4.1
Operator interface
This section provides an overview 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 instruction manual. Figure 4.1
shows the EXA operator interface.
l
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).
l
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 button marked * in the lower right of
the display board. This menu is used to set such values as the output ranges and hold and wash
features. It also gives access to the service menu. (See table 4.1).
l
LEVEL 3: Service
For more advanced configuration selections, press the button marked * , then press “NO”
repeatedly until you reach *SERV. 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 overview table is shown in chapter
10.
