This chapter describes how to configure the device‘s alarm boundaries for min-/max-alarm-monitoring.
This instruction demands that you selected “AL.F1“ resp. “AL.F2“ as your desired output function like it is
explained in chapter 4.8.
- Press button 1 (if not already done) , the device will be displaying “AL.Hi“. (maximum alarm-value)
- Use button 2 and button 3 to set the desired value, the device should turn on its maximum-alarm.
- Press button 1 to validate your selection. The display shows “AL.Hi“ again.
- When pressing button 1 again, the device will be displaying “AL.Lo“. (minimum alarm-value)
- Use button 2 and button 3 to set the desired value, the device should turn on its minimum-alarm
- Press button 1 to validate your selection. The display shows “AL.Lo“ again.
- When pressing button 1 again, the device will be displaying “A.dEL“. (delay of the alarm-function)
- Use button 2 and button 3 to set the desired delay of the alarm-function.
Note: The unit of the value to be set is in [sec.]. The device will turn on the alarm after minimum
resp. maximum alarm value was active for the delay-time you have set.

Example: You want to have a temperature alarm-monitoring of a greenhouse. The alarm should start when
the temperature rises above 50°C resp. falls below 15°C.
Therefore your settings will be 50°C for the maximum alarm-value “AL.HI“ and 15°C for the mini-
mum
alarm-value “AL.Lo“.
The alarm will start after the temperature rises above 50°C and stays above 50°C for the entered
delay time resp. after it had been falling below 15°C and stays below 15°C for the entered delay
time.
Please note that the alarm-outputs are inverted! This means, that the output will be active when there is no
alarm!
Now you finished configuring your device. Press button 3 to switch over to display the measuring value.
