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