Sitrep on Commissioning of the new SumpPi, which was started yesterday:
- Tthe new SumpPi Assembly was fitted into the IP65 box on site and the connections from the outside world screwed into the TB.
- ]The PoE injector was removed from the wiring and a new 12 V PSU installed inside the case.
- The PoE Splitter was removed from the old ButtsPi (now WButtsPi) and the unit fitted with a new 20 V PSU.
- The two encased units were tested on the bench with their Ethernet adaptor connected directly together. It was established that the Float Switch input and the SSR outputs were both behaving as expected.
- The two boxes were returned to their installed positions, the Ethernet cabling was connected and both units were switched on.
Two problems were encountered: first we couldn't establish communications with WButtsPi. It is believed that this was caused by the bad batch of Ethernet plugs that were used in the original assembly. By bypassing the suspect link proper comms was established.
The second problem is still outstanding. During normal operation, the Butts Pump seemed to be operating all the time, even when the Sump was nearly empty. The intention is to debug this tomorrow, with SumpPi connected to a monitor and keyboard. It is uncertain what is causing this because the Main and Butts Pumps both use the same piece of code to operate. However, I now recall that we had some problems with connecting up the wiring from the Float Switch, but there would also have to be a problem with the logic somewhere.
The new Hall Effect Probe seems to be working fine; see the attached Results File from the last run.
