on page 3–7, whereas autovalidation with two gases requires four solenoids,
as shown in Figure 3–4 on page 3–8.

1. Open the analyzer enclosure cover according to the procedure under
“To open the analyzer enclosure cover” on page 3-3 to gain
access to the field interface terminal block.
2. Using a compound barrier seal gland (assembled per manufacturer
instructions), screw the gland into the M25 access port on the
bottom left of the enclosure. Make sure the STL8 lubricant is applied
to the thread before the gland is installed. Refer to “Application of
gland lubricant” on page 3-15.
3. Pull the solenoid valve cables into the electronics enclosure.
4. Strip back the jacket and insulation of the solenoid valve cables just
enough to connect to the appropriate terminals on the field interface
terminal block for your particular sample conditioning scheme, as
indicated in Table 3–1 below.
Certified glands and cables should be used where appropriate in
compliance with local regulations.
Hazardous voltage and risk of electric shock. Turn off and
lock out system power before opening the electronics enclosure
and making any connections.
Be sure to use solenoid valves rated for the output voltage of the
relays on your system. Failure to do so may result in fire.
For valve configurations refer to Figure 3–1 through Figure 3–4.
To avoid risk of a short circuit between adjacent connectors in
terminal blocks, ensure each wire uses a single compression-type
ferrule.
