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 user's manual. Figure 4-1 shows the EXA operator inter-

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).

A second menu is exposed when the EXA front cover is removed and the display board is revealed.

This menu is used to set such values as the output ranges and hold features. It also gives access to the
service menu. (See table 4-1).
LEVEL 3: Service
For more advanced configuration selections, press the button marked

bers in the commissioning menu provide access to the more advanced functions. An explanation of the
