Parameter validation
The CMS100 Nexo controller validates the parameter values that have been manually set by the user by
checking that the values do not clash with each other.
Below is the set of rules the controller validates the parameter values against:
1.
SP must be > dt t
2.
SSP must be > SP
3.
IPD must be > (SSP + Sd)
4.
IPd must be > dtd
5.
dtd must be > (SP + dIF)
If any of these rules are broken a warning will be shown on the display, in the form of the two clashing
parameters and three beeps of the buzzer.
The controller will display the clashing parameters when the back button is pressed (just before “byE” is
displayed and the controller reboots) when exiting the parameter listings.
The controller will only display one broken rule at a time even if all rules are broken.
Priority order as above.
