Does the control system have any means of defeating false alarms? Or, on the other hand, do the plant operators have any means of defeating true alarms?

no access to defeat false alarm.only atlas copco can modify or defeat.

Well, that's something. It shows there is a relationship with Atlas Copco. What else was discussed during the telephone calls to their Technical Helpline?

Try this:

Problem solving. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 42

If you downloaded the manual, you would see page 42. I noticed items on this page that refer the user to "Electronikon regulator manual" or other documentation. This might provide further insight about the messages appearing on your display.

Atlas Copco should be the most proficient at helping you, have you actually tried communicating with them?

What does your product manual have to say about this behavior?

Your alarm may be inferred by the controller, measuring the amount of time it takes to build up pressure when loading. Or it could measure the differential pressure across a screen or filter, and determine there is a higher than normal flow to atmosphere, when really the screen or the filter may be blocked, or some other problem that can fool the instrumentation(and the control designer).

So this alarm, perhaps poorly configured, may be triggered by any leak or wear in your compressor that results in a loss of performance.

It would be interesting to define what IC is an abbreviation for, that may provide more insight...

there are two condensate drain devices named as EWD ( electronic water drains) .one is for intercooler (IC) and other is aftercooler (AC).I am receiving "condensate drain IC open " alarm. I change the device but still alarm appears.I cheked in configuration.condensate drain IC contact should be closed and its open to alarm.in my case, it remains open all the time but when pressure reaches 7.8 bar during loading ,this alarm appears.

Malfunction: refer to dealer/OEM manual, and hash this out with them. They may have to send a field tech to solve it.

Maybe the intercooler has some plugging or blockage, or your pressure transmitter or switch before or after the cooler might be defective. Maybe your intercooler is cooling the air too much, or not enough, depending if they are using temperature or pressure to detect an air leak in the cooler.

My guess is that the control sees the pressure drop across the intercooler is higher than normal when loaded, which you might assume is due to higher than expected air flow into the cooler, or maybe slower than expected pressure rise into the cooler, root cause often an air leak, but maybe not always.

Manufacturers do not always document the method of obtaining alarms, makes it difficult to actually troubleshoot the alarm
