AK-LM 340

Temperature alarms

1. Go to Configuration menu

2. Select Temperature alarms

3. Temperature alarms

3. Temperature alarms

The function monitors a temperature and issues an 

alarm if the set value is exceeded.

• Name

• Temp. input select

• Alarm limit

• Alarm type

Define whether the alarm is to be activated at 

temperatures that are too high or too low. 

• Alarm delay

Time delay before the alarm becomes active

• Alarm text

• DI-signal 

Here a DI signal can be selected, which can stop 

the alarm from the function.

We have not used this function in our 

example. The image is included for guidance 

only.
