WORK IN PROGRESS

PoE node voor the Ceramic Oven based on a PowerNode White. The QR code points to [this] page.

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://192.168.6.91/.

One can also telnet to this address. Logs are also sent to MQTT and to Syslog at the firewall. Or connect a USB cable; the use Galvanic USB isolator is wise; but not strictly needed (as it is AC/mains powered).

Configuration

See VK2000-build voor a lot of details.

Board jumpers and settings

Board:

  1. Rework 1 - half of OPTO resistors replaced by jumpers; 2x68k left in place
  2. Current coil - 6k8 burden
  3. Relay 1: Normal 5v Songle relay
  4. Relay 2: Normal 5v Songle relay
  5. AC/DC unit soldered in
  6. Fuse soldered in (100 mAmp, slow)

Jumpers:

  1. VPOE and VPOE5 both explicit on 'off'
  2. 5V power via VINT
  3. Vpower via VINT
  4. N-jumpers for the Optocouples to get the N from the inputs.

Green Connector

PIN Description Use
1 CUR2 NC -- connector too small
2 CUR2 NC -- connector too small
3 CUR1 NC - connector too small
4 CUR1 NC
5 OPTO 2 NC -- N for voltage sense is wired via jumper to pin 10 at back of board
6 OPTO 2 Voltage sense second relay VK2000
7 OPTO 1 NC -- N for voltage sense is wired via jumper to pin 10 at back of board
8 OPTO 1 Voltage sense safety relay coil
9 L input L AC in (brown)
10 N input N AC in (blue)
11 Relay 1 NO Start of safety relay
12 Relay 1 Common Start of safety relay
13 Relay 2 NO NC
14 Relay 2 NC Interlock, for stop
15 Relay 2 common Interlock, for stop

The heating current goes directly through the coil; we're not making use of the connector. Reason for this is that we're not quite sure of the (starting) currents.
