6.2 Configuration of a pressure or a temperature probe type at X61 door
ATTENTION:
If the external load controller is set do not connected to terminals X60 or X61.
If a modulation probe is connected to the X61 terminal, proceeding as follows:

0…20 mA Set the proper value according to the probe
output.
6.2.1 Configuration of a pressure or a temperature probe signal at X61 door
Once the pressure sensor signal type is set, the sensor range must be set as well, proceeding as follows:

Params&Display Menu level for making the parameter
settings

End of pressure measuring range for input
X61
0...99.9 bar
0...2000 °C 0...99.9 bar
0...2000 °C Set the probe value
Example:
if a max 10bar Siemens sensor is used, the voltage output signal will be 0 V at 0 bar, while the 10 V signal will correspond to its maximum
pressure 10 bar. If the sensor is replaced with a max 16bar one, the 0 V output signal will correspond to 0 bar, while the 10 V output signal will correspond
to 16bar pressure: the parameter “MRange Press-Sens” has to be set at 16bar.
6.3 Configuration of the X62 door input signal
Following the below route access to the programming levels of the menu by means the Esc

If a boiler second probe is to be connected to terminals (1000 Ohm only), internal functions TL_ThreshOff and DiffIntervTL_SD_On are activated
automatically (see paragraph SETTING FUNCTIONS “TL_ThreshOff” AND “TL_SD_On”).
