Inversion
Selection
Description
Activated
This function enables the inversion of the switching state (instead of off,
on and vice versa).
Deactivated
If the inversion function is disabled, the switching state is transferred to
the digital output A1D without inversion according to the parameter
setting.
Hysteresis
The hysteresis is adjustable between 0.5…20 %.
Start up delay (SUD)
This function must not be used for safety applications (choose SUD = 0 s)
The SUD is adjustable between off…120 s.
Selection
Description
(Ex, NEx)
SUD (Start up delay)
SUD causes a delayed switching
behavior of [A1D] after detection of
a SUD condition. 0 s means SUD is
switched off.
0.0, 0.1, 0.5, 1.0, 5, 10, 30, 60, 90,
120 s
Fmax
Fmax the maximum frequency of the used sensor and adjustable between 0.1…20 kHz.
If the measured input frequency is higher than the adjusted value, the device falls into the safe
state.
Config
If the parameters are set, push config button between 2 and 6 seconds.
In this way the device takes over the set values.
If the button is pushed less than 2 seconds or more then 6 seconds, the new parameter set will
not be taken over and the “old” parameter set remains.
The successful take over will be signalized via LED (red LED is flashing 4 times).
As long as the config button is pushed, the device remains in the safe state.
You must not push config button during operation!
6.3.2
Parameter check
■
The proof test (see
„Appendix: Proof Test“ on page 22
) shall be executed in order to check
the requested function and parameterization.
■
The tests shall be executed even if the device was not parameterized.
■
Within the proof tests each relevant parameter shall be checked for correct function.
■
The device shall be locked against unintended operation/modification.
■
The device must not parameterized during operation.
■
The proof test shall be documented.
