The bottom screw terminals are also labeled 1–8 and represent the secondary outputs, with
secondary one (S1) representing the lane closest to the SmartSensor. The remaining four
screw terminal connections are labeled GND and are a common logic ground for all 16
contact closure outputs. You must provide a connection from the GND terminals to a logic
ground to make the primary and secondary outputs operational.
The screw terminal connectors can also be unplugged from the Click 100 allowing you to
pre-wire the Click 100 before final installation.
Configuration Features
The four LEDs located right below the push-button are used to indicate operation modes,
which will be discussed later in the On-device Configuration section of this chapter. Below
is a list of the four LEDs:
˽ PR (Presence) – Red
˽ PU (Pulse) – Orange
