Operation and settings

The element is enabled for start and trip on the base of the direction setting for the two indepen-
dently programmable thresholds.
User can disable the 37P protection threshold from the keyboard. During this command, the trip
output relay (U <and / or U << thresholds) are forced to reset state, the message “Disabled 27-27V1-
37P-37Q” is displayed and all LEDs blink until the end of the command.
