  • Page 87 TresCon UNO Operation Relay Time [s] Fig. 5-7 Relay output of the pulse-width controller The cycle duration (T) is made up of the turn-on and turn-off switching duration (t ) of the relay together. While the selected cycle dura- tion (T) remains constant, the turn-on duration (t ) changes depen- ding on the measured value and, with it, the pulse width (v).
  • Page 88 Operation TresCon UNO Frequency controller Switching frequency control is used, e.g. for controlling dosing pumps. In contrast to the pulse-width controller, the frequency controller is not modulated by the pulse width, but by the switching frequency of the out- put signal. Depending on the position of the measured value in the pro- portional range, the relay is switched more often or less often.

    TresCon UNO Appendix 8.4.2 RS commands for modem With an existing connection to the TresCon UNO, the following com- mands can be used in addition to the normal RS commands: msidnt With this command, you can allocate a designation to the TresCon. This designation is automatically sent along with a call or with call- backs.
  • Page 194 Appendix TresCon UNO Example: Entering "69" for the Type of analyzer module means: 69 = 1 + 4 + 64, i. e. TresCon should transmit the module mode, fluid levels and calib- ration data for the analyzer module 1. mscall TresCon can dial a number and transmit data at freely selectable inter- vals.

  • Page 196 Appendix TresCon UNO The callback is deactivated by sending the command, "mserrcall0,0". It can also be deactivated in the menu for initiali- zing the modem (Deactivating of modem). When doing so, all settings are deactivated. Note Before setting up the connection for the modem the modem is always reinitialized.
