Alarm Low: If the measured value falls below the alarm low value,
the alarm relay is activated and E008 is displayed in the message
list.
Range: -10 to +20 °C
Case Temp. high: Set the alarm high value for temperature of elec-
tronics housing. If the value rises above the programmed value
E013 is issued.
Range: 30–75 °C
Case Temp. low: Set the alarm low value for temperature of elec-
tronics housing. If the value falls below the programmed value
E014 is issued.
Range: -10 to +20 °C
Relay 1 and 2: The function of relay contacts 1 or 2 is defined by
