4-1. Operator interface
This section provides a survey of the operation of
the EXA operator interface. The basic procedures for
obtaining access to the three levels of operation are
described briefly. For a step-by-step guide to data
entry, refer to the relevant section of this user’s manu-
al. Figure 4-1 shows the EXA operator interface.
LEVEL 1: Maintenance
These functions are accessible by pushbutton
through a flexible front cover window. The functions
make up the normal day-to-day operations that an
operator may be required to complete. Adjustment
of the display and routine calibration are among the
features accessible in this way. (See table 4-1).
LEVEL 2: Commissioning
A second menu is exposed when the EXA front
cover is removed and the display board is revealed.
Users gain access to this menu by pressing the but-
ton marked * in the lower right of the display board.
This menu gives access to the service menu.
(See table 4-1).
LEVEL 3: Service
For more advanced configuration selections, press
the button marked *. Now push the “YES” button.
Selecting and entering “Service Code” numbers in
the commissioning menu provide access to the
more advanced functions. An explanation of the
Service Codes is listed in chapter 5 and an over-
view table is shown in chapter 11.
