PoE node voor the woodlathe based on a PowerNode White.
Use
Swipe your card; this will unlock the 'red' button on the safety contractor to the left. Note that the unit will refuse to power on if the on/off button on the saw is in the unsafe, ON, position.
Once you are done - switch off the saw and then press the green button on the safety contractor to disable it. The unit will lock shortly thereafter.
Trouble shooting
See PowerNode White for details; or use the MENU button to see a QR code with logging.
The log file is available on http://woodlathe.local/ or http://192.168.6.144/. One can also telnet to this address. Logs are also sent to MQTT and to Syslog at the firewall. Or connect a serial cable; but be sure to use a Galvanic USB isolator.
Configuration
The unit contains a AC fed PowerNode White that is on WiFi. This is done by a 5Volt AC/DC convertor on the board (the back thing in the bottom right). It has a single relay that simply turns one of the phases (L) on and off.
One of the 3-phase wires is routed through a current coil (directly; rather than through the connector; as there may be a fair but of current running through it). The opto couplers are wired to the pump and to the safety interlock.
The software can be found in ACNode its examples (in the Arduino IDE) or on GitHub.
