What temperature does the Heater and Fan turn on and off a Optera
By design the Optera camera hardware is operating normal.
There are two temperature domains on Optera: processor and imaging. The processor domain controls one fan, and the fan will kick on if the FPGA die temperature sensor is >= 90C (194F). The fan will go off once this sensor reads <85C (185F).
The imaging domain controls two fans in round-robin/failover mode and one heater. This fan comes on if any imager temperature sensor is >= 80C(176F) and is turned off when all imager temperature sensors are <75C (167F).
The heater is turned on if any imager temperature sensor is < 30C(86F), and it will turn off when all temperature sensors are > 45C(113F).
