Communication failure: Communication failures may occur in two specific situations, as detailed below.
1) Normal failure: When the generator is connected to DELTA Max or DELTA Pro, if the generator goes
into sleep mode, a communication failure will occur. In this situation, press a button to activate the
generator and the communication failure will disappear.
2) Abnormal failure: If the communication failure does not disappear once the generator has been
activated or while the generator is running, this could indicate that the failure has been caused by a
problem with the generator.
If any alert occurs during the use of this product and if the alert icon does not disappear after the
foregoing methods are attempted or the product is restarted, please stop using it immediately.
If the above information still fails to solve your problem, please contact our professional service
personnel for further support.
