It carries out its measure- ment 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 inter- nal 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 para- meter 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.

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

1. Screw the sensor into a G1

2. Tighten the sensor with a

spanner. Tightening torque: 20 Nm. The housing (A) is freely rotat- able. The unit is adaptable for various G1 process fittings (G1 adapters to be ordered separately as accessories). Welding adapter Weld the adapter first. Then mount the sensor.

Installationifm process 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). NOTE: A guarantee for a long- term stable sealing of the metal seal is only valid for once-only mounting. Mounting of the adapter Step 1 Screw the sensor into the adapter. Step 2 Clamp sensor and adapter into a clamping device (D). The sealing chamfers (E) must not be dam- aged. Tighten the sensor with a spanner. Tightening torque: 20 Nm.

41The unit must be connected by a suitably qualified 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 as follows:

ENGLISH Electrical connection Core colours of ifm sockets: 1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black).

Connector view (sensor)The unit can be electronically locked to prevent unwanted adjust- ment 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.

Mode/Enter Set Mode/Enter Set Mode/Enter Set Press the Mode/Enter button several times until the respective parameter is displayed. 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). Press the Mode/Enter button briefly (= acknowledgement). The parameter is displayed again, the set parameter value becomes effective.

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 set- ting of the values. If no button is pressed for 15s during the setting procedure, the unit returns to the Run mode with unchanged values.After mounting, wiring and setting check whether the unit operates correctly Faults displayed during operation Cleaning of the filter cover If viscous and residues producing media clog the filter cover of the sensor (and thus reduce the mea- suring accuracy slightly), you can clean it.

• Unscrew the filter cover (B) (use a pair of pliers with plas- tic-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).

Installation and set-up / operation Flashing: short circuit in the switching output 1*. Flashing: short circuit in the switching output 2*. Overload (above measuring range of the sensor). Underload (below measuring range of the sensor). Flashing: short circuit in both switching outputs*. *The output concerned is switched off as long as the short circuit exists.Adjustable parameters

Technical information / Functioning / Parameters Switch-on point 1 / 2 Upper limit value at which the output changes its switching status. SP2 is active only if OU2 = Hno, Hnc, Fno or Fnc. Switch-off point 1 / 2 Lower limit value at which the output changes its switching status. rPx is always lower than SPx. The unit only accepts values which are lower than SPx. Changing the switch-on point also changes the switch-off point (the distance between SPx and rPx remains constant). If the distance is higher than the new switch point, it is auto- matically reduced (rPx is set to the minimum setting value). rP2 is active only if OU2 = Hno, Hnc, Fno or Fnc. Setting range for SPx / rPx: → page 49. Configuration of output 1 4 switching functions can be set: - Hno = hysteresis / normally open

Hnc = hysteresis / normally closed

Fnc = window function / normally closed Analogue start point Measured value at which 4mA / 0V is provided. ASP is active only if OU2 = I or U. Analogue end point Measured value at which 20mA / 10V is provided. Minimum distance between ASP and AEP = 25% (scaling factor 4). AEP is active only if OU2 = I or U. Setting range for ASP / AEP: → page 49.

• HI: displays the highest measured pressure

• LO: displays the lowest measured pressure Erase the memory: - Press the "Mode/Enter" button until HI or LO is displayed. - Press the "Set" button and keep it pressed until “- - -” is displayed. - Then press the "Mode/Enter" button briefly. Calibration offset The internal measured value (operating value of the sensor) is offset against the real measured value.

• Setting range: -5 ... +5% of the value of the measuring range (with scaling as factory setting (ASP = 0% and AEP = 100%),

• in steps of 0.1% of the value of the measuring range. Calibration reset Resets the calibration set by COF to the value set at the factory. - Press the "Mode/Enter" button until CAr is displayed. - Press the "Set" button and keep it pressed until “- - -” is displayed. - Then press the "Mode/Enter" button briefly. Output polarity 2 options can be selected: - PnP = positive switching - nPn = negative switching This setting applies to both switching outputs. Delay time for the switching outputs dSx = switch-on delay; drx = switch-off delay The 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 / 0.1 ... 50s adjustable in steps 01s (0 = delay time not active),

• indicated in seconds. dS2 and dr2 are not active, if OU2 =

or U.30 Damping for the switching outputs Pressure peaks of short duration or high frequency can be filtered out. dAP-value = response time between pressure change and chan- ge of the switching status in seconds (s).

• Setting range: 0 ... 4s (0 = dAP is not active),

• in steps of 0.01s. Correlation between switching frequency and dAP: f max

Damping for the analogue signal Pressure peaks of short duration or high frequency can be filtered out. dAA-value = response time between pressure change and change of the switching status in seconds (s).

• Setting range: 0 (= dAA is not active) / 0.1s / 0.5s / 2s. dAA is active only if OU2 = I or U. 2 × dAP

Setting of the display 9 options can be selected: d1 = update of the measured value every 50ms d2 = update of the measured value every 200ms d3 = update of the measured value every 600ms The update interval only refers to the display. It has no effect on the outputs. ph = display of the measured peak value remains for a short time (peak hold). rd1, rd2, rd3, rph = display as d1, d2, d3, Ph; but rotated 180°. OFF = In the Run mode the display of the measured value is deactivated. If one of the buttons is pressed, the current measu- red 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. Display unit The measured value and the values for SPx / rPx can be display- ed in the following units: bAr (= bar / mbar), PA (= MPA / kPa), PSI, H2O (inH

O). 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 conversi- on of the units and enables exact setting of the values. Setting at the factory: Uni = bAr.Hysteresis function: The hysteresis keeps the switch- ing 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 sys- tem 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
