Node Ceramic

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://ceramics.local/ or http://192.168.6.??/. 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

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.
