- if parameters alarm is active, check and correct all the parameters of temperature and pressure,
cancel the alarm leading to 1 bit 0 of the variable Command (Cmd), and then reset the
EVDRIVE03
- if parameters alarm is cleared check ParS variable and if necessary, reset the board again.
It is recommended not to abuse the automatic conversion of the parameters: is a delicate function as its disruption
can lead to the invalidation of all the memory parameters.
In addition, repetitive conversions lead to a subsequent loss of precision in the values.
The Internal unit of measure (UdM) indicates which units of measurements are actually used, since the parameters
Ph60 and Ph61 may have been changed. After the reset and the automatic conversion the Internal unit of measure
(UdM) mirrors the parameters.
Given that, as stated earlier, the internal algorithm work in Kelvin, Celsius and BarA, if the units of measurement
chosen match these, no conversions are performed. If the user's units of measurements are in Fahrenheit and / or Psi,
the following conversions are applied:
Param. in °F/R/PSI > val. in °C/K/bar > algorithm > val. out °C/K/bar > var. out °F/R/PSI.
