Frequently Asked Questions - PB0020 IFM

How to set the high set point (S)?

Press the SET S button for more than 5 seconds to enter programming mode. Then use SET S to increase the value (step by step or continuous) and confirm with ENTER S. The value is displayed via the green LEDs (steady + flashing).

How to set the low set point (R)?

Press SET R for more than 5 seconds to program the low point. Adjust with SET R and confirm with ENTER R. Note that S must always be greater than R.

What do the green and yellow LEDs mean?

The green LEDs indicate the current circuit pressure in 10 % steps. The yellow LED lights up when the output has switched (switching status).

How to lock or unlock the device?

Press both buttons (SET S and SET R) simultaneously for 10 seconds. The display briefly turns off to confirm locking or unlocking. In locked state, programming is impossible.

What to do if all LEDs are flashing?

This is a fault signal indicating a short circuit. Check the wiring and load. The device is protected against short circuits.

What are the available pressure ranges?

Depending on the variant: PB5xx0 (20-400 bar), PB5xx1 (12.5-250 bar), PB5xx2 (5-100 bar), PB5xx3 (1.25-25 bar), PB5xx4 (0.5-10 bar), PB5xx6 (0.125-2.5 bar), PB5xx7 (0.05-1.0 bar). The PB0020 model corresponds to one of these variants.

How to read the displayed pressure in 1 % steps?

By briefly pressing SET S or SET R, the display switches to Display mode. The value is the sum of the steady LED (integer value) and 1/10 of the flashing LED. For example, 30 bar + 0.8 bar = 30.8 bar.

Can the device be used with gases?

Yes, but the pressure is limited to a maximum of 25 bar for pressurized gaseous fluids. Check material compatibility.

What is the electrical connection?

The device uses an M12 connector with PNP or NPN output depending on the model. Observe wire colors (see diagram in the manual). The power supply must be SELV/PELV according to EN50178.

How to clean or maintain the sensor?

No particular maintenance is required. Avoid pressure peaks and shocks. For external cleaning, use a soft, dry cloth. Do not immerse (unless IP67 with accessories).

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).

IFM PB0020 - Function and features - 2

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)!

IFM PB0020 - Function and features - 3

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.

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.

scale value of the lit LED +1/10 of the scale value of the flashing LED ≧= displayed value

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

IFM PB0020 - Installation - 1

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

IFM PB0020 - Electrical connection - 1

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.

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.fter 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.
