Applications

Type of pressure: relative pressure

	Measuring range	Order no.overl. pressure	Bursting pressure
PF30x3 0 ...	25 bar 100 bar 350	bar
PF30x4 0 ...	10 bar 50 bar 150	bar
PF30x6 0 ...	2,5 bar 20 bar 50	bar
PF30x7 0 ...	1 bar 10 bar 30	bar
PF30x8 0 ...	250 mbar	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 1% of the value of the measuring range. Display "0" does not mean that the system is free of pressure!

Hysteresis:

The hysteresis keeps the switching state of the output stable if the system pressure varies about the preset value. When the system pressure is rising, the output switches when the switch-on point has been reached (SP1); when the system pressure is falling again, the output switches back when the switch-off point (rP1) has been reached.

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

Window function:

The window function enables the monitoring of a defined acceptable range. When the system pressure varies between the switch-on point (SP1) and the switch-off point (rP1), 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 SP1 and rP1. SP1 = upper value, rP1 = lower value.

2. Operating modes

Run mode:

(Normal operating 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 parameters. The value of the analog output depends on the system pressure.

The display shows the current system pressure, the red LED indicates the switching state of the output.

Display mode:

(Indication of parameters and the set parameter values)

When the "Mode/Enter" button is pressed for a short time, the unit passes to the Display mode. Internally it remains in the operating mode. Irrespective of this the set parameter values can be read:

• The parameter names are scrolled with each pressing of the "Mode/Enter" button.
• When the "Set" button is pressed for a short time, the corresponding parameter value is displayed for approx. 5s; then the unit returns to the Run mode.

Programming mode:

(Setting of the parameter values)

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.

The unit is adaptable for various process fittings. ifm adapters to be ordered separately as accessories.

The housing (A) is freely rotatable.

Prozess adapter:

Mount adapter (C) to the sensor 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 fixing element (B) down over the top of the sensor: slide it up over the bottom of the sensor before the adapter is mounted.

Sensor and adapter are only to be mounted once.

If it is not possible to slide the fixing element (B) down over the top of the sensor: slide it up over the bottom of the sensor before the adapter is mounted.

Welding adapter:

Weld the adapter first. Then mount the sensor.

Mounting of the adapter Step 1

Grease thread and sealing chamfer of the sensor and of the adapter with the greasing paste supplied.

The greasing paste is food-grade (USDA-H1 84-201).

(Menu structure: see fold out page)

SP1

Switch-on point: Upper limit value at which the output changes its switching status.· setting range 1 ... 100% of the value of the measuring range· in steps of 0.5% of the value of the measuring range· indicated in bar

rP1

Switch-off point: Lower limit value at which the output changes its switching status.· setting range 0.5 ... 99.5% of the value of the measuring range· in steps of 0.5% of the value of the measuring range· indicated in barrP1 is always lower than SP1. The unit only accepts values which are 0.5% lower than SP1.Changing the switch-on point also changes the switch-off point (the distance between SP1 and rP1 remains constant).If the distance is higher than the new switch point, it is automatically reduced (rP1 is set to the minimum setting value).

d51dr1	Delay time for the switching outputdS1 = switch-on delay; dr1 = switch-off delayThe output does not immediately change its switching status when the switching condition is met but when the delay time has elapsed. If the switching condition is no longer met when the delay time has elapsed, the switching state of the output does not change.· setting range: 0 - 0.2 - 0.4 ... 9.8 - 10 - 11 - ... - 49 - 50s· in steps of 0.2 or 1s· indicated in seconds

6. Programming

Take the following 3 steps for programming:

1				Press the Mode/Enter button several times until the respective parameter is displayed.
2		[A235]		Press the Set button and keep it pressed. The current parameter value is indicated 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.
Wait 5s (the unit passes to the operating mode and the current measured value is indicated again), or start again with step 1 to program other parameters.

*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.

If no button is pressed for 20s during the setting procedure, the unit returns to the run mode.

Locking / Unlocking

The unit can be electronically locked to prevent unwanted adjustment of the set parameters: Press (in Run mode) both setting buttons for 10s. As soon as the indication goes out the unit is locked or unlocked. 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.

7. Installation and set-up / operation

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

Faults displayed during operation:

OL	= overload pressure(system pressure > 110% of the max. nominal pressure)
SCI	(flashing) = short-circuit in the switching output;the output is switched off

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.

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).
