  • Page 20: A) Range Parameters

    PRESYS  Instruments PCON-Y18-LP a) Range Parameters WARNING! Before connecting the instrument under test to the output port it is recommended to configure the output range parameters. These parameters limit the controller output range, in order to protect the instrument under test.

  • Page 21: B) Changing The Setpoint

    PRESYS  Instruments PCON-Y18-LP b) Changing the set point Press the SP button or touch the Indicated Value to change the set point to the desired value. When the pressure is stabilized, its reading value turns to green. Fig. 16 - Control Mode – Changing Set point Value The state of the output isolation valve is user configurable.

  • Page 22: C) Stabilization Settings

    Fig. 18 - Stabilization Settings d) Control Settings The PCON-Y18-LP has a linear controller output behavior when the set point is changed. It means that the output varies linearly according to the parameter SP Slew Rate (Pressure Unit / second). The controlled pressure will be closer to the linear behavior for lower values of pressure rate, protecting the instrument under test from overshoot.
  • Page 23 PRESYS  Instruments PCON-Y18-LP Edit the Control Parameter by pressing the SETTINGS button shown below. Go to the CONTROL tab and edit the SP Slew Rate (in current pressure unit / second). Fig. 20 - Control Parameters Increasing the flow the output tends to be more stable, but it may cause overshoot.

  • Page 24: E) Preset Setpoints

    Another fast way to change the set point to the preset values is using a numeric keyboard connected to the PCON-Y18-LP Type A USB (see section 1.5 – Parts Identification). In Control Mode, when pressing from 0 to 7 in the keyboard the corresponding preset set points P1 to P8 will be controlled.

  • Page 29: Changing The Engineering Unit

    PRESYS  Instruments PCON-Y18-LP When the VENT mode is started, first the calibrator reads the pressure in the control module. If the pressure measurement is below the Vent Opening Limit value, the control is shut off and the VENT valve opens. Otherwise, if the pressure is above this limit, the controller reduces the pressure down to the Vent Opening Limit value by varying it according to the Vent Rate parameter.
