1.1.2.3. Rear panel
All of the AF22e electrical connectors and gas inlets/outlets are located on the rear panel. Refer to
Figure 1–4.
Gas inlets/outlets for standard analyzers (right-hand side) :

The inlet for the sample to be analyzed (1) is composed of 4 mm (I.D.) and 6 mm (O.D.) Teflon tube
fittings, attached to the dust filter holder. The dust filter holder is equipped with a Teflon filtering
diaphragm.

The pump outlet (2), to exhaust the analyzed sample, consists of 4 mm (I.D.) and 6 mm (O.D.)
Teflon fitting.

A fan (9).

The span gas inlet (3) is composed of 4 mm (I.D.) and 6 mm (O.D.) Teflon fitting to connect an
external span gas at atmospheric pressure.
The following internal option is also located on the rear panel:

The “zero” optional inlet (4) is composed of 4 mm (I.D.) and 6 mm (O.D.) pneumatic tube fitting. It is
used to connect an external, SO
2
-free, “zero air” supply at atmospheric pressure.
Gas inlets/outlets for analyzers with permeation bench option (right-hand side):

The inlet for the sample to be analyzed (1) is composed of 4 mm (I.D.) and 6 mm (O.D.) Teflon tube
fittings, attached to the dust filter holder. The dust filter holder is equipped with a Teflon filtering
diaphragm.

The pump outlet (2), to exhaust the analyzed sample, consists of 4 mm (I.D.) and 6 mm (O.D.)
Teflon fitting.

A fan (9).

The span gas inlet (3) is stopped up.

The zero air inlet for permeation bench (12).
The following internal options are also located on the rear panel:

The “zero” optional inlet (4) is composed of 4 mm (I.D.) and 6 mm (O.D.) pneumatic tube fitting. It is
used to connect an external, SO
2
-free, “zero air” supply at atmospheric pressure.
Electrical equipment and connections for all analyzers (left-hand side):

One main power supply block consisting of a three-contact socket (5) to connect a standard power
cable and the general fuse (6): 3.15 A/250 V.

One Ethernet output (7) and two USB ports (8).

One 4-point BL connection to connect the optional solenoid valve for external calibration (10),

One connection for the 24 V power supply for ESTEL board option (11).
