PARAMETER ADJUSTMENT
As delivered, the controller has the parameter settings specified in the Table 1. Parameter adjustment procedure:
•
press and hold the key (1) until the display shows the column with the code parameters;
•
select the desired parameter by pressing the keys (1) or (2);
•
press the key (3) to switch to parameter editing mode;
•
enter the desired parameter value by pressing the keys (1) or (2);
•
press the key (3) to record the value.
The controller will automatically exit the parameter setting mode if no keys are pressed.
