Normally, a SmartSensor Matrix sensor will send 10 contact closure messages each second.
If a rack card does not receive communications from a sensor within 10 seconds, the rack
card will go into fail-safe mode and all of the contact closures will be activated and the cor-
responding detection channel LEDs on the faceplate will turn on.
Attaching and Programming the Click 104
Use the following steps to set up the DIN rail contact closure module for each sensor:
1 Mount the Click 104 on a DIN rail over a T-bus connector. is connects the device’s
control bus (bus 2) to the installation’s shared communication bus; you can connect
your computer to another device on this shared bus, such as the Click 305 USB con-
verter, to access the Click 104 to congure it using Click Supervisor. Mounting the
Click 104 on the T-bus also connects it to the power source.
