    4.1. Scale Scaling consists of assigning a display value to each input signal value. With MICRA-E it is achieved by programming two Direct scale Reversed scale coordinates (input1, display1) and (input2, display2), between which is established a linear relation where to each input signal value corresponds a display value.

Once completed the instrument programming we recommend the following security measures be taken: Lock out the programming access to prevent from programmed parameters modifications. Lock out keyboard functions to prevent from accidental modifications.

    7.1 –SETPOINTS OUTPUT 7.1.1 – Introduction An option of 2 or 4 SETPOINTS, programmable within the full display range, can be incorporated to the unit thus providing alarm and control capabilities by means of individual LED indicators and relay or transistor outputs. All the setpoints provide independently programmable value, time delay (in seconds), asymmetrical or symmetrical hysteresis (in counts of display) and selectable HI/LO acting.

  • Page 35: Functioning Description

    7.1.2 –Description of operation As programmed like independent setpoints, the alarm outputs activate when the display value reaches the user-programmed value. The independent alarms programming requires definition of the following basic parameters: a. HI/ LO ACTING MODE. In HI mode, the output activates when the display value exceeds the setpoint level and in LO mode, the output activates when the display value falls below the setpoint b.

    Each output card is supplied with an adhesive label that indicates the wiring connections of each option. To help identifying each terminal, this label should be placed in the lower side of the meter case, beside the basic functions label. NOTE: In case that the outputs are used to drive inductive loads, it is recommended to add an RC network between the coil terminals (preferably) or between the relay contacts to limit electromagnetic effects.
