Therefore you have to select -15°C for the maximum alarm-
value “AL.Hi“ and -
30°C for the minimum alarm-
value “AL.Lo“.
=> The alarm will be starting after the temperature rises above -15°C and stays
above
-15°C for the entered delay time or after it had been falling below -30°C and
stays
below -30°C for the entered delay time.
Please note: The relay for alarm output (output 2) will be active if no alarm are exist. If an alarm condition
will occurred the relay will drop. For this function follows the following output states:
• no alarm
relay contact is open
• alarm
relay contact is closed
• power failed relay contact is closed
Now you finished configuring your device. Press button 1 to switch over to display the measuring 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)

Note: The unit of the value to be set [0 .. 9999] is in seconds. The device will turn on the
alarm after the minimum or maximum alarm value was active for the delay-time you
have set.
-
Press button 1 to validate the delay time. The display shows “
A.dEL
“ again.
Example: You want to have a temperature alarm-monitoring of a greenhouse. The alarm
should start when the temperature rises above 50°C or falls below 15°C.
Therefore your settings will be 50°C for the maximum alarm-
value “AL.HI“ and
15°C for the minimum alarm-
value “AL.Lo“.
=> The alarm will be starting after the temperature rises above 50°C and stays
above 50°C
for the entered delay time or after it had been falling below 15°C and stays be-
low 15°C
for the entered delay time.
Please note: When using the output function AL.F1 (common min-/max-alarm) both outputs will be active
parallel.
In consequence of the different contact types of the relay´s are both output contact states
available.
output 1
output 2
• no alarm
relay contact is closed
relay contact is open
• alarm
relay contact is open
relay contact is closed
• power fail
relay contact is open
relay contact is closed
Please note: When using the output function AL.F2 (individual max and min alarm) the outputs have fol-
lowing states:
AL.K,
AL.LO
A.DEL
