Calibration using online setting
NOTICE
Interference in function
Changing the BTL output signal may result in personal
injury and equipment damage if the system is ready for
operation.
► Persons must keep away from the system's
hazardous zones.
In online setting the system is not shut down. The start and
end values are set online.
Maximum setting range for each calibration
procedure:
Start value: ±25% of present stroke
End value: ±25% of present output value
If the desired value cannot be attained in the first
calibration procedure (max. setting range exceeded), the
calibration procedure must be started again.

After each calibration procedure you must wait
for the lockout time of 15s. This also applies to
switching between the start value and end
value setting.

decreased by approx. 1mV or 1 µA.
If a button is activated longer than 1 s, the step interval is
increased.
