Frequently Asked Questions - PB5024 IFM

How to set the high set point (S)?

Press and hold the SET S button until the desired value is reached. To increase step by step, press multiple times. Confirm by briefly pressing ENTER S.

How to set the low set point (R)?

Use the SET R button to set the value and ENTER R to confirm. The low set point must be lower than the high set point.

How to lock the device to prevent accidental programming?

Press both buttons simultaneously for about 10 seconds. The display turns off briefly to confirm locking/unlocking.

What is the meaning of the LEDs?

The green LEDs indicate the current circuit pressure (on) and the set point (flashing). The yellow LED indicates the switching status of the output (on if the output has switched).

What operating modes are available?

Three modes: Run Mode (normal operation), Display Mode (view set points), and Programming Mode (adjust set points).

Can this sensor be used for gaseous fluids?

Yes, but limited to a maximum pressure of 25 bar. Check material compatibility with the fluid.

What to do in case of short circuit?

In case of short circuit, all LEDs flash. The device is protected against short circuits and overloads. Check the wiring.

What is the required supply voltage?

The supply must be 18...30 V DC according to EN50178 (SELV, PELV). Current consumption is 50 mA.

How to mount the pressure sensor?

Ensure no pressure is applied to the circuit. Use an appropriate process connection (see label 'Port Size'). Tighten by hand, then with a suitable tool.

What are the important safety precautions?

Avoid static and dynamic pressure peaks exceeding the indicated overpressure. For gaseous fluids, do not exceed 25 bar. Mount and dismount the device pressure-free.

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 measured.

For gaseous media the application is limited to max. 25 bar.

1. Function and features

The pressure sensor detects whether a preset value has been reached or not and indicates this by a switched signal.

In addition a row of LEDs signals the current system pressure and the switch point (both in 10% steps).

= lit LED

= flashing LED

Applications (type of pressure: relative pressure):

	Measuring range	Order no. overl. pressure	Bursting pressure
PB5xx0 0 ...	400 bar 600 bar 1000 bar
PB5xx1 0 ...	250 bar 400 bar 850 bar
PB5xx2 0 ...	100 bar 300 bar 650 bar
PB5xx3 0 ...	25 bar 100 bar 350 bar
PB5xx4 0 ...	10 bar 50 bar 150 bar
PB5xx6 0 ...	2,5 bar 20 bar 50 bar
PB5xx7 0 ...	1 bar 10 bar 30 bar

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)!

Indication of the current system pressure as from 5% of the value of the measuring range. "All LEDs OUT" does not mean that the system is free of pressure!

The unit

can be used as N.O. or N.C.
- and operates with the hysteresis function.

When the system pressure is rising, the output switches when the switch-on point has been reached (S); when the system pressure is falling again, the output switches back when the switch-off point (R) has been reached.

The hysteresis can be set: First the switch-on point is set, then the switch-off point with the requested difference.

Setting range:

	Switch-on point (S)	Switch-off point (R)	in steps ofOrd
PB5xx0 20...400 bar 12...392	bar 4 bar
PB5xx1	12.5...250 bar 7.5...245 bar 2,5 bar
PB5xx2	5...100 bar 3...98 bar 1 bar
PB5xx3	1.25...25 bar 0.75...24.5 bar 0.25 bar
PB5xx4	0.5...10 bar 0.3...9.8 bar 0.1 bar
PB5xx6	0.125...2.5 bar 0.075...2.45 bar	0.025 bar
PB5xx7	0.05...1.0 bar	0.03...0.98 bar	0.01 bar

2. Operating modes

The unit has the following operating modes:

Run mode (normal operating mode), display mode (indication of the switch-on / switch-off point), programming mode (setting of the switch-on / switch-off point).

Run mode:

When the supply voltage has been applied, the unit is in the Run mode. It monitors and switches the transistor output according to the set hysteresis.

The green LEDs indicate the current system pressure, the yellow LED indicates the switching state of the output.

Display mode:

When the button "SET S" (or "SET R") is pressed for a short time, the unit passes to the Display mode. Internally it remains in the operating mode. Irrespective of this the switch-on / switch-off point can be read in 1% steps.

• When the button is pressed for a short time, the corresponding value is displayed for approx. 5s; then the unit returns to the Run mode.

Programming mode:

The unit passes to the programming mode when after the selection of a parameter value (Display mode) the "Set" button is pressed until the display of the parameter value is changed. Internally the unit remains in the operating mode. It continues its monitoring function with the existing parameters until the change has been terminated.

You can change the parameter value by pressing the "Set" button and confirm it by pressing the "Mode/Enter" button. The unit returns to the Run mode when no button has been pressed for 5s.

3. Installation

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

Mount the pressure sensor on a suitable process connection (see type label "Port Size").

4. 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.

5. Programming

Increase the switch-on point / switch-off point

1

Press the SET S-button* and keep it pressed until the requested switch point is displayed. As soon as the LED starts moving the switch point can be increased (incremental by pressing briefly or scrolling by holding pressed).

→

After 5s the flashing LED moves from left to right. → 10 20 30 40 50 60 70 80 90 100 UT 10 20 30 40 50 60 70 80 90 100 UT after LED 9 has been reached the cycle starts again at LED 0. The LED which is constantly lit moves on by one position.**

2

Press the ENTER S-button* briefly (acknowledgement).

→

The set switch point becomes effective; the unit passes into the operating mode.

• SET R button to set the switch-off point

ENTER R button to acknowledge the setting of the switch-off point

The switch-on point (S) is always higher than the switch-off point (R). The unit does not accept values for R which are higher than S.

**Overflow: If the flashing LED and the lit LED exceed the maximum setting value, the cycle starts again at the minimum setting value.

Decrease the switch-on point / switch-off point

Let the flashing and lit LEDs move to the maximum setting value. Then the cycle starts again at the minimum setting value.

Locking / Unlocking

The unit can be electronically locked to prevent unwanted adjustment of the set parameters: Press both pushbuttons for 10s. Indication goes out briefly (acknowledgement of locking / unlocking). Units are delivered from the factory in the unlocked state.

6. Commissioning / Operation

After mounting, wiring and setting check whether the unit operates correctly. Faults displayed during operation: All LEDs flashing in case of short-circuit.
