Satiator charger troubleshooting

Troubleshooting

Unfortunately, there have been two issues that affected our late 2016 / early 2017 production of Satiator devices. If you have a unit that displays either of the symptoms below, then please contact Grin immediately and we will arrange for a warranty repair or replacement

The first of these is caused by a high percentage of faulty tank capacitors from the manufacturer, and would result in the the screen showing "Pwr Fault Error, Restart" whenever the Satiator attempted charging. Prior to this point the Satiator would have been working perfectly fine for any number of weeks or months. This is a sign that one or more of the film capacitors has failed in an open circuit, and must to be returned to Grin for repair.

If you see a "Pwr Fault Error", but after unplugging and reconnecting AC power the Satiator runs and charges fine, then that is normally the result of a brief hiccup in the AC supply line or a BMS circuit that was repeatedly tripping and resetting during the charge process.

The second issue was a potential failure of the soft start circuitry in place to prevent the electrical spark on connecting the Satiator to a battery pack. This would result in a message "shorted - 0V" on the Satiator screen when it is connected with no battery attached. However, the Satiator could still charge the batteries just fine if the battery was first connected while in the profile selection menu.

The cause of this failure was isolated to plug connections that exhibited a certain timing of electrical contact bounce and it has been prevented with the V1.025 firmware update. If you are running the V1.024 or earlier firmware we recommend updating to 1.025 right away to prevent this from occurring. Otherwise if you have a device with this issue, contact Grin and they will get it fixed.
