Adjust with the calibration device
7.1 Calibration device
The calibration device (see Accessories on page 28) is
an additional device for calibrating the BTL if configuration
with a PC and software is not possible.
Prerequisite
– Button function has not been locked by the PC
software (button lock).
– Calibration device is in place
– The BTL is connected to the system controller.
– Voltage or current values from the BTL can be read
(using a multimeter or the system controller).
If the button function is locked, this lock must
be removed using the PC software.
Settings
The BTL has the following factory settings that can be
adjusted with the calibration device:
– One magnet,
– “position” function at both outputs, output 1 with a
rising curve and output 2 with a falling curve,
– identical measuring range for both outputs.
During adjustment, the same start points and end points
are set for both outputs. No other function can be selected
and no further transducer may be used.
If the button function is locked, the lock can only be
removed if these conditions have been fulfilled.
Use calibration device
DANGER
Explosions
Opening the housing can result in sparks which can
trigger explosions in explosive atmospheres.
►
Do not open housing when an explosive atmosphere
may be present!
Automatic deactivation!
If the buttons on the calibration device are not
pressed for approx. 10 min,
programming mode is automatically ended.
1. Unscrew and remove housing cover.
2. Slide calibration device into place.
3. Program BTL (see Sections 7 to 10).
4. Remove calibration device.
5. Re-install the housing cover flush and tighten to
33…40 Nm (25…30 ft ∙ lb). Tighten secondary
retaining screws (ATEX).
7.2 Calibration procedure notes
►
Before calibrating: Attach 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.
Values for null and end point
– Any desired position of the magnet can be used as the
null or end point. However, the null and end points may
not be reversed.
– The absolute null and end points must lie within the
minimum or maximum range of what can be output.
– The distance between the null point and end point
must be at least 4 mm.
The last set values are always saved, regardless
of whether the setting was ended using the
buttons or automatically after 10 min have
expired.
