Calibration Of The Pressure Transmitter; Configuring The Variable Frequency Drive; Setting The Working Point - S&P UTBS Serie Manuel D'installation

• Set the flow range and the parameter k: Press the "OK" button to access the airflow range
selection. Press again to access the individual digits of the parameter k, one by one, with the
option of selecting or not selecting a digit after the decimal point. Using buttons "" y "" you
can set the required values. Finally press "OK" to save the configuration and exit the settings
menu. The flow ranges which may be selected are as follow: 100 m

6.7.2.2.3 CalIBraTION Of THE PrEssUrE TraNsMITTEr (TDP-s aND TDP-D)
Once fully connected we recommend you carry out a zero calibration: After turning on the
equipment (the green LED is illuminated) wait a few moments until the transmitter reaches its
normal working temperature. Then press the zero set button. The yellow LED flashes until the
calibration process is complete. For a correct calibration, the pressure in the + and – terminals
must be the same. It is recommended that the tubes are disconnected.

6.7.2.3 CONfIGUrING THE VarIaBlE frEQUENCY DrIVE

The frequency inverter comes pre-configured by Soler&Palau to operate under constant pres-
sure or constant airflow and the only setting required is to configure the desired working point
frequency.

6.7.2.3.1 sETTING THE WOrKING POINT

The operating frequency range is preset by default between 20Hz and 50Hz. In some cir-
cumstances, the working point needs an output frequency higher than 50Hz, so that it is
necessary to reconfigure this parameter. resetting this parameter is only required if the
working point frequency is above 50Hz, otherwise it is not necessary. This data item can
be found in the equipment selections sheet and corresponds to the system's maximum
operating point. To make the adjustment, proceed as described below:
To move between the various menus, and between values of a parameter within a menu, turn
the wheel. To access a particular menu and to select the value of a parameter, press "ENT".
To return to the previous menu or to exit the selection of a parameter press "ESC".
