1.1.2.2 Rear panel
All of the AS32M electrical connectors and gas inlets/outlets are located on the rear panel.
Gas inlets/outlets (right-hand side of the rear panel):
AS32M Standard model (see Figure 1–3):

The inlet for the sample to be analyzed (1) is composed of a fitting for a 4 mm (I.D.) and 6 mm
(O.D.) Teflon tube attached to the dust filter holder. The dust filter holder is equipped with a
Teflon filtering diaphragm called dust filter.

The pump outlet (3) to exhaust the analyzed sample consists of a 4 mm (I.D.) and 6 mm
(O.D.) Teflon fitting.
AS32M equipped with the solenoid valve option (see Figure 1–4):

The inlet for the sample to be analyzed (1) is composed of a fitting for a 4 mm (I.D.) and 6 mm
(O.D.) Teflon tube attached to the dust filter holder. The dust filter holder is equipped with a
Teflon filtering diaphragm called dust filter.

The pump outlet (3) to exhaust the analyzed sample consists of a 4 mm (I.D.) and 6 mm
(O.D.) Teflon fitting.

The span gas inlet (4) consists of a 4 mm (I.D.) and 6 mm (O.D.) Teflon fitting to connect an
outside span gas delivered at atmospheric pressure.

The zero air inlet (2) can be fitted with a zero air filter (12) or can be connected to an external
zero air generator.
AS32M equipped with the permeation bench option (see Figure 1–5):

The inlet for the sample to be analyzed (1) is composed of a fitting for a 4 mm (I.D.) and 6 mm
(O.D.) Teflon tube attached to the dust filter holder. The dust filter holder is equipped with a
Teflon filtering diaphragm called dust filter.

The pump outlet (3) to exhaust the analyzed sample consists of a 4 mm (I.D.) and 6 mm
(O.D.) Teflon fitting. This outlet should be connected to a filter cartridge containing active
carbon.

The « span gas inlet » is stopped up.

The "zero air inlet" (2) may be fitted with a zero air filter (12) or be connected to an external
zero air generator.

The "Zero air" inlet to supply the permeation bench. This inlet will be connected to external
dried zero air and delivered at the atmospheric pressure.
Electrical equipment and connections (left-hand side of the rear panel). The equipments
described below are common to the three versions of AS32M:

One mains power supply block consisting of a three-contact socket (6) to connect a standard
power cable and the general fuse (5): 1 A/230 V or 2 A/115 V (5).

One standard 25-pin DB25 plug (7) for serial links COM1 (RS232C – RS422) and COM 2
(RS232C) (see Table 3-1 – DB37 and DB25 connector links).

One standard 37-pin DB37 plug (8), if the ESTEL option is available (see Table 3-1 – DB37
and DB25 connector links).

One Ethernet output (10) and one USB port (11).
Ventilation device :
Internal aeration is done with a fan controlled by the module board based on the internal temperature
of the analyzer (9).
