CHAPTER 9
• CLICK 110
Fault latching involves how the Click 110 reacts when the flow of data from the connected
SmartSensor is interrupted. As mentioned in the Fail-safe Mode section above, if the Click
110 does not receive a datagram containing a channel that is mapped to its outputs for ten
seconds, the device will enter fail-safe mode.
In fail-safe mode, all enabled outputs will assert a detection and fault condition. The master
fault output will also assert. As long as the flow of data is reestablished within one minute,
the device will exit the mode and continue normal operation. How the device reacts when
data flow is not reestablished is determined by whether fault latch is enabled or disabled.
If S3:8 is on (up), fault latching is disabled. This means that if the Click 110 starts to receive
data again at any point after the one-minute mark, the device will exit fail-safe mode and
continue normal operation. If S3:8 is off (down), fault latching is enabled. In this case, if the
fault condition has existed for more than one minute, normal mode can only be restored by
rebooting (front panel reset switch, power cycle, or remote reset via outstation), even if the
device has started to receive data again.

Table 9.6 – DIP Switch Fault Latch Settings
Because fault latching can only be changed using the DIP switches, there is no need (and no
option) for selecting Hardware or Software configuration modes.
Front Panel Menu
The front panel of the device features two push-buttons and four banks of LEDs for on-
device configuration and monitoring. The first two banks of LEDs, labeled Detection and
Fault, and the lower push-button, labeled Reset, are for basic monitoring and configuration
and are explained in the Physical Features section.
The two lower banks of LEDs, labeled Menu, and the first push-button, labeled Mode
Switch, are used for navigating through Menu mode. This section will cover how to use
these features and the menu to configure the Click 110.
The lower bank of LEDs will be referred to as Level 1 and is used is selecting menu options.
The upper bank will be referred to as Level 2 and is used in configuring the menu options.
