• Typical heater circuitry does not route wires such that the controls (thermostats) are within wire bundles between the thermostat and the heater.
• As an example, wake radiator examples are provided on the following pages.

• TRD heater circuitry does not route wires such that the controls (thermostats) are within wire bundles between the thermostat and the heater.
• Additional controls (i.e. valve control lines) are physically bundled in separate cable harnesses.

AMS02 Channelization SummaryCCEB System Circuits
• J-Crate monitors GTSN temperature and removes PDS power (SSPC) to CCEB in over-temperature condition.
• J-Crate monitors GTSN temperature and uses USCM control of CCEB to ramp-down Cryocooler power in over-temperature condition.
• Internal and external Cryocooler sensors are monitored by independent sensors (in a physically separate cable harness – from above and eachother) and this data is used by separate subsystem in the CCEB to regulate power via PWM to Cryocooler
CCEB utilizes independent means of controlling Cryocooler operation / maximum temperature:
