Wiring
- N and single 220volt L via switch; black and blue
- 2x for the thermocouple - orange cable; white and brown
- 2x Normally open relays to switch a load contactor
- Earth wire
On a Harting HAN7Da connector.
Sensor
- Nenniger GmbH, Berlin, Hochtemperatur S-Type Thermocouple
- Special type of cable for this (orange)
Risks
Inherent
- Heat runaway (CPU fault, contacts welded)
- Faulty thermocouple causing heat runaway / instability / cracking
- Contact with water/leak
- Material falling onto it / other people working too near / unclear that is hot
Operator driven
- Flammable material near
- Hot handles, etc
- Dust
- Unclear it is on / hot
- Opening while hot
- Bare wire touching
- Looking into it / infrared radiation
