TOF/Spot
7.3

Analog output

Available for:
DC supply: Type A; no logic selector
The A type has an analog current output that is directly
related to the measured distance to the object in the
detection field. The value of the analog output has a range
of 4 ... 20 mA and corresponds directly to the measured
distance.
The value of the current output in regards of the distance
is as follows:
Current [mA]

The load needs to be a maximum of 250 Ω and leads to a
respective voltage output of 1 ... 5 VDC.

Test input

Available for:
All TOF/Spot-S with DC supply
The logic of the test signal is being recognized
automatically. This works as follows:
1. Connect the TOF/Spot-S with the controller.
2. Power up the controller.
3. The sensor recognizes the voltage level at the test input
during the power up time and sets the test to inactive.
From this point on, this level is used as "test inactive".
4. When the voltage level of the test input changes,
the sensor will recognize it as test signal (test active).
The sensor switches the output and the status LED
to "OBJECT DETECTED" (see Figure 25, Timing
diagram).
5. As soon as the voltage level of the test input switches
back to the initial level, the sensor returns to normal
operating mode. The output voltage level switches
back only if the background or an object is within
the operating range, but outside the switching level
(Detection field FREE).
Important:
 A test sequence must be implemented by the system
integrator to achieve safe operation according Cat. 2.
 The test signal has to be a DC signal, an AC signal
will not work.
 The test can only be used if the sensor has a permanent
background. If not, the test cannot be carried out.

8. Installation

It is recommended to carry out the system installation
according to the following steps:
1. Check if the scope of delivery is complete.
2. Mark clearly that the modifying system is out of service
and switch off main power and door control unit.
3. The installation place needs to fulfill the criteria
detailed in Chapter 5.1.
4. Drill a hole at the required position (see drilling
template for flush and surface mounting).
5. If needed, mount the mounting bracket.
6. Screw or snap in the sensor at the defined position.
7. Connect the TOF/Spot with the controller.

Mounting of snap-in housing

The mounting hole recommended for flush mounting is 30
to 31 mm. The sheet thickness cannot be greater 3 mm.
