What does Kaeser alarm 0017 A (ADT safety shutdown) mean?
Short answer: ADT safety shutdown. If your Kaeser Sigma Control 2 is showing 0017 A — Safety shutdown ADT, the controller has logged a specific, documented condition. This page covers what it means, what causes it, what you can safely fix yourself, and when — and why — it takes a technician.
What exactly is the machine telling you?
A secondary safety trip because the maximum permissible airend discharge temperature was exceeded.
Which machines show this?
the wide range of current-generation Kaeser rotary screw compressors — ASD, BSD, CSD, DSD, ESD and related series — built since roughly 2011 with the Sigma Control 2, the industrial-PC controller with a text display and RFID access. It reports faults as a four-digit number plus a letter: 'A' messages are alarms that shut the machine down, 'W' messages are warnings or service reminders it keeps running through, with arrows marking whether the value went over or under its limit — so 0015 A is the airend-overheat shutdown while 0013 W just asks for an air filter. Practical tip: the same subsystem often has a W and an A code (0004 W before 0022 A on the separator); acting on the W message is how you avoid the A shutdown.
What causes it?
- The same overheat condition behind 0015 A tripping the secondary safety circuit
- Blocked cooling airflow or out-of-spec ambient conditions
- Dirty cooler or low cooling oil
Can you fix it yourself?
Partly — the same housekeeping applies: cooldown, cooler cleaning, oil level, ventilation. But a safety-level trip deserves more respect than a plain alarm.
Step by step — what to try, in order:
- Allow the machine to cool down.
- Keep ambient conditions within specified limits and verify cooling airflow is unobstructed.
- Clean the cooler.
- Check the cooling oil level.
When do you need a technician — and why?
A recurring safety shutdown means the temperature monitoring chain itself needs professional verification — you do not want to discover it failed the other way.
If it does come to a service call and you're in Nashville, TN or Birmingham, AL, we maintain independently compiled lists of local companies that service industrial air compressors — real businesses with verified contact information, none of whom paid to be listed.
