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.
1. Set start value online:
► Move the system so that the magnet is in the start
position.
► Activate a

► Exit setting (do not activate a button for at least 15 s).
⇒ The start value is saved, the buttons are deactivated.
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.
2. Set end value online:
► Move the system so that the magnet is in the end
position.
► Activate b
for at least 3 s.
