Each output range change, forces the device to properly reconfigure its output linearization. Notice that the output signal cannot get values outside the selected range, even if the application fluid exceeds the calibrated operating region. GELEC Industrial Electronics PAGE 8...
Page 9 PLC. The output signal value (min or max) during an Error state can be selected from the internal configuration dip-switch (SW4), depending on the application needs. Refer to the relevant section for more information. GELEC Industrial Electronics PAGE 9...
Page 10 Hardware failure or excessive applied pressure are the possible causes. Before replacing the damaged device with a new one, ensure that any possible problem that causes overpressure to the sensor (wrong connections/clogged pipes) is solved. GELEC Industrial Electronics PAGE 10...

However, if it is necessary adjust the regulator with a flat screwdriver (clockwise for decreasing, counterclockwise for increasing) and set the bubbles to the recommended rate. The front label may block the regulator access, for unintended adjustments protection. GELEC Industrial Electronics PAGE 11...
Page 12 This is an actual advantage only for 4-20mA / 0-20mA ranges. For the rest of the ranges the output value options are within the measuring range and cannot be utilized. Though, you can choose between minimum and maximum output, according to your application needs. GELEC Industrial Electronics PAGE 12...

The (S) adaptor is the input of the internal pressure sensor which measures the hydrostatic pressure. Check the pressure limits of your PIT7000 version before any connection. Excessive applied pressure can cause permanent damage, or degradation to the sensor. GELEC Industrial Electronics PAGE 13...
Page 14 Do not install the tube deeper than your PIT7000 version allows. The excessive applied pressure can cause permanent damage or degradation to the device’s pressure sensor. GELEC Industrial Electronics PAGE 14...
Page 15 Maintain the pneumatic circuit in good condition. Polluted air, dust, oil etc. inside the circuit may gradually affect the measurement, clog up the pipes, or even damage the device’s pressure sensor. Any air leakage along the (S) / (O) piping will affect the measurement. GELEC Industrial Electronics PAGE 15...
Page 16: Installation
Additionally, you can install the device at a point higher than your tank. If somehow fluid suction occurs, disconnect the (S) tube from PIT7000, clean it and confirm that the device works properly before using it again. GELEC Industrial Electronics PAGE 16...
Page 17 The shape of the tank must allow a linear relationship between the fluid volume and the measured level. Otherwise a proper software must be developed, which will automatically calculate the filled volume of the tank, depending on the output of the transmitter. Pneumatic Layout example GELEC Industrial Electronics PAGE 17...
Page 18 When you reach maximum output (e.g. 20mA in 4-20mA range), stop the filling.  ✓ This level is the maximum level that this specific fluid should reach during any process stage. Higher level than that, will expose the PIT7000 sensor beyond its operating pressure range. GELEC Industrial Electronics PAGE 18...

PIT7000-S1, or at a point with 50kPa (500cm water) for PIT7000-S5. Any modification of the calibration must be processed by an engineer familiar with the device operation, the associated equipment and the application in general. GELEC Industrial Electronics PAGE 24...
Page 25 (for example 4mA, if the selected range is 4-20mA). The two levels can be separately calibrated. You don’t have to calibrate both levels,  each time a change at one of them is needed. The device automatically reconfigures its output linearization. GELEC Industrial Electronics PAGE 25...
