What does Atlas Copco GA 37/45 VSD converter alarm 0x2314 mean?
Short answer: Drive supply-voltage fault. If your Atlas Copco GA 37 VSD / GA 45 VSD (Elektronikon Graphic controller) is showing Converter alarm 0x2314, 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 converter alarm for which the instruction book's documented remedy is to check that the main supply voltage is within specification. The manual instructs contacting Atlas Copco if any other converter code appears.
Which machines show this?
Atlas Copco GA 37 VSD and GA 45 VSD variable-speed compressors with the Elektronikon Graphic controller. Because the motor is fed through a frequency converter, these machines add a second layer of fault reporting: alongside normal compressor messages, the drive raises converter alarms in hexadecimal — 0x1111, 0x2312, 0x2314 and similar — which the Elektronikon relays to the display. The instruction book documents remedies for only a handful of these and says to contact Atlas Copco for the rest. Practical tip: log the exact hex code and what was happening on the plant's power supply at that moment; most of these alarms trace back to supply-voltage quality rather than the compressor.
What causes it?
- Main supply voltage outside the compressor's nameplate specification
- A site power event (sag, spike, outage) just before the alarm
Can you fix it yourself?
No — beyond logging the code and conditions and one clean power cycle after a power event, the manual gives no user remedy.
Step by step — what to try, in order:
- Note the exact code and the conditions when it appeared
- Have the site supply voltage verified against the compressor's nameplate specification
- Try one clean power cycle after any site power event
When do you need a technician — and why?
Supply-voltage verification is electrician work, and if the code returns with voltage in spec the manual's only instruction is to contact Atlas Copco.
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.
