Installation
If this I/O Module is received as a sepa-
rate unit, carefully examine the shipping
carton and contents for signs of damage.
Immediately notify the shipping carrier if
the carton or contents is damaged. Retain
the carton and packing material until all
components are operational.
To install this I/O Module, follow general
installation guidelines in Section 2 and
then bind each Analyzer module to the
System Auto Cal I/O Module. Do this
through each Analyzer module's menu
structure. See binding in Section 2 for
details.
Configure System Auto Cal parameters
as follows:
1. Enter the System Auto Cal Module
menu structure by making selec-
tions in the following path: Main
Menu, Expert Controls and Setup
menu, Auxiliary Module Controls or
Auxiliary Module Setup menus, and
[choose] System Auto Cal [module].
2. In the Auxiliary Module Controls
menu and subsequent submenus,
set parameters relative to calibration
gas selection and calibration mode
(local/remote/external). Local and
remote selections allow the operator
to switch between a local calibration
gas injection point and a remote
one. This choice sets the dwell time
according to the distance that the
calibration gas must travel. The ex-
ternal selection allows the use of an
external digital signal carried by
digital line 4 (for instance, from a
simple front panel switch) to quickly
set either local or remote mode.
3. In the Auxiliary Module Setup menu
and subsequent submenus, set ad-
ditional parameters such as se-
quencing cycles, valve control for
zero and span gases, Analyzer
identification and range upper/lower
limits, and zero vs. span check ratio.
NOTE
In the Timing parameters screen, the
following should be considered: If
Start sequence at this time - Day of
month is 0, calibration will occur every
day and If Calibration cycle period is 0,
auto cal is disabled.
