The limits for the desired MAX-Alarm value can be set in 1 %
steps from 0 % to 130 %. This value applies to both the forward

When MAX-Alarm is selected the contact is actuated when the
flowrate exceeds the limit value set. If this occurs, an upward
pointing blinking arrow is displayed.
MAX-Alarm limit value = 110 %
For flowrates >110 % a upward pointing blinking arrow is
displayed next to the flow direction indicator in the 1st line. If the
MAX-Alarm value is set to 0 %, the option is turned off and no
alarm arrow is displayed when the flowrate exceeds the value.
