ProLogic
Figure 7.15: ProLogic
ProLogic is used to create an output based on multiple inputs. Five user programmable ProLogic
control statements can be utilized to create custom logic and operate output contacts. User can
define or name the function being created and set a pickup and dropout delay. Each ProLogic
statement can be used with internal relay functions and external inputs (up to 5 possible inputs)
to create the logic output by using Boolean logics such as AND/ OR, NAND/NOR, XOR/NXOR and
LATCH.
The output of ProLogic 1 can be nested into ProLogic 2 and so on. If desired, user can illuminate
the front target LED on operation of this function by enabling this feature in Output Matrix / LED
Output menu. The operations of the ProLogic statements are logged on the events listing. The
status of the Prologic can be seen from the LCD/HMI metering menu.
Reset
The relay reset screen allows user can choose the reset type of relay either Self Reset / Hand
Reset. If the Self Reset is chosen then the relay reset will happen as per the dropout timer settings
(range is 0.00 to 1.00 seconds).
