Installation & Operation Manual for the
Active Vibration Cancellation (AVC) System
AVC Controller & Over-Temp Thermistor
The AVC controller (figure 8) drives the AVC balancer as well as the cryocooler. A feature of the AVC controller
that is not among the features of the standard CryoTel controllers is the reject over-temperature alarm. A provided
thermistor (figure 9) is attached to the cooling fins via the available threaded hole (or near the water jacket via
thermal epoxy in the case of water cooled systems [figure 10]). If the thermistor reaches 70 °C during operation,
the controller will cut off power to the cryocooler until the temperature drops below 70 °C.
