Safety instructions

Please read the product description prior to installing the unit.

Please check that the product is suitable for your application

without any restrictions.

If the operating instructions or the technical data are not

adhered to, personal injury and/or damage to property may

occur.

Please check in all applications that the product materials (see

Technical data) are compatible with the media to be mea-

sured.

The pressure sensor detects the system pressure and converts it into

an analog output signal (4 ... 20 mA). The measuring range can be

scaled to up to 25% of the value of the span (→page 19, 21).

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. 3.2 mA (depending on the scaling).

Applications :

Avoid static and dynamic overpressure exceeding the given over-

load 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.

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 acces-

sories.

Mount adapter (C) to the sensor

(A) first, then sensor + adapter to

the process connection by means

of a nut, a clamping flange or

similar (B).

If it is not possible to slide the fix-

ing element (B) 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 cham-

fer 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 (D) is

correctly positioned.

Grease

Use with factory setting

Step 2

Screw the sensor into the

adapter. Avoid mechanical influ-

ence on the sealing chamfers.

Step 3

Clamp sensor and adapter into a

clamping device (E). The sealing

chamfers (F) must not be dam-

aged. 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 only be connected by an 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.

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 mea-

suring 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).

Use with factory setting

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 para-

meter 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 analog value.

•Programming / remote programming of the sensor

Scaling the measuring range, damping for the analog output, cali-

bration 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 sen-

sor: Use a suitable power supply (24 V power supply; ifm order no.

E30067).

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

Disconnect power before connecting the unit.

Do not disconnect these connections while live.

Programming

A service program for the PC which is easy to use and self-explanatory

(order no. E30069) is available for the programming of the sensor.

Technical information / Functioning / Parameters

Lower end of analog output

Measured value for which the output signal is 4 mA.

Upper end of analog output

Measured value for which the output signal is 20 mA.

Minimum distance between ASP and AEP = 25%,

Calibration offset

The internal measured value (operating value of the sensor) is

offset against the real measured value.

• Setting range: -5 ... +5% of the value of the span

(with scaling as factory setting (ASP = 0% and AEP = 100%),

• in steps of 0.1% of the value of the span.

Calibration reset

Resets the calibration set by COF.

Min-Max memory for system pressure

• HI: displays the highest measured pressure.

• LO: displays the lowest measured pressure.

Damping for the analog output

Pressure peaks of short duration or high frequency can be filtered

out.

dAA-value = response time between pressure change and

change of the switching status in milliseconds (ms).

• setting range: 0 (= dAA is not active) / 0.1s / 0.5s / 2s.

Display unit

The measured values and values for ASP / AEP can be indicated

in the following units: mbar, kPA, inH2O, mmWS.

Select the display unit before setting the limits for the analog

output signal (ASP, AEP). This avoids rounding errors generated

internally during the conversion of the units and enables exact

setting of the limits for the analog output signal.
