  • Page 4: General Comments

    2. Range of Application The RT 45 control system was developed for use in temperature control units (hereafter referred to as “unit”). It enables dialog between one or more units and the processor of the production facility via an interface as well as operation independent of the processor.

  • Page 5: Switching On

    6 dots will appear in the two display fields (Section 6.1, display 1). If another display lights up, see Section 6.1. After the test has been run successfully, the dots will disappear; the RT 45 is ready for operation. In the right display field, “oFF” will appear.

  • Page 6: Switching Off

    “PtE” (see Section 7.2). The pump and control system are then switched off. The RT 45 switches to stand-by mode. All displays are extinguished, with the exception of the alarm display and “oFF”.

  • Page 7: Malfunction Displays

    SUCTION LEAK STOP Suction mode (except P 140S) or drainage by compressed air is activated when the upper lamp is lit. SUCTION LEAK STOP Leak-stop mode is activated when the lower lamp is lit (except P 140S). In normal operation, the temperature set value SP1 is displayed. Indicates the set value temperature when input externally (0 to 10 V or 0/4 to 20 mA).
  • Page 8 The display indicates when servicing is due (SErV). The display disappears when the unit is switched on via the “On/Off” key, but will reappear as soon as the unit is switched off. When servicing has been completed, the elapsed time to the next service must be entered (see Sec- tion 7.2, Programming “S.”).
