JUMO 701150 14597 safetyM STB/STW - Safety Temperature Limiter and Safety Temperature Monitor Operating Manual - Manual (Page 78)

7 Configuration level 2014-05-01 78
Max. alarm:
If the measured value exceeds the limit value, the alarm
relay output switches OFF. The LEDs K1 and K2 light
up red and the measured values flash in the display.
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.
