Frequently Asked Questions - PF003A IFM

How to program the switching thresholds SP1 and rP1?

In Run mode, briefly press Mode/Enter to select the parameter (SP1, rP1). Hold Set for more than 5 seconds until the value flashes. Adjust with Set then confirm with Mode/Enter. Wait 15 seconds to return to Run mode.

What does the display 'OL' or 'UL' mean?

'OL' indicates overpressure (above the measuring range). 'UL' indicates underpressure (below). Check the applied pressure and the sensor's measuring range.

How to wire the sensor for PNP output?

Use standard pinout: 1 BN (L+), 2 WH (OUT2), 3 BU (L-), 4 BK (OUT1). For PNP, set parameter P-n to PnP. The outputs switch the positive.

How to set the analog output to 4...20 mA?

Set OU2 to 'I' (current). Adjust ASP for the minimum value (4 mA) and AEP for the maximum value (20 mA). The difference between ASP and AEP must be ≥ 25% of the range.

Why does the output not switch despite the pressure being reached?

Check the parameter OUx (Hno, Hnc, Fno, Fnc) and the thresholds SPx/rPx. Make sure the output is not short-circuited (message SCx) and that the delay dSx/drx is not active.

How to reset the stored max/min values (HILO)?

In Display mode, select HI or LO with Mode/Enter. Hold Set until '----' is displayed. Briefly press Mode/Enter to clear the memory.

What is the recommended tightening torque for the connection?

The maximum tightening torque is 20 Nm. Tighten the sensor with a suitable wrench at the G1 connection. Do not exceed to avoid damaging the seal.

How to clean the pressure compensation filter?

Unscrew the filter cover (B) with pliers with plastic jaws. Clean it carefully without pushing residues towards the vent (A). Screw back on. The sensor is IP67.

What to do in case of a flashing 'SC1' or 'SC2' message?

This indicates a short circuit on output 1 or 2. The output is disabled as long as the fault persists. Check the wiring and the load. After removal, the message disappears.

How to lock the keypad to prevent accidental changes?

In Run mode, simultaneously press both buttons (Mode/Enter and Set) for 10 seconds. The display briefly goes off to confirm. To unlock, repeat the operation.

Operating modes

Run mode

Normal operating mode

At power on the unit is in the Run mode. It carries out its measurement and evaluation functions and provides output signals according to the set parameters.

The display shows the current system pressure (can be deactivated; → page 30). The red LEDs indicate the switching state of the outputs.

Display mode

Indication of parameters and the set parameter values

When the "Mode/Enter" button is pressed briefly, the unit passes to the Display mode which allows parameter values to be read. The internal sensing, processing and output functions of the unit continue as if in Run mode.

• The parameter names are scrolled with each pressing of the "Mode/Enter" button.
• When the "Set" button is pressed briefly, the corresponding parameter value is displayed for 15s. After another 15s the unit returns to the Run mode.

Programming mode

Setting of the parameter values

While viewing a parameter value pressing the "Set" button for more than 5s causes the unit to enter the programming mode. You can alter the parameter value by pressing the "Set" button and confirm the new value by pressing the "Mode/Enter" button. The internal sensing, processing and output functions of the unit continue as if in Run mode with the original parameter values unless a new value is confirmed. The unit returns to the Run mode when no button has been pressed for 15s.

Programming

1				Press the Mode/Enter button several times until the respective parameter is displayed.
2		[BY3K]		Press the Set button and keep it pressed. The current parameter value flashes for 5s, then the value is increased* (incremental by pressing briefly or scrolling by holding pressed).
3				Press the Mode/Enter button briefly (= acknowledgement). The parameter is displayed again, the set parameter value becomes effective.
4	Change more parameters: Start again with step 1.			Finish programming: Wait for 15s or press the Mode/Enter button until the current measured value is indicated again.

*Decrease the value: Let the display of the parameter value move to the maximum setting value. Then the cycle starts again at the minimum setting value. Select the display unit (Uni) before setting the switch points (SPx, rPx) or the limits for the analogue output signal (ASP, AEP). This avoids rounding errors generated internally during the conversion of the units and enables exact setting of the values.

If no button is pressed for 15s during the setting procedure, the unit returns to the Run mode with unchanged values.

The unit can be electronically locked to prevent unwanted adjustment of the set parameters: Press both pushbuttons for 10s (the unit must be in Run mode). Indication goes out briefly (acknowledgement of locking / unlocking).

Units are delivered from the factory in the unlocked state.

With the unit in the locked state is indicated briefly when you try to change parameter values.

Installation and set-up / operation

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

Faults displayed during operation

OL	Overload (above measuring range of the sensor).
UL	Underload (below measuring range of the sensor).
SC1	Flashing: short circuit in the switching output 1*.
SC2	Flashing: short circuit in the switching output 2*.
SC	Flashing: short circuit in both switching outputs*.

*The output concerned is switched off as long as the short circuit exists.

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.

A B

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).

If one of the buttons is pressed, the current measured value is displayed for 15s. Another press of the Mode/Enter button opens the Display mode. The LEDs remain active even if the display is deactivated.
Uni	Display unitThe measured value and the values for SPx / rPx can be displayed in the following units:bAr (= bar / mbar), PA (= MPA / kPa), PSI, H2O (inH2O).Select the display unit before setting the switch points (SPx, rPx) and the limits for the analogue output signal (ASP, AEP). This avoids rounding errors generated internally during the conversion of the units and enables exact setting of the values.Setting at the factory: Uni = bAr.

Hysteresis function:

The hysteresis keeps the switching state of the output stable if the system pressure varies about the preset value. With the system pressure rising, the output switches when the switch-on point has been reached (SPx). With the system pressure falling the output does not switch back until the switch-off point (rPx) has been reached.

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

Window function

The window function enables the monitoring of a defined acceptable range. When the system pressure varies between the switch-on point (SPx) and the switch-off point (rPx), the output is switched (window function / NO) or not switched (window function / NC).

The width of the window can be set by means of the difference between SPx and rPx. SPx = upper value, rPx = lower value.

Scaling the measuring range (analogue output)

• With the parameter "Analogue start point" (ASP) the measured value at which the output signal is 4mA or 0V is defined.
• With the parameter "Analogue end point" (AEP) the measured value at which the output signal is 20mA or 10V is defined.
• Minimum distance between ASP and AEP = 25 % of the final value of the measuring range (scaling factor 4

Voltage output 0 ... 10V

MEW = final value of the measuring range

The output signal is between 0 and 10V in the set measuring range.

It is also indicated:

System pressure above the measuring range: output signal > 10V.

Current output 4 ... 20mA

MEW = final value of the measuring range

The output signal is between 4 and 20mA in the set measuring range.

It is also indicated:
