A1 DRY RUNNING
Failure verification
Final failure
If the system detects dry running during more than 10 seconds, it will stop the
pump and the ART (Automatic ResetTest) will be activated.
After 5 minutes, the ART system will start the pump again for 30 seconds, in an
attempt to restore the system.
In case of persistent lack of water, it will try it again every 30 minutes for 24 hours.
If after all these cycles , the system still detects lack of water, pumps will remain
permanently out of order until the fault is resolved.
Dry running, it has been activated the safety system: you should verify the feeding
of the hydraulic network. The pumps can be primed using the push-button
START/STOP ( the led light AUTOMATIC should be off, if it is not, press the push-
button to disable it).
Special case: If the pump cannot provide the programmed pressure (configuration
mistake) the Speedmatic reacts as it was dry-running.
