To activate the
compensator the threshold which is to be

be activated. With the setting of Cl 94 = 100 %
(factory setting) the
compensator is disconnected from
the dancer-Position controller.

Select the freely assignable terminal which is to be assigned to the
function “diameter compensator reset” via

is assigned to the freely assignable terminal
Cl 13. If
the
compensator is enabled via the freely assignable
terminal, the thresholds will be compared first. When activating the
