6 Test
The following test should be conducted only when used as a safety sensor of the
door controller in complying with German standard DIN 18650.

Pulse Diagram of Time Sequence

If the TopScan-S is used as a safety device, the device has to be tested cyclically by the door control-
ler. This test should be conducted only if no object is detected, and the recommended door position
for the test is completely open.
The door controller's test signal should be connected to the master module's 6-position screw terminal
only.
Test Description:
Time t : The door controller sends the test request input.
0
Time t : After a response time of no more than 70 ms, the sensor output must go into detection mode.
1
Time t : After 200 ms, the sensor output must remain in detection mode.
2
The test input signal can now be turned off by the door controller.
The test is now completed. After another 70 ms, the sensor will be available again.

Connection to the Door Controller

The inside and outside of the door has to be switched on and off alternately (muting) -> or has to be
excluded from the evaluation of the door control.
If the device is not used as a safety sensor in complying with German standard DIN 18650, the test
input can be left unconnected.
If the modules on the inside and outside of the door are connected to a door tran-
sitioncable, special cable ties (e.g.: 3M Scotchlok single core tie UB2) are recom-
mended where another cable can be added to the supply cable.
