Gas connection:
The gas supply lines between the device and the gas supply system are connected using the supplied
connecting hoses. CO
2
and O

/N

are supplied to the unit through dedicated connectors (2 and
3/
as well as 3/
).
All process gases must be supplied to the device at a fixed pressure that has been preset within a range of
0.8 to 1.0 bar (11.6 to 14.5 psi) and must remain unchanged.
Before the gases are fed into the workspace, they flow through a gas inlet filter with a separation rate of
99.998 % for a particle size of 0.3
µ
m (HEPA-filter quality).
The illustration shows the optional combined gas connection without the optional gas monitoring
system.
Label:
The label (4/
) contains information about gas supply, an alarm contact terminal legend, and
notes about the electrical fusing of the device.
USB interface:
The USB interface (5/
) allows for connecting the incubator to a PC. This connection - USB
1.1 / USB 2.0 / USB 3.0 full speed compatible - allows the fast (and temporary) acquisition of the
major operating parameters (temperature, CO
2
-/O
2
-/N
2
concentration, error codes, etc.).
4-20 mA interface:
The optional 4-20 mA interface (2/
) converts the digital actual values displayed for
temperature, CO
2
concentration, O
2
concentration (optional) and relative humidity into a continuous
output current of 4-20 mA each. This is accomplished by a microprocessor supported by a 4-channel
D/A converter. The D/A converter provides a resolution of 16 bit per channel, equivalent to 65536
incremental values.
The interface port accepts various customer-supplied external measurement devices with 4-20 mA
inputs - for example, the Thermo Scientific Smart-Vue Wireless Monitoring System (not supplied).
The table below lists the output signals:
