Mounting / Installation (all device models)
Switching input
The DDLS 200 is equipped with a switching input IN, via which the transmitter/receiver unit can be
switched off, i.e. no infrared light is transmitted and at the bus terminals the corresponding bus bias
level is present / the bus driver is high impedance.
Input voltage:
(Relative to GND)
For easier operation, the switching input can be activated/deactivated via switch S1:
Position S1:
NOTE
When transmitter/receiver unit is switched off, the system behaves in the same way as in
the event of a light beam interruption (see chapter 11.4 "Operation").
The switching input can be used, for example, during a corridor change to completely
avoid interference effects from other sensors or the data transmission.
Switch S1 is also present on the device models with M12 connectors.
Switching output
The DDLS 200 is equipped with a switching output OUT WARN which is activated if the received sig-
nal level in the receiver drops.
Output voltage:
(Relative to GND)
The switching output is protected against: short-circuit, overcurrent, overvoltage, excess temperature
NOTE
The DDLS 200 is still completely functional when the received signal level drops to the
warning signal level. Checking the alignment, and, if applicable, a readjustment and/or
cleaning of the glass pane leads to a significant improvement of the received signal level.
18
0 ... 2 V DC: transmitter/receiver switched off, no transmission
18 ... 30VDC: Transmitter/receiver active, normal function
On the switching input is not analyzed. The transmitter/receiver
unit is always in operation (internal preselection of the switch-
ing input with Vin).
Off the switching input is analyzed. Depending on the input volt-
age, normal function or transmitter/receiver unit switched off.
0 ... 2VDC: operating range
Vin - 2VDC: Warning or shutoff range
