7.3.2 Switching behavior Min. alarm:
If the measured value falls below the limit value, the
alarm relay output switches to OFF. The LEDs K1 and
K2 light up red and the measured values flash in the
display.
Max. alarm, min. alarm
If set to the safety temperature limiter (STB) setting, this condition remains even when the main
measured value is back in the valid range. Only when the "Reset" key is pressed or a switch is
activated when the binary input is respectively configured will the alarm relay output switch on
again and the OK LED light up green.
When setting the safety temperature monitor (STW), the alarm relay output automatically
switches back to ON as soon as the main measured value is back within the valid range.
