Description
By setting the appropriate parameters, the controller can be programmed to execute many different functions.
The controller is programmed in three levels with the aid of the buttons on its front panel. Access to parameters which affect the safety of the system
is deliberately made difficult.
The first level permits access only to the setpoint and the alarm acknowledgement.
All regulation parameters (P2 - P32) can be set in the second level.
The third level permits programming of the basic functions (A1 – A92) of the controller.
