CO= parameter settable from driver A or from driver B
8.3 Unit of measure
In the configuration parameters menu, with access by manufacturer
password, the user can choose the unit of measure for the driver:
• international system (°C, K, barg);
• imperial system (°F, psig).
Note: the units of measure K and R relate to degrees Kelvin or Rankine
adopted for measuring the superheat and the related parameters.
When changing the unit of measure, all the values of the parameters
saved on the driver and all the measurements read by the probes will
be recalculated. This means that when changing the units of measure,
control remains unaltered.
Example 1: The pressure read is 100 barg, this will be immediately
converted to the corresponding value of 1450 psig.
Example 2: The “superheat set point” parameter set to 10 K will be
immediately converted to the corresponding value of 18 °F.
Example 3: The “Temperature S4: maximum alarm value” parameter, set
to 150 °C, will be immediately converted to the corresponding value of
302 °F.
Note: due to limits in the internal arithmetic of the driver, pressure
values above 200 barg (2900 psig) and temperature values above 200 °C
(392 °F) cannot be converted
