9.5.4 Z/S Valves & IZS Permeation Tube Oven
The Z/S Valves and IZS are both options in the instrument. Before troubleshooting this sub-
assembly, check that the options were ordered, and that they are enabled in the software (if not
call factory).
Check for the Z/S valves:
1. Check for the physical presence of the valves. See Figure 2-5 for Z/S Valve location.
Check front panel for option presence. The front panel display when the instrument is in SAMPLE more
should display CALS and CALZ buttons on the second line of the display. The presence of the buttons
indicates that the option has been enabled in software.
Troubleshooting the Z/S valves.
It is possible to manually toggle each of the valves in the DIAGNOSTIC mode. Refer to Section 9.1.3
for information on using the DIAG mode. Also refer to Figure 8-3 for a pneumatic diagram of the
system.
Check for the IZS option:
1. Check for the physical presence of the IZS oven. See Figure 2-5 for the Z/S Valve location.
2. Check front panel TEST functions for presence of IZS temperature (if not call factory). If
IZS temperature is displayed, the IZS oven temperature control algorithm and temperature
display has been enabled in the software.
