  • Page 10: Location Of The Probes

    1454H502 Ed.03 6.- Location of the probes 6.1.- Proportional mode WITHOUT FREQUENCY CONVERTER The controller activates (red line) or deactivates (green line) the different stages/compressors available in a linear manner depending on the reading obtained in probe 1 until the Set Point (E01) is reached again, as shown in the following figure.

  • Page 11: Neutral Zone Mode

    1454H502 Ed.03 6.2.- Neutral zone mode WITHOUT FREQUENCY CONVERTER In this mode, a neutral zone is defined, whose lower limit is the Set Point minus the bandwidth, and whose upper limit is the Set Point plus the bandwidth. While the reading of probe 1 remains in that zone, no stages or compressors are connected or disconnected.

  • Page 12: Pump Down

    1454H502 Ed.03 WITH FREQUENCY CONVERTER Operation is the same as in the previous point, but modulating the power of compressor 1 with the converter while it remains in the neutral zone using a PID control. Near the upper limit, the compressor operates at its maximum capacity, and if said limit is exceeded, more stages/compressors are added, in accordance with the interval defined in t02, until returning to the neutral zone.

  • Page 13: Fan Control

    1454H502 Ed.03 7.- Fan control 7.1.- Proportional mode WITHOUT FREQUENCY CONVERTER The controller activates (red line) or deactivates (green line) the different fans available in a linear manner depending on the reading obtained in probe 2 until the Set Point (E01) is reached again, as shown in the following figure.

  • Page 14: Neutral Zone Mode

    1454H502 Ed.03 7.2.- Neutral zone mode WITHOUT FREQUENCY CONVERTER In this mode, a neutral zone is defined, whose lower limit is the Set Point minus the bandwidth, and whose upper limit is the Set Point plus the bandwidth. While the reading of probe 2 remains in that zone, no fans are connected or disconnected.

  • Page 15: Floating Condensation

    1454H502 Ed.03 WITH FREQUENCY CONVERTER Operation is the same as in the previous point, but modulating the power of the fans with the converter while it remains in the neutral zone using a PID control. Near the upper limit, the fans operate at their maximum capacity, and if said limit is exceeded, the capacity is kept at its maximum until returning to the neutral zone.

    1454H502 Ed.03 9.- Parameter setup Through the programming menu users can set different parameters to adjust the operation of the controller to the needs of their installation. 9.1.- Programming Menu It allows changing the unit's operating parameters. To access the programming menu, press the SET button for 10 seconds, or until the "PRG" appears on the screen. IMPORTANT: If the password function has been configured, the system will demand entering the password programmed in L5.

    1454H502 Ed.03 9.2.- Parameters The unit's operation parameters are organized into groups or families according to their function. The Def. column shows factory-set default parameters. The pressure values featured on the table are expressed in bar and those for temperature in ºC. If the wizard meanwhile selects another set of units (parameter C09), the unit will make the conversion automatically.
