2.5. Logic functions
The device supports customer-defined logics. The logics are
designed by using the VAMPSET setting tool and downloaded
to the terminal. For detailed information, please refer to the
VAMPSET manual (VMV.EN0xx).
2.6. Programmable alarm functions
Power monitoring unit has eight identical programmable alarm
stages (ALARM STAGE 1-8). All alarm stages can be enabled
or disabled one by one from the menu (Alrm/ALARM 1...ENA)
to fit the intended application. All the enabled alarm stages
have the following programmable parameters:
• Link_: link to a measured or calculated value, see table
below.
• Cmp_: mode (< or >)
• Set_: alarm limit of stage_ (setting range depends on the
signal)
• t: delay 0.5 - 300.0 s, step 0.1 s
• Hyst_: hysteresis 1.0 - 10,0%, step 0.1%
• NoCmp_: no compare limit (visible only for active < mode)
