2.4 Output
modes
The following output modes can be set for the four open collector outputs:
Output mode
Description
Standard output
Normal output mode for presence or direction detection
Group fault message
Output indicates loop faults from all loops
always off
Output always turned off
always on
Output always turned on
Simulation
Output switches constantly, e.g. for testing purposes
Inverted
or
non-inverted
signal output can be selected for all output modes.
In the case of standard output the loop faults of the respective channel can be output together with the
logical signal. Which fault is additionally indicated can be set to loop fault (break/short), loop frequency
outside frequency band and calibration procedure.
Factory default setting
: Standard
output,
Signals not inverted,
Respond to loop fault
The interface can be used to temporarily turn the outputs on or off. This allows you to implement control
tasks such as controlling traffic lights or variable message signs.
In simulation mode the output is constantly repeated according to the following scheme:
- The signal duration corresponds to the set minimum on duration
- The pause time corresponds to the set on delay. If no on-delay is set (0 ms), an idle time of 20s is
assumed.
For the factory set time behavior of the output signals this means a pulse signal of 200 ms duration and an
idle time of 20 s.
2.5 Time response of the output signals
On-delay, minimum on duration and off-delay for the hardware output signals can be set in 100 ms
increments over a range of 0...25500ms.
Factory default setting
:
On-delay 0 ms
Off-delay 0 ms
Minimum on duration 200 ms
