9.3.9 Defining changeover of the check programs
In Process mode, you can switch between the
Rack Near
and
Rack Far
check programs.
Select
CONFIGURATION > DEVICE > Digital I/Os > General parameters
.
The
CONFIGURATION OF DIGITAL I/OS
dialog is displayed.

Activate the
Automatic program change
checkbox for changing the check programs via digital switching
inputs IO2 and IO3.
The signals for program selection on the inputs must currently be applied.
• If the signals are removed at the inputs while the
Automatic program change
checkbox is selected,
the device interprets this as a “logical low” pending signal and activates the check program with
selection ID 0 (
Near Rack
).
• If the
Automatic program change
checkbox is not selected, the check program confirmation must be
performed via a “program change” input.
Define the
Delay time - program selection input
.
The delay time defines the time that the input signals must be applied to the device before a change to
an edge results in a change of check program. The delay time protects against faulty activations since
it takes up to 300 ms for the check program to changeover.
For technical reasons, it is not possible to implement an immediate changeover (delay time = 0 ms). If
the delay time is set to 0 ms, the functionality is deactivated. This corresponds to unselecting the
Auto
-
matic program change
checkbox.
9.3.10 Configuring the digital switching inputs/outputs
The digital switching inputs/outputs are configured for the active check program via the

NOTICE
Adjust limit values if the tolerance areas are changed!
If the tolerance areas change in the application, the limit values in the
Measurement - Evaluation
dialog
must be checked and adjusted if necessary.
The minimum value for this application is 2 mm.
