UNPROTECTED PARAMETER MODE

The Unprotected Parameter Mode is accessed by pressing the PAR button

from the normal display mode with program disable inactive. In this mode,

the operator has access to the list of the most commonly modified controller

parameters. At the end of the list, a configuration “access point” allows the

operator to enter the configuration parameter modules. These modules allow

access to the fundamental set-up parameters of the controller. When the

program list has been scrolled through, the controller displays “End” and

returns to the normal display mode. The unit automatically returns to the

normal display mode if no action is taken.
