Calibration device

The calibration device is an additional device for calibrating
the BTL.
► Before calibrating: Place the calibration device on the
connection side of the BTL.
► When finished with calibration: Remove the calibration
device to prevent changes.
► Keep the calibration device for later use.
Automatic deactivation!
If the buttons on the calibration device are not
pressed for approx. 10 min,
programming mode is automatically ended.

6.2 Programming inputs
(not for BTL7-...-S135)
Instead of the calibration device, the programming inputs
may also be used for setup.
– La corresponds to button 1,
– Lb corresponds to button 2,
– Programming input at 20 to 28 V (BTL7-_1_ _-...) or
10 to 30 V (BTL7-_5_ _-...) corresponds to button
depressed (high active).

The detailed procedure for teach-in is described
on page 17.
Steps:
► Move magnet to the new null position.
► Read new zero point by pressing the buttons.
