Frequently Asked Questions - PB5021 IFM

How to set the high set point (S)?
Press the SET S button for more than 5 seconds to enter programming mode. Keep it pressed until the desired value is reached (continuous increase or step by step). Confirm by briefly pressing ENTER S.
How to set the low set point (R)?
Press the SET R button for more than 5 seconds. Set the value by holding the button, then confirm with ENTER R. Note that the high set point must always be higher than the low set point.
What to do if all LEDs flash?
Flashing of all LEDs indicates a short circuit at the output. Check the wiring and eliminate the fault.
What is the required supply voltage?
The device requires a DC voltage of 18 to 30 V DC (according to EN50178, SELV/PELV).
How to lock the sensor to prevent unintentional adjustment?
Press both buttons simultaneously (SET S and SET R) for 10 seconds. The LEDs briefly turn off to confirm locking/unlocking.
What is the meaning of the green and yellow LEDs?
The green LEDs indicate the current circuit pressure in 10% increments. The yellow LED lights up when the output switches (N.O. or N.C. state).
Can the sensor be used with pressurized gaseous fluids?
Yes, but pressure is limited to 25 bar maximum for gases. Check material compatibility with the fluid.
How to read the pressure displayed on the LED bar?
The displayed value corresponds to the sum of the value of the steady LED and 1/10 of the value of the flashing LED. For example, for a 100 bar model, if LED 3 is steady and LED 8 is flashing, the pressure is 30 + 8 = 38 bar.
What is the maximum output current?
The output current is limited to 250 mA. The output is protected against short circuits and overloads.
How to clean the sensor?
Use a dry, non-abrasive cloth. Do not use solvents or aggressive chemicals.

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 PB5021 - 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 PB5021 - 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.

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.

5. Programming

Increase the switch-on point / switch-off point

1IFM PB5021 - Increase the switch-on point / switch-off point - 1Press 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).IFM PB5021 - Increase the switch-on point / switch-off point - 2After 5s the flashing LED moves from left to right.IFM PB5021 - Increase the switch-on point / switch-off point - 3fter LED 9 has been reached the cycle starts again at LED 0. The LED which is constantly lit moves on by one position.**
2IFM PB5021 - Increase the switch-on point / switch-off point - 4Press 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.
