7. PASSWORDS

7.1

S3C PASSWORDS

Access to the S3C Case Control system configuration
parameters and service functions are password protected.
There are two levels of password protection; Administrator
and Technician. The Administrator password allows access
to all system control and configuration parameters for pur-
poses of setting up the S3C control system for an intended
application. The Technician password allows access to the
Service Menu where a service technician can access ser-
vice functions such as forcing a valve position or changing
operating modes (See Service Section). Parameter changes
made with the Administrator level are permanent whereas
Technician level changes are temporary and revert to their
original values when exiting the Service Menu. Passwords
are numeric and can range from 0 – 4999.

Note: The

default Administrator password is 19 and the default
Technician password is 81.

8. MENU STRUCTURE

The S3C Case Control system has a structured menu
design that allows Administrators and Service Technicians
to access key parameters independently. The structure
includes menus for the Case, Line-Up and Evaporator. Each
menu has viewable parameters related to that subsystem.
See following figure. Subsequent sections will define each
menu in more detail.

A new controller starts with the Set-Up menu. This enables
the product to be set-up through the display. The controller
may also go into the Set-Up menu after a factory reset.
See Service Section for more information on factory reset
option. After the control system has been set-up, it will enter
the “default display” which shows the case temperature
or mode of operation such as defrost. The default display
menu is read only and does not require a password. This
top level view may be used for a quick check on system
variables, such as case superheat or EEPR position. For
example, to view Case superheat:

From the
