I saved a Manson HCS-3602 from the dumpster. Labelled as Peaktech P1580, but that doesn't change much.
Manson Manual attached.
Technically it's in perfect condition, but it does have a software problem. Most likely the stored values are lost.
When powered on, it goes successfully through all tests.
It starts with 0 V, 0 A on the display. Then it says "UuL" or "UcL" when trying to select a voltage or current above 0. According to the Manson manual this means those limits have been set by software and can only be removed the same way.
The provided software doesn't connect. But I managed to connect via hterm and send commands, where the Power Supply answers.
The answer to "GMAX" is "000000", which is bad. Because these are the maximum values of voltage and current the Power supply can deliver. I assume originally this was factory set to the specific type of supply. So this brick now thinks it is a 0 V, 0 A supply. Any command to change voltage or current is only accepted when the value is 000.
The controller I see on the digital board is an Atmega 64A. No other digital chips, especially no EEPROMS.
So no way to set the values or to read them from a different device? Or was Manson so kind to not set the lock bits?
