5 .2 .2 Programming mode
Access to the function menus by the key Set.
•
In the switch function menu – password 1903 – all the adjustable parameter and functions are
chosen especially for the use of the device as switch.
•
In the transmitter function menu – password 3009 – all the adjustable parameter and
functions are chosen especially for the use of the device as transmitter by using the current
output.
•
In the switch point menu – password 1111 – only switch resp. switch back point of the PNP
switch output resp. outputs are accessible for fast adjustment. The function of the switch
outputs can be displayed.
5 .3 Switch output S1 / S2
5 .3 .1 Switch point / Reset switch point
The input values refer to the current measuring value or acc. to display scaling.
The reset switch point must be lower or equal to the switch point.
For both switch functions, there is no default minimum difference (hysteresis) between switch resp.
switch back point resp. between upper and lower switch point.
If the switch back point is set higher or equal to the switch point resp. the lower switch point is set
higher or equal to the upper switch point the switch back point is set automatically to the switch point
resp. the lower switch point is set automatically to the upper switch point.
The red error indication LED is flashing.
In the error memory service (
SEr
) / error memory (
ErrN
) there will be the indication of the
concerning switch output (
S1oG
or
S2oG
).
5 .3 .2 Switch delay time / Reset switch delay time
The activation resp. deactivation of the switch output can be biased with a delay time (resolution
0,1s), to realize simple sequence control system.
5 .3 .3 Operating mode
The operating mode defines the function direction of the switch output.
Normal Open / NO
•
At the output there is no signal, if the switch condition is not fulfilled.
•
At the output there is a signal, if the switch condition is fulfilled.
Normal Close / NC
•
At the output there is a signal, if the switch condition is not fulfilled.
•
At the output there is no signal, if the switch condition is fulfilled.
5 .3 .4 Hysteresis function
The hysteresis function realizes a stable switch state, independent from system conditioned signal
fluctuations around the adjusted set point.
It can be used for realizing a signal controlled two-position control.
The switch range is determined by input the switch point and switch back point.
The switch output is activated, if the current measuring value exceeds the switch point and if the set
switch point delay time has been expired.
The switch output is deactivated, if the current measuring value exceeds the reset switch point and if
the set reset switch point delay time has been expired.
The actual applied measuring signal can be applied or an arbitrary value can be set as switch resp.
switch back point.
