If the "absolute" warning alarm has been set (C119 =1), value VA for the warning alarm must be checked when
changing from inverse to direct. Once the change is made, this is less than the limit value and falls within the alarm
range.

Comment
If the value falls below limit AL, the fitted relay switches OFF. LED K1 shows red and the limit
flashes in the display.
The temperature limiter remains in this state, even if the measured value rises above limit
AL. Only when a tool has been used to press the "Reset" key or if a switch has been operated
by a relevant configuration of the binary input, does the relay switch back ON and LED K1
shows green.
The temperature monitor automatically switches the relay back ON and LED K1 shows
green, when the measured value rises above limit AL.
