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

Use

...

Trouble shooting

See PowerNode White for details; or use the MENU button to see a QR code with logging. 

"net": "WiFi",
"ip": "192.168.6.91",
"mac": "34:98:7A:70:B0:E4",

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.

Somewhat unusual - this node is not fail-safe (i.e. if it crashes/reset - things are switched off); instead one relay is used to latch the safety on; the other relay needs an active pulse to break the interlock and switch things off.

The reason behind this is to not endanger the firing / interfere with the controls/safety of the oven as original designed.

Board jumpers and settings

Board:

  1. Rework 1 - half of OPTO resistors replaced by jumpers; 2x68k left in place
  2. Current coil
    1. White board - 6k8 burden
    2. Blue board - 68 Ohm
  3. Relay 1:
    1. White board: Normal 5v Songle relay
    2. Blue board:12v Schrack relay
  4. Relay 2:
    1. White board: Normal 5v Songle relay
    2. Blue board:12v Schrack relay
  5. Power
    1. White board: AC/DC unit soldered in
    2. Blue board: Power over Ethernet
  6. Fuse soldered in (100 mAmp, slow) on white board

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 (white board)

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.

kWh input =

S0 optocoupler output seems to need more than 5Volt; so 12Volt; with two resistors of 24k and 9k1 (of 33 en 12k) or there about.

Green Connector (blue board 0012)

PIN Description Use
1 CUR2 NC -- connector too small
2 CUR2 NC -- connector too small
3 OPTO4 TBD - N shared via jumper to pin 10 at back of board
4 OPTO3 TBD - N shared via jumper to pin 10 at back of board
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.
