Shutting Down the RSA-G2
To shut down the RSA-G2, simply press and release the standby button on the front panel. This will safely
power down the instrument as soon as the oven comes down to a safe operating temperature. At that point,
the power shuts down and the power light turns red, indicating that the instrument is now in the standby
state. Press and hold the standby button to cause the instrument to immediately go into the standby state.
Before switching the system to the standby state, all test sample materials should be removed from test fix
-
tures, and the transducer should be moved into a position where the upper test fixture is not in contact with
the lower test fixture. (When power is restored, the motor performs a calibration operation that requires
free motor shaft displacement.)
If an error occurs that causes the instrument to not switch into the standby state, the standby button can be
pressed continuously for 10 seconds to force an unconditional shutdown.
Powering “Off” the RSA-G2
If the instrument is expected to be disassembled for maintenance, disconnected from its compressed air
source, or is being moved, then it is necessary to turn the power to the system completely off. Please follow
these guidelines:
• A rocker switch/ circuit-breaker located on the lower part of the rear panel on the power controller
removes all power from all components plugged into the power controller.
• Please make every effort to put the instrument into the “Standby” state before disconnecting power.
Switching off the power while the system is operating may damage electronics or mechanical systems.
• Removing power from the system will cause some settings (specifically the Gap-Zero measurement)
to be lost. It will be necessary to re-zero the test fixture after power is restored.
• Power should be turned off and the system unplugged from the mains-power-source if there is a rea -
sonable expectation of a large electrical disturbance on the mains power source. (Severe weather,
anticipated power outage, utility work, or anticipated extraordinary power-line transients.)
• Removing power from the system is not recommended as a daily practice; it is preferable to leave the
system in its “Standby” state unless there is a specific reason to completely remove power.
