5.1.2 Alarm Parameters

Alarms Setup and Control – Example: Concentration Alarm Setup

¨Select the parameter you want in the menu "Alarms Setup", i.e. "Concentration", and change to the corresponding menu:

Note: If the setup of the parameter selected is not possible, a corresponding message will appear on the screen, i.e. no flow sensor installed to measure the flow.

1)Switch off the alarm control:

·Before beginning the alarm parameter setup, you have to select "Off" in the line "Alarm generation is".

·Otherwise, an alarm may start during the parameter will be configured.

2)Signal limits setup for alarm ("Level -1, ... , -4"):

·You can adjust four limit values for each signal parameter.

·You should fix the low alarm with "Level -2" and the high alarm with "Level -3". Then, you should save the low alarm with "Level -1" and the high alarm with "Level -4".

·The units and the possible range of values depend on the signal parameter selected.

·You also can adjust negative values:

Select the number with the 8 -key or the → -key and press F4 (+/-) to change the sign.

3)Conditions for alarm start ("Alarm-1, ... , -4 if signal is"):

·In these lines you can determine for which kind of exceeding each alarm shall be generated:

·Less: The alarm message will appear, if the value of the parameter selected is below the corresponding limit ("Level -1, ..., -4").

·Greater: The alarm message will appear, if the value of the parameter selected is above the corresponding limit.

4)Switch on the alarm control:

·Select one of the following set-ups to start the alarm control for the parameter limits selected:
