13.2.3
State Sensor Error
If the connection to a sensor involved in temperature regulation gets lost then the BSVT goes
into the sensor error state. However, if only one sensor of a double sensor adapter (e. g.
TC-2T) is used, then the according channel runs in single sensor mode, and the unconnected
sensor is not considered.
13.2.4
State Gas Flow Error
There are two possible types of gas flow errors - either the VT gas flow is blocked
somewhere between the SPB and probe (VT gas tube, chiller, etc) or in the probe itself or the
gas supply is too weak or out of order. In both cases, the BSVT goes into the gas flow error
state. The gas flow status indicates the exact error type (blocked or missing). As soon as the
VT gas flow has recovered (e. g. interrupted gas supply has been re-established and the
required standby gas flow has been reached), the BSVT control goes back to the off state.
There is a maximum gas pressure that can be adjusted in the Service Web - the VT gas flow
regulation guarantees that this maximum pressure is never exceeded even if the VT gas is
blocked somewhere.
13.2.5
State Self-Test
If there is a problem - e. g. the BSVT refuses to go into operation or some connected devices
do not behave as expected, it is recommended to run a self-test. The self-test can be started
on the Service Web and may last some seconds (it may be useful to check the state until the
self-test is complete). In the end, there is a short self-test report available, providing
information about all connected devices and their status (e. g. missing sensor connections,
missing gas flow, and so on).
13.3
Specific Configurations
In the following subsections there are a few specific configurations described.
13.3.1
BSVT with CryoProbes
CryoProbes in cold state cool down the sample if there is no active VT operation. In this
configuration, the auxiliary gas of the BSVT (which is designed for flushing of the RF section
of room temperature probes), is used as a safety gas flow in order to prevent from sample
freezing, in case the BSVT system was powered down.
