Page 3: Section 1, Equipment Description
Section 1 Equipment Description System Components The Sunpower Active Vibration Cancellation (AVC) system includes an AVC balancer, AVC controller, over- temp thermistor cable, accelerometer cable, power wiring harness, and instrumentation wiring harness as shown in figure 1. Figure 1. Active Vibration Cancellation (AVC) System Components... -
Page 4: Section 2, Installation
Section 2 Installation Install the AVC Balancer If a passive balancer is attached to the cryocooler, remove the bolt from the middle of the passive balancer and remove the passive balancer from the cryocooler. Now install the AVC balancer as follows: 1. -
Page 5: Install The Accelerometer
Install the Accelerometer Attach the AVC accelerometer (figure 4) (Sunpower part number 300AD-99678-108-015) to the end plate of the CryoTel cryocooler with the provided #5-40 bolt into the end plate of the cryocooler (figure 5). If the cryocooler is an older model not equipped with a #5-40 threaded hole, then use a small amount of super glue to attach the accelerometer onto the end plate in the location shown in figure 5. -
Page 6: Attach The Wiring Harnesses
Attach the Wiring Harnesses The components of the AVC system are interconnected with the cryocooler and with other interfacing equipment using the two supplied wiring harnesses: the power wiring harness, and the instrumentation wiring harness. Power Wiring Harness The power wiring harness (figure 6) has four connections: •... - Page 7 Instrumentation Wiring Harness The instrumentation wiring harness (figure 7) has five connections: • – A molded plastic, 9-pin, female RS-232 serial communications connector that con- Computer Connector nects to an RS-232 serial port on a computer for relaying control commands and replies. •...

Page 8: Avc Controller & Over-Temp Thermistor
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]). - Page 9 Figure 9.
