INSTRUMENT DESCRIPTION
The Series 4000
Integrale
comprises of one self-contained monitor unit, housing both the
dewpoint sensing assembly and all the control and monitoring functions within one unit.
The
Integrale
monitor unit is constructed in a 19" 3U sub-rack enclosure, and requires
only mains power supply and sample gas connections for operation. Refer to Appendix
1.0 for S4000
Integrale
Front and Rear Panel Layout Diagrams and Section 5 for
Technical Specification.
2.1
Front Panel
The dewpoint sensor is located on the left side of the monitor as viewed from the front,
next to the GAS IN and GAS OUT ports and integral flowmeter.
On the right of the monitor are the user controls and displays. These include the power
switch, the LED displays and display selection push-buttons, the MAX COOL pushbutton,
the DATA HOLD LED indicator, the ABC STATUS LED indicator, the OPERATION /
STANDBY switch, and the ABC INITIATE push button.
2.2
Rear Panel
It is important that air flow to the two vents located on the rear panel of the monitor not be
obstructed. The operation of the instrument will be adversely affected by preventing
sufficient cooling flow.
All user input and output connectors are available on the rear panel of the monitor. These
include RS232 interface, User I/O, and remote pressure input (if required). In addition,
the sensor heat pump overload fuse, DIP switches SW2, SW3, and SW4 and the power
connector are located on the rear panel.
2.3
Dewpoint Sensor
The mirror and optics within the sensor, may be accessed from the front of the instrument
for cleaning and maintenance purposes by unscrewing and removing the microscope
housing.
The black blanking plug may be removed from the sensor and a microscope attached to
the sensor assembly to allow the formation of ice crystals to be observed by the operator.
Refer to Section 4.6.
