On completion of the installation, the device can be switched on by applying the supply voltage. Starting sequence During the switching-on process, a segment test is performed for approx. 1 second, whereby all LED on the front (including switchpoint LED) are triggered.

    6. Operation and function description Optical response, display flashing The switching on of one or more setpoints can also be set to trigger a flashing of the display to enhance the optical response. Example: Let us assume the threshold for flashing of the display is set at setpoint 2. If setpoint 1 is exceeded and setpoint 2 is not, the setpoint LED 1 lights up permanently.

  • Page 16: Adjustment With 80%-Calibration (Ipm5)

    6. Operation and function decription 6.4.3 IPM5 calibration of mass pressure sensors Many standard sensors for mass pressure measurement have a special CAL wire. If this is connected to DMS-minus (Strain gauge minus), an unloaded bridge becomes so unbalanced that the signal value corresponds to an 80% load (80% is a standard value that can, however, be changed for the display).

  • Page 17: Automatical Calibration

    6. Operation and function description 6.4.5 Automatic calibration The IPM5 unit generally performs an automatic calibration. Depending on the setting, this can be triggered via the 4th key or the digital input. During calibration, the sensor must be free of pressure or the balance is without any load. Since, in the case of the IPW5, manual intervention is generally required, the semi-automatic calibration takes effect here.

  • Page 18: Interfaces Rs232 / Rs485

    6. Operation and function description 6.5 Interface All IPW5/IPM5 devices can be optionally programmed or configured via an interface. The devices do not have an interface as standard. Pressing the ENTER or <CR> key is always denoted by . Operation mode PN34 The interface can be operated in various modes that can be parameterised via the PN34.
  • Page 19 6. Operation and function description All values are written directly into the EEPROM of the unit and are valid after changing into operating mode. In contrast, the communication parameters of the interface only become effective after restarting the display. To simplify the input, there is no need for "." (dots) and "," (commas). In the basic setting, a message is not acknowledged, which enables the parallel programming of several displays.

    7. Programming 7.2 Linearisation With the linearisation, the IPM5 and IPW5 offer the possibility of linearising strain gauge sensors for the display of the measurements and their further processing (analogue output), in addition to the 2-point calibration, a maximum of 30 calibration points can be programmed.

  • Page 24: Programm Number Description

    8. Program number description 8. Program number description The IPM5 and IPW5 devices are parameterised or preset via program numbers because of the many different settings. Strain gauges PN0 With this program number, the sensitivity of the strain gauge can be selected.
  • Page 25 8. Program number description Taring function PN6 Suitable taring functions can be selected for various applications. These functions differ essentially in the method of saving the measured offset value. If no taring is selected, PN6=0, the offset value is always taken to be zero. With permanent taring, PN6=1, the measured offset value in program number PN5 is permanently saved in the user settings.
  • Page 26 8. Program number description Calibration mode PN9 A distinction is made between a variety of calibration modes. The preset input behaviour is also entered into the calibration as selected under PN0. With autocalibration to the calibration point (PN=0), a calibration is carried out only on PN1 (end value).
  • Page 27 8. Program number description Display time PN13 The display time can be set between 0.1 and 10.0 seconds, whereby the last measured measurement is taken over. There is no additional averaging for the display value beyond the individual measurement. If the measuring time is longer than the display time, the display change is delayed according to the set measuring time.
  • Page 28 8. Program number description Safety settings, user level PN50 bis PN53 With the parameters in the security settings, access to the program numbers is regulated through the setting of various user levels. The user levels divide the access into various levels. The user is only given access to the settings authorised by the system operator, such as the setting of thresholds.
  • Page 29 8. Program number description Threshold value behaviour of LED display PN59 In the event of a failure of the alarm outputs set under the setpoint parameters, a flashing of the display can be triggered in order to intensify the optical effect. The flashing of the display can be parameterised to the four different alarms.
