correctly.

Cleaning of the filter cover

If viscous and residues producing media clog the filter cover of the sensor (and thus reduce the measuring accuracy slightly), you can clean it.

Unscrew the filter cover (B) (use a pair of pliers with plastic-covered jaws for this). Clean the cover thoroughly.

The vent (A) should only be cleaned by skilled personnel and with utmost care.

Possible medium residues must not be compressed and pressed into the vent. This could clog the filter system and reduce the measuring accuracy of the sensor.

Screw the filter cover again tightly.

The sensor is sufficiently protected against harsh ambient conditions (protection IP 67). The protection rating can be increased by a special accessory (order no. E30043).

Connect the sensor to a PC via the EPS-RS232 interface (order no. E30066).

• The sensor is supplied with operating voltage by the interface,
• and transmits its data (measured values, analogue signal and parameter settings) continuously via the interface.

It provides the following options:

- Remote display

Indication of the current system pressure by PC or display.

- Remote evaluation

Output of the current analogue value.

- Programming / remote programming of the sensor

Scaling the measuring range, damping for the analogue output, calibration of the sensor.

Parameters can be set before the sensor is mounted and set up or during operation.

If you change the parameters during operation, the functioning of the plant will be affected. Ensure that plant malfunction is prevented.

Wiring of sensor and EPS interface

For use of the sensor with EPS interface prior to installation of the sensor: Use a suitable power supply (24V power supply; ifm order no. E30080).

For mobile use of the interface after installation of the sensor:

Disconnect power before connecting the unit.

Do not disconnect these connections while live.
